1 Scope

This part of GB/T 17215.6 specifies a data link layer for connection-oriented, HDLC-based, asynchronous communication protocol sets. To ensure a consistent data link layer service specification for both connection-oriented and connection-free operation, the data link layer is divided into two Sublayer. logical link control sublayer (LLCsub-layer) and medium access control sublayer (MACsub-layer). This section supports the following communication environments. ---Point-to-point and point-to-multipoint configuration; --- Dedicated and switched data transmission equipment; ---Half duplex and full duplex connection; --- Asynchronous start/stop transmission, 1 start bit, 8 data bits, no parity, 1 stop bit. At the same time, the following two special procedures are defined. --- The separately received service user layer PDU part is transmitted from the server side to the client in a transparent manner. Server side service The user layer can send its PDU to the data link layer in fragmented form, and the data link layer can hide the fragment for the client side; --- An event report by sending a UI frame from the slave to the primary station. Appendix B explains the role of data models and protocols for data exchange in electricity meters.
