Voice Testing with the FrameScope Pro 3
How the FrameScope Pro Tests Voice Quality
Agilent FrameScope Pro User’s Manual 87
How the FrameScope Pro Tests Voice Quality
To test voice quality and measure audio circuit characteristics,
the FrameScope Pro VoIP does two things:
It places and/or answers one telephone call at a time to
establish voice connections. This voice connection (and the
transmission media and equipment of which it is comprised)
becomes the network under test. Think of the FrameScope Pro
VoIP as a telephone or other telephony device positioned at the
ends of voice circuits.
Once the FrameScope Pro VoIP has established at least one
telephone call, it transmits audio test packets onto that
circuit and measures how those packets are affected by
traveling through the network under test. The FrameScope
Pro VoIP can send test packets in one direction at a time
depending on how that circuit was established.
