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.
Fiber means a glass strand or strands which is/are protected by a color coded buffer tube and which is/are used to transmit a communication signal along the glass strand in the form of pulses of light.
high voltage means the set of nominal voltage levels that are used in power systems for bulk transmission of electricity in the range of 44kV<Un 220 kV. [ SANS 1019];
PNode has the meaning set forth in the CAISO Tariff.
Integrated Digital Loop Carrier means a subscriber loop carrier system that is twenty-four (24) local Loop transmission paths combined into a 1.544 Mbps digital signal which integrates within the switch at a DS1 level.
