Communication system

Abstract: A communication system for processing information for distribution, including: a central data station, a plurality of user stations, each of the user stations including a plurality of components forming a secure path for the proper distribution of the information, a communication link interconnecting the user stations with the central data stations, the central data station including means for periodically interrogating a user station for determining the operational status of each of the components, means located within the central data station for indicating an error condition in any one of the components, and means at the central data station for transmitting a condition signal from the central data station to the user station for indicating the error condition.

Description: This invention relates to a communication system for processing mailpieces requiring payment of postage for distribution. The United States currently has the world's largest postal system. The U.S. Post Offices currently handle in excess of 100 billion pieces of mail per year, about half the total volume handled throughout the world. The servicing of mail delivery involves three essential steps; collection, sorting and delivery. Collection takes place through a series of post offices spread throughout the United States. The United States has about 30,000 post offices that provide mail services in addition to 9.000 smaller postal centers which provide some kind of some type of mail service. Postal employees typically take letters and packages from mailbox facilities to the nearest local office where it is accumulated for the sorting procedure. At the post office, postal clerks remove collected mail from sacks, bundle packages and segregate mail by size and class into separate categories. The mail travels by truck from local post offices to a central facility known as a sectional center. The United States has 264 sectional centers, some of which serve hundreds of local post offices. The sectional center processes nearly all the mail coming or going from its region. At the sectional center, high speed automated equipment sorts large volumes of mail. The postal service currently uses two sorting systems. One system is devoted to letters and other first class mail, and the other system, for bulk mailing, is used to sort packages, magazines advertising, circulars and other large mails. The letter sorter process involves manually moving mail sacks onto moving conveyor belts, which carry the mail to a machine called an edger-feeder which sorts it according to envelope size. The postal service regulates the size of envelopes to make such mechanical sorting easier. The edger-feeder feeds the letters into another machine known as a facer-cancellor. Sensing devices of the facer-cancellor determine where the stamp is located on the envelope, and enable the machine to arrange the letters so that they all face in the same direction. The cancelling portion of the mechanism then cancels the stamp by printing black lines and the like over it so that it cannot be used again. The machine also prints a postmark on the envelope, including the date, the name of the sectional center, an abbreviation for the state and a three, four or five-number zip code. In addition, the postmark records the time period during which the letter was received at the post office. A computerized machine known as a zip mail translator sorts the postmarked letters according to their destination post office. Postal workers selectively activate the machine's keyboard to send each letter on a conveyor belt into one of hundreds of bins. Each bin holds mail for a different post office. Mail addressed to locations outside the regions served by the sectional center are transported by truck, airplane or train to other sectional centers for further sorting. Finally, postal clerks hand sort mail for the area served by the sectional center into bundles for each delivery route. The zip mail translators in some postal areas have been replaced by more advanced computerized machines called optical character readers which read the zip code on the letter, and pass the mail to another machine that places a series of marks known as bar codes onto the envelope. Additional mechanisms read the bar code and sort mail according to the regions indicated by said bar code. Mail addressed to locations within the regions served by the section center is sorted again by other bar code readers according to destination post office and then according to delivery route. An expanded nine-number zip code, chiefly for use by high-volume mailers, enables the post office to substantially reduce some of this essential time consuming and extensive sorting services. The same processes apply to sorting bulk mail. Current estimates indicate that the foregoing processing tasks necessarily involve in excess of half a million employees. Cost of maintaining and supporting sorting services at the central post office facilities, even including large scale use of automated equipment, has become staggering. Projections of substantial increases in volumes of mail being transported through central facilities, even with the advent of private delivery, telecommunications services, facsimile services and the like indicate that a rapid expansion will be required of such facilities. Since the postal service is a private corporation and is expected to become self-supporting, rapidly advancing postal rates place greater and greater burdens on both users and the postal service in order to support such volumes of mail. In recognition of capabilities of certain high volume users to provide services to central postal facilities, which services may improve efficiency and reduce the amount of processing time required by the central serving facilities, the U.S. Postal Service offers substantial reductions in rates, provided that a user comply with certain requirements which will allow the U.S. Postal Service to take advantage of certain user-provided facilities to reduce its own work load. The concept of work sharing, wherein a user provides certain of the processing activities prior to delivering the mail to the central postal facilities has been proposed and is therefore a positive innovation in the field of mail processing which may have a substantial impact in the future implementation of mail services. However, placing a burden on the user to provide certain of the facilities and services which the U.S. central post office facilities now provide is an equally heavy burden for the user, and must be done in a manner which permits the user to realize substantial savings with its own increased work load by taking advantage of the reduced postal service rates while not exceeding the reduction in rates by the serving costs of providing such services on its own. The Postal Service has already recognized the ability of users to preprocess certain kinds of mail and will accept mail in bulk delivered from a processor along