Rack Mounting
The HRE-425 can be mounted into a 19- or 23-inch relay rack with one of the two rack
mounting brackets that are provided in the installation kit.
Figure 2. Wall Mounting and Hinging View
1Orient the mounting brackets to the side panels consistent with the rack size (19- or
23-inch).
2Attach the rack mounting brackets to the bracket mounting holes (Figure 2) on each
side panel with the four bracket attaching screws and locking nuts.
3Attach the HRE-425 to the rack with the four mounting screws included.
BACKPLANE CONNECTIONS
The HRE-425 List 1 backplane (Figure 3) can be connected in one of the following ways:
•wire-wrap connections to each of the 12 card-edge connectors (J1 through J12)
•terminal block connections to TB1
•25-pair, multiple connectors (P1, P2, P3, and P4)
Figure 3. HRE-425 List 1 Backplane
POWER FUSES AND GROUNDING
Each of the 12 slots are equipped with a 0.5A fuse between the -48 Vdc shelf supply and
pin 35 as shown in Figure 4. This accommodates the maximum power consumption
requirements when using the HRE-425 to house doubler or remote units.
All the fuse alarm contacts are transmitted together on one bus and connected to the Fuse
Alarm, pin 3 of TB1. If a fuse opens, the normally floating Fuse Alarm in pin 3 drives to
-48 Vdc.
When slot 12 is used for an internal -48 Vdc shelf supply, fuse F12 becomes the shelf fuse
and must be replaced by the 2A fuse included in the installation kit. If F12 opens in this
application, the Fuse Alarm is left open and will not be driven to -48 Vdc (as would be the
case if an external power supply were lost).
The internal supply in slot 12 is limited by 2A fuse F12 in order to be compatible with the
maximum current rating of typical, 400 mechanics shelf supplies. This 2A capacity is
sufficient when HRU remote units are used in the other 11 slots but not when HLU-431 line
units are used. An external power supply rated at a minimum of 5A is required to provide
adequate power to a shelf full of HLU-431 line units operating under maximum load. See
the HLU-431 technical practice for additional information.
Figure 4. HRE-425 List 1 Shelf Fusing, Backplane Wiring, and Bus Connections
FIELD SIDE HDSL CONNECTIONS
Connect the HDSL field side ports to the appropriate wire wrap pins of each connector. To
determine slot and pin assignments, refer to the documentation for the product being
installed.
You can also use these connections to access the two HDSL CO side Loop 1 IN and
Loop 2 IN pairs for doubler applications.
The two HDSL facilities access cables that terminate on P3 and P4 provide the necessary
XMT and RCV isolation required if the HRE-425 is used to provide access to standard T1
facilities, suchas when T1 plugs like SmartJack networkinterface devices (NIDs) are used.
Refer to the block diagram on the rear panel for HDSL slot and pin assignments.
CPE DS1 (G.703) CONNECTIONS
Do one of the following:
•Connect the XMT and RCV interfaces to the appropriate wire wrap pins of each
connecter. To determine slot and pin assignments, refer to the documentation for the
product being installed.
•Connect the XMT and RCV interfaces to P1 and P2 connectors.
•Purchase optional 12-port RJ48 harmonic cable assemblies from ADC for the CPE
interface : RJ48C (Part Number 150-2201-01) or RJ48X (Part Number 150-2201-02).
You can attach these cable assemblies to the top, bottom, or either of the two side
panels through the wall mounting holes located on each panel. Figure 1 shows the
locations of these mounting holes on the side panel.
Figure 5. Twelve-Port, Harmonic Cable DS1 Interface Assemblies
TURN-UP
1Open the front panel of the enclosure by loosening the Hex nut at the top, then lower
the panel.
2Insert the card in its assigned slot. Refer to the card’s user manual for complete
information.
Properly ground the HRE case to avoid shock hazard to craft
personnel, bit errors due to noise and crosstalk, and damage
to HRU circuits. ADC recommends that pin 4 of TB1, frame
ground, be connected to earth ground.
The HRE-425 List 1 provides access to frame ground on pins 1
and 27 of each slot connector.

