contained in any Nortel Networks or third party “shrink wrap” or “click” licenses shall govern the use of such software. 

  

	4.8	If Nortel Networks and Customer agree that delivery of Software is to be made electronically via File Transfer Protocol, then delivery of such Software by Nortel Networks shall be
deemed to have taken place at such time as the Software is loaded onto a network server, as designated by Nortel Networks, and Customer has been provided with appropriate instructions and passwords to enable Customer to begin use of such Software.
Notwithstanding the foregoing, the Parties shall comply with all regulations applicable to importation of Software pursuant to applicable law.

	5.3	Except for the Orders for RSSs mentioned in Section 5.21 below, all Orders for Products shall be accompanied by: (i) payment of seventy percent (70%) of the purchase price thereof
upon delivery of the Order through a wire transfer of immediately available funds or by a letter of credit or by any other mutually agreed means; and (ii) within the next five (5) days after delivery of the respective invoice as per Section 5.2

	5.4	Payment of this thirty percent (30%) shall be made by Customer ten (10) days after Delivery Date (as defined in Annex E of this Agreement) of the Products; provided that
Customer may notify Nortel Networks in writing within such 10-day period if some or all of the Products delivered are not in compliance with the terms of the Order (the “Non-Compliant Products”), in which case Nortel Networks shall
take, within thirty days of the date of Customer’s notice, corrective action to resolve such Non-Compliant Products. Customer shall not be obligated to pay, and Nortel Networks shall not be entitled to draw on the letter of credit or other form
of payment guarantee, the purchase price of the Non-Compliant Products until Nortel Networks corrects such non-compliance, provided, however, that prior to such resolution Nortel Networks shall issue a revised invoice relating to the
portion of Products received by Customer that is in compliance with the terms of the Order. Partial shipments shall be allowed under this Agreement, subject to the terms set forth in Annex “J” of this Agreement. For the avoidance of
doubt, the Parties agree that the purchase price of the compliant Products shall be paid by Customer as provided in this Section 5.4.

directly or indirectly by Nortel Networks) and shall, at Nortel Networks’ direction, promptly pay to Nortel Networks or pay directly to the applicable government or taxing authority, if requested by Nortel Networks, all such Taxes; provided,
however, that in no event shall Customer be liable for Taxes computed upon the income or gross revenues of Nortel Networks or its subcontractors. 

  

	5.10	Customer shall be responsible for payment of personal property taxes for Products and materials from the date of shipment by Nortel Networks. Customer’s obligations pursuant to

	5.12	If Customer shall claim to be exempt from any Taxes, Customer shall furnish to Nortel Networks a tax exemption certificate from the relevant taxing authority in the form required by
law or otherwise reasonably acceptable to Nortel Networks. If Customer shall claim any such tax exemption and provides Nortel Networks the required tax exemption certificate and Nortel Networks does not collect the Taxes in reliance thereupon,
Customer shall hold Nortel Networks harmless from and against any and all assessments for such Taxes levied on Nortel Networks, including all interest, penalties and late charges upon any such Taxes and the cost of professional consulting fees
incurred by Nortel Networks to settle the applicable tax matter with the relevant tax authorities. 

  

	5.13	If withholding of any Tax is required in respect of any payment by Customer to Nortel Networks hereunder, Customer shall: (i) withhold the appropriate amount from such payment, (ii)
pay such amount to the relevant authorities in accordance with applicable law, and (iii) pay Nortel Networks an additional amount such that the net amount received by Nortel Networks is the amount Nortel Networks would have received in the absence
of such withholding. 

  

	5.14	Customer shall pay all applicable customs fees, import duties, and similar charges directly to the appropriate governmental authorities. Each party agrees to ensure that it is in
good standing and is appropriately registered, including without limitation, with respect to Taxes, in any country, state or other jurisdiction where legally required. 

  

	5.15	Nortel Networks reserves the right to import services or subcontractors when and where necessary to complete services related to this Agreement. To the extent the Local Nortel

Nortel Networks.

reimbursement obligation shall apply only to the extent that the delay was attributable to Customer; and provided, further, that Customer shall promptly reimburse Nortel Networks for any such additional expenses, and Nortel Networks shall
subsequently return to Customer any monies which Customer may have paid in excess once the Parties have reached an agreement on the actual extent of Customer’s reimbursement obligation. 

  

	5.19	Nortel Networks reserves the right to reject an Order at Nortel Networks’ sole discretion, or to withhold shipment of the Products or performance of the Services, or any
portion thereof, if: (i) Customer is in default of its payment obligations hereunder, (ii) Customer is in breach of its obligations under this Agreement, or (iii) Customer falls under any of the situations described in Sections 16.1 (i) through (iv)
hereof, and all relevant dates for completion shall be adjusted accordingly.

office which receives such Orders is located) after delivery thereof if such Orders are in compliance with this Agreement (prices and descriptions) and no additional terms and conditions have been imposed. In the case of Orders for RSSs, (i) payment
of the initial seventy percent (70%) of the purchase price for the Order corresponding to the first calendar quarter of each calendar year shall be made on or before January 15th of such calendar year, together with a letter of credit or other form of payment guaranty consistent with the requirements of Section 5.17 hereof for the

that Customer shall continue to be obligated to comply with all its obligations hereunder. 

  
 6. Warranty 
  

	6.1	Nortel Networks warrants that the Hardware: (i) is free from defects in materials and workmanship, and (ii) substantially conforms to its Specifications. If Hardware does not
function as warranted during the warranty period, Nortel Networks will determine to either: (i) make it do so, or (ii) replace it with substantially equivalent Hardware. 

  

	6.2	Nortel Networks provides the Software on an “AS IS” BASIS WITHOUT WARRANTIES OF ANY KIND. 

  

	6.3	Nortel Networks warrants that Services will be performed in a professional and workmanlike manner. If Services are not performed as warranted and Nortel Networks is notified
in writing by Customer within sixty (60) days of the date of the non-conforming Services, Nortel Networks will re-perform the non-conforming Services. 

  

	6.4	The warranty period for Hardware shall be twelve (12) months from the date of delivery to Customer as per the terms of this Agreement. In the event Nortel Networks determines
that repair or replacement as set forth in this Section 6 cannot be made using commercially reasonable efforts (which determination shall be made within thirty (30) days after Nortel Networks receives written notice from Customer) Nortel Networks
will give Customer a credit equal to the purchase price paid by Customer for the Hardware, provided that Customer has returned such Hardware to Nortel Networks. 

  

	6.5	No warranty is provided for: (i) supply items normally consumed during Product operation; (ii) failures caused by non-Nortel Networks products; (iii) failures caused by a
Product’s inability to operate in conjunction with other Customer hardware or software different from the Third Party Vendor Items provided by Nortel Networks under this Agreement; or (iv) performance failures resulting from improper
installation and maintenance or Customer’s use of unauthorized parts or components. Warranty will be voided by misuse, accident, damage, alteration or modification, failure to maintain proper physical or operating environment, use of
unauthorized parts or components or improper Customer maintenance. The performance by Customer, directly or indirectly, of the installation, engineering, commissioning, network design, support and maintenance of FWA Products by skilled personnel in
accordance with the Nortel Procedures shall not invalidate the warranty provided hereunder. 

  

	6.6	Nortel Networks provides Third Party Vendor Items on an “AS IS” BASIS WITHOUT WARRANTIES OF ANY KIND, unless Nortel Networks specifies otherwise. However, such
Third Party Vendor Items may carry their own warranties and Nortel Networks shall pass through to Customer any such warranties to the extent authorized. Nortel Networks shall provide to Customer the necessary contact information and applicable
documentation, if available, for those third party vendors. Furthermore, Nortel Networks shall provide reasonable 

  

 Page 8 

 Purchase and License Agreement for FWA Equipment 
  

 assistance to Customer so that Customer may avail itself of any such warranties, but only to the
extent such assistance does not cause Nortel Networks to incur any out-of-pocket expenses or material additional costs. 
  

	6.7	Nortel Networks warrants that all Nortel Networks Products supplied hereunder shall have been tested at the factory to ensure that they conform to their Specifications and
that they shall have successfully passed those tests. 

  

	6.8	THESE WARRANTIES AND LIMITATIONS ARE CUSTOMER’S EXCLUSIVE WARRANTIES AND SOLE REMEDIES, AND REPLACE ALL OTHER WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 

  
 7. Services 
  

	7.1	Warranty Services: During the warranty period, Nortel Networks provides warranty Services without charge for Nortel Networks Hardware supplied under this Agreement to correct
Hardware defects or to bring it up to conformance with the Specifications set forth in this Agreement. Warranty Services to be provided by Nortel Networks are further described in Annex “G” hereof. 

  

	7.2	Customer shall notify Nortel Networks prior to returning any Hardware and must reference a return material authorization number issued by Nortel Networks on documentation
accompanying such returned Hardware. When Customer is required to return Hardware to Nortel Networks for warranty service, Customer agrees to ship it prepaid and suitably packaged to a location Nortel Networks designates. Nortel Networks will return
the Hardware to Customer at Nortel Networks’ expense. Nortel Networks is responsible for loss of, or damage to, Hardware while it is: (i) in Nortel Networks’ possession, or (ii) in transit back to Customer. Any exchanged Hardware becomes
Nortel Networks’ property and, subject to Section 8—Title and Risk of Loss, its replacement becomes the Customer’s property. The replacement Hardware may not be new but will be in working order and equivalent to the item exchanged.
The warranty period for the repaired or exchanged Hardware shall be the greater of ninety (90) days from the date of delivery of the Hardware back to Customer, or the remaining Hardware warranty period. Customer agrees to ensure that exchanged
Hardware is free of any legal obligations or restrictions that prevent its exchange and represents that all returned items are genuine and unaltered. Relocation of Products under warranty Services may result in adjustments to the price and response
times. 

