SCC1 Media Gateway
Slot 2 contains an EI or, for S8700-series Media Server only, an ATM Interface circuit pack
for a critical-reliability system. Slot 3 would also contain an EI circuit pack for direct-connect
critical-reliability system. Otherwise, all slots are available for optional circuit packs.
For an IP-PNC PN, slot 1 contains an IPSI circuit pack when the cabinet is in the B position
and the PN is connected to a duplicated control (high reliability) network. The other slots in
a port carrier can contain optional port circuit packs.
The following figure shows an example of a port cabinet.

An Expansion Interface port that provides an interface for a fiber-optic
cable. This cable runs either to an Expansion Interface circuit pack in
another PN or a Switch Node Interface circuit pack in a center-stage
switch. For an ATM configuration, these slots contain an ATM interface
circuit pack, and a fiber-optic cable connects out of the front of the circuit
pack to an ATM data switch.
25-pair connectors that provide interfaces between the port circuit packs
and the cross-connect field or a fiber optic transceiver.
