Loop Concentrator/Multiplexer or "LCM" is the Network Element that does one or more of the following: aggregates lower bit rate or bandwidth signals to higher bit rate or bandwidth signals (multiplexing); disaggregates higher bit rate or bandwidth signals to lower bit rate or bandwidth signals (demultiplexing); aggregates a specified number of signals or channels to fewer channels (concentrating); performs signal conversion, including encoding of signals (e.g., analog to digital and digital to analog signal conversion); or in some instances performs electrical to optical (E/O) conversion. LCM includes DLC, and D4 channel banks and may be located in Remote Terminals or Central Offices.