  

	7.3	Where applicable, before Nortel Networks provides warranty services, Customer agrees to: (i) follow the problem determination, problem analysis, and warranty services request
procedures that Nortel Networks provides; (ii) secure all program and data contained in Hardware; and (iii) inform Nortel Networks of changes in the Hardware’s location. 

  

	7.4	Post-warranty and other Services to supplement the warranty Services, including advanced shipment of replacement parts, may be available at prices and policies to be negotiated in
good faith and agreed between the Parties. The warranty service terms and exclusions in Section 6 above shall apply to post- and supplemental warranty Services. 

  

	7.5	Services in General: Customer agrees to reasonably cooperate with Nortel Networks in the performance by Nortel Networks of the Services, including, without limitation,
providing Nortel Networks with sufficient and timely access free of charge to facilities, data, information and personnel of Customer in accordance with the then-current Customer policies, and a suitable physical environment meeting Nortel
Networks’ specified requirements to permit the timely delivery and installation of Products and/or performance of Services, including the recovery by Nortel Networks of any tools, diagnostic or test equipment, documentation or other items used
by Nortel Networks in the performance of the Services.

	7.6	In addition, Customer shall be responsible for the accuracy and completeness of all data and information that it provides or causes to be provided to Nortel Networks. In the event
that there are any delays by Customer in fulfilling its responsibilities as stated above, there is a disagreement between the parties as to the cooperation required from Customer, or there are errors or inaccuracies in the information provided,
Nortel Networks shall be entitled to appropriate schedule and pricing adjustments, including storage fees. It is understood and agreed that the Services provided by Nortel Networks may include the advice and recommendations of Nortel Networks, but
all decisions in connection with the implementation of such advice and recommendations shall be the sole responsibility of, and made by, Customer, unless such advice and recommendations are part of consulting services purchased by Customer.

  

	7.7	Service Personnel: Nortel Networks and Customer are each responsible for the supervision, direction, compensation and control of their own employees and subcontractors.
Nortel Networks may subcontract any portion or all of the Services to subcontractors selected by Nortel Networks. Neither Party shall knowingly solicit to hire employees of the other Party with whom it had contact as a result of the performance of
the Services for a period ending twelve (12) months after completion of the Services. Neither Party shall be precluded from conducting generalized searches for employees (and hiring those employees who respond to generalized searches) either through
the use of search firms or advertisements in the media, provided that searches are not specifically targeted to employees providing Services. 

  

	7.8	Intellectual Property Rights: Nortel Networks, on behalf of itself and its subcontractors, reserves all proprietary rights in and to: (i) all methodologies, designs,
engineering details, and other data pertaining to the Services and designs, documentation and other work product prepared by Nortel Networks and delivered to Customer, (ii) all original works, computer programs and updates developed in the course of
providing the Services (except Customer’s developed programs) or as otherwise agreed in writing by the Parties, (iii) discoveries, inventions, patents, know-how and techniques arising out of the Services, and (iv) any and all products
(including software and equipment) developed as a result of the Services. The performance by Nortel Networks of Services shall not be deemed work for hire. Nortel Networks grants to Customer a perpetual, non-exclusive, world-wide, paid up license to
use, copy and modify the designs, documentation and other work product prepared by Nortel Networks and delivered to Customer in the performance of Services solely for Customer’s internal business purposes. It is understood between the Parties
that Nortel Networks will employ its know-how, techniques, concepts, experience and expertise, as well as all other intellectual property, including that to which it reserves its rights hereunder, to perform services for others which are the same as
or similar to the Services. 

  
 8. Title and Risk of Loss

  

	8.1	Title and risk of loss for ordered Hardware and Third Party Hardware shall pass from Nortel Networks to Customer upon its delivery to Customer. 

  
 9. Installation and Commissioning 
  

	9.1	Customer shall perform all installation, commissioning and software loading services with respect to the FWA Products, using skilled personnel and in accordance with the Nortel
Procedures, with the exception of REM software upgrades, which shall be installed by Nortel Networks pursuant to the FWA TAS Agreement.

 10. Confidential Information  
  

	10.1	Confidential information (“Information”) means: (i) Software and Third Party Software; and (ii) all business, technical, marketing and financial information and
data that is clearly marked with a restrictive legend of the disclosing party (“Discloser”). 

  

	10.2	The party receiving Information (“Recipient”) will use the same care and discretion to avoid disclosure, publication or dissemination of Information as it uses with
its own similar information that it does not wish to disclose, publish or disseminate. The Recipient may disclose Information only to: (i) its employees and employees of its parent, subsidiary affiliated companies or subcontractors who have a need
to know for purposes of carrying out this Agreement; and (ii) any other party with the Discloser’s prior written consent. Before disclosure to any of the above parties, the Recipient will have a written agreement with such party sufficient to
require that party to treat Information in accordance with this Agreement. 

  

	10.3	The Recipient may disclose Information to the extent required by law. However, the Recipient must give the Discloser prompt notice and make a reasonable effort to obtain a
protective order. 

  

	10.4	No obligation of confidentiality applies to any Information that the Recipient: (i) already possesses without obligation of confidentiality; (ii) develops independently; or
(iii) rightfully receives without obligations of confidentiality from a third party. No obligation of confidentiality applies to any Information that is, or becomes, publicly available without breach of this Agreement. 

  

	10.5	Each party’s obligations hereunder shall survive for a period of five (5) years after receipt of Information hereunder from the Discloser, except as otherwise mutually
agreed upon by the parties. 

  

	10.6	THE DISCLOSER MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY NATURE WHATSOEVER WITH RESPECT TO ANY INFORMATION FURNISHED TO THE RECIPIENT, INCLUDING, WITHOUT LIMITATION, ANY
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR AGAINST INFRINGEMENT, EXCEPT FOR THOSE SET FORTH IN SECTION 6 HEREOF. 

  

	10.7	The release of any advertising or other publicity relating to this Agreement requires the prior approval of both Parties.  

  
 11. Patents and Copyrights 
  

	11.1	Nortel Networks shall indemnify and hold harmless Customer, its officers, directors, representatives, agents, employees, contractors, subcontractors, subsidiaries and affiliates
against any actual direct loss, damage, liability, cost, expense, action or claim, including reasonable attorneys’ fees, litigation costs and expenses and amounts paid in settlement, subject to the limitations set forth in the following
paragraphs, arising out of or in connection with any infringement or alleged infringement of patents, copyrights, trademarks, trade secrets, or any other intellectual property right of a third party. Therefore, if a third party claims that Nortel
Networks Hardware or Software provided to Customer under this Agreement infringes such third party’s patent or copyright, Nortel Networks will defend Customer against that claim at Nortel Networks’ expense and pay all costs and damages
that a court finally awards or are agreed in settlement, provided that Customer: (a) promptly notifies Nortel Networks in writing of the claim, and (b) allows Nortel Networks to control, and cooperates with Nortel Networks at Nortel Networks’
expense in, the defense and any related settlement negotiations. If such a claim is made or appears likely to be made, Nortel Networks agrees to secure the right for Customer to continue to use the Hardware or Software, or to modify it, or to
replace it with equivalent Hardware or Software. If Nortel Networks determines that none of these options is reasonably available, Customer agrees to return the Hardware or Software to Nortel Networks on Nortel Networks’ written request. Nortel
Networks will then give Customer a credit equal to 

  

 Page 11 

 Purchase and License Agreement for FWA Equipment 
  

	    	the purchase price paid by Customer for the Hardware or Software. Any such claims against the Customer or liability for infringement arising from use of the Hardware or Software
following a request for return by Nortel Networks are the sole responsibility of Customer. This represents Customer’s sole and exclusive remedy regarding any claim of infringement. 

  

	11.2	Nortel Networks has no obligation regarding any claim based on any of the following: (a) anything Customer provides which is incorporated into the Hardware or Software; (b)
compliance by Nortel Networks with the Customer’s specifications, designs or instructions; (c) the amount of revenues or profits earned or other value obtained by the use of a Product by Customer; (d) Customer’s modification of Hardware or
Software (subject to Section 4.4(a) hereof); (e) the combination, operation, or use of Hardware or Software with other products not provided by Nortel Networks as a system, or the combination, operation, or use of Hardware or Software with any
product, data, or apparatus that Nortel Networks did not provide; (f) the Customer’s failure to install or have installed changes, revisions or updates as instructed by Nortel Networks; or (g) infringement by a Third Party Vendor Item alone, as
opposed to its combination with Products Nortel Networks provides to Customer as a system. 

  

	11.3	In case of any infringement caused by any Third Party Vendor Item, Nortel Networks shall reasonably cooperate with Customer and hereby assigns to Customer any of its rights to
request the proper defense and indemnification for such claim to such Third Party Vendor. Nortel Networks shall provide Customer with all necessary contact information and applicable documentation, if available, for those third party vendors.
Furthermore, Nortel Networks shall use its best efforts to provide reasonable assistance to Customer for Customer to be able to obtain from the Third Party Vendor the applicable defense and indemnification for such Third Party Vendor Item
infringement, but only to the extent such assistance does not cause Nortel Networks to incur any out-of-pocket expenses or material additional costs. 

