Abstract

This description provides a technique useful in the maintenance of remotely located terminal systems, which,permits a customer engineer to time-share a connected processor for locating, identifying, and possibly even repairing a communications system. The customer engineer is provided with the full computing power of the processor by the addition of a maintenance line adapter. This adapter has the specific purpose of interfacing the maintenance panel of the equipment with the processor via the scanner and 10 interface associated with the processor. From the maintenance panel, the customer engineer can interrupt the active processor program to indicate via panel switches the function or test he wishes to be performed.

Time Shared Interactive Maintenance Feature

This description provides a technique useful in the maintenance of remotely located terminal systems, which,permits a customer engineer to time-share a connected processor for locating, identifying, and possibly even repairing a communications system. The customer engineer is provided with the full computing power of the processor by the addition of a maintenance line adapter. This adapter has the specific purpose of interfacing the maintenance panel of the equipment with the processor via the scanner and 10 interface associated with the processor. From the maintenance panel, the customer engineer can interrupt the active processor program to indicate via panel switches the function or test he wishes to be performed. Maintenance support software in the processor will (on a time-shared basis with the application programs) perform the requested routine. The maintenance line adapter provides a data path from the maintenance panel directly to the processor. As a result of this, little control logic is needed, and the hardware required to implement the function is minimal. Maintenance logic in each of the communications line adapters is thus reduced.
