1030 35 * description : The purpose and function of the AT_CONNECTOR is mainly to
1040 36 * run the protocol with an AT. The ATC is the master of
1050 37 * this communication.
1060 38 * The state of the transmission line is monitored by ATC
1070 39 * and alarms concerning the conditions of transmission are
1080 40 * signalled to PAC or DC.
1090 41 * Furthermore commands originating from DC and AC are executed
1100 42 * and alarms from AT are signalled to an AC.
1110 43 * AT_CONNECTOR participates in the module supervision in
1120 44 * the TS.