  
 12. Limitation of Liability 
  

	12.1	In no event shall Nortel Networks or its agents or suppliers be liable to Customer for more than the amount of any actual direct damages up to the greater of U.S. $100,000 (or
equivalent in local currency) or the charges for the Product or Services that are the subject of the claim, regardless of the cause and whether arising in contract, tort or otherwise. This limitation will not apply to claims for damages for bodily
injury (including death) and damage to real property and tangible personal property for which Nortel Networks is legally liable and payments as set forth in Section 11 - Patents and Copyrights. 

  

	12.2	IN NO EVENT SHALL NORTEL NETWORKS OR ITS AGENTS OR SUPPLIERS BE LIABLE FOR ANY OF THE FOLLOWING: I) DAMAGES BASED ON ANY THIRD PARTY CLAIM, EXCEPT AS EXPRESSLY PROVIDED FOR HEREIN;
II) LOSS OF, OR DAMAGE TO, CUSTOMER’S RECORDS, FILES OR DATA; OR III) INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS OR LOST SAVINGS), EVEN IF NORTEL NETWORKS IS INFORMED OF THEIR POSSIBILITY.

  
 13. Concessions 
  

	13.1	Customer hereby warrants and represents that it and its affiliates in Mexico have obtained the Concessions which will permit each of them to legally operate all or a portion of the
Products in Mexico. The Parties agree that Nortel Networks shall not deliver or install any Products, perform any Services or accept any Orders hereunder unless Customer or its affiliates (if applicable) have been granted a Concession in Mexico for
the use of such Products. 

  
 14. Changes or Substitution of
Products 
  

	14.1	At any time, Nortel Networks may implement changes to the Products, modify the Products’ designs and Specifications or substitute the Products with ones of similar or
more recent 

  

 Page 12 

 Purchase and License Agreement for FWA Equipment 
  

	    	design. The Parties shall mutually agree on the Price of such changed or substituted Products. Such a change to or substitution of the Products provided under this Agreement shall
be subject to the following requirements: (i) shall not adversely affect the physical or functional interchangeability or the performance Specifications of the Products, except as otherwise agreed in writing by Customer; (ii) the price for
equivalent performance shall be the same or lower than the price agreed hereunder, except as otherwise agreed in writing by Customer; (iii) any change or substitution of the Products shall be functionally equivalent and compatible with the changed
or substituted Product, without the need for any other adaptations; and (iv) shall under no circumstances either reduce or decrease Nortel Networks’ warranty obligations set forth in this Agreement. 

  
 15. Delayed Shipment of the Products or the Performance of the Services 
  

	15.1	If Customer notifies Nortel Networks less than thirty (30) days prior to the scheduled delivery date of the Products (or if the Products have been manufactured per the agreed
upon schedule) that Customer does not wish to take delivery thereof at the scheduled time or that a site is not available to receive such Products, or if Customer fails to take delivery of such Products upon their arrival at the applicable site,
Nortel Networks shall have the right to place the Products in storage and Customer shall bear all costs of demurrage, restocking, warehousing, reloading, transporting, off-loading, and other associated costs incurred by Nortel Networks. All such
costs shall be paid in full within thirty (30) days of Customer’s receipt of Nortel Networks’ commercial invoice therefor. Customer may delay delivery or fail to take delivery of the Products for not more than thirty (30) days. Once such
thirty-day term elapses, Customer shall immediately pay to Nortel Networks the outstanding balance of the purchase price of the Products, if any, and the warranty period for the affected Products shall be deemed to start upon expiration of such
30-day term. 

  

	15.2	If Customer notifies Nortel Networks less than thirty (30) days prior to the scheduled performance date of the Services that Customer does not wish Nortel Networks to perform
such Services at the scheduled time or that the Site is not available for the performance of such Services, Nortel Networks shall have the right to delay the performance of the Services and Customer shall bear all associated and documented out of
pocket travel and expense costs incurred by Nortel Networks. All such costs shall be paid in full within thirty (30) days of Customer’s receipt of Nortel Networks’ commercial invoice therefor. 

  

	15.3	Site facilities and physical specifications of equipment (including shelters, fiber cabling, power, etc.) provided by Customer for use with the Products sold hereunder must
meet Nortel Networks’ installation and environmental Specifications. Any testing required to verify the condition of Site facilities and any required upgrades will be at Customer’s expense. 

  
 16. Termination; Survival 
  

	16.1	Without prejudice to any rights and remedies provided for hereunder, either Party hereto may terminate this Agreement, effective immediately, upon written notice to any other
Party, upon the occurrence of any of the following events or conditions (each, an “Event of Default”): 

  

	 	(i)	the other Party applies for or consents to the appointment of, or the taking of possession by a receiver, custodian, trustee or liquidator of itself or of all or a substantial part
of its property, 

  

	 	(ii)	the other Party makes a general assignment for the benefit of its creditors, 

  

	 	(iii)	the other Party commences a voluntary proceeding under the bankruptcy, insolvency or similar laws relating to relief from creditors generally, 

  

	 	(iv)	the other Party fails to contest in a timely or appropriate manner, or acquiesces in writing to, any petition filed against it in an involuntary proceeding under the

  

 Page 13 

 Purchase and License Agreement for FWA Equipment 
  

	 	    	bankruptcy, insolvency or similar laws relating to relief from creditors generally, or any application for the appointment of a receiver, custodian, trustee, or liquidator of itself
or of all or a substantial part of its property or its liquidation, reorganization, dissolution or winding-up, or 

  

	 	(v)	the other Party materially fails to perform any term or condition under this Agreement or any of its Annexes, which failure continues for a period of thirty (30) days after written
notice has been given to the breaching Party; provided, however, that if any Party exercises its termination rights as provided in this Section 16.1 (v) after any sale of the FWA Business by Nortel Networks, the FWA TAS Agreement,
shall automatically be terminated concurrently therewith; and provided, further, that if any Party exercises its termination rights as provided in this Section 16.1 (v) prior to any sale of the FWA Business by Nortel Networks, the three other
Replacement Agreements shall automatically be terminated concurrently therewith. For the avoidance of doubt, the Parties agree that any failure by Customer to comply with the purchase commitment set forth in Section 19 hereof shall be deemed
material. 

  

	16.2	In addition, and without prejudice to any rights and remedies provided for hereunder, Nortel Networks may terminate all four Replacement Agreements, effective immediately,
upon written notice to the other Party, upon the occurrence of any of the following events or conditions: 

  

	 	(i)	Customer fails to make payment in accordance with the terms and conditions hereof, which failure continues for a period of ten (10) business days (in Mexico) after written notice to
Customer, 

  

	 	(ii)	within eighteen (18) months from the date hereof, the identity of Customer’s business materially changes by sale of its business, transfer of control of its capital stock,
merger or otherwise, unless prior written consent therefor has been obtained from Nortel Networks; or 

  

	 	(iii)	the occurrence of an Event of Default under any one of the Senior Note or the other Replacement Agreements which by the terms of such agreements would allow Nortel Networks to
declare such Senior Note due and payable or to terminate such Replacement Agreement, as the case may be. 

  

	16.3	The respective obligations of each Party pursuant to Sections 1, 4, 5, 6, 7, 10, 11, 12, 16 and 18 hereof, and any other obligations of each Party pursuant to this Agreement that by
their nature would continue beyond the termination, cancellation, or expiration hereof, shall survive such termination, cancellation, or expiration; provided, however, that if Customer fails to make payment in accordance with the terms and
conditions hereof (subject to the cure period provided in Section 16.2 above), the Parties expressly agree that the following Sections hereof shall not survive such termination, cancellation, or expiration: Sections 6 and 7; and provided,
further, that Section 4 hereof shall survive such termination, cancellation, or expiration only to the extent that Customer is not in default of the payment of the applicable Software license fees, if any. 

  
 17. Nortel Procedures 
  

	17.1	“Nortel Procedures” will consist of documents which describe in detail the engineering, installation, commissioning, maintenance, troubleshooting and operation of
Product(s). The Nortel Procedures shall be provided in the English language. Nortel Networks shall provide the Nortel Procedures in Spanish if so published. Nortel Networks shall ship electronic documentation containing the applicable Nortel
Procedures to Customer with the initial delivery of a system release to Customer. During the Term, Nortel Networks shall, at no additional charge to Customer, deliver to Customer, one set of electronic files with updates, revisions and/or
corrections of such Nortel Procedures as they become available. Customer may order additional copies of the Nortel Procedures at Nortel Networks’ then applicable prices. 

  

 Page 14 

 Purchase and License Agreement for FWA Equipment 
  

	    	Customer may use and reproduce the Nortel Procedures in paper format for the purposes of engineering, installing, commissioning, maintaining, troubleshooting and operating the
Products, subject to the limitations regarding Information set forth in Section 10. Reproduction shall include the copyright or similar proprietary notices. Customer is responsible for ensuring proper versions of the Nortel Procedures are printed
and distributed. 

  
 18. General 
  

	18.1	Customer agrees that it will not export Products procured hereunder from Mexico without Nortel Networks’ prior written consent. Nortel Networks reserves the right to
assign any portion of an Order accepted under this Agreement, in whole or in part, provided that such assignment shall be in compliance with the provisions of Section 20 below if such assignment falls under the situation provided for in Section 20
of this Agreement. Customer represents and warrants that it is buying Products and/or Services for its own internal use and not for resale. 

