Prepare the system for a manual conference call on a specified loop:
CNFC MAN loop c
Where “c” is the manual conference group (1-15)
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 will enter the manual conference call. The
prime directory number (PDN) indicator, if equipped, will light on each
telephone.
