Conference cards

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.

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.
