Description: The associated port for the ISDN D-channel. dchanzero : Both B channels have access type Permanent.

What is isgVGIsdnCfgDChanPort?

Selects which physical port carries the ISDN D-channel signaling traffic, with special values indicating both B-channels are permanent (no D-channel data) or that packet data rides the D-channel on port 1 or port 4. An admin sets this to match how the ISDN line was provisioned by the carrier, and the 'nc' value skips D-channel port configuration entirely.
