The facility may have a physical fault. Retrieve shelf or
MUX alarms to determine if there are alarms on the
appropriate facility that could adversely affect the DCC.
There may be an LAPD mode mismatch. Retrieve the
provisioning for both ends of the DCC and verify the
correct LAPD mode settings. The DCC data link layer
is not symmetric. One side of the link must be
configured for network and the other side must
configured for the user. If the equipment is a Fujitsu
FLM, set the Cmd/Resp parameter to “Network.”
