GENERAL
1.1
Document Purpose
This document describes how to install the 3192–9B Bridging Office Repeater, shown in Figure 1
1.2
Document Status
This document is reprinted to provide a general editorial update.
1.3
Equipment Function
The 3192–9B Bridging Office Repeater is designed for use in any of the 28 transmission module slots in the
3192–11 Span Termination System (STS) Mounting Shelf. See the following documents for addition information:
1.4
Section 319–211–100 (Wescom Span Termination System General Description)
Section 319–211–200 (Wescom Span Termination System Installation)
Equipment Features
The 3192–9B Bridging Office Repeater (BOR) has the following features:
2.
Selectable secondary T1 or Quasi-Random Signal Source (QRSS) output.
Pre-equalization for up to 655 feet of cable at the primary and secondary outputs.
Front-panel jacks for Monitor T1 Input, Primary T1 Output, and Secondary Tl/QRSS output.
APPLICATION GUIDELINES
The 3192–9B Bridging Office Repeater has two different applications. It can be used as a maintenance aid for
span patching, rerouting service onto a Maintenance Span Line. It can also be used as a source of timing by providing a tap for bridged access to primary T1 lines.
3.
INSPECTION
Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately report the extent of damage to the transportation company.
Charles Industries equipment is identified by a model and issue number imprinted on the front panel or located
elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue
number is advanced by one number on any following models that are manufactured. Therefore, be sure to include
both the model number and its issue number when making inquiries about the equipment, 3192–9B Maintenance
Application; Transferring to an Idle Line Without Interruption
Modules are shipped in static-protective material to prevent electrostatic charges from damaging CMOS devices.
Use approved static-preventative measures when handling modules outside of this protective material. A module
intended for future use should be tested as soon as possible and returned to its protective shipping material for
storage.
STATICSENSITIVE
Units are shipped in staticprotective material to protect staticsensitive devices. Use staticpreventive
measures for storage and handling.

MOUNTING
The 3192–9B BOR mounts in any one of the first 28 positions of the 3192–11 Mounting Shelf, or any of the first
21 positions of a 19-inch mounting shelf. The remaining rightmost position of the mounting shelf is used to mount
a 3192–9F Alarm Module, which is 2 mounting positions wide.
CAUTION
Installation and removal of modules should be done with care. Do not force a module into place. If
excessive resistance is encountered while installing a module, remove the module and check the card
guides and connector to verify proper alignment and the absence of foreign material.
Use the following steps to mount the office repeater:
Step
Action
1.
Rotate the securing bar by pushing the spring clip tab on the left pivot point away from the shelf, while
rotating the bar up and out of the way. The spring clip will hold the bar up and in place so that the module can be removed or inserted.
2.
Insert the module.
3.
Push back the spring clip tab and rotate the bar back into place.

Section 319–29B–302
5.
INSTALLER CONNECTIONS
All connections to the 3192–9B are made through the shelf. See the shelf documents for connector and cable
information.
6.
OPTIONS
The 3192–9B is equipped with slide switches that are used to condition the module for proper application and operation. Refer to Figure 3 for option locations and option summary.
6.1
Slide Switch S1 (Secondary Output)
Slide switch S1 is used to control the secondary output of the 3192–9B. When S1 is in the QRSS position, a standard quasi-random signal source will appear at pins A and 1 of the module’s edge connector and at the front-panel jack, labeled SEC OUT/ QRS. This signal can be used for testing or as a keep-alive signal on the maintenance
spare T1 line, Placing S1 in the DAC/SEC position will allow the 3192–9B to produce two identical T1 outputs
from a single input. The primary output will appear on pins B and 2, while the secondary output will appear on
pins A and 1. This feature can be used to provide two timing sources from one T1 line.
OPTION
FUNCTION
S1
Placing switch S1 to the DAC/SEC position causes the secondary output to repeat the repeater input signal. Placing switch S1 to the QRSS position causes the secondary output
to repeat the internal quasi-random signal source.
S2
Slide switch S2 optimizes the primary output signal (PRI OUT) from the repeater to the
DSX for 0–220, 221–440, or 441–655 feet of ABAM cable.
S3
Slide switch S3 optimizes the secondary output signal (SEC OUT) or the QRSS output
from the repeater to the DSX for 0–220, 221–440, or 441–655 feet of ABAM cable.

Section 319-29B-302
6.2
Slide Switch S2 and S3 (Pre-equalization)
Slide switches S2 and S3 control the amount of pre-equalization applied to the primary and secondary outputs,
respectively. Placing the switches in the 220 position optimizes the T1 output going toward the DSX for up to 220
feet of ABAM cable. The 440 position is used for cable lengths between 221 and 440 feet, and the 655 position is
used for lengths between 441 and 655 feet. Refer to Table 1.

TESTING
Proper operation of a 3192–9B BOR module can be determined by patching a monitor-level signal into the BOR
IN jack on the front panel, and then connecting a signal monitor device to the PRI OUT jack to verify signal passage through the BOR. If the BOR is optioned for providing a secondary output signal, a signal monitor device
can be connected to the SEC OUT jack as well. Alternatively, patching the PRI OUT signal (or SEC OUT signal)
to any inactive repeater receive side RPT jack while viewing its LOS indicator can also verify that the 3192–9B
BOR is passing a DS1 signal.
