cadIfDsOfdmChlPlcLowSubcCentFreq
Module: CADANT-CMTS-DOWNCHANNEL-MIB
OID (symbolic): CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDsOfdmChlPlcLowSubcCentFreq
OID (numeric): 1.3.6.1.4.1.4998.1.1.15.2.5.1.21
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The center frequency of the lowest frequency subcarrier of the PLC itself. By definition, this is 2.8 MHz higher than cadIfDsOfdmChlPlcBlkLowSubcCentFreq (i.e., the PLC block is 6 MHz, and the 400 KHz PLC is centered in that block).
What is cadIfDsOfdmChlPlcLowSubcCentFreq?
Reports the center frequency of the lowest subcarrier within the Physical Layer Control (PLC) channel itself, which by definition sits 2.8 MHz above the start of the 6 MHz PLC block. This read-only value confirms the precise placement of the PLC within the OFDM spectrum.
