Run any additional tests that might be needed to determine that all SS7 signaling links are reachable and
in service.
ISDN-controlled Trunk Groups
When an ISDN-controlled trunk group’s administrative state is set to out-of-service (OOS), D channels
corresponding to the trunk group are disconnected.
Operational state of all trunks in the trunk group are set to locally blocked, which overwrites any
other states of trunks in that trunk group prior to the trunk group going out-of-service
The trunk group cannot be used for outgoing calls and incoming calls cannot be received because
the D channel is down.
When an ISDN-controlled trunk group is set to in-service (INS), all trunks in the trunk group are brought
in-service and both incoming and outgoing calls are allowed.
The original state of some of the trunks prior to the trunk group going out-of-service might not be
recovered when the trunk group goes back in-service and might have to be restored manually.
To verify that all ISDN-controlled trunk terminations are in service, perform the following steps:
Step 1 Use the following control command to force an ISDN-controlled trunk termination into the MAINT
state for testing:
control isdn-trunk-termination tgn-id=17; cic=1; mode=forced;
target-state=maint;
Step 2
Enter the command CLI> diag isdn-trunk-termination.
The following menu should be displayed:
Reply: Diagnostic ISDN Trunk Group Menu.
(1) ISDN MGCP Connectivity Test
(2) ISDN Termination Connection Test
(3) ALL
Test 1 tests MGCP access to the ISDN-controlled trunk termination, test 2 determines if there is a path
to the device by pinging it, and test 3 performs both tests 1 and 2.
Step 3 To perform test 1 on ISDN trunk group 17, enter the following command:
diag isdn-trunk-termination test=1; tgn-id=17; cic=1;
You should receive a response similar to the following example:
TRUNK DIAGNOSTIC TEST EXECUTED -> diag trunk
TG-NUM -> 17
CIC -> 1
TEST-TYPE -> ADM-MGW-MGCP-CONNECTIVITY-TEST
TEST-DURATION -> 0
RESULT -> TEST-SUCCESS
REASON -> PASSED: Reason: AUEP-NACK received with RespCode = 510
Reply: Diagnostic command executed.
Step 4
To perform test 2 on ISDN trunk group 17 , enter the following command:
diag isdn-trunk-termination test=2; tgn-id=17; cic=1;
