INTRODUCTION
This manual describes the ADC DSX-3 Interbay Patch panel and its use in multiple bay single
lineups, and in multiple bay multiple lineups DSX-3 Systems. The panel is described both
physically and functionally, and simplified schematic diagrams are included to show
interconnecting cabling and circuit patching operations. Installation instructions are also provided
showing cabling interconnections on each panel. Signals are patched from one bay to another
through the interbay panel instead of stretching patch cords from one bay to another.

INTERBAY PATCH PANELS
Each patch circuit on the Interbay Patch Module consists of four jacks and a busy indicator with
toggle switch as shown in Figure 1. The jacks are designated; LEFT OUT, LEFT IN and RIGHT
IN, RIGHT OUT. The LEFT jacks are used to patch to the bays to the left of the Interbay Patch
Module (standing in front of the module), and the RIGHT jacks are used to patch to the bays to
the right of the Interbay Patch Panel. A manually activated LED or lamp provides a circuit busy
or in use indicator. The Interbay Patch Modules have BNC on the back of the Module for
interconnect cabling between Modules.
Interbay Patch Panels in DSX-3 Bay Systems provide the capability to patch between two DSX3 circuit locations that are several bays or lineups apart without using long patch cords. A
circuit patch is set up in two steps; 1) from the originating DSX-3 termination and to a patch
jack circuit on the nearest Interbay Patch Panel; 2) from the terminating DSX-3 termination to
the corresponding patch jack circuit on a nearby Interbay Patch Panel.
The patch circuit busy indicator is normally dark. When Toggle switch is placed in the IN USE
position, the LED’s at each multiple point flash for approximately 30 seconds and then remain
lighted indicating circuit is in use. The patch jack circuit multiple wiring is such that the circuit
is open in the opposite direction of the patch setup. That is, if the setup is to the left, the left jack
is used and opens the jack multiple to the right.
19482-A
Figure 1. Interbay Patch Panel with LED Indicators
Interbay patching panels are normally located in every fourth maintenance bay within DSX-3
lineups. Interbay patch panels are used for patching between bays when patch cord lengths
become excessive. These panels are placed in each maintenance bay allowing the use of a series
of short patch cords to connect any two DSX positions in the same or adjacent bay lineups. The
originating DSX position is patched to the closest interbay panel and from there the signal is
transmitted via tie cables to the other interbay panels in the bay lineup(s). The signal is then
patched from an associated interbay panel to the terminating DSX position to complete the
circuit. Interbay patch panels are available with either standard or midsize jacks.

ADCP-80-374 • Issue 1 • May 2004
Toggle switches are used to isolate the Interbay Patch LED circuit from the remaining Interbay
Patch panels in the series. The toggle switch also activates the busy LED. The patch circuit busy
indicator is normally dark. After inserting a patch cord and the toggle switch is moved to the “In
Use” position, the busy indicator lights at each multiple point of the patch circuit. When the In
Use switch is moved from the Idle position, the patch jack circuit multiple wiring is such that
the circuit is open in the opposite direction of the patch setup. That is, if the setup is to the left,
the left jack is used and opens the jack multiple to the right.
A typical interbay patch panel application is shown in Figure 2. Cable and cross-connect
distance requirements vary depending upon the application and cable type. Refer to ADC
Application Note 1228 for additional information.

INSTALLATION
Installation of Interbay Patch Panels in various DSX-3 bays involves installation of the panel,
interconnection of the LED circuits on the terminal blocks at the back of the modules,
terminating of BNC connectors from panel to panel, and connection of battery and battery
return leads to power the LED indicators.
Warning: Never install telephone equipment in a wet location or during a lightning storm.
When installing or modifying telephone lines, disconnect lines at the network interface before
working with uninsulated lines or terminals to prevent electrical shock.
4.1
Chassis, Module and Panel Positioning and Mounting
The package of loose parts contains mounting screws and installation drawing. Panels have
optional mounting positions. The panel can be mounted flush, or with a two, or four inch recess.
Place mounting brackets on the panel and install in the assigned bay position using 12–24 × 0.5
inch mounting screws. See Figure 3. Choose the best mounting option for the environment and
type of equipment rack used.

SYSTEM WIRING AND CABLING
Wiring and cabling of the DSX interbay patch panel into the office requires connection of office
power and ground and cabling of interbay panels to each other (right jacks of one panel to left
jacks of next panel). The following paragraphs give procedures for installing wiring and cabling.
Caution: All DSX interbay panel wiring and cabling should be connected with the system office
battery input off or with the fuses removed at the fuse panel.
5.1
Power Wiring
The DSX interbay patch panel operates on –48 Vdc filtered office battery, fused or breakered at
the rack fuse panel. Current requirements can be calculated based on 0.008 Amps maximum per
flashing LED. Equipment racks are normally equipped with a fuse panel located at the top.
The number of LEDs or lamps lit at any one time will depend on local patching and testing
procedures. It is recommended that each interbay patch panel be fused at the fuse panel with a
0.5 amp fuse and connected to the fuse panel using 22 AWG solid tinned copper wire. Spade
terminals should be used for connection to the screw terminals. A typical interbay patch panel
power terminal strip is shown in Figure 4.
19483-A

Connect each panel to the fuse panel as follows:
1. Connect –48V terminal on the chassis to a NEG (–) distribution terminal on the fuse panel.
2. Connect B GND terminal on the chassis to the corresponding POS (+) distribution
terminal on the fuse panel.
3. Connect chassis ground to the office grounding system. The chassis ground is often
grounded to the equipment rack which in turn is connected to the office grounding system.
5.2
Busy LED Cabling
Interbay LED circuits are connected together using the two wire wrap blocks located at the back
of each panel. The left wire wrap block is connected to the previous (right) interbay jack circuits
and the right wire wrap block is connected to the next (left) interbay circuits. Each Interbay
Patch Panel is daisy-chained to the previous or next Interbay Patch Panel in a similar fashion.
LED circuit wire wrap terminations are shown in Figure 5.

Interbay Patch Panel Cabling
Interconnect all interbay patching panels using coaxial cables with BNC connectors at the back
of each panel. Interpanel cabling is shown in Figure 6. Daisy-chain cabling is used with circuits
dedicated to other DSX-3 bays as shown in Figure 7. Interbay patch circuits between lineups
may require I/O repeaters if the total patch length between DSX positions exceeds their limit.
Refer to ADC Application Note 1228 for additional information. The tie cables between
interbay patch panels are wired so that outputs on one panel are wired to the inputs of the other
panel as shown in Figure 6.

INTERBAY PATCHING BY MEANS OF SHORT PATCH CORDS
This procedure is used to patch between bay lineups or between distant bays in the same lineup,
without the use of long patch cords. Patching is accomplished with several short patch cords,
using the interbay patch panels. A typical example is when a DSX circuit is patched from lineup 1
to lineup 2 via interbay patch panels in maintenance bays.

Troubleshooting
Troubleshooting of the Interbay Patch Panel consists of visual inspection and continuity testing.
Cross-connections can be quickly checked by bypassing them with patch cords to the
corresponding IN and OUT jacks.
8.2
Tracer Lamp Replacement
Burned out tracer lamps are replaced at the front of the Interbay panel. Lamps are removed by
pulling them from the panel sockets. No special tools are required. Replacement lamps must be
inserted with the negative (–) terminal up.
8.3
Fuse Replacement
Burned out fuses are replaced at the front of the fuse panel. Fuses are removed by pulling them
from the panel sockets and installed by pressing them into the panel sockets. No special tools
are required.
Caution: A replacement fuse must have exactly the same current rating as the fuse being
replaced.
