MERLIN LEGEND Communications System Release 5.0
System Planning 555-650-112
2 Control Unit Configuration
Recording System Operating Conditions
NOTES:
1. In conjunction with the MLX-20L telephone and the PC, a Personal
Computer Memory Card International Association (PCMCIA) card is
required Release 3.0 and later of the communications system. Check the
box labeled PCMCIA Memory Card.
2. In addition to being factory-set for system programming, the first (lowest)
extension jack on the first MLX module is also factory-set as the primary
operator position. Since the primary operator position cannot be
reassigned to another extension jack, you may want to change the
system programming assignment to ensure that future programming
sessions do not interfere with the operators work.
2. To change the factory-set system programming jack, write in the new
logical ID using the information from the Control Unit Diagram.
If you want the system programming jack to be different from that of system
operators, change the programming assignment to any one of extension jacks 2
through 5 on the first MLX module in the control unit (the lowest jack on the
module is extension jack 1). You fill in the extension number of the jack later.

System Mode

The mode of operation determines how outside lines/trunks are provided to users,
the types of operator consoles allowed, the features available, and how they work.
Each system is registered with the Federal Communications Commission (FCC)
to operate as a Private Branch Exchange (PBX), Hybrid, or Key system (factory
setting). However, you can program the system to operate in any of the three
modes: Hybrid/PBX, Key, or Behind Switch.
Planning Form Instructions
Under the System Mode heading in the System Operating Conditions section of
Form 1 (page 2), check one of the following:
If the system will operate in Key mode, check Key. (This is the factory
setting.) If need be, this mode can be changed to Hybrid/PBX mode at
another time.
If the system will operate in Hybrid/PBX mode, check Hybrid/PBX.
If the system will be connected behind a larger system or a Centrex
system, check Behind Switch and record the hosts dial codes for the
Transfer, Conference, and Drop features so users can access these
features on the larger system.
If you check Permanent Key, the switch in the back of the processor
module must be placed in the Permanent Key position. The switch cannot
be changed without changing the FCC registration of the system.
