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

1.4.1 Repeater Card Modules
The repeater cards enable increased separation up to 900 feet (274 m) between crossconnected network elements,
using ATT 734A cable. Repeater cards can be stationed at 900 feet intervals to allow unlimited signal repetitions.
The simplex repeater card (710-3201-0002) is always used in pairs. The duplex repeater card (710-3201-0005)
contains two simplex repeaters with a common power supply Consult the Simplex Repeater User Manual and the
Duplex Repeater User Manual for operational details.

1.4.2 Vector Optical Transport Module (OTM) Card Modules
The Vector OTM (or optical/electrical converter) card modules convert single-mode or multimode ber optic
signals to electrical signals and vice versa. All ber optic connectors are located at the front of the modules.
Telect manufactures both single-mode and multimode converters with either ST or SC connectors. A
hardened version of the single mode optical/electrical converter with SC connectors is suitable for extended
temperature operation.
Consult the Vector Optical Transport Module (OTM) User Manual for operational details.

1.5 Power Distribution
You can use a wide variety of -48Vdc power distribution panels to provide power to a DSX chassis. If your installation
includes repeaters or other active products, use a dual-feed power distribution panel (PDP) to ensure power
availability in case one power feed fails. One appropriate PDP for this application is Telect Model 06004-11, shown
in the following illustration. Model 06004-11 is a dual-feed GMT PDP with 20 fuse positions per side and a total
output load capability of 20A.
Use the following power specications to select the proper PDP for your application:
• DSX cards draw 18 mA total, 9 mA for each tracer lamp.
• Repeater cards draw up to 60 mA each.
• Optical/electrical converter cards draw up to 180 mA.each.
Fuses for each chassis must be 1-1/3 amp. Use 22 AWG wire (minimum) for power distribution to each chassis.
Use red wire to connect to RTN and black for BATT. Remember that all PDPs and BCSII chassis require grounding,
including DNI chassis.
