Installing Plug-in Modules
Two modem modules (PSTN or GSM) may be installed on the Controller board to
increase functionality. Figure 24 shows the two slots available for each modem
module, the primary (left) slot and the back-up (right) slot.
If both modem slots are available, always install the plug-in module in the primary
slot; the system always attempts to make PSTN or GSM calls on a modem
installed on the primary slot before attempting to use the back-up slot.
