ISDN Network Loopback Test
NLB Line Loopback Test over an ISDN Trunk with Service Affecting Turned Off and Parallel Test Connection Support Turned On:
Call to Subscriber under Test
This section provides example steps to use the feature for NTE NLB line test over an ISDN trunk with
service affecting turned off and parallel test connection support turned on; call is to the subscriber under
test.
Then:
1.
From the test equipment, dial the NTE NLB-LINE test call (551+xxx-xxx-xxxx). The BCM does
not notify the Feature Server of this call and the call is looped back.
2.
Take the subscriber under test off-hook. There is a dial tone.
3.
Call the subscriber under test from another subscriber. Call is set up, and the test call stays up.
4.
Verify the Billing call type.
NCT Tests
This section provides examples of line loopback network continuity tests (NCT) over ISDN.
Perform the Following Command or Action:
Purpose
Step 1
add destination dest-id=nlb-line-test;
call-type=test-call; call-subtype=nlb-line-test;
Provision the Destination table.
Step 2
add dial plan id=<xxx>; digit-string=551;
dest-id=nlb-line-test; split-npa=none;
del-digits=0; min-digits=13; max-digits=13;
noa=national;
Note
Where <xxx> is an existing dial plan. The dial
plan id must match to the LB test prefix (for
example 551) in the digit string.
Provision the Dial Plan table. The digit-string plus the
min-digits and max-digits total depends on the settings
configured (if any) in the
section.
Step 3
add ca-config type=nlb-test-service-affecting=n;
datatype=boolean;value=n;
Provision the Call Agent Configuration table with
service affecting off.
Step 4
change mgw-profile id=isdnNLB;
parallel-test-conn-supp=y;
Turn on support parallel test connection in the Media
Gateway Profile table.
