Abstract
Line condition reporting and subscriber polling apparatus employs a central processor for accessing subscriber cable pair via one of plural interface circuits, a trunk selection matrix, a test or no-test trunk, and the subscriber's central office. Subscriber lines may be seized in accordance with manual or automatically entered information via system input terminals, and an operative code-forming part of the input command, determines whether the system will operate in a line testing and/or polling (as utility meter) mode. In accordance with one aspect of the present invention, digital computer apparatus is employed both for data processing and assembling purposes, and also for circuit control. Further, such circuit control is advantageously effected by a dedicated microprocessor with ancillary instruction (ROM) and read-write (RAM) memories.
