HRE-819 List 1 and 2 July 9, 1998 1
OVERVIEW
This document describes the ADC®HiGain®Outdoor Mini and Micro Doubler Enclosures HRE-819 List 1 and
HRE-819List 2. The primaryapplication of the HRE-819 enclosure is to house HiGain Doubler units in a HiGain
repeaterless T1 transmission system. The HRE-819 is either a refurbished or originally manufactured AT&T
outdoor enclosure that has been enhanced to house up to:
•Twelve HiGain full-payload, T1 doublers (HDU-439 or HDU-409) or
•Twelve fractional T1 doublers (HDU-219) or
•Twelve 239 T1 repeaters or
•Twelve of any combination of these units
ENHANCED FEATURES
The HRE-819 has enhanced the standard AT&T 819 enclosure case in the following ways:
•Twelve, double-wide T1 239 slots for doublers or T1 repeaters
•Modified single 30-foot stub (54 pair, four group, quad S-screened)
•Enhanced thermal dissipation capabilities
STANDARD FEATURES
•Rack-mount or pole mount capability
•Primary surge suppression across all ports in every slot
•Support for pressure contactor alarm card
The cap, coil, filter, and type B protector functions are not supported.

DESCRIPTION
The HRE-819 List 1 is an AT&T-equivalent 819B1 or 819B2 outdoor enclosure with a gel-filled stub. The
HRE-819 List 2 is an AT&T-equivalent 819A1 or 819A2 outdoor enclosure with an air-filled stub. Figure 1
shows the HRE-819.
Figure 1. HRE-819 Outdoor Doubler Enclosure
Mechanics
The HRE-819 mechanics comply with standard AT&T 819 enclosure cases. The HRE-819 case
(Figure 2 on page 3) is composed of three basic subassemblies:
•An 81-type enclosure base
•A protected 89-type enclosure housing
•Removable access lids
The housing has two separate chambers. Each chamber has six double-wide slots and is accessed by a removable
lid. The HRE-819 family includes two types of lids and four types of bases. Table 1 on page 3 lists the type of
lids and bases and shows which ones are used for the HRE-819 List 1 and the HRE-819 List 2.

Figure 2. Enclosure Base and Housing
You can build the gel-filled List 1 unit with two regular-sized lids (a 2-inch deep, AT&T #842301483) or two
deep-dish lids (a 3.5-inch, AT&T 842301491). The List 1 requires an 81B1-1H base since it does not have an air
bypass valve.
You can build the air-filled List 2 unit only with the 2-inch deep lid and either the single-stub base (81A1-1H) or
a dual-stub base (81A1-1H or 81A2-2H). When you use a dual-stub base, the stub access opening adjacent to the
air cutoff valve is plugged.

Enclosure Base
The HRE-819 enclosure base is a molded plastic unit. The base contains the airbypass valve, pressure relief valve,
order wire port, stub cable, and mounting hardware.
In the event of damage to the housing, the housing can be detached from the base and replaced. This precludes the
need to blow the splice case and resplice a new unit stub into the main feeder cables. Whenever the base and
housing are separated and then reattached, torque the connecting bolts to 40 inch-pounds in the sequence shown
in Figure 3.
Figure 3. Sequence for Torquing the Base Connecting Bolts
Enclosure Housing
The enclosure housing (Figure 4 on page 5) is a molded plastic unit which has two separate chambers. Each
chamber has six double-wide slots and a slot for the maintenance pressure contactor plug. Each plug-in slot
contains connectors that accommodate both the plug-in unit and its associated protectors.
Seal the housing covers to the housing with a reusable gasket, which forms an airtight seal when the lid bolts are
properly torqued to 40 inch-pounds in the sequence inscribed on the lid (Figure 4 on page 5).
