FIELD: processing technology. SUBSTANCE: proposed gear to process calls in remote subscriber's module of electron commutation system is related to communication systems in which remote subscriber's module is connected to main switching center by means of connecting communication line. Gear to process calls includes interface with subscriber's line which has functions of reception of phone number and function of tone signals and can process calls between in-house subscribers of remote subscriber's module even if connecting communication line between main switching center and remote subscriber's module is out of order and processor of remote subscriber's module to receive and analyze phone number, to send required tone signals, to transmit and receive special digital information that functions as processor of access commutation of main switching center if connecting communication line between main switching center and remote subscriber's module is out of order. EFFECT: development of reliable gear and method to process calls in remote subscriber's module of electron commutation system. 8 cl, 9 dwg
