When there is an incoming call with reference to the same equipment number as one of the multiplex line 1A from the multiplex line 2A, the accommodation line portion 14a under setting a loop receives the incoming call and the communication test is done through a route for the communication test. When there is no accommodation line under setting the loop, the incoming call is rejected.

Abstract: A multiplexing system for ISDN circuits. Multiplexers in the system include data terminals, voice interfaces having voice trunks, high speed digital circuits and ISDN circuits, together with a control channel interface which connects trunking circuits by controlling calls on the control channel. When an outgoing voice call originates, data information from data terminals voice is multiplexed with compressed information from a voice interface and transmitted to trunking circuits. When calls originate, the control channel controls calls and connects them with trunking circuits. When using ISDN circuits, after setting up a communication channel for the circuits, a CPU controls calls to multiplex ISDN circuits on the control channel. By this structure decreasing the multiplexing ratio due to voice multiplexing call control on ISDN circuits can be eliminated when linking multiplexers with communication channels having high speed digital circuits and ISDN circuits.
