Type: Unsigned32

Access: read-only

Description: This is the PHY Link Channel (PLC) frequency. It is the center frequency of the lowest frequency subcarrier of the PLC. The aim of the PLC is for the CMTS to convey to the CM the physical properties of the OFDM channel.

What is docsIf31CmDsOfdmChanPlcFreq?

Reports, in Hz, the center frequency of the lowest-frequency subcarrier of this channel's PHY Link Channel (PLC), the special subcarrier group the CMTS uses to tell the modem the physical properties of the OFDM channel (such as profile and channel configuration). Admins can use this to locate the PLC in spectrum when correlating downstream OFDM sync issues with a specific frequency range.

Examples
