3 If the conference card loop is disabled, enable it.
For an NT8D17 Conference/TDS Card, enter:
ENLX loop
(the conference loop is the odd loop of the conference/TDS loop pair)
Note: The conference/TDS card is not enabled automatically when it
is inserted. You must enable the card with the command ENLX. (This
command is used in LD 34 and LD 46 to address even loops and in LD
38 to address odd loops.) Enabling the loops with the command ENLL
does not enable the hardware for the card.
For other than an NT8D17 Conference/TDS Card, enter:
ENLL loop
(the conference loop must be an even loop for cards other than the
NT8D17)
If the system response is other than OK, see the X11 Administration
(553-3001-311) to analyze the messages.
4 Test the conference loop for channel, group, and switching faults:
CNFC loop
If the conference loop passes the tests, the output is OK.
If the system response is other than OK, see the X11 Administration
(553-3001-311) to analyze the messages.
5 Prepare the system for a manual conference call on a specified loop:
CNFC MAN loop c"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.
