Note: E10 is the same variant as 5ESS.

#### Details

For the DMS variant, the receipt of a RESTART message for a single B channel resets the status of that B channel to in-service. A RESTART message for the entire interface resets the status of all the B channels on that trunk to in-service.

If type is set to PREFERENCE_TRUNK, ignore the BChannel field.
