A500 port A1.1 (PPN) and A500 port A1.2 (EPN) are used for talk
paths between EPNs (PPN to EPN, EPN to PPN, or EPN to EPN).
Each virtual circuit represents one party of a complete multiparty talk
path.
point-to-multipoint virtual circuit from A1.1 to A1.2, and another from
A1.2 to A1.1.
call. The S8700 Multi-Connect call-processing software saves
virtual circuits for a few seconds after the end stations have hung
up, in case the VC can be reused for another call between the same
two EPNs.

application is circuit emulation, where T1, T3, etc. circuits are
carried over ATM.
