ABSTRACT:
Disclosed is an arrangement for "seamlessly" integrating telephone services relative to primitive analog telephone equipment into general purpose computer systems. The integration is effected through present "secondary" adaptation of data link control adapter devices which are adapted primarily for coupling such computer systems to high speed data communication links for transmission and reception of digital data. This permits general resources of the computer system (keyboard, memory, disk drives, etc.) to be used for specific applications associated with telephone services. Presently described link control devices have a telephone attachment port which couples through analog-to-digital conversion circuits to a primitive analog telephone (no dial or keys). Such devices operate normally in time division multiplex to process communication data between a computer (host) system and data link ports. The present adaptation includes a host programmable time division switch circuit within the control device, which can be conditioned dynamically to route digitized telephone signals directly between its data link and telephone ports, whereby telephone signals can be transmitted isochronally between a local user of the host system and a remote telephone, over a telephone network connection, while data signals are being transferred in either direction between the host system and equipment at the remote telephone station over the same connection.
