Abstract:
1. A system comprising: an optical line terminal, at a central office, to serve as a point of origination for a signal associated with a target, the signal coming into or going out of a fiber optic network; a phone switch, at the central office, to communicate with the fiber optic network via the optical line terminal; an analog circuit disposed at a location between the phone switch and the optical line terminal such that the signal, transmitted between the target served by the fiber optic network and a subscriber, is propagated along the analog circuit; and a monitoring device to monitor the signal while the signal is propagating along the analog circuit, where the optical line terminal comprises first and second terminal interface cards, where the analog circuit is routed, from the first terminal interface card, to the monitoring device, and to the second terminal interface card, where the first terminal interface card comprises one of a Remote Universal Voice Grade card or a Remote Plain Old Telephone Service card and is to convert the signal for transmission on the analog circuit, and where the second terminal interface card is to convert the signal for transmission from the analog circuit to the phone switch.
