Abstract
Abstract A remotely controlled telephone operator simulator includes a microprocessor control circuit for supplying digitally recorded voice messages and non-voice messages, as initial "answers" to an incoming telephone call, which is automatically "call forwarded" to a remote telephone set. When the call is received at the remote telephone set, the user supplies tone signals back to the initial called line. Duplexer circuits and a two-input multiplex circuit are provided to prevent these tone signals from being heard by the calling party on the first line. The tone signals, however, do cause operation of the microprocessor control circuit, to cause selected ones of the voice and non-voice messages to be supplied through the multiplex circuit to the calling line. After the desired number of these stored messages are supplied, the microprocessor control circuit switches the multiplex circuit from response to the stored messages to "live" outgoing conversation from the second telephone line. Normal two-way telephone conversation takes place between the called party and the calling party during the remainder of the call.
