relationship with EMBRATEL with other operators, considering the total traffic of its local services. This net amount shall be the difference between: (1) the amount to be received or paid by EMBRATEL to the other operators not taking into account
the traffic corresponding to the Voice Service calls and (ii) the amount to be received or paid considering this traffic.

6.1.2 Until Income is financially positive, the amount informed by EMBRATEL shall be based on the estimate of collection deriving from the Voice Services, referring to the accrual month.

EXHIBIT III
SLA Technical

The technical requirements for the maintenance and operation of NGN, IP and HFC Networks shall be detailed in MPPO to be agreed upon between the Parties.

Functional parameters to be observed by EMBRATEL at its IP Network:

  Round-trip-delay lower than 75ms  Jitter lower than 30ms 
    Loss of packets lower than 1%
    99.9% Voice Service availability

Functional parameters to be observed by NET at its IP Network:

Round-trip-delaylower than 75msJitterlower than 30ms.
  Loss of packets lower than 2%
  99.9% Voice Service availability

Jittermeasurement methodology the Voice Service availability shall be defined by common agreement in MPPO.

Both EMBRATEL and NET undertake to endeavor their best efforts so that all the occurrences of failures at NGN, IP Networks of both Parties and HFC to be solved within no later than twenty-four (24) hours.

The measuring parameter for interconnection route with telephony networks shall not exceed one per cent (1%).

Total congestion rate shall not exceed four per cent (4%).

The team of EMBRATEL and NET, devoted to services and support for identification, diagnosis and retrieval of failures, shall operate 24 hours, 7 days a week, 365 days per year.

Each Party shall make available to the other party access to their network management systems, allowing the assessment of Voice Services quality. The magnitude of visibility of these accesses shall be defined in MPPO.

Each Party shall make available to the other Party a Massive Failure Report at its Network, within no later than twenty-four (24) hours after failure is solved. The report shall contain: (i) the cause for the failure; (ii) the number of end
  customers affected; and (iii) the procedure adopted for resolution.

As to Numbers:

  The telephone numbers that will feed the systems, as well as the definitions of local areas, shall be in accordance with the Switched Fixed Telephone Service Number Plan - STK, regulated by ANATEL; 
    The phone numbers made available by
  EMBRATEL for the Voice Service shall comprise the Local Areas of the cities defined by the Parties in the exploration of Voice Services;

##### 

  The sending of numbers for sale by EMBRATEL shall occur on a monthly basis, up to the fifteenth
  (15th) day of actual month, in order to meet the Estimate of Demand of the subsequent month, as defined in the Estimate of Demand;
    The sending of numbers on an emergency basis, upon request of NET, shall be provided by Embratel,
  observing the same process of periodic sending of numbers, with terms to be defined in MPPO.

In order to understand the expressions used herein, the following definitions shall be used: 
- Massive Failure: this is the total non-availability of equipment, such as CMTS, routers and other elements of NGN and IP networks, affecting the Voice Services. -Round-Trip Delay:this is the time that an IP packet takes to go from one point to another point of the network, by an issuer, until receipt and the sending of a packet confirming receiver to issuer. 
- Jitter: this is the average value of all incremental delay differences, from start of measurement to current packet. 
- Loss of packets: this is the percentage of packets lost in relation to the total number of packets sent during connection. 
- Local Areas: the number of local area associated with a certain location as established by the STFC services number plan.
