Abstract
The methods, systems, and apparatuses described in this disclosure enable the identification of an alarm condition and the termination of a connection between an MTA and one or more telephony devices. An alarm condition can be identified at an MTA through the monitoring of feedback received from an alarm interface, and the MTA can respond to the identification of the alarm condition by terminating a connection to a telephony device for which communications are not routed through a corresponding alarm interface. An interface between the MTA and alarm interface may route communications to and from a telephony network through a first pair of wires and may receive feedback from the alarm interface through a second pair of wires.
