LTPH-UM-1234-01 Overview OVERVIEW ® ® The ADC HiGain HDU-409 Lists 1, 2, and 3 are low-power doubler units that extend the range of a HiGain repeaterless T1 transmission system. The doubler units are installed between any doubler-compatible HiGain Line Unit (HLU) and a HiGain Doubler Unit (HDU) or HiGain Remote Unit (HRU). Each doubler allows 1.544 Mbps transmission over an additional Carrier Serving Area (CSA) range. Each CSA with one doubler encompasses approximately 24,000 feet (7.3 km)

The open cover also permits the doubler to be easily distinguished from the 239 T1 repeater.

Applications LTPH-UM-1234-01 APPLICATIONS HiGain doublers operate with any number of other T1, Plain Old Telephone System (POTS), Digital Data Service (DDS), or other HiGain systems sharing the same cable binder group. The HDU-409 can be used in two- to five-span circuits, depending on the models of the HLU and HRU being used with the doubler units and the power option chosen for the HRU. The number of doublers is equal to one less than the number of spans as shown in Figure 6 on page 24.

LTPH-UM-1234-01 PG-Flex Deployment PG-FLEX DEPLOYMENT Figure 2 shows a typical HDU-409 List 2 or List 3 installation for the PG-Flex subscriber carrier system. For each doubler installed between the PG-Flex Central Office Terminal (COT) and Remote Terminal (RT), two auxiliary power pairs are required between the COT and RT. A maximum of two doublers may be installed in a PG-Flex system. Auxiliary Power Pairs Span 2 Span 1 HDU-409 PG-Flex PG-Flex Doubler COT RT HDSL HDSL 9,000' 26 AWG 9,000'

LTPH-UM-1234-01 Generic Information GENERIC INFORMATION This section provides generic information for both the HiGain and PG-Flex applications. DOUBLER ENCLOSURE CAPACITIES WITH FULL SOLAR LOAD The physical location of the doublers is driven by the following three deployment rules: 1 Place the enclosures at the electrical limits (35 dB) of each span. This places the first doubler at the 35 dB location and the second at 70 dB and so on. This allows the maximum circuit range to be realized. C
Résumé du contenu de la page N° 16
Generic Information LTPH-UM-1234-01 3 This rule minimizes power consumption and dissipation from the HLU providing doubler power. It requires the spans closer to the HLU to be as short as possible and the spans farther from the HLU to be as long as 2 possible. This choice minimizes the I R loss in the cable pairs and reduces the thermal stress on the HLU. Only those HRUs that have a local powering option can be used in local HRU-powered applications. The HDU-409 can be housed in a variety o

LTPH-UM-1234-01 Generic Information 1 Always leave at least one empty slot between adjacent doublers. The adjacency rule only applies to the left and right sides of the doubler. The top of one unit can be adjacent to the bottom of another, but should be avoided. Rule 1 does not apply to the HRE-819, the Keptel RF 819, and all enclosures listed in Table 5 on page 12 with Universal Card Cage enclosures. These products have the required slot separations built into their design. 2 Allow as muc
