The pp VBRnrt (Variable Bit Rate) virtual circuits between A500 ports A1.1
(PPN) and A1.2 (EPN) are used for signaling between the PPN and each
EPN.

VBRnrt virtual circuits are also be used for ISDN channels between
Definity port networks.

Other VBRnrt virtual circuits may exist between A500 ports that are not
associated with DEFINITY port networks. A common use of VBRnrt circuits
is multimedia and video-conferencing systems.
