Call to Subscriber under Test
This section provides example steps to use the feature for NTE NCT 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.
Perform the Following Command or Action:
Step 1
add destination dest-id=nlb-line-test;
call-type=test-call; call-subtype=nct-line-test;
Step 2
add dial plan id=<xxx>; digit-string=552;
dest-id=nlb-line-test; split-npa=none;
del-digits=0; min-digits=13; max-digits=13;
noa=national;
Where <xxx> is an existing dial plan. The dial
Note
plan id must match to the LB test prefix (for
example 552) in the digit string.
Step 3
add ca-config type=nlb-test-service-affecting=n;
datatype=boolean;value=n;
Step 4
change mgw-profile id=isdnNLB;
parallel-test-conn-supp=y;

Verify the Billing call type.

Trunk Loopback Tests over an ISDN Trunk

For trunk loopback testing when the test call and normal call are on the same circuit, the normal call
always has precedence. For example:
1.
2.
OL-8723-19
From the test equipment, dial the NTE NLB-LINE test call (552+xxx-xxx-xxxx). The BCM does
not notify the Feature Server of this call and the call is looped back.
Take the subscriber under test off-hook. There is a dial tone.
Call the subscriber under test from another subscriber. Call is set up, and the test call stays up.
if the test call is on circuit xxx and a normal call comes in on the same circuit, then the normal call
is set up and the test call is released.
if a normal call is on circuit xxx and a test call comes in on same circuit, then the normal call stays
up and the test call is released.
Purpose
Provision the Destination table.
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
Table" section.
Provision the Call Agent Configuration table with
service affecting off.
Turn on support parallel test connection in the Media
Gateway Profile table.