1Orient the mounting brackets to the side panels consistent with the rack size (19- or
23-inch).
2Attach the rack mounting brackets to the bracket mounting holes (Figure 2) on each
side panel with the four bracket attaching screws and locking nuts.
3Attach the HRE-425 to the rack with the four mounting screws included.
BACKPLANE CONNECTIONS
The HRE-425 List 1 backplane (Figure 3) can be connected in one of the following ways:
•wire-wrap connections to each of the 12 card-edge connectors (J1 through J12)
•terminal block connections to TB1
•25-pair, multiple connectors (P1, P2, P3, and P4)
Figure 3. HRE-425 List 1 Backplane
POWER FUSES AND GROUNDING
Each of the 12 slots are equipped with a 0.5A fuse between the -48 Vdc shelf supply and
pin 35 as shown in Figure 4. This accommodates the maximum power consumption
requirements when using the HRE-425 to house doubler or remote units.
All the fuse alarm contacts are transmitted together on one bus and connected to the Fuse
Alarm, pin 3 of TB1. If a fuse opens, the normally floating Fuse Alarm in pin 3 drives to
-48 Vdc.
When slot 12 is used for an internal -48 Vdc shelf supply, fuse F12 becomes the shelf fuse
and must be replaced by the 2A fuse included in the installation kit. If F12 opens in this
application, the Fuse Alarm is left open and will not be driven to -48 Vdc (as would be the
case if an external power supply were lost).
The internal supply in slot 12 is limited by 2A fuse F12 in order to be compatible with the
maximum current rating of typical, 400 mechanics shelf supplies. This 2A capacity is
sufficient when HRU remote units are used in the other 11 slots but not when HLU-431 line
units are used. An external power supply rated at a minimum of 5A is required to provide
adequate power to a shelf full of HLU-431 line units operating under maximum load. See
the HLU-431 technical practice for additional information.
Figure 4. HRE-425 List 1 Shelf Fusing, Backplane Wiring, and Bus Connections
FIELD SIDE HDSL CONNECTIONS
Connect the HDSL field side ports to the appropriate wire wrap pins of each connector. To
determine slot and pin assignments, refer to the documentation for the product being
installed.
You can also use these connections to access the two HDSL CO side Loop 1 IN and
Loop 2 IN pairs for doubler applications.
The two HDSL facilities access cables that terminate on P3 and P4 provide the necessary
XMT and RCV isolation required if the HRE-425 is used to provide access to standard T1
facilities, suchas when T1 plugs like SmartJack networkinterface devices (NIDs) are used.
Refer to the block diagram on the rear panel for HDSL slot and pin assignments.
CPE DS1 (G.703) CONNECTIONS
Do one of the following:
•Connect the XMT and RCV interfaces to the appropriate wire wrap pins of each
connecter. To determine slot and pin assignments, refer to the documentation for the
product being installed.
•Connect the XMT and RCV interfaces to P1 and P2 connectors.
•Purchase optional 12-port RJ48 harmonic cable assemblies from ADC for the CPE
interface : RJ48C (Part Number 150-2201-01) or RJ48X (Part Number 150-2201-02).
You can attach these cable assemblies to the top, bottom, or either of the two side
panels through the wall mounting holes located on each panel. Figure 1 shows the
locations of these mounting holes on the side panel.

TURN-UP
1Open the front panel of the enclosure by loosening the Hex nut at the top, then lower
the panel.
2Insert the card in its assigned slot. Refer to the card’s user manual for complete
information.
Properly ground the HRE case to avoid shock hazard to craft
personnel, bit errors due to noise and crosstalk, and damage
to HRU circuits. ADC recommends that pin 4 of TB1, frame
ground, be connected to earth ground.
The HRE-425 List 1 provides access to frame ground on pins 1
and 27 of each slot connector.

Wall Mounting
1Loosen the four rear-panel locking bolts and remove the backplate (Figure 1).
Figure 1. HRE-425 List 1 Backplate
2Using the backplate as a template, mark the wall locations for drilling the wall
mounting holes.
3Drill pilot holes and attach the backplate to the backboard with the four
#10 x 3/4-inch PHS wood screws and washers supplied.
4Use the four locking bolts loosened in Step 1 as hinge mounting bolts to reattach
the backplate to the chassis side panels. For access to the backplane and other
areas, the chassis can be rotated up or down by removing the two upper or two
lower mounting bolts and slightly loosening the two remaining bolts.
Plugs compatible with the HRE-425 List 1 include:
HLU-431, HLU-432, HDU-404, HDU-451, EDU-451, HRU-402,
H2TU-R-402, and ERU-412. Documentation for these