with certification that its procedures have been complied with, and will accept such certification as prima facia justification for reduction in postal service rates. Thus, for example, manifest systems, wherein a manifest is provided to the central post office representative of a group of documents preprocessed by the user, are already known and do allow the user to realize a substantial reduction in rate. One form of such a system is described in US-A-4,837,701 which discloses the features of the preamble of claim 1. However, a large number of additional services, aside from manifesting services, may also be provided by the user and accepted as such by the central processing facility of the postal service in exchange for rate reductions. These additional services, however, require interface communications between the central service and the user so as to maintain within the user's facility information regarding internal postal procedures, such as rates, volume, quantity discounts and the like in order for the central post office facility to accept as valid a certification by the user that certain procedures mandated by the Postal Service have been complied with. The automation of such processing, through the use of telephone or other data communication links, is essential to the successful operation of such a system. The use of communication interfaces are known. However, the problems with maintaining integrity of such a system, allowing for maintenance, or the ability locate mail-pieces within a system, or the ability to train new users remains a serious limitation. It is therefore a principal aim of the present invention to provide a system and apparatus within a user facility which will both operate and maintain, in current fashion, certain preprocessing facilities which can be certified and accepted as properly performed via such certification by the central processing facilities of the U.S. Postal Service in order to qualify for substantial reductions in rate. In accordance with the present invention, there is provided a communication system for processing mailpieces according to claim 1. Features and advantages of a specific embodiment of the present invention include:- to provide a self-contained apparatus which will operate substantially without the intervention of human operators, to automate the internal processing facility at a user location while maintaining sufficiently proper standards with regard to U.S. Postal Service requirements so as to provide certification in a manner acceptable to postal authorities; to implement a user operated certification system with sufficient security consideration to satisfy the U.S. Postal Service of the integrity of a user operated service sharing facility; to provide a system and apparatus within a user facility which will both operate and maintain, in current fashion, certain preprocessing facilities which can be certified and accepted as properly performed via such certification by the central processing facilities of the U.S. Postal Service in order to qualify for substantial reductions in rate by the use of bidirectional communication links, and in so doing to utilize the communication link to augment and update database facilities at the user and base stations so that facilitation of user limited facilities may be expanded beyond the user capacity by interaction with the larger central station; to provide a system and apparatus within a user facility which will utilize the communication facilities of the system employed herein to implement inspection services, diagnostic analysis and repair procedures; to provide a system and apparatus within a user facility which will utilize an article certification as a code line through a communication link to track an individual piece of mail; and to provide a system and apparatus within a user facility which will enable a central facility to permit the transmission of graphic material for the purpose of inclusion within a postage metering application. Systems relating to work share features are discussed in EP Published Application No. 373972A claiming priority from U.S. 285,146 filed 16 December 1988; EP Publication No. 356,228A; and U.S. Patent 4,714,761. These applications relate to the concept of using certain limited user-provided services but do not encompass the full range of work sharing and data sharing services concepts presented herein. The U.S. patent relates to accounting and billing and does not solve the problem of relieving the postal service of substantial service burdens in an effective manner. Prior art manifesting or passpost systems, while allowing some form of certification, are difficult to implement in small user situations and are also cumbersome in their requirement for an additional document to accompany the delivery of mail to the postal service. A method and apparatus is described herein for work sharing including information sharing between participants as well as self-contained automated processing facilities relative to specific requirements set forth by the postal service along with certification of compliance with such requirements acceptable to the Postal Service. Specific certification requirements include analysis by the user of mail composition, currently known as 3602 Information, in accordance with the specific form currently employed by the post office facilities for such information, such composition including weight, volume, classifications, carrier route information, zip code, appropriate bar code, designations, and rate. In addition, other services such as extended presort coding addressing, accuracy of presorts, classification of mail-piece type for machine readability, accuracy of weight and volume in accordance with predesignated discount rates set by the Postal Service in accordance with such factors, and ultimately payment and billing, are all facilities which may be incorporated within a user facility. Incorporation of such information within a user facility, coupled with intercommunication capability between such user facility and a central postal facility, gives certain additional advantages to both user and postal facility which are inherent in the nature of information processing. Thus, the user facility may keep track for accounting purposes of its mailing and other processing as well as funding and volume uses while the Postal Service may employ intercommunication with many of these user units to forecast workloads, transportation requirements, the management of asset inventory, the creation of mailer profiles, and other information which may be employable to establish process controlling to better manage the U.S. Postal Service resources. In addition, by making certain requirements of the user equipment, the requirement of range of operation of the central service facility equipment may be substantially narrowed. Thus, common fonts may be provided through user equipment which will reduce the requirement of central service facilities to have multiple font capability