  

	18.2	Customer agrees to comply with all laws applicable to it, including all applicable export and import laws and regulations. In the event that any provision of this Agreement or
portions thereof are held to be invalid or unenforceable, the remainder of this Agreement will remain in full force and effect. 

  

	18.3	The terms and conditions of this Agreement, together with the other three Replacement Agreements and any other agreements contemplated by the Term Sheet entered into between
Customer and Nortel Networks Limited on October 12, 2002, form the complete and exclusive agreement between Customer and Nortel Networks and replaces any prior oral or written communications and agreements regarding the subject matter thereof.

  

	18.4	Any changes to this Agreement must be made by mutual agreement in writing. All Customer’s rights and all of Nortel Networks’ obligations are valid only in Mexico.

  

	18.5	The laws of the State of New York, United States of America govern this Agreement, exclusive of its conflict of laws provisions; and nothing in this Agreement affects any statutory
rights of consumers that cannot be waived or limited by contract. The United Nations Convention on the International Sale of Goods shall not apply. 

  

	18.6	If, within thirty (30) days from the date of any notice of dispute from a Party to any other Party, such Parties are unable to resolve the issue, then either Party may
initiate the binding arbitration to resolve such dispute by written notice to such other Party upon expiration of such thirty (30) day period. Any dispute between the Parties arising in connection with this Agreement shall be exclusively resolved by
arbitration pursuant to the Rules of Conciliation and Arbitration of the International Chamber of Commerce then in force. The arbitration proceedings pursuant to this Section 18(c) shall take place in the English language in the City of
Miami, State of Florida, before a panel of three (3) arbitrators appointed in accordance with the aforementioned rules. The decision of the arbitrators shall be final and binding upon the Parties and their respective successors and assigns. The
decision and award rendered by the arbitrators may be entered in any court of competent jurisdiction and any such court may order the enforcement of such award against the Parties and their respective successors and assigns.

  

	18.7	EACH PARTY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF, OR RELATING TO, THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREIN, INCLUDING ANY ORDER ISSUED AND ACCEPTED HEREUNDER.

the performance of any other obligation hereunder by any party is prevented, delayed, interfered with, or interrupted by reason of a Force Majeure Event, such prevention, delay, interference, or interruption shall be deemed not to be a default
pursuant to this Agreement and the time or times for such performance or supply hereunder shall be extended by the period or periods same is so prevented, delayed, interfered with, or interrupted. The foregoing shall apply even though any such cause
exists or is foreseeable as of the date hereof. Neither Party shall be required to change its usual business practices or methods or to assume or incur other than its usual costs or expenses in order to mitigate, avoid, or eliminate any Force
Majeure Event or to reduce the period of any resulting delay. Each Party shall notify the other Parties of any delay or failure excused by this Section 18(f) and shall specify the revised performance date as soon as practicable. Nothing contained in

 19. Purchase Commitment 
  

	19.1	Customer hereby irrevocably agrees to purchase from Nortel Networks the minimum annual amounts of Products as further described in Annex H hereof. 

  
 20. Assignment; Right of First Refusal 
  

	20.1	Each Party agrees not to assign or otherwise transfer this Agreement or its rights under it, or delegate its obligations, without the other Party’s prior written
consent, and any attempt to do so is void. Notwithstanding the foregoing, Nortel Networks may assign or otherwise transfer this Agreement or its rights under it, or delegate its obligations, to any of its affiliates. Nortel Networks may also assign
or otherwise transfer this Agreement or its rights under it, or delegate its obligations, to any purchaser of the FWA Business without the Customer’s prior written consent; provided that: 

  

	 	(i)	Nortel Networks shall provide to Customer the soliciting or offering material used in connection with any contemplated sale of the FWA Business (the “FWA
Information”) at the same time any such FWA Information is provided to any third party potential purchaser (the “Potential Purchasers”), subject to execution by the Parties of a non-disclosure agreement in a form
and substance reasonably satisfactory to Nortel Networks, but no less restrictive on Customer than the non-disclosure agreement executed with the Potential Purchasers; and provided, however, that Nortel Networks may not offer, solicit
interest in or sell the FWA Business to any company which is a direct competitor of Customer or does not have the necessary resources (human and/or technical), at Nortel Networks’ reasonable judgment, to manufacture the Products and/or to
provide the technical support required by Customer, including without limitation, Teléfonos de México, S.A. de C.V. or any of its affiliates (the “Restricted Companies”); 

  

	 	(ii)	Nortel Networks hereby grants to Customer a right of first refusal (“RFR”) with respect to any offer received by Nortel Networks from any third party which Nortel
Networks proposes to accept (including any revised offers), allowing Customer to purchase the FWA Business on terms not less favorable than such offer, subject to Customer having made, within fourteen (14) days after Nortel Networks shall have
delivered written notice to Customer of such offer or revised offer (the “Vendor’s Notice”), a single deposit of US$4,500,000.00 (four million five hundred thousand United States dollars) (the “Deposit”)
into an interest bearing escrow account. Once Nortel Networks has received the Deposit, Customer shall have the right to perform a due diligence investigation of the FWA Business, and Nortel Networks shall be obligated to promptly provide all the
information and access that Customer reasonably requires for the evaluation of the FWA Business; and 

  

	 	(iii)	in the event of any such sale to a purchaser other than Customer, such new vendor shall assume all of Nortel Networks’ obligations under this Agreement.

  

	20.2	If Customer exercises its RFR, Nortel Networks and Customer shall have sixty (60) days from payment of the Deposit to negotiate in good faith and enter into a purchase
agreement pursuant to which Nortel Networks will sell the FWA Business to Customer, unless a longer period of time is stated in the offer received from the Potential Purchaser, in which case such longer period shall prevail (the “Offer
Period”). If the Parties have entered into such an 

  

 Page 17 

 Purchase and License Agreement for FWA Equipment 
  

	    	agreement by the end of the Offer Period, the Deposit shall be credited towards the purchase price of the FWA Business. If the Parties have not entered into such an agreement by the
end of the Offer Period, Customer shall forfeit in favor of Nortel Networks the Deposit, and Nortel Networks shall have the right to sell the FWA Business to any Potential Purchaser other than a Restricted Company, subject to the terms and
conditions of Section 20.3 below; provided, however, that if the terms of the proposed sale are more favorable to such Potential Purchaser than the best offer (from Nortel Networks’ perspective) presented by Customer to Nortel Networks
during the Offer Period, then the RFR shall again apply to such sale, but Customer shall not be obligated to provide any additional Deposit. 

  

	20.3	If Customer shall decline in any instance to exercise its RFR or the Parties fail to enter into the purchase agreement as described in Section 20.2, Nortel Networks shall
have the right for a period of one year from the date of such declination or failure, to sell the FWA Business to a Potential Purchaser (except if such Potential Purchaser is a Restricted Company) without prior notice to Customer, on terms which are
not more beneficial to such Potential Purchaser than those set forth in Vendor’s Notice. If the foregoing conditions are not met, the RFR shall again apply to such sale; provided, however, that the 60-day term provided in Section 20.2
above shall be reduced to thirty (30) days and Customer shall not be obligated to provide any additional Deposit. 

  
 The Parties hereto have executed this Purchase and License Agreement for FWA Equipment as of February 14, 2003 and it shall become effective on the Closing Date.

 Annex D 
  
 Product Specifications 
  
 PLA FWA Contract 
 1. Scope

  

	1.1	This section defines the essential performance characteristics of the Nortel Networks Internet Fixed Wireless Access system (Internet FWA). The scope of the section is confined to
the airside equipment that supports wireless transmission in the local loop, i.e. that part of the system from the Base-station network interface to the subscriber premises terminal interface (telephone socket), together with associated network
management operations systems in the element management layer. The specifications for the switch, service gateway and other associated backhaul equipment are therefore specifically excluded from this section. 

  
 2.1 General description 
  
 2.1.1 Intentionally Left in Blank 
  
 2.1.1.1 Purpose of Internet FWA 
  
 The Internet FWA system allows telecommunications operators to construct high quality
telephone access networks between customers’ premises and local exchanges. The system uses cellular point to multi-point wireless technology as a replacement for traditional copper-based local loops. A major advantage of FWA technology is that
it allows operators to create new access networks quickly and with minimum capital investment. 
  
 Each terminal in the Internet FWA system is capable of delivering PSTN circuit-switched services through two standard analogue telephone lines. In addition to the PSTN services, a packet-mode service may be used to
deliver ‘always-on’ connections between one or more Internet Service Providers (ISPs) and the computer equipment of subscribers. 
  
 The Internet FWA system provides a frequency division duplex radio link to a subscriber transceiver system and operates in the 3.4 to 3.6 GHz band. The air interface
utilizes time division multiplex on the downlink and time division multiple access on the uplink. The system comprises a network of Radio Base-stations (RBS) arranged on a cellular plan and these are connected to the PSTN or to the public Internet
by a conventional back-haul network. Each base-station consists of one or more Integrated Transceiver Systems (ITSs). 
  
