Abstract
A system and method of troubleshooting a communication connection for a remotely located security system is disclosed. A communication line test unit is incorporated into the remote security system and its communication unit. A central control unit can then contact the remote security system communication unit, enable the communication line test unit and perform tests on various operational parameters of the communication unit located in the remote unit and the communication connection of the local unit. The tests conducted can include loop current, tip to ring voltage, ring to ground current, circuit loss, circuit noise, power influence as well as other tests. Based on the results of these tests a determination can be made if the problem is an extraneous influence, such as a poor local telephone line connection, or some problem with the security system communication unit itself.
