In the old plan, the RTU information at the substation end first needs to go through a modem and be connected to the 2/4-line EM interface of the PCM equipment. TK457V050 3BSE004394R1 is transmitted to the PCM equipment at the central station through the SDH network and restored to the 2/4EM interface. After passing through the distribution frame, it extends from the communication room to the automation room and is restored to low-speed data by the modem. Several low-speed data paths are connected to the IOLAN equipment, which is converted into IP packets and sent to the front-end machine.

Through the schematic analysis of the new and old schemes, it can be seen that TK457V050 3BSE004394R1 not only saves a lot of equipment investment (including PCM equipment, modems, IOLAN devices), but also simplifies the wiring management of the line, realizes end-to-end digitization of data, and effectively improves the quality and reliability of data transmission while completing the same function.

In the new networking solution, a new type of serial port server is applied. TK457V050 3BSE004394R1 is different from previous IOLAN devices in that it can directly convert the data carried by each time slot in the E1 signal to IP packets. In the upstream direction: the device can extract the effective data carried in the E1 time slot and convert it into corresponding IP packets to send to the front-end machine; In the downlink direction, the device can receive IP packets sent by the front-end processor and insert the data in the IP packet into the corresponding E1 circuit in the time slot.
