1. GENERAL
1.1 Document Purpose
This document describes the Westell RJ48C (Issue 2) Series of
Jack Interface Panels. An RJ48C jack panel is shown in
Figure 1. See Table 3 for specific model numbers and descrip
tions.
1.2 Document Status
Revision C of this practice updates Paragraphs 1.3, 2.2.1,
Figure 3, deletes the previous Figure 4, Table 2, and Table 5,
and adds the current Table 2 and Figure 4 through Figure 6.
Revision B of this practice updated all text and drawings which
describe or show the mounting ears (additional holes added).
Revision A replaced 030‐101336 for the models shown in
Table 3 and updated the company contact information. Prac
tice 030‐101336 replaced practice 057‐017701. Whenever this
practice is updated, the reason will be stated in this paragraph.
1.3 Product Purpose and Description
The RJ48C‐28I2 and RJ48C‐28BAI2 28‐position T1 jack pan
els provide easy Customer Interface (CI) connections for
operation in 1.544Mbps High‐capacity Digital Services (Hi‐Cap)
applications. Provided at the front of the jack panel are 28
RJ48C jacks for customer connections. At the rear are two,
64‐pin, male, Amphenol connectors for Customer or Network
connections. Two, 64‐pin, female, Amphenol‐type cables are
needed (provided with the RJ48C‐28I2 model only) to inter
face the panel with the nearby shelf assembly. See Table 3 for
ordering information for the panels and various cables.
1.4 Mounting Location
The jack panel may be mounted in a 19” or 23” relay rack or on
a wall. The panel occupies 2 Rack Units (RUs) or 3.5” of verti
cal space and is mounted above or below a 31MA228 or
DSA‐2280I3 shelf assembly. It also may be mounted facing the
circuit‐card side or the wire‐side of the shelf assembly.
1.5 Product Features
The jack panel offers the following features.
SMounts in a 19” or 23” relay rack (2 RUs) or on a wall
SDetachable and reversible mounting ears allow wall or rack
mounting, and either flush or projected rack orientations
STwo, 64‐pin, male connectors at the rear of the panel allow
Customer Interface (CI) or Network Interface (NI) con
nections to the nearby shelf assembly

2. INSTALLATION
Installation consists of inspecting the equipment for damages,
following proper safety precautions, attaching the mounting
ears in the correct position for the desired mounting type,
mounting the jack panel in a rack or on a wall, and connecting
cables per company practice.
‐ INSPECTION NOTE ‐
Visually inspect the unit for damage prior to installation. If the
equipment was damaged in transit, immediately report the damage
to the transportation company and to Westell (see Part 6).
‐ PRECAUTIONARY STATEMENT ‐
Never install telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
Use caution when installing or modifying telephone lines.
2.1 Jack Panel Installation
There are two mounting types; one is rack mounting and the
other is wall mounting. See Table 1 for a step‐by‐step installa
tion procedure and refer to Figure 3 if needed.
2.1.1 Rack Mounting
The jack panel can be mounted in both 19” and 23” relay racks.
The panel ships with the ears attached in the 23” rack mount
position. The mounting ears may be detached from the panel,
reversed, and re‐attached for 19” rack mounting.
2.1.2 Wall Mounting
The jack panel may be mounted on a wall. It is recommended
that local company practices be followed for wall mounting and
that ½‐inch or ¾‐inch plywood be mounted to the wall prior to
installing the panel. For best cable access and hand mobility, at
tach the 64‐pin cables and secure cable ties prior to mounting

Section RJ4‐8C0‐202 030‐101676 Rev. C R
21012I2RC
to the wall. The mounting ears may be detached (panel is
shipped with ears in the 23” rack mount position, as shown in
Figure 3), re‐positioned, and re‐attached for wall mounting ap
plications.
Step Mounting Task/Description
1. Unpack/inspect. Unpack the unit and determine if it has been
damaged. See return instructions in Paragraph 5.2.
2. Get tools. Gather all mounting hardware and tools.
3. Determine mounting type and ear position. The panel is shipped
with the ears attached for projected mounting in a 23” relay rack (see
Figure 3). If flush mounting in a 23” rack is desired, or if either 19”
rack or wall mounting is desired, remove, re‐adjust, and re‐attach
the ears in the desired position, as explained below.
4. Attach ears per correct mounting type. First detach the ears by
removing the two screws that secure each ear.
For projected 23” rack mounting, do not remove the ears.
For a flush 23” rack mounting, move the ears further forward on the
side of the panel. Align the holes in the ear's short flange with the
front‐most set of holes on the side of the panel, insert and thread the
screws through the aligned holes, then tighten the screws.
For 19” rack mounting, flip the removed ears so that the long flange
of the L‐shaped ear is against or abuts the side of the panel. If flush
mounting within the rack is desired, align the front‐most holes in the
ear's long flange with the front‐most set of holes in the side of the
panel. If a projected mounting position in the rack is desired, align
the holes in the ear's long flange with the rear‐most set of holes in
the side of the panel. When the holes are aligned, insert and thread
the screws through the aligned holes. Tighten the screws.
For wall mounting, any ear position (or hole set) may be selected,
per company practice and application and for the best cable access.
Align the selected ear holes with the selected holes in the side of the
panel, then thread and tighten the screws.
5. Ground panel. Use ground lug on inside wall to ground the panel.
6. For wall mounting only, attach 64‐pin cables then mount to wall.
Remove the 64‐pin connector covers at the back of the panel. Install
the 64‐pin cables at the back of the panel. Route cables through the
large cable access hole in the side of the panel, if needed. Secure
cables with cable ties. Last, mount panel to wall per local practice.
7. For rack‐mounting, mount to rack then attach 64‐pin cables.
Mount the panel to the desired 2RU rack position. Remove the 64‐pin
connector covers at the back of the panel. Install the 64‐pin cables at
the back of the panel. Route cables through the large cable access
hole in the side of the panel if needed. Secure cables with cable ties.
8. Install RJ48C cables. Install all required RJ48C cables at the front
of the panel, per company practice, and label all connections.
Table 1. Step‐by‐Step Installation
2.2 Installer Connections
2.2.1 Signal Connections
Connections are made at the front of the panel to the RJ48C
jacks, and at the rear of the panel at 64‐pin connectors. See

Table 2 for the jack panel's jack and connector pin‐outs. The
RJ48C Jacks on the front of the Jack panel provide the customer
interface. The 64 pin connectors on the rear of the panel provide
the interface to the network. The 64 pin connector labeled XMT
is signal from the network to the customer equipment (AZ).
The 64 pin connector labeled RCV is signal from the customer
equipment to the network (ZA).
2.2.2 Power and Ground Connections
No power connections are required. A chassis ground is pro
vided via metal to metal contact.
3. TESTING & TROUBLESHOOTING
3.1 Testing
Initial testing consists of performing the procedures indicated
for the plug‐ins installed in the shelf assembly. If trouble is en
countered, verify all installer connections to the assembly, that
no fuse is blown, and that modules are properly inserted.
This equipment should not be field repaired. If the equipment
is suspected of being faulty, replace it with another unit and re
test. If the replacement appears to operate correctly, the
original may be faulty and may be returned to Westell for repair
or replacement (see Paragraph 5.2).
3.2 Troubleshooting
If trouble is encountered, verify all connections to the panel
and to the assembly. If trouble persists, replace the suspect unit
and repeat procedures outlined. These procedures are not de
signed to effect repairs or modifications. Any tests beyond
those outlined herein, or repairs made beyond replacing a
faulty unit, are not recommended and may void the warranty.
