The advantage of programming the system with a PC is that all programming
can be backed up on a floppy or hard disk. This makes recovery of system
programming fast and effortless in the event of an inadvertent system shutdown
or loss of power.
Note: Programming with a PC is recommended for systems operating in the
Hybrid/PBX mode because of these backup and restore capabilities.
To program with a PC, the SPM software is needed along with MS-DOS* or
®
UNIX operating system software. SPM software provides interface to the
programming and maintenance software in the control unit processor module.
The SPM software emulates the display screen and buttons of a system
programming console (the MLX-20L telephone). As shown in Figure 2-16, the
SPM display mirrors the following three areas of the console:
Display and display buttons (at the top of the SPM screen).
Function buttons (described on the right side of the screen).
Line buttons (mirrored in the lower portion of the display.)
To use SPM for system programming, the PC must be connected to the control
unit. This can be done either directly through the system programming jack on
the control unit, or through a modem (modems can be used for either on-site or
remote programming).