in optical character recognition. The advantages of a telephone telecommunication link existing into the user equipment may be of further assistance with regard to other specific service functions. Thus, for example, the manufacturer of the equipment may be able to maintain a central service facility linking itself to all of the field applications of user equipment. This would be an important characteristic of certification provided by the U.S. Postal Service since it would ensure conformity of operation of all the user equipment in accordance with U.S. Postal Service requirements, as well as ensuring conformity of rate and regulation requirements. An essential element in certification by the Postal Service includes assurance by the manufacturer of the integrity of the scales and accounting systems as well as the metering and certification stamps of the user equipment. In current equipment, such as postage meters, it is sufficient for the user to periodically bring the postal meter to the Postal Service for inspection. In large scale equipment, such as is employed in accordance with the concept of the present invention, bringing equipment to the Postal Service for inspection would be impractical. It would similarly be impractical for the Postal Service to send an inspector to the user facility, in view of the ultimate number of such user facility equipment in place and in view of the costs to the Postal Service involved in such operations. However, since the concept of the invention includes a telephone link, it is a further object of the present invention to provide a link between equipment at the user location and the central station for automating such a procedure. The system thus provides for the user having equipment herein described coupled to a data center by means of a telephone link. The data center interrogates the user system periodically to determine the status of the equipment. Information that can be obtained during the interrogations can include the usage rate and status of the various components and sub-components of the system. This information is utilized to generate a series of reports to the user considering the status of the equipment, the need for user maintenance and the need for Pitney Bowes service calls. The system enables the scheduling of the service calls by leaving a message on the equipment indicating that a service call had been scheduled at a particular time and even by a specific individual. The two-way nature of the communication link established by virtue of the central station between the U.S. Postal Service and the local user is also capable of two-way transmission. Since the local user has placed a certification stamp onto the individual mailpiece, such certification having a unique identifying characteristic, it is possible for the user, utilizing this same certification identification, to check on the progress of a particular item of mail through the U.S. postal service system. Thus, by the utilization of encryption and bar or other coding on mail pieces, termed key line coding and provided by the local user facility, a database can be established identifying the location of various mailpieces at any particular line in the course of delivery from local sender location, through all central facility location, to local delivery. This information can be captured at several points of entry into the system. The capture points may include the mailer when the mailpiece or parcel is placed into the carrier service, the carrier service when the mailpiece or parcel is sorted, when the mailpiece or parcel is placed into its delivery channel, when it is received at a bulk mail station, when it is received at each sectional station, when it is received at each central station, and when it is placed into local delivery. In this way, key-line tracking of the mailpiece or parcel is utilized to identify the parcel and by so doing with suitable encryption provides the mechanism to identify its location in the system. Finally, the preferred embodiment of the present invention allows the central station to provide communication facilities from the U.S. Postal Service to each of the remote user locations, in package form, which will enable the remote user locations to train employees to become aware of new techniques in mailing, new rates, new types of services, and other means or modes by which the local user may take advantage of the presorting capability for additional rate discounts within his own piece of user equipment. The training packages may be downloaded from the central data station to the local user and may train current employees on new techniques by self-instruction in an interactive mode with the terminal itself. Additionally, new employees may be trained by utilizing the interactive training downloaded in the same manner. The training service is also available to the central station sales and customer representatives to train them and enhance their own abilities to sell equipment to local users. The system also enables downloading the third party advertising, which allow a customer to either provide third party advertising, thereby discounting the cost of its own mailing, or to download interesting graphics or other type of advertising for a particular mailing. The maintenance of a two-way communication link between the central station and each of the user facilities permits the central station to keep a permanent record, available for inspection by the U.S. Postal Service, and which may be employed to confirm uses of any of the local users by cross-check of each of the elements of data which will be considered essential to any specific user application. Thus, each of the user applications is also designed to apply postage. Central accounting and data facilities may be employed to keep track of each user's postage requirements. The communicating link may also facilitate two-way charging and recharging of local postage meters from the central station, also under authority from the U.S. Postal Service, and as have been previously disclosed in prior art remote recharging systems currently in use. Thus, during the on-line periods, multiple quantities of data may be exchanged between the central station and the local user. Thus, the present invention also provides in one embodiment for the employment of a central station with multiple processing ability, capable of high speed data interchange between pluralities of remote local units and itself, and possessing the further capability internally of correlating data culled from each of the remote users which may be employed both for statistical purposes and for the purposes of moderating usage by each of the local users and for insuring compliance with the latest U.S. Postal Service rules, regulations and certification procedures for work sharing. Communication in contrast may also be by means of a code or other form with the relevant information transmitted in encrypted format. The information may be scanned and used to automatically