SS7-controlled Trunk Groups
When an SS7-controlled trunk group’s administrative state is set to out-of-service (OOS), the trunk
group cannot be used for outgoing calls; however, incoming calls on that trunk group are still honored.
• Trunk states are not changed.
• The operational state of that trunk group is not changed or affected.
If incoming and outgoing calls need to be blocked, then all trunks in that trunk group should be set OOS.
When the trunk group admin state is set to in service (INS), both incoming and outgoing calls can be
made and no trunk states are changed or affected.
Note Set COT, CVM, and CQM on the terminating gateway or switch to perform these tests. Otherwise, the
test (or tests) will fail.
To verify that all SS7 signaling links are in service, perform the following steps:
Step 1 Use the following control command to force an SS7-controlled trunk termination into the MAINT state
for testing:
control ss7-trunk-termination tgn-id=103; cic=13; mode=forced;
target-state=maint;
Step 2
Enter the command CLI> diag ss7-trunk-termination.
The following menu should be displayed:
Reply: Diagnostic SS7 Trunk Group Menu.
(1) SS7 MGCP Connectivity Test
(2) SS7 Termination Connection Test
(3) SS7 COT Test
(4) SS7 CQM Test
(5) SS7 CVT Test
(6) ALL
•
Test 1 tests if MGCP has access to the SS7 trunk termination.
• Test 2 tests if there is a path to the device (ping).
• Test 3 tests the integrity of the SS7 Bearer Path.
• Test 4 queries the SS7 circuit (or group of circuits) status. A range of CICs can be specified (to a
maximum of twenty four). Both remote and local trunk states are displayed in the results.
• Test 5 tests to ensure that each end of the circuit has sufficient and consistent information for using
the circuit in call connections. CLLI names are included.
• Test 6 performs tests 1 through 5.
Step 3 Select the test(s) you wish to run, the signaling trunk group id, the cic, and enter a command similar to
the following:
diag ss7-trunk-termination tgn-id=103; cic=13; test=1;
You should receive a response similar to the following:
TRUNK DIAGNOSTIC TEST EXECUTED -> diag trunk
TG-NUM -> 103
CIC -> 13
TEST-TYPE -> ADM-MGW-MGCP-CONNECTIVITY-TEST
