1 Scope
This Technical Specification specifies the DLMS/COSEM communication profile using a
compatibly-extendable form (CX1) of Adaptive Multi-Carrier Spread-Spectrum (AMC-SS) PLC
for neighbourhood networks. Its structure is in line with the DLMS/COSEM framework as
described in EN 62056-1-0[GK1].
The transport layer, the application layer and the data model are as specified in the EN 62056
DLMS/COSEM suite.
