PURPOSE:To make it possible to change the sending trunk route selected by the transmission by the same access number by providing a means for temporalily changing the detour route selection logic of a transmitter. CONSTITUTION:When the extension A dials to make a call for transmission, the dialed number is received by a transmitting resister trunk ORT and analyzed at a central control unit CC. The unit CC selects the transmitting trunk route from a detour route pattern when the pattern 1 of the detour route pattern is set by an attendant board and the extension A transmits from a trunk TRK1 included in the detour route pattern 1. When the detour route pattern is set at the attendant board to the pattern 2, the unit CC selects the transmitting trunk route from the detour route pattern 2 and the extension A transmits from the trunk TRK2 included in the detour trunk route 2. |
