Abstract
An arrangement is disclosed for providing trunk consultation in an electronic private automatic branch exchange which is built around a space divided solid state matrix. The trunk consultation arrangement is enabled by a hookswitch flash from a consulting PABX station connected to an established incoming or outgoing trunk call and directs the trunk junctor associated with that call to place the connected trunk on hold. While the connected trunk junctor is in a held status, the consulting PABX station is forwarded to a local junctor where the consulted trunk party is dialed. A connection between the consulting PABX station and the consulted trunk party is then established via a second trunk junctor. Further circuitry is provided in the trunk consultation arrangement to establish a three-way consultation between the consulting PABX station, the consulted trunk party, and the held trunk party.
