Abstract:
A communications network comprising:a modem termination system (MTS); a voice band tester (VBT) coupled to the MTS, the VBT being located at a first location; a modem tester coupled to the MTS, the modem tester being located at a second location remote from the first location, the modem tester adapted to provide a first communication signal to the VBT via the MTS; and a Voice over Internet Packet (VoIP) monitoring device coupled to the MTS and the VBT, the VoIP monitoring device adapted to monitor the first communication signal, and calculate a first Quality of Services (QoS) score based on traffic density between the MTS and the VBT: wherein the VBT is adapted to: calculate a first Transmission Impairment Test (TIT) score based on the first communication signal and a first received communication signal received by the VBT from the modem tester, and provide the first TIT score to the VoIP monitoring device; the VBT is further adapted to provide a second communication signal to the modem tester via the MTS; the modem tester is further adapted to calculate a second TIT score based on the second communication signal and a second received communication signal received by the modem tester from the VBT, and provide the second TIT score to the VoIP monitoring device; and the VoIP monitoring device is further adapted to monitor the second communication signal, and calculate a second Qos score based on a transmission of the second communication signal from the VBT to the modem tester.
