Figure 51: Expansion control cabinet (J58890N)
The following table describes the connectors in the expansion control cabinet.
Port cabinet for a DEFINITY Server SI,
S8700-series Media Server, or S8500 Media Server
Port cabinets reside in the DEFINITY Server SI PPN and in expansion PNs. An AC or a DC
power supply resides in the right side of each cabinet. A TN755 neon power unit can be
installed in slot 18, which uses some of the space of slot 17 and prevents the use of slot 17.
For a DEFINITY Server SI PPN, all slots are available for optional circuit packs.
For a fiber-PNC PN, slot 1 contains a Tone-Clock circuit pack when the port cabinet is in
the B position of a PN in a duplicated control/duplicated bearer (critical-reliability) system.
Connector Function
1 (A1) Provides a fiber-optic cable interface to an expansion interface (EI)
circuit pack in slot 1
1
or a copper cable interface for a DS1 Converter.
1. In systems that use ATM-PNC, the fiber connectors for the OC-3/STM-1 interfaces to the ATM switches
reside on the faceplates of the TN2305 or TN2306 circuit packs.
2 to 17 (A2 to A17) 25-pair connectors that provide interfaces between the port circuit
packs and the cross-connect field or a fiber optic-transceiver.
AUX (auxiliary) Provides interfaces for customer alarms, attendant console power,
and emergency transfer panels.
TERM (terminal) Connects an administration terminal to the maintenance circuit pack
and is used only for the DEFINITY Server SI. This connector is not
used for the S8700-series Media Server or the S8500 Media Server.
