This read-only enumerated value reports the transmit state of the channel on the internal cellbus side in the ingress direction, indicating whether cells are being forwarded normally into the switch fabric or an AIS/FERF condition is being signaled internally instead, mirroring commonChanIngrXmtState. Admins use it to trace internal alarm propagation on the cellbus-facing side of the ingress path, distinct from the external line-facing state. For example, a channel showing sendingFerf here (rather than on the line side) would point to an internally detected condition being signaled toward the switch fabric.