set the postal equipment at the user site to proper settings, both for postage and for usage scheduling, without direct user intervention, thus enhancing security and efficiency. The invention will be better apparent from the following more detailed description of an example of the invention, accompanied by the attached figures, wherein: Figure 1 is a functional block diagram illustrating the relationship between the data center, the U.S. Postal Service, and the local users; Figure 2 is a more detailed block diagram illustrating a data center. Figure 3a-c illustrates flow charts for the data center. Figure 4 is a more detailed block diagram illustrating a user station. Figure 5a-d are flow charts illustrating the operation of Figure 4. With reference to Figure 1, a plurality of user stations designated as U 1 , U 2 ...U n , and identified as 10,12 and 14 are shown. It will be understood that multiple user stations are possible in excess of the three shown, and that these are shown by way of example only. These stations are coupled by means of an interconnection network, illustrated generally at 16, to the data center 18, which in turn may be appropriately coupled by means of a secure line or the like to the U.S. Postal Service 20. The data center is a facility run by a commercial operation, such as Pitney Bowes, Inc., the assignee of the present invention. Each of the blocks 10, 12, 14, 18 and 20 contemplate the use of data processing components, each appropriately interlinked by means of high speed telecommunication links or the like for the purposes of exchanging information. It is also contemplated within the scope of the invention that the U.S. Postal Service will maintain an appropriate computer facility, not otherwise described herein, which will possess the capability of uploading and downloading specific pieces of information upon request by the data center, and relating to appropriate postal rules and regulations which will effect the use of certain discounts in mailing postal rates, as well as other factors necessary for the concept of shared work services which will be certified by each of the individual user stations in order to qualify for reduced rate requirements when mail is received in the U.S. Postal Service facilities. The communication link is also contemplated as a two-way link between units 18 and 20, wherein the U.S. Postal Service will have the capability of monitoring specific operations within the data center in order to ensure that the data center is operational in accordance with rules and requirements which may be imposed by the Postal Service from time to time. The monitoring operation is a periodic unscheduled communication link examination of certain storage areas of accessed memory locations for confirming proper operations. Of course, visual on site inspections and examinations may also be made. With reference to Figure 2, a more detailed functional component relationship of the data center is illustrated. Thus, the data center includes a first data channel 30 which includes a CPU 32 having a program memory 34, a keyboard 36 and an appropriate display 38 coupled thereto. Data communication link 40 interconnects CPU 32 to the U.S. Postal Service 20. The user units 10 are coupled via appropriate telecommunication data links 42 to a second data channel 44 which includes a CPU 46, a program memory 48, a keyboard 50 and an appropriate display 52. The CPU is coupled to the data links 42 by means of a multi-channel I/O device 54 capable of high speed data communication. In operation, two-way communication between the data channel 30 and the U.S. Postal Service 20 provides a continuous interchange of information regarding updates of U.S. Postal Service rules and regulations equired for the continuous certification use by the local users 10. In addition, the data channel 30 may also be manually interrogated by means of keyboard 36 for nquiring of the Postal Service for specific information which may be employed with regard to compliance with certifications, the answering of specific data questions, or other uses requiring specific interrogation by means of the central station to the U.S. Postal Service. Since the U.S. Postal Service link is a two-way communication over channel line 40, it is possible through this link for :he U.S. Postal Service to interrogate and monitor the operation of the first data channel 30 and the second data channel 44, for compliance with quality control and other security compliances which may be required by the U.S. Postal Service. Turning now to the second data channel 44, high speed continuous two-way communication with respect to continuous update of U.S. Postal Service requirenents for certification, servicing and diagnostics, training, and other information interchange, are effected by means of the CPU 46 operating through the high speed data channel 54 interfaced along with communication lines 42 to the multiple user network U 1 , U 2 ...U n . Operating under control of the program memory 48, the CPU 44 is contemplated as a high speed multiple processing information apparatus of conventional design such an IBM 3083 or a DCVAX unit which may handle multiple requests from any one or more of the users simultaneously through the multiple channel I/O device. Keyboard 50 and display 52 may be utilized for manual information interchange between any of the local users and the information operator. Although only a single keyboard display unit is illustrated, it will be understood that data-line 58 is a schematic representation of the existence of a multiple number of display keyboard combinations evidencing the use at the central station of a plurality of key operators available to answer user questions upon interrogation. Referring to Figure 3, a general flow chart illustrating the operation of the arrangement of Figure 2 is shown. The flow chart consists of three portions, Figures 3a, 3b, and 3c. Figure 3a illustrates the program routine governing issuance of appropriate updated nstructions and status checking for compliance with certification operations in accordance with U.S. Postal Service rules and regulations. Figure 3b illustrates a diagnostics and service routine followed by the central processor unit with respect to each of the local user stations by which appropriate diagnostic maintenance and service calls, as well as security monitoring and monitoring of specific internal functions of the postage meter having to do with secured aspects, such as the meter, certification, and descending register funds balances, may be maintained. Figure 3c illustrates a software routine whereby two-way communication regarding the tracking of specific mail-pieces may be accomplished upon user requests. Referring to Fig. 3a compliance with U.S. Postal Service rules is maintained by ensuring that the data center continually and regularly updates the rates and regulations such as postal rates, bulk mail rates, mail size requirements, new zip codes, etc. The inquiry can