 2.1.2 Sub-systems 
  
 The Internet FWA system contains two Network elements (NEs): 
  
 Remote Service System (RSS) 
 Radio Base Station (RBS) 
  

 Page 30 

 Purchase and License Agreement for FWA Equipment 
  

 The Internet FWA system contains three Operations systems (OSs): 
  
 Radio Element Manager (REM) 
 RSS Installation System (RIS) 
 Field Engineering Terminal (FET) 
  
 The Remote
Service System (RSS) 
  
 This system provides the subscriber with two
independent analogue exchange lines and optionally a packet data service interface. The system consists of the RSS Terminal Unit (RTU), an RSS Power and Connection unit (RPCU) and an RSS Data Adapter (RDA). 
  
 The RTU is mounted externally to the subscriber premises and contains a directional antenna,
radio electronics and the two analogue line interfaces to carry PSTN services. The unit is powered from the RPCU indoor unit that plugs into the subscribers mains supply. A ‘drop cable’ connects the RTU to the RPCU. The RPCU contains two
sets of telephone sockets for connection to the subscriber’s telephone equipment. In order to provide the optional packet data service, an RDA is supplied along with a special version of the RTU that contains the required data interface. The
packet data service makes use of the HPNA standard to multiplex the data onto ‘line 0’ of the telephone wires. The RDA connects to the subscriber’s personal computer. 
  
 The Integrated Transceiver System (ITS) 
  
 One or more ITSs form the basis of the radio base-station and have been designed to serve an area of up to 5km radius in a typical urban environment and up to 20km in a
rural environment. 
  
 Voice band circuits from the ITS are connected to the
switch by means of E1 links running a V5.2 protocol. The packet data service is also routed over E1 links to the service gateway using L2TP (layer 2 tunnel protocol). The ITS can route any slot from the ‘circuit’ E1s to any slot on the
airside interface. 
  
 In principle, an ITS can be provisioned as a 3, 6, 9, 12,
15 or 18 bearer configuration. RBS configurations specifically supported by installation and maintenance processes provide tri-sectored configurations with 18 or 271 RF carriers, or a tri/hex-sectored RBS with 48 RF carriers. The 27-carrier configurations require the use of two ITSs, and the 48-carrier configuration requires the use of three ITSs. The 48 bearer
base-station is designed to provide coverage in two ‘RF layers’, the first layer allowing a frequency re-use of one to be employed whilst a more conservative frequency plan is used in the other layer. Service to the individual RSS can be
switched between these two layers depending on the interference environment experienced at that RSS. 
  
 Radio Element Manager (REM) 
  
 The Radio
Element Manger (REM) is a high performance, high capacity management system and is used to perform the Operation, Administration, Maintenance and Provisioning (OAM&P) procedures for the Internet FWA network. One REM can manage up to 200 ITSs and
150,000lines. The REM is primarily composed of a server platform, a client platform, additional user PCs and a Network Communications Server. Their respective purposes are described below. The REM supports a total of 4 expert and 4 standard user
sessions. 
  
 The REM server performs all provisioning related, object-related,
event and alarm related processing, together with some of the GUI processing. Further, the server stores all object, event and alarm related data and state. As such, the majority of REM software executes on the server. The server also interfaces
directly to a customer’s High Level Management System (HLMS) for subscriber provisioning. 

	1	In the Axtel application, the 27 bearer base-stations generally provide only 26 bearers due to limited availability of RF channels. 

  

 Page 31 

 Purchase and License Agreement for FWA Equipment 
  

 The REM Client primarily acts as the host platform for the additional user GUI screens. It provides some of the GUI
processing, and acts as a platform on which additional user scripts run. 
  
 PCs
running Exceed software connect with the REM client to allow access for additional users. 
  
 The Network Communication Server (NCS) is an integrated terminal server and modem unit, which provides a connectivity solution from the REM to its network of ITSs. It also provides connectivity to the Remote
Maintenance Terminal that is used during the subscriber hardware installation. 
  
 Field engineering terminal (FET) 
  
 The installing engineer will
use this equipment during installation and commissioning of Base-station equipment. The FET application runs on a PC platform using a LINUX operating system. The FET is intended to connect locally into an ITS and allows control of the ITS as well as
access to status information. Each FET requires a license key to enable operation and these are available from Nortel Networks. 
  
 RSS Installation system (RIS) 
  
 The installing engineer will use this equipment to control the RSS during installation, to aid antenna alignment to the Base Station, to measure the performance of the RF
link and to enable the connection. The primary component of the RIS is the Remote Maintenance Terminal (RMT). 
  
 2.1.3 External interfaces 
  
 The physical layer external interfaces of the Internet FWA system are: 
  
 Analogue line interface at the RSS 
 Packet data interface at the RSS 
 A.C. power interface at the RSS 
 PCM (E1) interface at the RBS 
 Packet data (E1) interface at the RBS 
 D.C. power interface at the RBS 
 External alarm interface at the RBS 
 Analogue line interface at the RIS. This
is used to connect the RMT to the REM to download provisioning data. 
 Analogue line interface at the REM 
 Ethernet interface at the REM. This is used to connect the REM to higher-layer operations systems.

 2.3 Radio system 
  
 2.3.1 General description of the air interface 
  

	2.3.1.1	Physical layer 

  
 The physical layer of the Internet FWA air interface uses digital time division multiplex/time division multiple access (TDM/TDMA) with a 10-slot frame structure. Uplink and downlink carriers are paired, and separated
by a fixed duplex spacing of 99.84MHz. A TDM/TDMA channel (i.e. one time-slot one on one RF carrier) is known as a physical channel. In the maximum configuration, one ITS provides 18 pairs of RF carriers, and 180 physical channels. 
  
 The uplink carriers are contained within the frequency band 3425 MHz to 3450 MHz, and the
downlink carriers are contained within the frequency band 3525 MHz to 3550 MHz. 
  
 The modulation scheme for both the uplink and downlink direction is pi/4 shifted differential quadrature phase shift keying (p/4DQPSK) with a
nominal symbol rate of [*] symbols/s. The gross data rate [*]/s per carrier. 
  
 Reserved channels are used to allow contention access by terminals. These access channels are not available for carrying subscribers’ voice or data traffic. 
  

	2.3.1.2	Channel plan 

  
 The Internet FWA system operates over 78 RF channels, with a nominal channel spacing of 307.2 kHz. The lowest uplink channel (Ch. 2) has a nominal centre frequency of 3425.8944 MHz. The highest downlink channel (Ch.
79) has a nominal centre frequency of 3549.3888 MHz. The fixed duplex spacing is equivalent to 325 times the channel spacing. 
  

 Page 34 

 Purchase and License Agreement for FWA Equipment 
  

	2.3.1.3	MAC layer for PSTN traffic 

  
 One physical channel is capable of carrying a single 32 kbit/s ADPCM circuit-switched connection, or one half of a 64 kbit/s PCM circuit-switched connection. 
  

	2.3.1.4	MAC layer for the Packet data service 

  
 Physical channels can be allocated in groups of six to carry packet-mode traffic. One group of six physical channels is described as a packet channel. 
  
 2.3.2 RF performance of the ITS equipment 
  

	2.3.2.1	Maximum transmit power 

  
 The maximum transmit power from the ITS is not less than 28 dBm for each carrier, measured at the antenna port of the TMU. 
  

	2.3.2.2	Transmitter implementation loss 

  
 The transmitted signal from the ITS is a close approximation to an ideal p/4DQPSK signal. The additional carrier to noise margin required to demodulate the practical transmitted signal, compared to an ideal signal is less than 1 dB. 
  

	2.3.2.3	Spectrum due to modulation 

  
 The spectrum due to modulation at the output of the ITS is as follows: 
  

			
	 Channel

	 	 Mean power (dBc)

	 N
	 	[*]
		
	 N ± 1
	 	[*]
		
	 N ± 2
	 	[*]
		
	 N ± 3
	 	[*]
		
	 Any other channel
	 	[*]

  
 The mean power is measured using an
ideal receiver with root-raised-cosine filtering with transition factor (a) = 0.4, and with the receiver tuned to the centre of the appropriate adjacent
channel. 
  

	2.3.2.4	Minimum receiver sensitivity 

  
 The receiver sensitivity for the ITS is not greater than [*] measured at the antenna port of the TMU, for a bit error ratio (BER) of 10-3 before forward error correction. This measurement assumes an ideal transmitter. 
  

 Page 35 

 Purchase and License Agreement for FWA Equipment 
  

	2.3.2.5	Receiver selectivity 

  
 The ITS receiver selectivity is specified in terms of the level of interfering signal consistent with a bit error ratio (BER) for the wanted signal of less than 10–3 before FEC. The interfering signal is assumed to be from a signal source with the ideal characteristics of the Internet FWA radio system, centered on the
applicable adjacent channel. The wanted signal is assumed to be from a similar ideal source and set at a level 3 dB greater than the level required for BER = 10–3 in the absence of interference. The carrier to interference levels are as follows: 
  

			
	 Channel

	 	 Carrier/Interference ratio for BER = 10–3

	 N
	 	[*]
		
	 N ± 1
	 	[*]
		
	 N ± 2
	 	[*]
		
	 Any other channel
	 	[*]

  
 2.3.3 RF performance
of the RSS equipment 
  

	2.3.3.1	Maximum transmit power 

  
 The maximum transmit power from the RSS is not less than [*]EIRP in RF channels 8 to 73 inclusive, and not less than [*] EIRP in the remaining channels. This transmit power specification applies to the complete RTU
including the antenna. 
  

	2.3.3.2	Transmitter implementation loss 

  
 The transmitted signal from the RSS is a close approximation to an ideal p/4DQPSK signal. The additional carrier to noise margin required to demodulate the practical transmitted signal, compared to an ideal signal is less than 1 dB. 
  

