What is docsDrfChannelBlockNumberChannels?

This Unsigned32 value reports the number of QAM channels (N) that can physically be transmitted from a given channel block on the M-CMTS. An admin uses this read-only value to know the hardware ceiling for docsDrfChannelBlockCfgNumberChannels before attempting to configure how many channels are actually active. A channel block reporting N=8 means up to 8 QAM channels can be transmitted from that RF connector, even if fewer are currently configured.
