Page 9: Overview
HiGain HRE-506 List 1 (gel-filled) and List 2 (air-filled) are outdoor, stainless steel, weatherproof enclosures designed to house up to six HiGain remote or doubler units. The HRE-506 is part of a HiGain system. EATURES The following features are included on the HRE-506 weatherproof enclosures: •... -
Page 10: Pressurized Applications
PPLICATIONS For pressurized applications on the HRE-506, the Schrader air stem valve is used. A pressure gauge attaches to the valve for the purpose of measuring the internal pressure of the enclosure. This valve is also used to relieve the internal pressure prior to opening and removing the dome cover. -
Page 11: Metal Valves
150-506-100-03 Overview An optional breather vent assembly is enclosed in the air-filled HRE-506 List 2 shipping kit. The kit is a small plastic bag attached to a red and brown colored spare pairs shrink tube. The breather vent replaces the pressure-relief valve, if the air-filled unit is not pressurized. -
Page 12: Functional Description
Gel-Filled Unit The gel-filled HRE-506 List 1 unit is equipped with three metal valves installed in the base section, as shown in Figure 3 on page 5. The gel-filled screened 28-pair, 24 American Wire Gauge (AWG) cable stub on the gel-filled unit is equivalent to an ALP FTS-PIC filled-core telephone cable. -
Page 13: Air-Filled Stub Unit
The cable complies with the requirements of ANSI/ICEA S-85-625-1996 and REA PE-22. The HRE-506 cable sealing, O-ring, and V-Band seal have been safely tested to 36 pounds per square inch (PSI). Most cables become ruptured or damaged at this pressure level. However, the HRE-506 cable sealing is designed to handle this amount of pressure. - Page 14 The common pressure supplied through the cable is approximately 9 PSI. This is sufficient to prevent water from entering the cable or housing. ADC recommends pressurizing the enclosure to a maximum of 12 PSI. To avoid pressure buildup, the pressure relief valve is set to release air at a maximum pressure of 15 PSI.

-inch nonmetallic washers. Nonmetallic washers are required to avoid a ground loop that may result if both the rack and the enclosure are grounded. ADC does not recommend using the rack ground for the enclosure ground since its integrity is not 100 percent reliable. -
Page 22: Grounding
“Grounding a Pole Mounted Enclosure” below. The HRE-506 requires a resistance of 25 Ω or less to ground as measured with a Megger-type ohmmeter. The 8 MIL aluminum shield on the stub is connected to the card cage mounting brackets by a braided shield ground wire. - Page 23 If the resistance requirement is not met, ground the main cable shield every 2,000 ft (610 m).

Page 35: Lightning Protection Unit
The LPU is used primarily for protecting the HDSL loops and customer T1 circuits. All HRE-506 units are equipped with four LPUs. Each LPU contains four gas tubes that provide surge protection to the four ports in each slot. The tubes have three leads that provide protection from Tip and Ring to ground. The ground pin is connected to Pin 1 of each slot. -
Page 36: Cable Stub And Pressurization
Table 3 on page 31 a complete description of the cable stub. The stub is available as HRE-506 List 1 (gel-filled) or List 2 (air-filled). The stub is secured to the enclosure baseplate by a cable strain relief adapter. The cable pair is splayed and encapsulated in the polyurethane that is poured into the enclosure base. -

The optional pressure relief valve is included in the shipping kit. The HRE-506 List 1 comes with a gel-filled cable, which precludes pressurizing through the cable stub. -
Page 38: Spare Connections
ADC. Spare Connections The HRE-506 stub has three spare pairs and one order wire pair. One spare pair and the order wire pair are in the blue group. The remaining two spares are in the orange group. Order Wire Connections The external order wire pair access port is connected to its surge protector by the red-brown jumper wire. -

Page 41: General Deployment Rules
HRE-506 deployment rules. Even when the deployment rules are followed, the metal surfaces of the installed units can feel hot to the touch when removed from an HRE-506 that is operating in elevated ambient temperatures. These conditions are normal for the plugs operating under these circumstances. The plugs were designed to withstand these elevated temperatures. - Page 42 Appendix B: Additional Information 150-506-100-03 The physical location of the HRE-506 doubler enclosures is driven by one of three deployment rules: Rule 1 The first and most important rule is to place each enclosure span to the electrical limits of 35 dB. This places the first doubler at the 35 dB location, the second at 70 dB, and the third at 105 dB.

Page 43: Splicing
150-506-100-03 Appendix B: Additional Information PLICING Splicing consists of connecting the wire pairs of the HRE-506 cable stub to the main cable located in the splice case, as shown in Figure 15 below. The following sections contain step-by-step procedures for: •... -
Page 44: Splicing Procedure
Keep cable pairs dry and cover the exposed splice to protect it from the elements if it is left unattended prior to completion. Splicing Procedure Certain applications involve splicing the cables on the HRE-506. The following section describes splicing procedures and wire list information. Splice the cable stub to the main cable using the wire identification information in Table 3 on page Visually inspect each splice for split pairs, opens, and shorts. -
Page 45: Post-Splicing Procedure
Roll back and tape the screen divider from the cable stub. Perform any cable tests required by local practice. ADC highly recommends that you maintain cable pair integrity on the HDSL and T1/G.703 sides. Post-Splicing Procedure The post-splice procedure involves the following steps:... - Page 46 Fold the screen divider back on itself several times and tape it to prevent it from unfolding. Position the folded, taped screen divider between the spliced and taped Group 1 and Group 2 pairs. Seal and close the splice case, according to the splice case instructions.