be initiated by the data center as a periodic status check or by a request to provide an update of the latest rules. The data center thus establishes a data link, identifies the user, as by a code stored in the local unit non-volatile memory. The status of local registers are included, and an alarm condition raised if an anomaly is detected. In the absence of such a condition, the updating is performed. Interrogative real time requests, such as from an on line user, can be dealt with at this time. Referring to Fig. 3B, the central unit routine for establishing diagnostics and servicing at a local user location is illustrated. The routine begins with a service request, initiated by the local user or a service request initiated by the central unit. In either event, after establishment of channel communications, identification of the user by retrieval of a specific identification code stored within the permanent memory of the user location is made. The user configuration is then retrieved at the central unit memory, and a credit check of the user is made. Next, each user function is checked and a decision made as to whether an error exists. If an error does exist, the error reading is catalogued. If the error is not the last error, the system recycles to check additional user functions until an error free routine results. In this manner, each individualized user function may be reviewed. As discussed hereinabove, each piece of equipment contained within a user unit may be reviewed in this manner. Thus, units such as optical scanners, feeders, certification units, postage metering equipment, CPU diagnostic routines, and other routines designed to test and maintain each individual function contained within a respective user unit equipment may be accomplished. At the completion of a complete diagnostic check, and assuming no additional errors were found, a repair schedule call may be programmed by the central unit in accordance with the schedule of the local repair technicians. Once a time schedule has been arranged, the schedule may be transmitted to the user for display upon local screen displays. If the user functions were error free, then the decision block after the checking of each user function, indicating no error, branches the program to a rate update routine. The rate update routine is also branched to at the completion of the transmission of a specific repair schedule, should errors have been found during the diagnostic programming check. The check rate update examines the central program memory of each user unit to determine that the unit has the last, and most recent, rates programmed into the local user unit. If the local unit does not have the correct update, then a downloading of a correct user rate schedule is made along the appropriate transmission channel to the appropriate memory location contained within the user equipment. At this point, the program continues by uploading all local usage data from the local user unit. This local user update can include such information as local user mailing volume, such as destination zip codes in a recent mailing time period, processing or certain types and sizes of mail, and other user workloads so as to enable the Postal Service, by maintaining such information in a stored data base, to forecast workloads, transportation requirements, management of asset inventory, creation of mailer profiles, and other information which may be employable to establish process controlling to better manage U.S. Postal Service resources. Furthermore, this information may be utilized to generate a series of reports to the user considering the status of the equipment, the history or record of user maintenance, and the quantity and time of service calls necessary for servicing the equipment. In addition, the ability of the central data station to communicate between itself and the user facility permits the central station to keep a permanent record, available for inspection by the U.S. Postal Service, to confirm uses of local users of such critical elements as postage requirements and error free data operation which best ensure integrity of the local system to the satisfaction of the U.S. Postal Service requirements, thereby enabling certification processes to be established allowing work sharing concepts to be employed for the purpose of reducing mailing rates. Referring now to Figure 3C, a routine initiated by the local use through the central station for tracking specific pieces of mail based upon encryption keys placed by certification equipment on pieces of mail is illustrated. Thus, a tracking request is received over the two-way data channel link by the central unit. The central unit then requests the encryption key once communication and identification have been established between the central unit and the local user. The next piece of information requested is the originating zip code, and then the destination zip code. The central data station then configures the route normally encountered through the U.S. Postal Service by a piece of mail originating from the input originating zip code and the destination zip code. The configured route will include each of the respective stations, including delivery channels, encountered by a piece of mail normally delivered between the respective inputted originating zip code and destination zip code. Once the configured route has been calculated by the central unit, each of the specific stations on the route are polled, again through the two-way communication link through which the central unit has access, and the specific location of the particular encryption key is determined. Once confirmation of an encryption key at a specific location is confirmed, this information is transmitted to the user station. The user station will then utilize this information, as will be set forth in further detail below, to determine the specific location of the piece of mail pursuant to the user request. Referring to Figure 4, the function block diagram illustrating the interrelationship of components within each individual user station is illustrated. The central user station operates under the control of a CPU 60, which includes a RAM memory and appropriate control registers. Coupled to the CPU 60 is a program memory 62 which defines the essential function of the system, including updating instructions and rates used in the local user units, diagnostic monitoring, a two-way communication link establishing a tracking facility utilizing the encryption key represented by the certification, and interface capabilities with respect to the central station for the downloading of training information which enables operators at local stations to understand and comply with specific requirements imposed by the U.S. Postal Service with respect to the certification process. Coupled to the CPU 60 are a keyboard 64 for the manual entry of data requests and other information into the CPU, display unit 66 and an I/O channel 68 coupled by means of a data link 70 to the