VFRADVoice Over Frame Relay Access Device
References in periodicals archive ?
Call processing -- If a VFRAD cannot route into and out of the same frame relay port, it limits the call routing paths you can create, which could result in tandem compressed calls.
The need for reasonable end-to-end delay and moderate jitter requires that VFRADs segment much of the data traffic passing through.
Common VFRADs have compression delays that range from 15 to 20 milliseconds.
Jitter buffers -- Mandatory in VFRADs, these allow the voice to sound smooth and coherent.
