FIELD: devices for communications. SUBSTANCE: device has n primary commutation units 1÷1, n secondary commutation units 2÷2, additional commutation unit 3, unit 4 for information storage and output. Device may be used in design of automatic commutation units and electronic exchange systems of low and middle capacity. EFFECT: decreased number of interlocks, when connection is established between non-priority users, possibility of connection between priority users almost without interlock, increased functional capabilities due to possibility of access to database. 1 dwg |
