Copper :: Part Number 117389-4
1.1 Overview
Figure 1 - 23-inch, 32-circuit BCSII With 6-Port DSX Card Modules
The Telect Broadband Connectivity System II (BCSII) is a family of related products providing a high-density
environment for cross-connecting and interconnecting DS3, STS-1, E-3, STM-1, and STS-3 signals from
broadband equipment such as digital radio, multiplexers and 3:3 or 3:1 DCS. Available components include
several 19-in and 23-in chassis with integrated backplanes.
The chassis accommodate three, four, or six-port DSX and six-port DNI card modules with frontpanel patching.
Other Telect card modules (simplex and duplex repeaters and optical/electrical

Copper :: Part Number 117389-4
1.1.1 Capabilities
The Telect DSX-3 system enables patching, cross-connecting, interconnecting, test and monitor
functions for digital signals in 75 ohm systems for the following bit rates:
E3 34.368 Mbps
DS3 44.736 Mbps
STS-1 51.84 Mbps
STS-3 155.52 Mbps
STM-1 155.52 Mbps
The maximum number of cross-connect cards in a 7 ft x 23 in. x 12 in. equipment bay with 14
chassis is 448 cards.
1.1.2 Features
The BCS II has the following features:
• There are 32-active or mixed circuits per chassis; 48 per passive 8 x 23 in. chassis.
• Customers can pre-terminate network elements and pre-wire cross-connect assignments on-site.
• Front and rear tracer lamps display circuit cross-connects.
• Bidirectional monitoring is available.
• Card modules use Mini-WECO jacks and BNC or 1.6/5.6 connectors.
• The BCS II provides exible cable management options.
• DNI cards and DNI-only chassis are available. (Note that the DNI card modules do not require power.)
• DNI cards t DSX chassis.
• The BCS II provides 19 in. or 23 in. chassis.
• The BCS II is available for WECO, EIA, ETSI racks.
• Modules can be mixed in the same chassis.
• Alarm outputs are available on the DSX chassis for those active card modules capable of generating critical,
major, and/or minor alarms

1.2 DSX Chassis & Passive Card Modules
1.2.1 DSX-3 Rear Cross-Connect Chassis
Typical DSX-3 rear cross-connect chassis are shown in the illustrations on the following pages:
• 23-in., 32-Circuit DSX Chassis, page 5
• 19-in., 24 -Circuit DSX Chassis, page 6
• 23-in., 24-Circuit DSX Chassis, page 7
• 23- & 19-in. Horizontal Chassis (10 & 8 Circuits, respectively), page 8 & 9
All DSX chassis have integrated backplanes with tracer lamps. Vertical DSX chassis can accommodate any active
or passive BCSII card module.
Rear plates with BNC connections are alternately nished black, white, black, white, etc.
The following table lists all empty 19-in. and 23-in DSX-3 chassis models. Fully pre-loaded
chassis containing DSX modules are listed in the following subsection.
