OVERVIEW

The HiGain®Remote Enclosure HRE-425 List 1 houses HiGain line units, doubler units, and remote units (HLUs,

HDUs, and HRUs, respectively). The HRE-425 List 1 can also accommodate a -48 Vdc power supply to power

the slots, if required.

Access to the twelve slots is provided by wire-wrap card-edge connectors or by four 25-pair, type 57, backplane

connectors. An optional RJ48 cable assembly provides access to the DS1 interface through a 12-port harmonic

connector that attaches to either of the remote enclosure’s two side panels or to the top or bottom panels. A variety

of grommited cable access openings are located on the enclosure’s top, bottom, sides, and rear covers.

FEATURES

The HRE-425 List 1 provides the following features:

•12 slots for 12 plugs, or 11 plugs and a -48 Vdc local power supply in slot 12 only

•optional RJ48C or RJ48X modular jack assemblies for DS1 customer interface connections

•printed-circuit backplane provides wire-wrap or connectorized interface wiring options

•tamper-proof locking screw for security

•separate fuses for each slot

•wall, rack, or desktop mounting

•support for T1 (DS1) and E1 (G.703) applications.

APPLICATIONS

HiGain provides a quick and cost-effective way of delivering T1 High Capacity Digital Service (HCDS) to

customers over metallic cable pairs. The primary application of the HRE-425 List 1 Remote Enclosure is to house

the remote units of a HiGain repeaterless T1 transmission system.

Because the HRE-425 uses standard 400 mechanics slots, it can accommodate any plug with

400 mechanics, including the HDU-451 doubler and the HLU-431 line unit. It can also

accommodate 200 mechanic plugs (half the width of 400 mechanics) used by the HiGain

HRU-411 and HRU-402 remote units.

MOUNTING OPTIONS

The HRE-425 is suitable for mounting on a desk top, wall or equipment rack. Before setting up the equipment,

select a location that provides appropriate security. The remote enclosure has four rubber feet for desktop

installations and four mounting holes in the back cover for wall mounting.

Desktop Mounting

The remote enclosure includes four stand-off rubber feet for desktop mounting. When using the unit on a desktop,

take care to prevent blocking the air flow from the bottom of the unit.

Wall Mounting

The backplate of the remote enclosure has four wall mounting holes to simplify wall-mounting. To mount the

enclosure on a wall, remove the backplate and use it as a template for the mounting holes as follows:

1Loosen the four rear-panel locking bolts and remove the backplate (Figure 2).

Figure 2. 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 No. 10 x 3/4inch PHS wood screws

and washers supplied with the remote enclosure.

4Use the four locking bolts loosened in Step 1 as hinge mounting bolts to reattach the backplate to the main

chassis side panels. (See Figure 3 on page 5.)

When the main chassis is attached to the backplate, it can be rotated up or down by removing

the two upper or lower mounting bolts and slightly loosening the two remaining mounting bolts

to allow them to act as hinges. This provides access to the enclosure’s backplane and other

internal areas. See Figure 3 on page 5 for hinging details.
