Verifying the MGCP PRI Backhaul Configuration
SUMMARY STEPS
To verify the MGCP PRI backhaul configuration, complete the following steps.
1.
show isdn status
2.
show ccm-manager
3.
show ccm-manager backhaul
DETAILED STEPS
Step 1
show isdn status
Use the show isdn status command to verify connectivity.
In the following sample output, the Layer 2 protocol is Q.921, and the Layer 3 protocol is
CCM-MANAGER. This output verifies that the Layer 2 and Layer 3 protocols are configured to
backhaul ISDN. If you are connected to a live line, you should see Layer 1 status as active and Layer 2
as MULTIPLE_FRAME_ESTABLISHED.
Router#

L2 Protocol = Q.921 L3 Protocol(s) = CCM-MANAGER
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
NLCB:callid=0x0, callref=0x0, state=31, ces=0 event=0x0
NLCB:callid=0x0, callref=0x0, state=0, ces=1 event=0x0
0 Active Layer 3 Call(s)
Activated dsl 0 CCBs = 0
Number of active calls = 0
Number of available B-channels = 23
Step 10
isdn bind-L3 ccm-manager
Example:
Router(config-if)# isdn bind-L3 ccm-manager
Enables ISDN to backhaul Q.931.
Step 11
exit
Example:
Router(config-if)# exit
Exits interface configuration mode and returns to global
configuration mode.