	2.3.3.3	Spectrum due to modulation 

  
 The spectrum due to modulation at the output of the RSS is as follows: 
  

			
	 Channel

	 	 Mean power (dBc)

	 N
	 	[*]
		
	 N ± 1
	 	[*]
		
	 N ± 2
	 	[*]
		
	 N ± 3
	 	[*]
		
	 Any other channel
	 	[*]

  

 Page 36 

 Purchase and License Agreement for FWA Equipment 
  

 The mean power is measured using an ideal receiver with root-raised-cosine filtering with transition factor
(a) = 0.4, and with the receiver tuned to the centre of the appropriate adjacent channel. The measured power is averaged over duration of the time-slot
containing the uplink transmission. 
  

	2.3.3.4	Minimum receiver sensitivity 

  
 The receiver sensitivity for the RSS is not greater than [*] in RF channels 8 to 73 inclusive, and not greater than [*] in the remaining channels. The received signal is
measured at the connector of the RTU antenna, for a bit error ratio (BER) of 10-3 before forward error correction.
This measurement assumes an ideal transmitter. 
  

	2.3.3.5	Receiver selectivity 

  
 The RSS receiver selectivity is specified in terms of the level of interfering signal consistent with a bit error ratio (BER) for the wanted signal of less than 10–3 before FEC. The interfering signal is assumed to be from a signal source with the ideal characteristics of the Internet FWA radio system, centered on the
applicable adjacent channel. The wanted signal is assumed to be from a similar ideal source and set at a level 3 dB greater than the level required for BER = 10–3 in the absence of interference. The carrier to interference levels are as follows: 
  

			
	 Channel

	 	 Carrier/Interference ratio for BER = 10–3

	 N
	 	[*]
		
	 N ± 1
	 	[*]
		
	 N ± 2
	 	[*]
		
	 N ± 3
	 	[*]
		
	 N ± 4
	 	[*]
		
	 N ± 5
	 	[*]
		
	 Any other channel
	 	Blocking specification applies

	2.3.3.6	RSS receiver dynamic range 

  
 The dynamic range of the RSS receiver is from the limit of sensitivity to –20 dBm, measured at the antenna connector of the RTU. Over this dynamic range the BER of the received signal (measured before forward
error correction) is not greater than 10-3. 
  

	2.3.3.7	RSS antenna gain 

  
 The gain of the RSS antenna is between [*] at the peak of the response. The nominal beamwidth is [*] degrees (i.e. ± [*]). The rejection of cross-polar signals in the main antenna response is not less than [*]
compared to a co-polar signal of identical level. The maximum level of side-lobe responses is [*], and this limit applies at azimuth angles from [*] degrees to [*] degrees with respect to the peak response. 
  
 2.3.4 Automatic power control 
  
 To minimise interference in the network, the system incorporates automatic uplink RF power
control whereby the ITS attempts to maintain a constant received signal strength (RSSI) of [*] for each active call or packet connection. If the RSSI strays from this target, the ITS will send a message to the appropriate RSS requesting an
appropriate modification to the uplink RF power. The ITS normally integrates the RSSI over a [*] period before deciding whether an adjustment is required although there is a faster attack period at the start of a call or packet connection. At the
end of a call or connection, the RSS calculates a new RF power that will be used to initiate the next call or connection on the same RF channel. 
  
 To maintain an appropriate initial uplink RF power level during extended periods of call inactivity, network test calls are automatically scheduled to each RSS on each of
its operating channels. Just as is the case for normal calls, the uplink RF power is adjusted appropriately at the end of a network test call. The scheduling period is normally set to 23 hours. 
  
 2.3.5 Combining diversity 
  
 In ITS configurations with 2 or more TMUs per sector, the system is configured to execute
two-path maximum ratio combining in the uplink. The implementation of this feature delivers the theoretical benefit of maximum ratio combining with less than 1 dB implementation loss. 
  
 The TMU receiver is wideband and covers all of the uplink spectrum. This means that the IF signals from 2 TMUs in the same sector differ
only by virtue of being received from 2 physically separated antennas. The two I.F signals are fed to separate arms of each receiver pair of every TBM in the sector. The TBM hosts three such receiver pairs where each pair is configured to an
appropriate channel. The maximum ratio combining algorithm is executed independently on each receiver pair. 
  
 2.3.6 Dynamic carrier list management 
  
 Dynamic carrier list management feature allows each RSS to modify the classification of individual RF carriers in response to periodic measurements of the received (downlink) signal. Each RSS notifies the ITS of
changes in carrier classification, allowing the ITS to allocate channels with a priority reflecting the recent quality of downlink carriers. This feature has proven to be effective in combating the effects of static frequency-selective fading, and
minimizing the impact of downlink radio interference from nearby RBSs in the same network. This feature is extremely valuable in networks where tri-sector and tri/hex-sector RBSs are built in adjacent or nearby cells.

 2.4 Equipment configurations 
  
 2.4.1 RBS configurations 
  
 RBS configurations that can be constructed using SR14 consist of one, two or three ITSs. The table below lists the configurations that can be used.

	 	  	6.6.4	  	5	  	0, 2	  	 
	 	  	6.6.4	  	5	  	0, 2	  	 

  
 The column ‘ITS sector
organization’ denotes the number of RF carriers than are enabled in each sector. No relationship is implied between the position of the elements of this list and the numbering of ITS sectors; thus a sector organization of 6.6.5 applies equally
to configurations where the five-carrier sector is ITS sector 1, 2 or 3. 
  

 Page 39 

 Purchase and License Agreement for FWA Equipment 
  

 The tri/hex configuration is described as 6.6.4. The six-carrier sectors are associated with the hex-sectored
antennas, and the four-carrier sector is associated with the tri-sectored antennas. By default, the tri-sector is ITS sector 1. 
  
 The following rules apply: 
  
 Where PDS is required at an ITS, two TPM-PDs must be fitted. 
 Each TPM requires one E1 connection between the ITS and the
local exchange. 
 Each TPM-PD requires one E1 connection between the ITS and the service gateway. 
  
 Some of the base station configurations make use of more than one ITS. PDS can be enabled or
disabled on a ‘per-ITS’ basis, and so it is possible to create a multi-ITS configuration where only one or two of the ITSs has PDS enabled. 
  
 2.4.2 PSTN traffic capacity 
  
 The PSTN traffic capacity of the supported RBS configurations is detailed in the table below. Note these figures apply where PDS is not provided; the PSTN capacity of an
ITS with PDS is necessarily lower. 
  

					
	 	  	Reference capacity (E)

	 Base station configuration

	  	Soft sector = 0%

	 	Soft sector = 10%

	 18-carrier, tri-sector, Type I
	  	[*]	 	[*]
	 26-carrier, tri-sector, Type III & IV
	  	[*]	 	[*]
	 27-carrier, tri-sector, Type II
	  	[*]	 	[*]
	 48-carrier, tri/hex-sector
	  	[*]	 	[*]

  
 The reference capacity is defined as
the capacity at 1% probability of blocking for long ADPCM calls, with the optimum distribution of traffic loading between ITS sectors. 
  
 The soft-sector capacity assumes that 10% of the traffic loading arises from subscribers in the overlap regions between sectors, and that the soft-sectored load is
distributed evenly between three overlap regions (3.3% of the total load in each overlap). In 26-carrier RBSs of type III and IV, and 27-carrier RBSs of type II, there is only one overlap region where a benefit is derived from soft sectoring; in
these cases, the capacity gain is relatively small. In the tri/hex-sectored ITS, soft-sectoring is not enabled between hex-sectors. 
  
 One ITS with V5.2 interface can support a maximum of 2048 PSTN lines, and a maximum of 2048 RSSs.

 2.4.3 Packet data traffic capacity 
  

	2.4.3.1	Number of packet channels at an ITS 

  
 Packet channels at an ITS can be configured subject to the following rules: 
  
 Packet data can be supported by ITSs with sector arrangement 6.6.6, 6.6.5, 8, 9, 9.8, 9.9, 6.6.4 (tri/hex) 
 All packet channels consist of 6 physical channel pairs 
 An ITS that supports PDS has two TPM-PDs 
 One TPM-PD may support zero to four packet channels inclusive 
 One ITS
supports a maximum of 36 physical channels (i.e. six packet channels) 
 The largest packet partition allowed in one sector is three packet channels

 In bi-sector or tri-sector ITSs, if the ITS provides PDS then each sector must have at least one packet channel 
 In a tri-sector ITS, the sum of the number of packet channels in the smallest two packet partitions must not exceed four. This ensures that sectors will not be split
across TPM-PDs. 
  

	2.4.3.2	Number of simultaneous PPP and MAC connections 

  
 The packet data service supports a maximum of: 
  
 700 packet data subscribers per ITS 
 700 simultaneous PPP connections per ITS

 25 simultaneous active MAC connections per packet channel 
 60
simultaneous active MAC connections per TPM-PD 
 110 simultaneous active MAC connections per ITS 
  

	2.4.3.3	Traffic capacity of a packet channel 

  
 Each packet channel (consisting of six physical channels) provides a shared channel with an aggregate capacity for users’ packet data traffic of not less than 192
kbps in the downlink direction, and not less than 84 kbps in the uplink direction. PPP, TCP and IP headers applied at the users’ computers are assumed to form part of the useful throughput. 
  

