Record the following system operating conditions:
programming equipment that will

whether Automatic Maintenance Busy is enabled
a reminder to set the system time and date
Use the "Control Unit Diagram" on PBX System Form 1 as a reference and
mark the "System Operating Conditions" section of that form.
Two types of equipment can be used for system programming:
an MLX-20L telephone acting as a system programming console. The
telephone is the first (lowest) station jack on the first MLX module and is
factory set for system programming.
a personal computer (PC) with MERLIN LEGEND System Programming and
Maintenance (SPM) software. (Both DOS- and UNIX†-based SPM are
available.) The PC is connected to the lower jack on the processor module.
Planning Form Instructions
Under the heading, "System Programming Console," on Form 1:
1 .
Do one of the following:
Check "No" if you are using a PC with SPM to program the system. Go to
the "Mode of Operation" instructions.
Enter the Logical ID and Extension Number if you are using a system
programming console.
2 .
To change the factory-set system programming jack, write in the new
logical ID (using the information from the "Control Unit Diagram").
Note:
You will fill in the extension number of the jack later.
In addition to being factory set for system programming, the first (lowest) station
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 station
jack, you may want to change the system programming assignment to ensure
that future programming sessions do not interfere with the operator's work.
If you want the system programming jack to be different from that of a system
operator, change the programming assignment to any one of station jacks 2
through 5 on the first MLX module in the control unit.
