Hardware and Software
Constraining Factors
This section describes the constraining factors that limit the
capabilities supplied in the table above.
Calling Groups
Members of groups. QCCs cannot be members of calling groups
because the QCC position is set up as a system operator and has
its own queue that is different from the group’s queue.
Carriers
The first slot of the basic carrier is used for the processor module.
Coverage Groups
Senders per group. QCCs cannot be senders because they do not
have coverage available and use Position-Busy instead.
CTI Link
One CTI link is supported in Hybrid/PBX mode only.
Fax machines with Message-Waiting
The system can support more than 16 fax machines, but those in
excess of 16 cannot use fax message-waiting indication.
System Operator Consoles
DLCs. Two consoles are allowed for each MLX or analog module,
with a maximum of eight per system. Up to two DSSs can be
attached to an MLX operator console, and one is built into the
MERLIN II System Display Console.
QCCs. Two consoles are allowed for each MLX module with a
maximum of four per system.
