ABSTRACT:
Subscriber's interface enabling the connection of otherwise incompatible telephone device systems (hereinafter "(Z)") to a single telephone line, each telephone device system having devices such as: a computer modem (hereinafter "(F)"), an automatic answering machine (hereinafter "(A)"), and telephone sets (hereinafter "(T)"). When a ring signal is received from the central office, the interface allows a first device, such as (A) or (T) to answer the call, and monitors the communication between the calling party and the first device bearing in mind its various operating modes. Based on the monitored conversation, the interface determines if the call should be connected to a second device, such as (F). If so, an actuating signal is sent to (F), whereupon when (F) becomes OFF HOOK, it is connected to the telephone line. If the first device is an automatic answering machine, its various operating modes include: outgoing message, incoming message, beeperless remote mode. If the first device is a remotely located telephone set, its various modes of operation include simple human voice signals and complex human voice signals.