	2.4.3.4	Peak throughput for a single PDS user 

  
 The peak throughput for a single user is approximately 96 kbps in the downlink direction (using the USB interface) and approximately 92 kbps in the downlink direction
(using the RS-232 interface). The peak throughput for a single user is approximately 42 kbps in the uplink direction. 
  
 Note that these are peak figures, and apply when the user has exclusive use of three physical channels. In normal operation, the packet channel capacity is shared between
a number of users, and mean throughput figures for individual users will be lower than these peak values. The operator must ensure that sufficient packet channels are configured to offer reasonable quality of service to packet data subscribers.

  

	2.4.3.5	Reduction in PSTN capacity 

  
 The remaining PSTN traffic capacity at an RBS with packet data service is defined in the following table. These figures assume that 10% of the offered traffic is from soft-sectored terminals.

 2.5 External interfaces 
  
 2.5.1 ITS to transmission system 
  
 The interface between the ITS and the transmission system is defined by ITU-T 
 G.703 11/2001, ‘Physical/electrical characteristics of hierarchical digital interfaces’. Only the interface at 2048 kbit/s is supported in Internet FWA. 
  
 As an additional requirement, Internet FWA requires that the long-term frequency accuracy of
the E1 signal from the transmission system is better than 10–7 (0.1 ppm). Transmission equipment does not
normally re-time digital traffic, and so this frequency accuracy is usually dependent on correct configuration of the local exchange (for PSTN connections) or the packet data network. 
  
 Internet FWA complies with ITU-T G.823, ‘The control of jitter and wander within digital networks which are based on the 2048 kbit/s
hierarchy’. 
  
 2.5.2 ITS to local exchange 

 
 The framing structure of the signal between the ITS and the local exchange is defined by
ITU-T G.704 10/1998, ‘Synchronous frame structures used at 1544, 6312, 2048, 8448 and 44 736 kbit/s hierarchical levels’, and ITU-T G.706 04/1991, ‘Frame alignment and cyclic redundancy check (CRC) procedures relating to basic frame
structures defined in Recommendation G.704’. 
  
 The voice coding for
circuit-switched traffic complies with ITU-T G.711 11/1988, ‘Pulse code modulation (PCM) of voice frequencies’. 
  
 Signaling between the ITS and the local exchange uses the V5.2 protocol, defined in the ETSI V5.1 Specification ETS 300 324-1, V 1.2.2, ‘V-Interfaces at the digital
local exchange (LE) - V5.1-Interface (based on 2048 kbit/s) for the support of access network (AN)’, and ETSI V5.2 Specification ETS 300 347-1, V 2.1.2, ‘V-interfaces at the digital local exchange (LE) - V5.2 interface (based on 2048
kbit/s) for the support of access network (AN)’. Only requirements for PSTN services apply to Internet FWA. 
  
 2.5.3 ITS to packet data network 
  
 Internet FWA requires that the E1 signal from the packet data network must comply with the framing structure defined in ITU-T G.704 (see above for a detailed reference). Time-slot zero contains a frame synchronization
signal, and the remaining 31 time-slots are joined together to provide a connection with an aggregate capacity of 1984 kbit/s. 
  

 Page 42 

 Purchase and License Agreement for FWA Equipment 
  

 The layer-2 tunnel between the ITS and the packet data network uses a protocol stack consisting of the point-to-point
protocol (PPP), Internet protocol (IP), user datagram protocol (UDP) and the layer-2 tunneling protocol (L2TP). These protocols are defined as follows: 
  
 PPP: Internet engineering task force (IETF) STD 51, ‘The point to point protocol’ 
 IP: IETF RFC 791, ‘Internet protocol’ 
 UDP: IETF RFC 768, ‘User datagram protocol’ 
 L2TP: IETF RFC 2661, ‘Layer two tunnelling protocol (L2TP)’ 
  
 2.5.4 RDA to PC 
  
 The RDA provides a choice of two different serial data standards at the PC-RDA interface: 
  
 Asynchronous serial interface (commonly known as RS-232) as defined in ANSI/TIA/EIA-232-F-1997, Interface Between Data Terminal Equipment
and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, and 
 Universal Serial Bus (USB), using the ‘full-speed’ option,
as defined in Universal Serial Bus specification, Rev. 1.1 and USB class definitions for communications devices, Rev. 1.0. 
  
 2.6 Additional Specifications 
  
 In addition to the Product’s Specifications set forth in this Annex D, the Parties agree to include as part of this Annex D the Product’s
Specifications that will be set forth in the Compact Discs to be named as: (i) Internet Fixed Wireless Access, MR 14.0.3 “Customer Documentation Suite” and (ii) Internet Fixed Wireless Access, Maintenance Release MR 14.0.3 System Line Up
that will be delivered with MR14.03 in February 2003.

 ANNEX G - WARRANTY SERVICES 
  

	1.0	SERVICES SUMMARY 

  
 For this 1-year Warranty, Nortel Networks will: 
  

	 	•	Provide Remote Technical Assistance to assist Axtel in the diagnosis of hardware failures during the warranty period for all Nortel Networks’ Hardware supplied by Nortel
Networks under this Agreement. 

  

	 	•	Repair or replace a defective Field Replaceable Unit (FRU). Target times for repair/replacement are within 60 days following receipt of the defective FRU. 

 
 Note: AXTEL will maintain its own stock of spares at
levels sufficient to cover requirements within timeframes consistent with AXTEL quality of service objectives. 
  
 Nortel Networks will register and manage requests for Remote Technical Assistance and for FRU replacement during normal business days and hours in the
location where the service is being performed. 
  
 Here follows a description of the warranty services to be provided by Nortel Networks: 
  

	1.1	Technical Assistance Service during Warranty Period 

  

	1.1.1	Technical Assistance Service Deliverables 

  

	 	•	Provide Remote Technical Assistance to assist Axtel in the diagnosis of hardware failures during the warranty period. 

  
 To provide Technical Assistance, Nortel Networks technicians and engineers
will provide support primarily by remote means. In a collaborative effort with Axtel’s technical staff, these personnel will attempt to diagnose and resolve issues related to the hardware supplied by Nortel Networks as explained in this service
description. 
  
 Where telephone support, remote diagnosis, and
all other means of restoring product operation have failed, Nortel Networks, upon Axtel’s request, and if Nortel Networks determines that on-site support is necessary and appropriate, will dispatch a trained and qualified technical expert to
Axtel’s premises to facilitate further diagnosis. 
  

	 	–	Notwithstanding Nortel Networks’ determination that on-site support is not necessary, Axtel will nevertheless have the right to require on site support from Nortel Networks,
provided that such on site support required by Axtel shall be at Axtel’s cost unless it is agreed that it was necessary for such support to be provided on site. 

	1.1.2	Axtel Responsibilities for Technical Assistance Service 

  
 For Remote Technical Assistance Axtel will be required to: 
  

	 	•	Confirm that the products have been installed & commissioned and are used and maintained by knowledgeable and skilled people using Nortel Procedures. 

 

	 	•	Replace hardware components during diagnosis or as remedial actions. 

  

	 	•	Generate performance/availability reports and associated trend analysis. 

  

	 	•	Gather data in a timely manner in support of Nortel Networks’ diagnostic process when reasonably within the technical competency of AXtel. 

  

	 	•	Identify issues requiring hardware replacement 

  

	 	•	If applicable, use all reasonable efforts to maintain hardware and software at the release or update level for supported hardware and software. This maintenance will need to be in
accordance with policies and procedures published by Nortel Networks. Axtel will maintain software levels at the then-current or immediately prior Software Release level. 

  
 Perform software upgrades and/or patch applications 
  

	 	•	Provide connectivity in a timely manner to the product(s) for Nortel Networks to establish a data link for use by Nortel Networks technical support group in order to conduct remote
diagnosis and maintenance 

  
 Note: Axtel and Nortel Networks technical personnel will agree on the appropriate type of data link based on network equipment and configuration as well as the appropriate security measures to prevent unauthorized access.
Axtel will be solely responsible for security of the network. Nortel Networks will not connect to Axtel’s network without prior authorization and such connection will be solely to provide technical support. 
  

	 	•	Excuse Nortel Networks from fault resolution for a period equal to such failure or delay, should Axtel fail or cause delay in providing connectivity 

  

	 	•	Designate and make available competent personnel to aid in problem diagnosis and provide electronic access to the affected product(s) to aid in problem investigation and resolution
for all incidents. Axtel personnel should be available to work together with Nortel Networks technical expert during all the process. 

  

	 	•	Axtel should provide their internal escalation process in order to inform all the contacts to Nortel Networks. 

  

	 	•	Maintain a support agreement(s) with the third-party supplier(s) for such product(s), as Axtel sees fit. 

	 	•	Axtel’s in-house structure that performs first-line support will need to exhaust internal troubleshooting processes. First-level Operations, Administration, and Maintenance
(OA&M) functions may include, but are not limited to:  

  

	 	–	Performing day-to-day maintenance and network operations 

  

	 	–	Monitoring network and system alarms 

  

	 	–	Performing diagnosis in accordance with instructions provided by Nortel Networks and carrying out initial remedial actions, including remote diagnosis 

  

	 	–	Operating and controlling Axtel’s internal help desk for logging and tracking fault inquiries, prioritizing events, and escalating, as required, to the Nortel Networks
technical support group 

  

	 	–	Providing local time templates and historical actions performed on each event as reference information to the Nortel Networks technical support group (NTS).

