Voice and Control Channel Local Loop Test (#13)
Note:
Note: S8300 / G700: This test aborts with Error Code 1412.
These tests check the information and control channels between the media server and the
Digital Line port circuit. The media server sends a message to loop around both the port’s
information and control channels.
1. First, the primary information (voice) channel’s loop-back test is run.
The test is performed by sending a digital count from the Tone-Clock circuit on the primary
information channel’s time slot and receiving the same digital count with a General-Purpose
Tone Detector.
2. While the primary information channel is still looped around, the Control Channel
Loop-Around test is run.
This test consists of sending four different transparent patterns to the on-board
microprocessor, receiving them back, and comparing them.
3. Then, the secondary information (data) channel’s loop-around test is run.
This is the same test as the primary information channel’s loop-around test and is
performed only if a DTDM is administered.
4. Next, a Conference test is run for the primary information channel.
This is the same test as Conference test (#6).
This 4-test sequence only generates one value (Pass, Fail, or Abort). If any test fails or aborts,
the sequence stops.

ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1000 ABRT System resources required to run this test are not available. The port may
be busy with a valid call.
1. Use display port location to determine the station extension or
attendant number of the port. Use status station or status
attendant to determine the service state of the port. If the port is in
use, wait until it is idle before testing. Attendants are always in use
(off-hook) if the handset is plugged in and the port is not busied out.
2. If the port status is idle, retry the command at 1-minute intervals up to 5
times.
