to the lower RS-232 port on the processor module
the built-in modem in the processor module, which permits remote
programming via the public network. (For example, the AT&T support
personnel can access the system by using a PC with a modem and with SPM
software; AT&T support personnel call the system and enter a password to
gain access. The system must be programmed for Remote Access.)
