Extended public switched telephone network architecture with enhanced subscriber control on call setup
First Claim
1. An extended public switched telephone network providing an originating subscriber an enhanced dialing procedure to directly access a specifically selected station among plurality of stations of a terminating subscriber, comprising,originating station instrument with,means to signal via dialed digits on an originating subscriber line, said selected station'"'"'s address and said terminating subscriber'"'"'s identity,originating central office with,means to detect and to transmit information signals on originating subscriber'"'"'s identity,means to detect and to transmit information signals on said dialed digits of said selected station'"'"'s address and said terminating subscriber'"'"'s identity,terminating central office with,means to apply alert signals to terminating subscriber line based on said terminating subscriber'"'"'s identity,means to deliver information signals representing said originating subscriber'"'"'s identity, and said selected station'"'"'s address,network facilities with,means to transmit said information signals representing said originating subscriber'"'"'s identity, said terminating subscriber'"'"'s identity, and said selected station'"'"'s address,means to establish speech path between said originating central office and said terminating central office,customer premise switching module with,means to detect said alert signals,means to decode, analyze and screen said information signals representing said originating subscriber'"'"'s identity and said selected station'"'"'s address,means to control plurality of stations,means to route said alert signals to said selected station among said plurality of stations,means to establish speech path between said selected station and said terminating subscriber line,said originating central office further comprises,means to establish speech path between said originating subscriber line and said network facilities,said terminating central office further comprises,means to establish speech path between said network facilities and said terminating subscriber line,wherein said network sets up a telephone connection on single line services from said originating subscriber, via said originating station instrument, said originating central office, said network facilities and said terminating central office through said customer premise switching module to said selected station specified by said originating subscriber, without any further action of said originating subscriber subsequent to initial phase of dialing said selected station'"'"'s address and said terminating subscriber'"'"'s identity.

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.
