Abstract
Apparatus and methods for a remote cable switching system for selectively switching pairs of an incoming trunk to one or the other corresponding pairs of two available outgoing trunks are disclosed. The system includes at least one remote switch module, a normally quiescent remote control module, and a central office controller which provides the remote control module with operating power and with switching commands during a command sequence. The remote control module accumulates power and decodes the sent switching commands in order to operate identified bistable switches of the switch module to establish the desired matrix. Circuitry for remotely testing proper tip-ring orientation of the connected pairs is provided at the central office is also disclosed and claimed.
