• The pp VBRnrt (Variable Bit Rate) virtual circuits between A500 ports A1.1 (PPN) and A1.2
(PN) are used for signaling between the PPN and each PN.
• These are established once upon initialization under control of S8700 Multi-Connect call
processing. They represent the ATM Control Link (ACL) and Expansion Archangel Link (EAL).
• VBRnrt virtual circuits are also be used for ISDN channels between S8700 Multi-Connect PNs.
• Other VBRnrt virtual circuits may exist between A500 ports that are not associated with S8700
Multi-Connect PNs. A common use of VBRnrt circuits is multimedia and video-conferencing
systems.
