40、nvironments The DLMS/COSEM PLC AMC-SS communication profile is intended for remote data exchange on Neighbourhood Networks (NN) between Neighbourhood Network Access Points (NNAP) and Local Network Access Points (LNAPs) or End Devices using AMC-SS technology over the low voltage electricity distribut

42、er application functionsFigure 1 Communication architecture End devices typically electricity meters comprise application functions and communication functions. They may be connected directly to the NNAP via the C interface, or to an LNAP via an M interface, while the LNAP is connected to the NNAP v

43、ia the C interface. The LNAP function may be co-located with the metering functions. A NNAP comprises gateway functions and it may comprise concentrator functions. Upstream, it is connected to the Metering Head End System (HES) using suitable communication media and protocols. End devices and LNAPs

44、may communicate to different NNAPs, but to one NNAP only at a time. From the PLC communication point of view, the NNAP acts as the master node while end devices and LNAPs act as slave nodes. NNAPs and similarly LNAPs may communicate to each other, but this is out of the scope of this specification,

45、which covers the C interface only. When the NNAP has concentrator functions, it acts as a DLMS/COSEM client. When the NNAP has gateway functionality only, then the HES plays the role of a DLMS/COSEM client. The end devices or the LNAPs play the role of DLMS/COSEM servers. PD CLC/TS 52056-8-7:2015 9

48、is used; the IPv4 or the IPv6 network layer, if IP transport is used; the AMC-SS Data link layer, which consists of the Convergence, LLC and MAC sub-layers; the AMC-SS Physical layer.

49、HY) 6.1 Overview main features and functions This layer provides the interface between the equipment and the physical transmission medium that is the low-voltage distribution network. It transmits and receives MPDUs between neighbour nodes. The AMC-SS PHY uses a fast frequency-hopping spread spectrum technique combined with Differential Phase Shift Keying (DPSK) and forward error-correcting coding. Three