central station 18. Accounting information and funding to the local user 10 are effected through the data link 70 from the central station 18 to the remote recharger mechanism 72, operating in accordance with conventional recharging techniques such as disclosed in U.S. Patent No. 4,097,923 issued to Eckert Jr. et al. and assigned to the assignee of the present application. Remote recharging unit 72 charges a descending register 74, in conventional manner, which keeps track of descending balances charged from time to time in accordance with mail requirements. Non-volatile memory unit 76 is employed to maintain security of information during periods of time when local user unit 10 is not operating. Non-volatile memory 76 receives descending register balances as part of a shutdown routine, along with other security data which may be applied from the active memory of the CPU 60. One of the features of the user station 10 is that the remote recharging operation carried on in remote recharging circuit 72 is maintained through the data link 70 to the central station 18, and operates independently of the OFF/ON status of the local user unit 10 for monitoring purposes. Thus, even if the local unit 10 is turned off, central station 18 through data link 70 may inquire through the remote recharging unit of the status of certain pieces of information which are maintained either in the RAM memory portion of the CPU 60 during on-times of the unit 10 or in the non-volatile memory 76 during inactive status periods. The concepts of work sharing entail the performance of certain functions by the user in a secure manner so as to enable the user to apply not only postage but to also apply certification, as an imprint on the mail piece, which will be accepted by the postal service that the services certified were in fact performed by the user and thus enable the user to be entitled to further mail rate reductions. Communication in contrast may also be by means of a code or other form with the relevant information transmitted in encrypted format. The information may be scanned and used to automatically set the postal equipment at the user site to proper settings, both for postage and for usage scheduling, without direct user intervention, thus enhancing security and efficiency. Certification information is provided to the CPU through a plurality of inputs along a mail path designated as 78. Mailpiece documents which are stacked in appropriate feeder-stacker unit 80 are, under control of CPU 60 through feeder-unit 82, driven along the mail path 78, past OCR unit 84 where printed material on the mailpiece is read, past counter station 86 where individual pieces are counted, to the scale unit 88 where the mailpiece is weighed, and thence to a metering station 90 for application of appropriate postage and finally to a certification station 92 where appropriate certification stamps may be placed on the mailpiece to indicate compliance of the mailpiece with all the criteria that have been set under work sharing requirements required under the U.S. Postal Service regulations. Since the unit may be capable of handling prefranked mail, a meter bypass network 94 operating under control of the CPU, provides for bypassing of the mailpiece of the metering station 90 without the necessary application of additional postage. Problems encountered in short-weight mail may be adjusted by appropriate decrement of the descending register balance in descending register 74 under program control through CPU 60, based upon differences detected by the computer between applicable postage rate requirements and the actual mail run being passed through the user station 10. An example of short-weight mail is disclosed in an EPC Published Application No. 393972A. Referring to Figures 5a-5d, the specific software routines governing the operation of the user are illustrated. Thus, in Figure 5a a work sharing flow chart is shown. In Figure 5b the diagnostics flow chart is shown. In Figure 5c mail tracking is shown, and in Figure 5d training and other intercommunication system operations are illustrated. Operation of the system is a complete pass through including all stations, with reject operations taking place at one point, between the metering station and the certification station. It will be apparent to those skilled in the art that other rejection points may be placed along the mail path, however, the high speed nature of the data processing system, with an eye towards the economics, dictates as a preferred embodiment a single rejection station located at the downstream point. All data regarding specific mail runs are accumulated in the CPU, and a rejection or accept decision made just prior to entering the certification station. Thus, referring to Figure 5a, first, all of the data received is analyzed for 3602 requirements, including weight, volume, class of mail, applied rate, etc. This information is correlated by means of the OCR module, a count module and a scale module, taking into account previously inputted data either by means of the keyboard or by means of other inputting means such as an optical character read manifest or a data communication link which comprises a separate input channel into the CPU 60. Each of the elements shown on the flow chart of Figure 5a are program selected in accordance with the program loaded into the CPU governing the application of a specific mail run and in accordance with the work sharing operation selected by the user. Thus, assuming a plurality of work sharing concepts selected by the user for a rate reduction, with the understanding that any one or more of the elements selected as shown in Figure 5a may be eliminated in accordance with the different selected package by the operator, then conformance to the 3602 information next relates to acceptance of zip rate, meaning that mail has been presorted appropriately by zip code, thence to readability, indicating that the mail complies with a certain format thereby eliminating the need of the Postal Service to have multiple format reader devices, thence to a zip plus four address meaning that the mail has been pre-zip coded with the extended zip code thereby reducing the sort capacities and procedures required by the Postal Service, and thence to a presort station indicating that the mail has undergone certain presorts, thereby further reducing the work load of the Postal Service, and thence to a mailpiece type, indicating that the mail is all of a common size and type, thereby further reducing the amount of segregation necessary by the Postal Service, and thence to a postage station, where in accordance with all of the foregoing requirements, the correctly applied postage is confirmed as having been placed upon the mailpiece, either by the metering station, or by means of a pre-applied postage franking mechanism. Failure to apply the correct postage in pre-printed post-aged mailpieces does not result in rejection of the mail-piece, but simply results in the appropriate debiting