27、 Free Trade Association. PD CLC/TS 50590:2015CLC/TS 50590:2015 - 6 - 1 Scope This Technical Specification specifies the physical layer, medium access control layer and logical link control layer for communication on an electrical distribution network between a master node and one or more slave nodes
28、 using a compatibly extendable form (CX1) of Adaptive Multi-Carrier Spread Spectrum (AMC-SS) technique. The adaptive cellular communication network technology provided in this specification may be used for automated meter reading as well as for other distribution network applications. TheGK1 physica
29、l layer provides a modulation technique that efficiently utilizes the allowed bandwidth within the CENELEC A band (3 kHz 95 kHz), offering a very robust communication in the presence of narrowband interference, impulsive noise, and frequency selective attenuation. The physical layer of AMC-SS is def
30、ined in Clause 5 of CLC/TS 50590:2015GK2. The data link (DL) layer consists of three parts, the Medium Access Control (MAC) sub-layer, the Logical Link Control (LLC) sub-layer and the Convergence sub-layer. The data link layer allows the transmission of data frames through the use of the power line
31、physical channel. It provides data services, frame integrity control, routing, registration, multiple access, and cell change functionality. The MAC sub-layer and the LLC sub-layer of AMC-SS are defined in Clause 6 of CLC/TS 50590:2015. The Convergence sub-layer is defined in this document. 2 Normat
