ABSTRACT:
A telephone call setup technique, based on an expanded originating subscriber dialing procedure, utilizing existing Public Switched Telephone Network (PSTN) facilities, provides a remote control means to directly instruct a customer premise switching module at the end of the terminating subscriber loop, which automatically routes the call to a terminating subscriber's station specified by the originating subscriber. This technique essentially expands the definition of PSTN's automatic switching system boundary to the end of every subscriber loop. Not only individuals on a residential premise can be reached separately, but also the on-demand switched data communications can be routed through PSTN to specific terminals without the concern of disturbing occupants on the premise. The architecture of this system also provides PABX functions to residential single line telephone services. This technique replaces the basic auto-attendant functions on PABX's. Furthermore, with the station addressing procedure (secondary dialing) converged back to the originating central office, subscribers using decadic pulse dialing telephone station instruments, which could not perform end-to-end signalling, can now directly access terminating subscriber's stations, as if they were directly connected to PSTN individually.