made to the decremented register in the local user's unit, and thence having the mailpiece passed to the certification station for certification indicating that correct postage has been debited to the account of the user, even though the same may not be appropriately indicated on the mailpiece. By including the certification of correct postage, one last check, that of short paid mail, also does not have to be made by the Postal Service. Thus, compliance with each of the requirements set forth in the flow chart of Figure 5a, representative of a maximized work sharing concept, substantially reduces the work burden of the Postal Service. This enables substantial reduction to be passed back to the user in the form of rate reductions. Compliance with the foregoing, as previously stated, is physically indicated on the mailpiece by means of an appropriately entered certification. Certifications may be appropriately encrypted to prevent duplication, and may be encoded in such a manner as to afford the Postal Service means to validate such certification on a random spot check basis. Methods and apparatus for effecting such verification based upon encryption are disclosed in US-A-4,878,246. Figure 5a also illustrates between each of the respective blocks a plurality of decision blocks or diamonds, indicating compliance or non-compliance with the operation indicated in the previous block. The affirmative outcome of the decision block, indicated by a Y, indicates passage to the next decision making step. A NO or inability to comply with the requirements in the prior block is indicated in the decision block with an N. The outcome of the N is the passage of a signal through the reject station. Such passage to the reject station has been indicated with respect to the first block, and it will be understood that each of the subsequent decision blocks possesses similar capabilities. After the mail-piece size check, the mail piece is passed to a postage check and tested to indicate whether or not the postage to be applied is correct. Assuming it is correct, postage is printed and the mail is passed to certification. If the postage is not correct, the program is passed to the step of decrementing the descending register by the correct amount. If the descending register is not decremented properly, due to insufficient funds in the descending register or the like, the mailpiece is rejected. If it is accepted, it is also passed onto the certification station. If the mailpiece is not pre-franked, the program branches through an additional postage printing operation. Referring now to Figure 5b, a flowchart indicating the operation of the system for effecting service diagnostics is illustrated. The data center interrogates the user system periodically to determine the status of the equipment. Information that is obtained during the interrogation may include the usage rate and status of various components and subcomponents of the system. Information may also include status of the descending registers and any other secured aspect of the equipment which is of interest to the central station and also to the user. This information is utilized to generate a series of reports to the user, including monthly statements, concerning the status of the equipment, the need for user maintenance and the need for service calls by the data center. The system may also enable the scheduling of the service call by leaving a message on the equipment indicating that a service call has been scheduled at a particular time, including leaving the name of a specific service individual, all of which may be displayed on the user's terminal. With specific reference to Figure 5b, service request or status inquiries will have a common effect of initiating this routine. Thus, the status inquiry which may originate from the data center, or a service request, which may originate from the user, both act first to activate and display any prior stored information regarding previous service requests or a service call that may already be scheduled and in progress for display by the operator. The system next interrogates each of the specific hardware element shown in Figure 4, which interact/react with the mail feed path. Thus, the hardware interrogated will include feed mechanism 82, or OCR reader 84, the counter 86, the scale 88, the meter 90 and the certification 92. Each of these devices will include appropriate monitoring circuitry for indicating, in a specific stored location, each of the current status operations of each of these devices. Status may be monitored by means of a startup initialization routine effected by the CPU, and continuously monitored during operation of a mail feed path. Two types of monitoring conditions are evident. First, a monitor condition which suggests the need for service but will not interfere with the operation of the feed path. Such monitoring condition will be continuously indicated by means of a status check. These may be referred to as soft defects. Additional defects which would actually interfere with the operation of the device, such as inability to read at the OCR unit or inability to apply postage due to a defect in the meter, or other inabilities of inoperative devices, known as hard defects, will cause a shutdown of the mail path and provide to the CPU an indication of the specification problem by virtue of the status of each of these devices. The hardware elements are interrogated in turn, and the status report placed in appropriate memory locations in CPU unit 60. Thus, interrogation hardware interrogates a specific hardware unit, and passes the information upon receipt to the status report area of the computer where it is stored in the appropriate location. As indicated in the following decision diamond, if additional equipment needs to be interrogated, an appropriate loop is made back to the interrogated hardware and the previous steps repeated. When all hardware has been interrogated, the interrogation process continues to the CPU registers where sampling of each appropriate register in the CPU which keeps track of specific pieces of information relative to the mail usage is indicated. Thus, the CPU register storage will include information such as statistical data relating to use of the device, number of times appropriate categories and different weight classes have been employed, number of classes used, geographic distribution of mail, statistical data relating to the use zip codes, statistical data relating to the use of specific mailpieces, statistical data relating to the use of bulk mail versus individual piece mail, specific data relating to the use of classification of mail, and other types of information utilized by the specific apparatus which are part of the certification procedure. Next, the descending register balance is interrogated, and then all of the data is accumulated appropriately and transmitted through the high speed data line 70 to the central station. Suitable data transmission techniques are employed