Abstract

PURPOSE:To set camp-on of extensions allocated different PBXs, by setting the camp-on to a called extension with the operation of an extension of a calling PBX when the extension of a called PBX is busy. CONSTITUTION:An extension STA-A dials an access code for an exclusive line and dials an extesion number of an extension STA-B after listening the dial tone from a private branch of exchange PBX-B. When the STA is busy, hooking operation is made with the STA-A, a camp-on set code between the PBXs is dialed and the STA waits for the response with on-hook when the camp-on set completion tone from the PBX-B is heard. When the STA-B is vacant, the connection for the camp-on callback can be made to the STA-A.
