Connector Panel Interfaces
2-6 July 2004 Wide Bank 28 DS3 - Release 2.4
Connector Panel Interfaces
The connector panel on the rear of the chassis housing contains the following connectors and power
connection terminals.
 Low-Speed Connectors. Together these two 64-pin Champ type connectors support 28 DS3 or
21 E1 ports. One is designated as LOW SPEED IN, and the other is designated as LOW SPEED
OUT. The cable connecting to these ports (the same cable is used on both ports) has a male 64-
pin Amphenol
®
connector on both ends for connections between the patch panel or other
equipment, and the Wide Bank 28 DS3. (Cables are available in 10-foot and 25-foot lengths.)
 DS3 Connectors. There are four DS3 connections: Primary (Active) in and out, and Secondary
(Protection) in and out, which make up two DS3 ports. Each Controller card has a single DS3
interface, so the Wide Bank 28 DS3 must have two Controller cards installed to have two DS3
ports available.
 Ethernet Connector. The Ethernet interface (RJ-45) provides management access to the Wide
Bank 28 DS3. The LED associated with the Ethernet port provides a carrier-detect indicator for
the 10Base-T connection when green.
 RS-232 Monitor Connector. This is an RS-232 port (DB-9 female) that can connect to a VT-100
terminal or a PC with terminal emulation software to manage the active Controller card via the
Command Line Interface (CLI).
 RS-232 TL1 Connector. This is an RS-232 port (DB-25 female) for Automated Outbound
Alarming and Wide Bank management from a remote operating system.