with appropriate error checking and confirming feedback signals. Upon failure to confirm transmission, as indicated in the decision block following the confirmed transmission block, retransmission takes place. Although not indicated, standard techniques for repeating the transmission a multiple number of times awaiting error-free transmission may be employed. Final failure to transmit the information error-free will result in a specific alarm raised at the central station indicating that the local user unit is inoperative for transmission purposes. Such a defect would be considered a hard defect, and would result in shutdown of the machine. The hard error HE decision block, based upon a multiple number of unconfirmed transmissions, would result in shutdown, block SD. Upon the confirmation of appropriate transmission, any reply from the central station is awaited by the local user unit in the next REPLY block This reply may include information results regarding diagnostics concerning the local user's machine; it may also include a specific display provided by the central station of the time, date and name of the mechanic who will appear to fit the local user's unit. If the information displayed is to be stored it is placed in the appropriate storage of the CPU for later display upon further interrogation routines or upon status checks by the local user. The routine at this point ends. It will be apparent that the certification stamp thus assures that all critical components are in proper working order as well as that the postage applied is accurate. Flow chart 5c illustrates the concept of mail tracking. The mail tracking utilizes the encryption placed upon the mailpiece by the certification mechanism. It should be understood, however, that mail tracking can take place by additional encryption or bar coding of information on the mailpiece, unrelated to the certification stamp placed thereon. In this embodiment, since the certification stamp is part of the operational process of the machine, and is an encryption coded key line, it is convenient for the system to utilize this keyline piece of information for mail tracking purposes. After release of the mailpiece from the local user's station and delivery to the central postage facility, and assuming the use of all automatic equipment in the central postage facility based upon the work sharing concepts reducing the amount of effort necessary by the central post office, information is captured at each entry point. By the use of appropriate OCR or other reading equipment, each entry point into the delivery chain after release of the mailpiece by the local user may be a data input point. Thus, the delivery service may possess input equipment which allows each piece of mail upon transfer to the delivery service to be inputted into a central data base system indicating the specific location of the mail-piece. Upon transfer of the mailpiece from one location to the next, an appropriate tag or data line is placed upon the mailpiece certification encryption keyline when entered into the data base. By coordinating the data through the U.S. Postal Service central data base, at each entry point into the system, the operator may be able to inquire, through the central station and thence through to the U.S. Postal Service, by keyline, of the specific location of a mail-piece. Since each mailpiece certification keyline will have a tag attached thereto, which is continuously updated as the mailpiece goes from input point to input point along the delivery chain, the user should receive back an indication based upon such added keyline of the location of the specific mail-piece. In this way, the keyline tracking on the mail or parcel is utilized both to identify the parcel and by so doing with suitable encryption enable the mechanism to identify its location in the system. Referring now to the flowchart, each step in this process as it occurs in the user status CPU is illustrated. First is the inquiry step, effected by transmitting an inquiry request through the keyboard of the local user station into the CPU and thence to the I/O device and across the datalink into the central station. In the central station such inquiry request is recognized and transmitted between the two opus out across the datalink to the U.S. Postal Service communication facilities. In the local unit 10, the inquiry request is routed to central and a confirmed transmission, with hard error time out and appropriate alarm, results in a reply of a code line which is analyzed with the CPU to strip out the suffix locator code, which is then compared in a lookup table data base previously incorporated in the CPU from downloaded information received from the central station for identification based upon such suffix, and the result displayed on the display terminal of the local user. The downloading of information for the purpose of allowing communication such as training packages and other information to be transmitted from the central unit to the local units is illustrated in Figure 5d. The ability to download information in large quantities allows the central station to provide training packages to the local station, which may be employed by the local user for training new employees and acquainting new employees on various postal procedures and other means and manners which by postal efficiency may be achieved under the work sharing concept. This includes training current employees in new techniques in mailing and also may be employed as a self-instruction mode interactively with the terminal for assisting in the training of employees. The system also allows downloading of third party advertising to allow a customer to provide third party advertising, thereby further discounting the cost of their own mailing, or to download interesting graphics or other type of advertising for a particular mailing. Referring to Fig. 5D, a training inquiry is initiated by keyboard and local users. The request is routed to the data center. In response, the data center transmits a code representing the most recent updated training package. Upon receipt, the local user compares this code to its most recent coded update previously stored in local memory. If the latest data center program matches the stored program, the downloading step is shipped and the training program begins as an interactive subroutine. If it is not the latest version, the downloading is completed and the subroutine runs with the latest version in local memory. Thus, each local user training session will employ the latest up-dated training package. The foregoing preferred embodiment may be varied without departing from the invention. The appended claims are to be interpreted in accordance with Article 69 EPC and its Protocol. This specification was originally drafted for a U.S. patent application. References to the U.S. Postal Service and "zip" codes should be treated, where appropriate, as referring to the postal service or the post codes of any relevant country.
