Admonishments
Important safety admonishments are used throughout this manual to warn of possible hazards to
persons or equipment. An admonishment identifies a possible hazard and then explains what may
happen if the hazard is not avoided. The admonishments — in the form of Dangers, Warnings,
and Cautions — must be followed at all times. These warnings are flagged by use of the
triangular alert icon (seen below), and are listed in descending order of severity of injury or
damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe
personal injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause
minor personal injury or property damage if the hazard is not avoided.
1. GENERAL
1.01 This manual describes the ADC DSX-1 and DSX-1C Interbay Patch Module and its use
in multiple bay single lineups, and in multiple bay multiple lineups DSX Systems. The Module 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 to termination blocks on each Module.
2. DESCRIPTION
2.01 Interbay Patch Modules in DSX-1 Bay Systems provide the capability to patch between
two DSX circuit locations that are several bays or lineups apart without using long patch cords.
Acircuit patch is set up in two steps; 1) from the originating DSX termination and to a patch
jack circuit on the nearest Interbay Patch Module; 2) from the terminating DSX termination to
the corresponding patch jack circuit on a nearby Interbay Patch module.
2.02A typical 28 circuit Bantam Jack Interbay Patch Module (rear view) is shown in Figure 1.
The Interbay Patch Module is available in various dimensions with either 25 or 28 circuits using
Bantam jacks. A LED or lamp provides a circuit busy or in use indicator. The Interbay Patch
Modules have terminal blocks on the back of the Module for interconnect cabling between
Modules.

2.03 Each patch circuit on the Interbay Patch Module consists of four jacks and a busy
indicator as shown in Figure 2. The jacks are designated; OUT L, IN L and OUT R, IN R. The L
(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 R (right) jacks are used to patch to the bays to the right of the
Interbay Patch Module.
2.04 The patch circuit busy indicator is normally dark and when a patch cord or plug is
inserted in a jack the light flashes for about 30 seconds then remains lit. The busy indicator lights
at each multiple point of the patch circuit. 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. See Figure 3, 4, 5 and 6.

3. APPLICATION AND OPERATION
3.01 It is recommended that Interbay Patch Modules are installed and wired as shown in
Figure 7. As shown, typically the modules are installed in maintenance bays in each DSX-1
system lineup. For simplicity only two circuits on each module are shown in multiples between
modules within the lineup and two circuit multiples between modules in other lineups. In reality
the circuits should be split; half multiples within the lineup and half multiples to other lineups.
3.02 Circuit patching can be accomplished with two or three sets of short patch cords when
wired as recommended. The following examples describe patch procedures in a single lineup and
in a multiple lineup. See Figure 7.
Caution: A patch cord or plug inserted into any jacks of an established patch set up will
interrupt the circuit.

Example 1: Single Lineup Patch
1. Patch a DSX circuit on bay 6 of lineup 1 to a DSX circuit on bay 18 of lineup 1.
a) Install patch cords from the desired DSX circuit on bay 18 to an upper left set of
IN/OUT jacks on the bay 19 Interbay Patch Module. The busy indicator on all jacks
multipled to the selected jack circuit will flash for about 30 seconds and then remain
lit to indicate all patching jacks that may be used for the patch setup.
b) Install patch cords from the desired DSX circuit on bay 6 to the upper right set of
IN/OUT jacks on bay 7 corresponding to the flashing busy indicator. This will
extinguish busy indicators in bays 3 and 7. The busy indicators for jacks in the
circuit on bay 11 and 15 will remain lit to show this interbay circuit is in use. A plug
inserted into the jacks of this circuit on bays 11 or 15 will interrupt the patched
circuit.
Example 2: Multiple Lineup Patch
1. Patch a DSX circuit on bay 1 of lineup 1 to a DSX circuit on bay 17 of lineup 3.
a) Install patch cords from the desired DSX circuit on bay 1 of lineup 1 to a lower right
set of IN/OUT jacks on lineup 1 bay 3 Interbay Patch Module. The busy indicator on
all jacks multipled to the selected jack circuit will flash for about 30 seconds and
then remain lit to indicate all patching jacks that may be used for the patch setup.
b) At bay 3 in lineup 3, install patch cords from the lower left set of IN/OUT jacks
corresponding to the flashing busy indicator, to an upper right set of IN/OUT jacks.
The busy indicator that was flashing for this patch circuit on bay 3 of lineup 3 will
be extinguished, and the busy indicator for the jacks multipled to the right set of
jacks will start flashing.
c) Install patch cords from the desired DSX circuit on bay 17 of lineup 3 to the upper
left set of IN/OUT jacks on bay 15 corresponding to flashing busy indicator. The
busy indicators for this patch circuit on bays 15 and 19 of lineup 3 will be
extinguished. The busy indicator for this patch circuit on bays 7 and 11 in lineup 3
and bay 3 in lineup 2 will remain lit to show that this patch circuit is in use.
4. INSTALLATION
Warning: To prevent electrical shock, 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.
4.01 Installation of Interbay Patch Modules in various DSX-1 bays involves the
interconnection of the circuits on the terminal blocks at the back of the modules and connection
of battery and battery return leads for the LED indicators. Office power to the Interbay Patch
Module should be fused at 0.5 Amp. Use a minimum of 22 AWG wire when making power
connections.

Figure 8. Typical Bantam Interbay Module Power Terminal Strip
A. Power and Ground Connections
4.02 A typical DSX-1/1C Interbay Patch Module power terminal strip is shown in Figure 8.
Connect each module to the fuse module as follows:
1. Connect the –48V terminal on the module to a NEG (–) terminal on the fuse module
(white wire).
2. Connect the GND terminal on the module to the corresponding POS (+) terminal on the
fuse module (black wire).
3. Connect the CG terminal on the module to the office frame ground (green wire). This the
recommended chassis grounding procedure.
Note: The metal strap between the CG (Chassis Ground) and SG (Shield Ground)
terminals on the module may be removed to isolate the shield ground from the chassis
ground.
B. Interbay Interconnection Wiring
4.03 Interbay circuits are connected together using the 12 terminal blocks located at the back
of each module. Terminal block pins are connected to each jack circuit as shown in Table 1. The
upper six terminal blocks are connected to the left interbay jack circuits and the lower six
terminal blocks are connected to the right interbay circuits.

Intermodule Cabling Requirements
4.04 Interbay Patch Module interconnection wires also add to the digital signal losses
depending on the wire length. To assure reliable signal levels, do not exceed 85 feet (26 meters)
including patch cord lengths for each DSX frame.
Cable Types
4.05 The recommended cable type for interconnecting Interbay Patch Modules is 22-26 AWG
shielded twisted pair cable (AT&T 600 C or 1249 equivalent) grounded at one end only.
Interbay Module Cabling
4.06 Interconnect all Interbay Modules, using tie cables to wire-wrap terminals at the back of
each module. Specific wire-wrap terminals are defined on each installation drawing. Atypical
installation drawing is shown in Figure 9. Interbay Patch Modules are normally located in every
fourth bay of DSX-1 and DSX-1C systems as shown in Figure 10.

4.07 Inter module cabling is shown in Figure 10. In single lineups, corresponding circuits 1
through 28 on each Interbay Patch Module are multipled. In double and triple lineups,
corresponding circuits 1 through 14 on each module are multipled in each lineup, and
corresponding circuits 15 through 28 on each module are multipled between lineups.
