Instruction manual
Features
MS-DOS® or UNIX operating system software. SPM provides an 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 31, 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 (represented 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). See System Programming for details on SPM use.

On-Site and Remote Programming. PC-based SPM programming via a modem
can be done either on-site or from a remote location. In both cases, the built-in
modem of the control unit is used. Accessing the modem for on-site
programming is done by dialing the code for the control unit’s modem (*10),
which establishes connection to the system programming jack.
Accessing the built-in modem for remote programming can be done in any of
the following ways:
■ Calling the system on a remote-access line and entering a barrier code
(if needed), and then dialing the code for the control unit’s built-in
modem.
