To acquire anything, it MUST acquire a primary downstream channel. That is the listener of first resort and then a sequence of interactions with the CMTS takes place leading to the acquisition of a bonded channel group.

If that doesn't happen but everything else is "alright" you can function on the primary channel alone.

Whatever, though, the situation is unacceptable and you should call it in on 0800 0520431.
