■
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.
■
These are established once upon initialization under control of Avaya
MultiVantage Software running on the Definity Server CSI. They represent
the ATM Control Link (ACL) and Expansion Archangel Link (EAL).
■
VBRnrt virtual circuits are also be used for ISDN channels between Avaya
Definity Server CSI port networks.
■
Other VBRnrt virtual circuits may exist between A500 ports that are not
associated with Avaya Definity Server CSI port networks. A common use of
VBRnrt circuits is multimedia and video-conferencing systems.
