Virtual Call ID - Device ID used to query interdomain calls after they
leave the origination domain and enter a transit domain or the
destination domain. The virtual call ID consists of the node ID and
a random card and port ID The virtual call ID is assigned by the
inbound gateway node in the domain. The call is assigned a
virtual call ID for each domain it goes through.
Virtual Circuit - A virtual circuit is a communications link that
appears to be a dedicated point-to-point link but is not. It delivers
data packets in guaranteed sequential order just as they would be
received over a point-to-point circuit. The applications for virtual
circuit packets include DS1 dialed digit packets and EIA signal
information packets for synchronous data ports.
Virtual ISDN - An alternative to repeaters which uses a local Telco
Switch to act as a repeater and which then sends the signal onto
another switch which supports ISDN. See also Repeater.

VOX - (Voice Operated Relay Circuit) Module - This module
performs voice activity detection on 24 voice channels input
through a DSP module when DSI compression is used. This
module, along with the N.E.T. ADPCM and DSI modules,
provides a speech compression method to increase the capacity
of a multichannel trunk to transmit voice.

VP - virtual path
VPF - vector product format
VPI - virtual path identifier
VPN - Virtual Private Network
VPRN - Virtual Private Remote Networking
VPT - Virtual Private Trunking
VQ - (Vector Quantization) - This is the voice compression algorithm
for the VCFAX module.
