Overview VERVIEW ® ® This document describes the ADC HiGain Outdoor Mini and Micro Doubler Enclosures HRE-819 List 1 and HRE-819 List 2. The primary application 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: •... -
Page 8: Description
Overview 150-819-100-03 ESCRIPTION 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.

Page 10: Enclosure Base
Overview 150-819-100-03 Enclosure Base The HRE-819 enclosure base is a molded plastic unit. The base contains the air bypass 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. -

Page 12: Pressurization
Overview 150-819-100-03 Pressurization Figure 5 shows the pressurization valves. One of the most noticeable external differences between the two enclosures is that the air bypass valve is absent from the gel-core model, HRE-819 List 1. Figure 5. Pressurization Valve Locations Air Bypass Valve List 1 enclosures (gel-filled stub) are intended for above-ground applications and applications requiring the stub to be spliced to non-pressurized, air core cables. -
Page 13: Pressure-Relief Valve And Air Stem
150-819-100-03 Overview Pressure-relief Valve and Air Stem The pressure-relief valve keeps the internal pressure between 12 and 25 PSI. The air stem is a threaded Schraeder valve (similar to a car tire valve) and cap. Use it to pressurize the enclosure from a local pressure source or to measure the enclosure’s internal pressure through a pressure gauge or to relieve the internal pressure prior to opening and removing the cover by removing the air stem valve core (pin). -

Two mounting brackets An HTC-439 ADC test card is included with every HRE-819. This unit is found in a separate box inside the HRE-819 shipping carton. The test card provides an easy-to-use way of accessing and testing the four cable pairs connected to every HRE-819 slot. The test card is provided free of charge for your convenience. -
Page 15: Installing The Enclosure
150-819-100-03 Installation NSTALLING THE NCLOSURE Manhole Installation The enclosure base has mounting brackets with four -inch diameter mounting holes spaced 13- inches vertically by 7- inches horizontally. The hole spacing is consistent with the mounting slot spacing of standard manhole racks. Lower the housing and attached stub cable into the manhole. -
Page 16: Aerial Installation
Installation 150-819-100-03 Aerial Installation To mount the doubler enclosure on a pole, use a 131B T-bracket and mounting bar assembly (ADC Part Number 132-1026-01), as shown in Figure 7. This assembly allows the case to be mounted with the stub cable up or down. -
Page 17: Splicing The Stub Cable
150-819-100-03 Installation Use the -inch lug screw at the bottom to fasten the mounting bar to the T-bracket and to keep the 131B T-bracket vertical on the pole. Lift the case. (The recommended way to lift the case is to use a sling attached through the opening in the doubler enclosure.) Secure the case to the mounting bracket with the four T-bolts. - Page 18 Installation 150-819-100-03 Figure 8. Splice Preparation Before splicing the stub cable to the main cable, test all cable pairs designated for immediate or future use for pair continuity and pair identification. Figure 9.

Page 20: Through-Connecting
Installation 150-819-100-03 HROUGH ONNECTING The method of through-connecting bypasses the housing and connects the pairs through the base. This allows enclosure cable pairs to bypass the housing and be extended through it for access downstream from the HRE-819. Through-connecting is accomplished by mating the 710-type connectors in the base as shown in Figure 11. -
Page 21: Wiring
150-819-100-03 Installation Using a -inch, hand-held, hex nut driver, tighten all bolts according to the sequence stamped on the cover to a torque of 25 to 50 inch-pounds. The torque flattens the lock washers. Do not attempt further tightening. The bolts shear at 125 inch-pounds. Replace the valve core (pin) in the air stem on the base, then connect an air hose having a snap-on chuck to the air stem. - Page 22 Table 2.
