Call diversion device for coupling any telephone terminal - incorporates intermediate circuits in connecting lines between service user's terminals and analogue network

The diversion appts. couples desired terminals (A) called from a service user's terminal (B) to a replacement terminal (C), also usable for analogue network terminals. Two intermediate circuits (ZWE) are incorporated via two interfaces (SS1,2) each into the connecting lines from the service user's terminal to the analogue network. The first interfaces (SS1) are coupled to the telephone dial of the service user's exchange terminal, while the second interfaces (SS2) are coupled to the service user. The intermediate circuits having switching and memory components, and remote switching and control logic have at least a third interface (SS3). USE/ADVANTAGE - For telephone exchange operation. Rapid call diversion facility and evaluation of connection possibilities.
