There is disclosed an apparatus for interconnecting a plurality of communications mediums, including voice frequency and broadband frequency to a subscriber communications system at the subscriber's premises. The apparatus comprises: 1) a controller for coupling and de-coupling communications mediums comprising at least one public service telephone network (PSTN) line and at least one non-public service telephone network (non-PSTN) line, to a communication system within the subscriber's premises; 2) lightning protection for controller interfaces; 3) a detector circuit for detecting power loss in the non-public service telephone network connection and 4) fail-over (re-connecting to an alternate circuit) devices connected to a public service telephone network line; and 5) a test circuit for monitoring the condition of a backup power supply for the apparatus.

System and method for interface between a subscriber modem and subscriber premises interfaces

There is disclosed an apparatus for providing automatic call distribution and auto-attendant capabilities to a digital telephone switch not having those capabilities. Digital interface circuitry is provided to emulate the appearance of a digital telephone connected to the telephone switch. The telephone switch is programmed to automatically route incoming calls to the interface circuitry and also to transmit the status of other digital telephones connected to the telephone switch to the interface circuitry. A processor is provided which determines the busy/idle state of other telephones connected to the switch, and transmits to the telephone switch a transfer command which re-routes the incoming telephone call to an idle telephone. Storage circuitry is provided for storing a user-defined algorithm for distributing incoming calls to the available digital telephones. Storage circuitry is also provided for storing digital audio messages for replay to the incoming calls when the incoming calls are placed on hold by the processor means.
