Abstract
Esta invención trata de sistemas de telecomunicación y, más específicamente, un dispositivo de monitoreo e informe del estado de las líneas telefónicas para usarse entre el bucle en el predio del abonado y una red telefónica local. El dispositivo funciona en corriente de bucle, alimentación externa de CA o CC del predio del abonado o una pila interna. El dispositivo monitorea pasivamente el estado del bucle del predio hasta que se detecte una condición de alarma. Cuando el equipo de comunicación del predio está colgado o descolgado, el dispositivo detecta las condiciones normales del voltaje y la corriente de punta a nuca. Si se detecta una condición de circuito abierto, cortocircuito o impedancia del bucle inválida, el dispositivo indica una posible falla en el cableado del predio. El dispositivo entonces informa de la alarma ya sea por indicaciones visuales o audibles electrónicamente a un dispositivo de monitores externo o por el autodiscado de uno de dos números telefónicos preprogramados. Se puede informar acerca de la falla por la línea telefónica alámbrica o radioenlace a la oficina central u otro lugar. Además, cuando está configurado para la comunicación con la oficina central por radioenlace, el dispositivo puede ser reajustado en forma remota.This invention deals with telecommunication systems and, more specifically, a device for monitoring and reporting the status of telephone lines for use between the loop at the subscriber's premises and a local telephone network. The device operates on loop current, external AC or DC power from the subscriber's premises, or an internal battery. The device passively monitors the state of the property loop until an alarm condition is detected. When the communication equipment on the premises is on or off the hook, the device detects normal voltage and current conditions from head to toe. If an open, short, or invalid loop impedance condition is detected, the device indicates a possible field wiring fault. The device then reports the alarm either by visual or audible cues electronically to an external monitoring device or by autodialing one of two preprogrammed phone numbers. The failure can be reported over the landline or radio link to the central office or other location. Additionally, when configured for communication with the central office via radio link, the device can be remotely reset.
