PVIT stands for Packet-Voice-Impairments-Test or Packet-Voice-Integrity-Test. It is one of a series of VQT (Voice-Quality-Test)tests designed by Sage to speci?cally address the next generation VoP (Voice-over-Packet)applications. Other related VQT tests available from Sage are PSQM and Echo Sounder. By VoP we include all the three dominant technologies: Voice over Frame Relay (VoFR), Voice over IP (VoIP)and Voice over ATM (VoATM). One may hear other “buzz ”words such as voice over DSL, voice over Cable, and voice over LAN Ethernet etc. But DSL, Cable and Ethernet are simply different physical access or transmission media. The underlying technologies remain to be Frame Relay, IP or ATM.
