ABSTRACT:
An arrangement providing a monitor-on-hold feature for telephone station apparatus. The exemplary apparatus includes a handset transmitter and receiver, a speaker, and four user control buttons. A user is given the capability to move a connection for a first call from the handset to the speaker by simply actuating one of the buttons, the PRIVACY button. A connection is thereafter completed to the handset to answer a second call in privacy by actuating a second button, the NEWCALL button, while continuing to monitor the first call via the speaker. The capability to move connections is provided by a microprocessor-controlled switch included within the apparatus to selectively interconnect the two communications channels used for the two calls, with the handset and the speaker. Alternatively, the moving of connections is effected within the switching system serving the telephone station.
