CAUTION:
This section is intended solely as an overview of the application. For
comprehensive information about the use of the application, see the
documentation for the product.
SPM is a software application used for programming and maintenance of the
system. It performs the same functions as an MLX-20L telephone used as a
system programming console, providing a display that emulates the console
display. SPM also has additional features, such as the ability to back up and
restore system programming and to print reports.
Two versions of SPM are available:
SPM standalone, running on an approved AT&T DOS PC
SPM Integrated with IS Ill
A PC with DOS-based SPM can be connected directly to the control unit or can
access the system remotely in one of the following ways:
The system programmer dials the system directly. A password can be
set up to prevent unauthorized access.
The system programmer dials the system operator and asks to be
transferred to the system's built-in modem (Dial Code *IO).
SPM—IS Ill can be used only through a direct local connection,
SPM can be programmed to operate in English, French, or Spanish for
communication with the control unit. Independent of this language setting, an
on-screen option allows the programmer to select from the same three
languages for the console-simulation window only for the duration of the current
session.
Considerations and Constraints
SPM must be upgraded to version 2.
communications system.
Unless the system is being backed up or restored, a remote SPM
connection takes priority over a local user. If the local user is
programming when a remote user connects to the system, the system
sends a warning message to the local user and disconnects him or her.
A PC running DOS-based SPM connects to the lower RS-232 jack on the
processor module of the control unit. This connection runs at 1200 or
2400 bps with autobaud.
