ABSTRACT:
There is described a remote switching terminal which functions as a concentrator switching stage for a central office switching system, such as a standard No. 5 crossbar switch. The remote station connects subscriber phones directly into the horizontal lines of the crossbar, which are fewer in number than the subscriber lines that normally tie into the vertical lines of the crossbar. Control of the remote station is by a microprocessor which communicates over a data link to a microprocessor at the central office. Cross connections are duplicated at the remote station so as not to interfere physically or electrically with the operation of the central office equipment.
