PURPOSE:To make good service possible to reduce the load of the operator by controlling insertion of the receiving amplifier automatically by the translator output at a transmission time and controlling it manually at a receiving time in PBX. CONSTITUTION:When the operator of attendant board ATT performs transmission connection to the line wire and translator TLR converts other-party station information, amplifier circuit AMP switching information dependent upon long distance line information is transferred to ATT. Therefore, amplifier unit AMPU is inserted and connected to receiver R, which is connected to circuit network N, automatically. At a receiving time from the long distance line wire, the amplifier is inserted and connected by an arbitrary manual operation of the ATT operator. |
