1. A system for determining the status of a telecommunications circuit, including:

  • (a) a monitoring device located at a network interface between the telecommunications circuit and a customer installation, generating data derived from the content of signals received by the monitoring device from the circuit and transmitting the generated data; and

    (b) a sectionalizer device, coupled by the circuit to the monitoring device, receiving said generated data from the monitoring device, detecting when an Event has occurred, and determining, based upon the generated data, in which portion of the circuit from among multiple circuit portions the Event originated;

    wherein signals transmitted over the circuit include both a payload and overhead, and the signals received by the sectionalizer device from the monitoring device indicate both inability to detect a payload and degradation of the signal due to errors in either the payload or the overhead.
