Programming Procedures
Primary Operator Positions
The primary operator position is the position to which your call is directed when
you dial 0 on a System Access button.
The first jack on the first MLX module in your system is assigned as the primary
operator position.
If your system has QCC operator positions, this position must be changed from
the factory setting (DLC) to a QCC operator position. (The position of the
primary operator cannot be changed from the first jack on the first MLX
module.)
QCC System Operator Positions
This procedure applies to Hybrid/PBX systems only. Note that both QCC and
DLC operator positions can be assigned with this procedure, although its
primary purpose is to assign QCC operator positions.
QCC operators serve as central answering positions for all incoming calls.
Incoming calls are held in the QCC queue and are directed to each QCC
operator in a prioritized sequence. The calls are received one at a time,
regardless of the number of incoming calls to the system.
Additional QCC operator positions can be assigned only to the first and fifth
jacks of MLX modules. A maximum of four QCC operator positions can be
assigned. Use this procedure to specify QCC operator positions that serve as
central answering positions for all incoming calls.
CAUTION:
If you want to add or remove QCC operator positions, the following
conditions apply:
