Nortel Networks Circuit Card 311 - Manual (Page 73)

Conference cards 73
CNFC MAN loop c
Where "c" is the manual conference group (1-15)
A manual conference test is performed by stepping through
conference channels and groups, listening for noise that indicates a
faulty card.
The manual conference test can be performed through a system
terminal or BCS maintenance telephone. If commands are entered
from a maintenance telephone, this telephone automatically
becomes part of the manual conference call.
Only one manual conference call is allowed at one time. A manual
conference consists of only two telephones, where one telephone
acts as a signal source while the other acts as a listening monitor.
After you enter the CNFC command, any two telephones (one may
already be the maintenance telephone) dialing the special service
prefix code (SPRE) and the digits 93 enters the manual conference
call. The prime directory number (PDN) indicator, if equipped, lights
on each telephone.
Going on-hook takes the telephone out of the manual conference
call, and the test must be restarted.
See LD 38 in Software Input/Output Reference — Administration
(NN43001-611)
for more detailed information on using this command.
6 Test various channels and conference groups audibly with the
command
CNFC STEP
When stepping through channels and groups, a clicking followed by
silence is normal. Any distortion or other noises indicates a faulty
card.
Once the CNFC STEP command has been entered, entering C on
the system terminal or maintenance telephone steps through the
conference channels. Entering G steps through the conference
groups. There are 15 channels per group and 15 groups per
conference card.
Entering an asterisk (*) and END stops the test.
Again, see "LD 38" in the Software Input/Output Reference —
Maintenance (NN43001-711) for detailed information on using this
command.