  

	1.1.3	Technical Assistance Services Assumptions 

  
 For Remote Technical Assistance the following assumptions will apply: 
  
 Technical Support Services (2nd & 3rd Level) will be provided by Nortel Networks at its cost
and expense during warranty to the Hardware elements covered by this warranty. 
  

	 	•	In the event that Axtel fails to comply with the requirements described in section 1.1.2 (Axtel Responsibilities for Technical Assistance), Nortel Networks will advise Axtel of its
non-compliance. Nortel Networks and Axtel may then agree upon service to be provided at the then-current time-and-materials basis published by Nortel Networks plus any travel and living expenses incurred 

  

	 	•	Nortel Services provided under this Annex G are warranted in accordance with Section 6.3 of this Agreement. 

  

	 	•	Nortel Networks, or a skilled, qualified third-party authorized by Nortel Networks, will furnish these Services. 

  

	1.1.4	Technical Assistance Services Exclusions 

  
 The following exclusions will govern the delivery of Remote Technical Assistance: 
  

	 	•	Software provided by Nortel under this Agreement has no warranty. 

  

	 	•	Providing advice on how to detect and resolve network-related problems 

  

	 	•	Diagnosing issues related to Nortel Networks products interfacing with non-Nortel Networks products 

  

	 	•	Analyzing trace / log / dump / Operational Measurement (OM) information 

  

	 	•	Emergency Recovery 

  

	 	•	Nortel Networks is not responsible for supporting non-Nortel Networks supplied third-party product(s). Axtel will be responsible for maintaining support agreements with the
OEM/third-party supplier for such product(s). 

  

	 	•	No warranty is provided for: (i) supply items normally consumed during Product operation; (ii) failures caused by non-Nortel Networks products; (iii) failures caused by a
Product’s inability to operate in conjunction with other Customer hardware or 

 software different from the Third Party Vendor Items provided by Nortel Networks under this Agreement
;or (iv) performance failures resulting from services not performed by Nortel Networks or Customer’s use of unauthorized parts or components. Warranty will be voided by misuse, accident, damage, alteration or modification, failure to maintain
proper physical or operating environment, use of unauthorized parts or components or improper Customer maintenance. Software is not warranted to operate uninterrupted or error free. 
  

	 	•	Nortel Networks support obligations are expressly conditional upon the products not being (i) subject to unusual mechanical stress or unusual electrical or environmental conditions;
(ii) subject to misuse, accident or disaster including without limitation, fire, flood, water, wind, lightning or other acts of God; or (iii) altered or modified unless performed or authorized by Nortel Networks

 Upon receiving
AXTEL’s request, Nortel Networks will allocate a part request number (also known as a Return Material Authorization number) to each FRU to be replaced and notify AXTEL of the relevant part request number. 
  
 Following allocation of the part request number(s) Nortel Networks will
repair or replace the unit at its discretion and will use commercially reasonable efforts to deliver the repaired unit or an equivalent to AXTEL within 60 days. 
  

	1.2.1	Axtel Responsibilities for Repair Services 

  
 Axtel will be required to: 

	

	 	•	Pay the expense of shipping the defective FRU to Nortel Networks warehouse in Mexico City or the closest Nortel Networks’ regional logistics center. 

 

	 	•	Use the specifically assigned part request number(s) provided by Nortel Networks and include completed Nortel Networks Fault Report Forms when returning any FRU

  

	 	•	Adhere to Nortel Networks’ packing instructions (including anti-static precautions) when returning the defective unit 

  
 Note: The packing instructions are included
with the return instructions accompanying the replacement FRU. 
  

	 	•	Put the replacement FRU into service 

 Note: On-site repair and on-site replacement services are not included with the Return
and Replace Service. 
  

	1.2.2	Assumptions for Repair Services 

  
 The following assumption will govern the delivery of Warranty Repair Services: 
  

	 	•	Nortel Networks will incur the expense of shipping the repaired unit or the replacement unit to AXTEL using a method and carrier selected by Nortel Networks. Nortel Networks is
responsible for loss of, or damage to, an FRU while it is in Nortel Networks’ possession or in transit to AXTEL, as well as, to pay all applicable duties, taxes, and other charges associated with the importation of the repaired or replacement
FRU into the country of destination. 

  

	 	•	Unless required for operational reasons and agreed upon with Nortel Networks, the replacement FRU will be at the then-current hardware and firmware release levels as they are made
Generally Available (GA) by Nortel Networks. Upon a specific request of Customer for repair of a quantity of RTU with a specific software release version, the parties will work together to define a mutually agreeable process to satisfy such specific
request, provided that, such a process does not cause Nortel Networks to incur any out of pocket expenses or material additional cost. 

  

	 	•	Warranty on units repaired (FRU) by Nortel Networks to be limited to ninety (90) days from delivery of repaired part or to the end of the original warranty period, whichever is
longer. 

  

	 	•	The defective FRU returned to Nortel Networks becomes the property of Nortel Networks and, subject to Nortel Networks’ receipt of the defective FRU, its replacement becomes
AXTEL’s property. 

  

	 	•	Nortel Networks reserves the right to reject the return of any FRU that does not clearly display the specific part request number [Return Material Authorization (RMA) number] or

	2.2.6	Case Progress Status 

  
 Nortel Networks Technical Support use the following status to differentiate the case conditions during the evolution of the case investigation. A set of status, its related meaning and its relationship with the case
age, are defined in the table below: 
  

					
	 Status

	  	 Description

	 	 Nortel Clock

	 Newly Opened
	  	This status is the default. It signifies that no work has been done on the case.	 	Start
			
	 WIP Level 1
	  	This status is used when a NTS Engineer is actively working on the Case.	 	Not Stopped
			
	 WIP Level 2
	  	 This status is used when a Second Level Support Engineer is actively working a case
 * Second Level Support: Software Support, Product Support.
	 	Not Stopped
			
	 Escalated To Design
	  	This status is used when a Design Engineer is actively working on the case	 	Not Stopped

					
	 Status

	 	 Description

	 	 Nortel Clock

	 Answer
 From Design
	 	Design Engineer has concluded its investigation and has replied back to the NTS Engineer	 	 Not Stopped

			
	 With A
 Customer
	 	During the course of conducting their research, the NTS Engineer may need additional information or activity from the Customer. The “With a Customer” status is assigned when the NTS
Engineer is waiting on a Customer response in order to continue investigation	 	 Stopped

			
	 Interim
 Solution
	 	If a temporary solution is provided that eliminates the customers pain until a permanent solution can be delivered, RQMS requirements allow the case to be set to an “IS” status
during this window of time if approved by the Customer. In calculating case age, this interval will be discounted if the permanent fix was delivered on the negotiated commitment date. If the permanent fix does not resolve the reported problem, case
status shall be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the IS, the IS time period will be added to the RQMS age of the case.	 	 Stopped

			
	 Future
 Deliverable
	 	Customer agrees to live with the problem condition and that the fix will be delivered as part of a future Nortel product release (software release, maintenance release, documentation release
or hardware revision. Requirements to use this status include Customer consent; fix identification, and delivery commitment. This status code does not add time to the RQMS age of the case unless the solution fails and the case is moved back to Work
in Progress (Level 1 or 2) status. If the case is returned to a Work in Progress (Level 1 or 2) status after using the FD, the FD time period will be added to the RQMS age of the case.	 	 Stopped

			
	 Solution
 Delivered
	 	Solution Delivered or available for testing and verification. If the delivered solution does not resolve the reported problem, the status will be changed to Work in Progress (Level 1 or 2).
If the case is returned to a Work in Progress (Level 1 or 2) status after using the SD status, the SD time period will be added to the RQMS age of the case.	 	 Stopped

			
	 Pending OEM Vendor
	 	The case has been handed over to an OEM Vendor for resolution	 	 Not Stopped

	2.2.7	Case Resolutions Classifications 

  
 Nortel Networks Technical Support case resolutions, which shall be mutually agreed for each case: 
  

	 	•	Cannot Reproduce: After 60 days and a reasonable effort, a problem has not been observed in the Network, is not reproducible or sufficient information has not been provided
to adequately troubleshoot the problem and isolate the root cause 

  
  

	 	•	Customer Process: Human errors are present or the customer has failed to follow procedures recommended and documented by Nortel Networks 

  

	 	•	Design Intent: The functionality required by customer does not align with the design specifications of the product set forth in Agreement, in which case Nortel Networks shall
make clear to Axtel which is such design specification (i.e., the functionality is unsupported), and the issue can only be resolved through new development efforts subject to a separate product development agreement and charges.

  

	 	•	External Cause: Issue caused by non-Nortel Networks products 

  
  

	 	•	Hardware Deficiency: A problem is isolated to defective hardware materials or workmanship or substantial nonconformance to specifications published by Nortel Networks

  

	 	•	Hardware Failure: A problem is caused by a hardware component failure that falls within Mean Time Between Failure (MTBF) limitations 

  

	 	•	Nortel Networks Literature: Required Nortel Networks technical document does not exist or the contents of an existing document are in error [for example, an incomplete Nortel
Networks Technical Publication (NTP)] 

  

	 	•	Nortel Networks Process: A problem occurs as a result of a Nortel Networks process deficiency 

  

	 	•	Opened in Error: The case should not have been opened 

  

	 	•	Scheduled Event: An outage occurs resulting from planned maintenance, installation, or manual initialization, including such activities as parameter loads, software/firmware
changes, and other OA&M activities
