GENERAL
The DSXi DSX-1 products are designed to offer customers greater density and flexibility in an
easier-to-use better designed product format. DSXi panels are offered in a variety of
configurations, including four cross-connect options, various heights and widths, circuit densities,
labeling formats, and equipment connections. DSXi products use industry standard accessories
(patch cords, plugs, etc.) and mount in industry standard EIA and WECO racks and bays.
All rear cross-connect panels have front jack field access with the equipment cabling and crossconnect fields on the rear of the panel. All front cross-connect panels have jack field and crossconnect fields on the front of the panel with the equipment cabling on the rear. Finally, all total
front access panels have the jack field, cross-connect field, and equipment cabling on the front
of the panel.

ADCP-80-535 • Issue 1 • January 2002
Within the front cross-connect panel family, there are two specific options: front-split and frontbelow cross-connect. Every front-split panel has the cross-connect field located on either side of
the jack field, half on the left side and half on the right side. The front-below panel has the
cross-connect field located below the jack field.
On all total front access panels, the input/output cabling field is located below the jack field,
while the cross connect field is split on either side of the jack field.
DSXi panels are available in configurations consisting of two widths, three heights, four crossconnect formats, four circuit densities, two impedance load ratings, and two circuit labeling
formats. DSXi panels are available in circuit densities of 56, 60, 64 and 84. These are shown in
Table 1. Each panel is equipped with vertical circuit identification strips and is designed for
universal mounting in either EIA or WECO mounting racks. The panel can be mounted flush, or
with a two, three, or four inch recess.

• Humidity: 10% to 95% relative humidity without condensation.
2.2
Unpacking and Inspection
The DSXi panel and accessory package are packaged separately for protection during shipping.
Remove all items from their shipping containers. Verify that all parts on the packing slip have
been received before discarding the shipping containers. If there are any damaged or missing
parts file a claim with the commercial carrier and notify ADC.
2.2.1
Panel Positioning and Mounting
The accessory package contains screws, mounting brackets, cable rings, installation drawing, etc.
Mounting brackets are installed on the panels before locating them in their assigned bay positions.
A maximum of 14 DSXi Panels may be installed in a seven foot rack with a fifteen inch footprint.
Ten to eleven DSXi panels may be installed in a seven foot rack with a twelve inch footprint.
When installing DSXi Panels in a raised floor environment, add the panels in the bay in a top to
bottom order. When using a solid floor environment (over-head cabling), work in a bottom to
top order. Install each DSXi Panel as follows:
1. Determine the new panel position in the bay.
2. Determine recess in the rack. Panel can be mounted flush or with 2, 3, or 4-inch recess.
Remove mounting brackets and reposition as necessary.
3. Secure panel in place with screws through the upper and lower mounting holes of the panel.
4. On front cross-connect panels position cable ring mounting brackets and cable rings on the
panel and tighten mounting screws. Cable rings may already be installed on rear crossconnect panels, if not install them at this time.
5. Rack filler panels are required between the DSXi racks. A 5-inch rack filler panel is
recommended for installations using 56 to 64 position panels. A 7.5-inch rack filler panel
is recommended for installations using 84 position panels.

SYSTEM WIRING AND CABLING
Wiring and cabling the DSXi System into the office requires connection of office power and
ground, wiring of cross-aisle and interbay patching panels, cabling of network element input/
output circuits, and installation of all cross-connect jumpers. The following paragraphs give
procedures for installing the wiring and cabling.
Caution: All DSX wiring and cabling should be connected with the system office battery input
off or disconnected at the office distribution panel.
3.1
Power Wiring
The DSXi System operates on –48 Vdc filtered office battery, fused or breakered at the office
distribution panel. Approximate current requirements can be calculated based on one flashing
LED (Bantam) drawing 0.01 Amps.
The number of LEDs lit at any one time will depend on local patching and testing procedures. It
is recommended that individual DSXi panels be fused at the fuse panel with a 0.5 Amp fuse and
connected to the fuse panel using 24 AWG solid copper wire. Each fuse panel dedicated to an
individual DSXi bay serving only tracer lamps and LEDs should be connected with solid copper
wires to the office battery supply and fused with a 3.0 Amp fuse.
DSXi Panels have power and ground terminal strips or blocks located at either the front or rear
of the panel to provide connection to the office battery and ground. Typical configurations are
shown in Figure 1 and Figure 2. Connect office battery and ground to the DSXi Panels as
follows:
• Connect –48 Vdc office battery to the –48 V terminal on the terminal strip/block.
• Connect –48 Vdc office battery return to the RTN terminal on the terminal strip.
• Connect office frame ground to the GND terminal, follow local grounding practices. This
is the recommended chassis grounding procedure.
Note: The metal strap between the GND (chassis ground) and SG (shield ground)
terminals may be removed to isolate shield ground from chassis ground.
• Connect the –48 Vdc office battery from the DSXi panel to the NEG (–) BUS terminal on
the fuse panel. Match fuse position one to panel one, fuse position two to panel two, etc.
• Connect the office battery return (ground) from the DSXi panel to the POS (+) BUS
terminal on the fuse panel.
ADC fuse panel busses are typically rated at 50 to 70 Amps. The size of the feeder wires
between the fuse panel and the office battery should be calculated based on anticipated overall
bay equipage and use of the fuse panel.
Each fuse panel may be connected to a remote fuse alarm system. If this option is desired,
connect the office fuse alarm system to the two REMOTE ALARM terminals on the fuse panel.
A closure (dry loop) will be provided across these two terminals in the fuse panel whenever a
fuse is activated.

