A logical channel setting system is applied to an asynchronous transfer mode (ATM) network which is coupled to terminal equipments which are in conformance with a high performance parallel interface (HIPPI) via respective terminal adapters which are in conformance with the HIPPI. The logical channel setting system includes a call part, provided in a transmitting terminal adapter, for setting a logical channel in the ATM network in response to a request signal which is ON and is received from a transmitting terminal equipment which is coupled to the transmitting terminal adapter, and a disconnect part, provided in the transmitting terminal adapter, for releasing the logical channel which is previously set in the ATM network in response to a request signal which is OFF and is received from the transmitting terminal equipment which is coupled to the transmitting terminal adapter.
