Methods and apparatus for connecting a telephone subscriber to a peripheral device

摘要

An electronic switch in a telephone system provides automatic connection of a subscriber going off-hook to a SN/IP, while at the same time remaining responsive to dialing by the subscriber. The switch also permits access code dialing connection to the SN/IP and provides dial pulse to DTKF conversion over the connection path. Upon request by a off-hook subscriber connected to the SN/IP by the switch, the SN/IP can perform dialing or invoke other call features which will be processed by the switch as if requested by the off-hook subscriber.
