Port network cabinet for Avaya S8500 Media Server
MCC1 Media Gateway
The Avaya S8500 Media Server supports the MCC1 Media Gateway in migrations from a
DEFINITY R or DEFINITY SI simplex configuration. A maximum of three PNs are supported in a
direct connect configuration only. However, up to 64 PNs are supported when IP-PNC PNs are
combined with fiber-PNC PNs in the configuration.
Expansion port network cabinet for DEFINITY Server SI
An expansion port network (EPN) cabinet contains the following carriers:
● One to four port carriers (J58890BB), one of which may serve as a duplicated expansion
control carrier in a critical reliability configuration in position B
● One expansion control carrier (J58890AF) in position A
An EPN cabinet is the same as the PPN cabinet, except the carrier in the A position and,
sometimes, the carrier in the B position differ from those in a PPN cabinet. See MCC1 EPN or
PN cabinet on page 202 for an example of an MCC1 EPN cabinet.
