Where an Alarm panel does not support a serial/data bus connection but a modem/digi is available, the SPT can be equipped with a Modem Capture Module. This module provides a simulated telephone line that will accept "calls" from the dialer which are then transmitted by the SPT via IP, RADIO or PSTN.
