System Description
System Operator Consoles
System operator consoles are telephones that are programmed
for call handling and other operator duties.
Two configurations of operator consoles can be used—direct-
line console (DLC) and queued call console (QCC). In a DLC
configuration, lines/trunks are assigned to individual buttons and
the console can have several calls ringing at the same time. In a
QCC configuration, incoming calls are held in a queue and calls
are directed to, a QCC as a position becomes available. Only one
call rings at a time.
The following telephones can function as DLCs:
MLX-20L telephone*
MLX-28D telephone*
MERLIN II System Display Console with built-in DSS
BIS-34D
BIS-34
BIS-22D
Note: In a Hybrid/PBX system, only the MLX-20L telephone can
function as a QCC.
DLCS are connected either to an analog station jack on a 008 or
408 analog multiline telephone module or to a digital station jack
on a 008 MLX module. QCCs must be connected to a digital
station jack on a 008 MLX module. The QCC system operator
console must be connected to the first jack on the first 008 MLX
module.
* One or two DSS adjuncts can be added to provide 50 or 100
additional extension buttons.
