3.13.12 Control and management (see 4.7.16) The equipment has a packet switching module (TPX-B) for the transmission and population processing of network control information. It can provide the entry function of the node switch packet switching module (TPX-A) for the first and second level network control center equipment, FC and local packet terminal modules. When the port of the device is interconnected with the trunk node switch, the two machines should automatically establish the interconnection dedicated line between TPX-A in the trunk node switch and TPX-B of the device in the first voice channel time slot after the handshake process. If the dedicated line between TPX-A and TPX-B has been established on the first voice channel of the interconnection port between the trunk node switch and the device, the network control device can realize the control of the device. The main control contents are: main working data; b. Traffic statistics; real-time working status data: d. Port remote alarm data, such as protocol, synchronization, identification, transmission and equipment alarm information. The device can manage the multiplexer.
