Hardware Components
Forced Release: Disconnects the system operator from an active call
and makes the system operator available to receive another call.
Each QCC can have one or two DSSs attached. The system operator can use
the buttons during call handling, for example, to extend a call, make an inside
call, park a call, or see the availability of an extension.
No more than four QCCs are allowed on a system. A maximum of two QCCs
can be assigned on each 008 MLX or 408 GS/LS-MLX module (Release 2.0
only). No more than eight system operator positions of any combination (QCC
and DLC) are allowed; when used in combination, no more than four can be
QCCs.
When a system has QCCs, the first MLX module used for QCCs must be
installed in the control unit to the left of any other type of module with station
jacks.
A maximum of two QCCs is allowed per 008 or 408 MLX module. A QCC can
be connected only on the first and fifth station jack on each module.
The following options must be assigned to a QCC through system
programming:
QCC operator receiving calls
QCC Queue Priority
Call Types
Elevate Priority
Hold Return
Automatic Hold or Automatic Release
Calls-In-Queue Alert
Queue Over Threshold
Extended Call Completion
Position Busy Backup
Return Ring Interval
Message Center Operation
Direct-Line Consoles
In a DLC configuration, lines/trunks are assigned to individual buttons and the
console can have several calls ringing at the same time.
A DLC operates like other multiline telephones. In all three modes of operation
(Key, Hybrid/PBX, and Behind Switch), outside lines are assigned as personal
lines to individual buttons on the console. The lines assigned on an individual
DLC can also be assigned to buttons on other consoles or other telephones.
Incoming calls can ring on any of the line buttons, and several calls can ring
simultaneously. The system operator directs calls to other users via the
Transfer button.
