Inter-circuit line fault location in telecommunication networks |
摘要 |
Circuit faults between different circuits in a telecommunications network are located. In this invention a test signal is generated on a particular circuit and all adjacent circuits are tested for the presence of the test signal. Using information from a routing database the likely location of a circuit-to-circuit fault may be determined.
