Any error will force the C900TTL-X to switch the Alarm Paneldialer to the Fallback (phone line backup) position for 2 minutes when the Alarm Panel next seizes the line (ifenabled, and if the seize occurs within 2 minutes). Intercept errors are always reported to the D6600 Receiver. Ifthe D6600 Receiver does not acknowledge a signal sent that was intercepted by the C900TTL-X in the properamount of time, the Alarm Panel digital dialer will hang up and retry the message transmission.
