Provisioning BRI and PRI lines
This section discusses how you put BRI and PRI lines into and 
out of service.
BRI and T1 lines
Provisioning applies to BRI and T1 loops and lines. It allows 
you to place loops and lines in or out of service, either before 
or after the BRI Cards have been installed in the ICS.
When you provision a loop, ISDN terminals on the loop can be 
used to make outgoing calls or receive incoming calls...

If the loop is configured as a U-NT, T or S loop, press 
≠ and  ‘ to display the individual lines. 
There are no lines associated with an S or U-LT loop.
1. Press REMOVE
 to take the line out of service.
2. If line is busy, the display will ask if you still want to 
remove it from service. Press YES
 to go ahead.

Deprovisioning a line
Deprovisioning all of the lines on a DTI does not disable the 
cartridge.
Disabling a PRI Channel
PRI channels can be disabled. However, there is no association 
between a line number and a b-channel. Disabling a b-channel 
can be done when you have fractional PRI. See Fractional PRI 
on page 540.

Tests
Norstar allows you to run tests which verify the integrity of the 
installation wiring for the telephones. 
In addition, you can evaluate the transmission quality of a BRI 
loop through your service provider using a loopback test to 
evaluate different aspects and segments of the T1 digital 
transmission path. You can only run one loopback test at a 
time on any one DTI.

Line loopback
The line loopback test loops the full 1.544 Mbps signal 
received from the network back to the network. The looped 
signal is regenerated without any change in the framing format 
and without the removal of any bipolar violations. The line 
loopback test can also be invoked and stopped remotely using 
the in-band signal or via the facility data link (FDL) in 
extended super frame (ESF) format.
The line loopback test must be run in...

Payload loopback
The payload loopback test loops the received information bits 
(192 per frame) back to the network. The payload loopback 
test can also be invoked and stopped remotely via the facility 
data link (FDL) in extended super frame (ESF) format. 
The payload loopback test must be run in coordination with the 
T1 service provider. Some test patterns can cause the DTI to 
reset. To avoid this, start the payload loopback test from your...

Card edge loopback
The card edge loopback test loops the outgoing signal on the 
DTI back to its internal received signal path. Signal paths to 
the external network are disconnected.

The continuity loopback test shorts the tip and ring pair of the 
receive signal path with the transmit signal path. This test 
allows you to check the metallic continuity of the external 
wiring.
Tests initiated from Norstar
You can start and stop Loopback tests in Maintenance 
programming under the heading Loopback tests. You can 
also push a button on the DTI faceplate to start and stop the 
continuity test.
You can run DTE and DS30 Loopback...
