DTS-70:
Digital Test Simulation is a technique in which the circuit to be tested is modeled, component by component, and node by node, in the test system computer. From this model, the attached processor (HP-1000) can calculate the correct responses to any input pattern, plus predict failure models and their responses. This allows only those patterns which identify the most faults to be used as the test pattern stimulus, thus optimizing test time and repair.
A major benefit of this installation was its capability to provide an accurate measurement of on-site test and in-house repair effectiveness. The implementation manager can determine to what extent the various board components are being exercised, and thus can determine the test efficiency.
Another benefit is rapid and inexpensive fault location. The DTS-70 accesses faulty board models developed by the simulator and guides the operator in a quick series of probe tests to isolate the faulty component(s). Due to its time delay capability, the DTS-70 can also locate intermittent faults, and thus allowing the technician to detect race conditions.
At project approval, the estimated period to pay-back was 5 years. Actual pay-back was 3.8 years, with a total project life span of 10 years.
Logistics can be further defined as the composite of various considerations, including:
The Mechanized Inventory and Management System (MIMS), supported by a UNIX Operating System, is a computerized data base that serves the needs of the Computer Maintenance Control Center (CMCC) and the Computer Maintenance Group (CMG) self-maintenance effort. MIMS is a set of algorithms to administer the Parts Inventory Control, Trouble Ticket Tracking, Components Inventory Control, Maintenance Units Data Base, and Personnel Administration.
The operation and application programs resided in a DEC PDP-11/70 (Digital Equipment Corporation) computer located in Newark, at 1 Washington Park. The data bases are structured, random accessed files that are controlled by the various administration functions.
MIMS is designed to facilitate the concept of remote sites and a centralized administration location. The central administrative location will handle all company related functions (such as: training, vacations, payroll, time cards, vouchers, etc.), as well as being the "warehouse buffer" stock of spare parts for the associated remote sites.
REQUIREMENTS:
Its features included: Front-end audits to eliminate the storage of erroneous data; retention of customer records between the time of sale and cutover; implementation coordination (machine-to-machine interfaces, scheduling capabilities, and tailored outputs); and preinstallation change control.
MCS interfaced directly (without human intervention) with the Business Service Center by producing a tailored (translated) magnetic tape, which is loaded into the BISCOM/OCS network. Thus making the ubiquitous service order obsolete. This magnetic tape contains a final error-free customer account record, ready the day after the cutover for review by the Business Marketing Staff and the customer.
At the final revision, November 1980, MCS existed as an expert shell and five tailored expert systems, separate but coexisting on a single DEC PDP-11/70. The expert shell consisted of a profile algorithm capable of allocating and initializing the necessary data bases, overlaying and modifying the application modules to build each expert system, resetting the permissions to safe-guard the customer's data base, and finally, once the tailored expert system was in place, inhibiting itself (the profile algorithm for that particular customer) from initializing his data base file again. This expert system was encoded with the knowledge of a Business Staff expert in Centrex sales. An expert system differs from a conventional computer program in that it includes rules for decision making, the same rules a human expert would apply to specific situations. Those rules are programmed so they can be applied to the information contained in the customer's data base file.
MCS was one of New Jersey Bell's first expert system capable of administering multiple due dates for several Centrex cutovers on a time-shared basis. In essence, what was developed was an expert shell that was capable of writing an expert system for itself that was capable of programming another business computer (DEC PDP-11/70 to DEC PDP-11/70 to IBM 370). This concept can easily be expanded, as a final product, to encompass Dimension sales and cutovers as well.
General Manager Business Service, Jerry O'Loughlin said, "MCS is the most fundamental and significant development in the processing of information associated with customer accounts in years, if not in the history of our company. It puts information in a format designed to fit the needs of each department involved in the job, and just about gets rid of the ubiquitous service order. On the day of the cutover, which may be 6 months to a year after the proposal by Business Marketing, we merely 'push a button' and all the important billing information for the entire job comes out immediately, and it comes out correctly. Now after a complicated cutover, a team from Business Marketing, Business Services and Accounting has to sit down and review the first bill in detail, making all necessary corrections. With MCS the initial bill is ready the day after the cutover, and it's error-free."