Cabling and Cross-Connect Wiring
3.2.1
Installation Drawings
All bays, chassis, modules, and panels are shipped with installation drawings. These drawings
define the specific input/output and cross-connect terminals wired to each DSX circuit and
front-panel jack.
3.2.2
Cable Routing
Note: To maximize cable density in the DSXi bay careful attention to cable dressing is
critical. All cables must be neatly and securely tied or laced in place to prevent over
crowding in the verticalduct area of the rack.
DSXi Systems are wired to the network element by means of cables at the front or rear of each
bay, depending upon the access specified. All cabling should be in accordance with local
practices.
Page 6

ADCP-80-535 • Issue 1 • January 2002
If cables are entering the bay from above, cable attachment should start with the bottom panel and
work up. If the cables are coming from below, cable attachment should begin at the top.
All cables should be secured to brackets at the rear of the bay or within the duct (unequal flange
bays). The cable jacket should be stripped from an area past the last tie on the cable bracket at a
level about even with the wire-wrap pins to which the wires will be connected. A six-inch service
loop should be left before the cable is routed to the wire-wrap terminals.
3.2.3
Network Element Cabling
Using cables and wire-wrap tools, connect the network element to their designated DSX input/
output terminations. Typical connections are defined in the installation drawings accompanying
the DSXi equipment. Terminate cabling for each network element receive to one pair of IN
wire-wrap terminals, and each transmit to one pair of OUT wire-wrap terminals.
3.2.4
Cross-Aisle Panel Cabling
Cross-aisle tie cables between lineups in DS1 and DSXi systems should be connected in a
manner similar to Figure 3 or Figure 4. Connect the tie cables to the wire-wrap terminals on the
rear of the cross-aisle panels as defined in the installation drawing. The OUT terminals of the
originating cross-aisle panel connect to the IN terminals of the terminating cross-aisle panel,
and the IN terminals of the originating cross-aisle panel connect to the OUT terminals of the
terminating cross-aisle panel.

Interbay Patching Panel Cabling
Connect all Interbay Patching Panels using tie cables to wire-wrap terminals at the back of each
panel. Specific wire-wrap terminals are defined in the installation drawing. Interbay patching
panels are normally located in every fourth bay of DS1 and DSXi systems as shown in Figure 5.
Recommended interpanel cabling is also shown in Figure 5. The wire-wrap terminals
designated LEFT should be cabled to the preceding interbay panel, and the terminals designated
RIGHT should be cabled to the succeeding interbay panel.

Cross-Connect Wiring
Cross-connect jumpers should be routed as shown in Figure 6 and Figure 7. All cross-connect
jumpers should use the horizontal wireways between bays, and the vertical wireways within the
bay. Whenever a jumper changes direction, it should do so where a ring, tray or fanning strip is
located. This will allow the jumpers to be dressed neatly without strain or interfering with other
jumpers. All discontinued jumpers should be removed from the DSX wireways, to prevent
unnecessary buildup and congestion.

DSXi Cross Connects
Using five-conductor 24 AWG jumpers, cross-connect DSXi circuits as shown in Figure 7.
Terminal identification is as shown in the installation drawing accompanying each panel.
• Connect the TL of the first termination to the TL of the second termination (green wire).
• Connect the OUT of the first termination to the IN of the second termination (blue wire
and blue and white wire).
• Connect the IN of the first termination to the OUT of the second termination (orange wire
and orange and white wire).
Remove any discontinued jumper by disconnecting each end and cutting off the bare ends.
Remove each end of the jumper from the vertical wireways, and carefully remove the jumper
from the horizontal wireway by pulling at either end. This method will allow the jumper to be
removed without snagging or placing undue strain on the remaining jumpers.
