Flashing Yellow about once per second Indicates a Network Doubler Unit (NDU) loopback is in effect in the HDU-409 towards the network.
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.
PG-Flex Deployment LTPH-UM-1234-01 With two doublers, four sets of auxiliary power pairs must be installed between COT and the RT. These auxiliary power pairs must be the same wire gauge (or larger) as the pairs used for HDSL and power. Auxiliary Power Pairs PG-Flex COT Span 1 HDSL Doubler 1 HDU-409-L2 HDU-409-L3 Span 2 HDSL Doubler 2 HDU-409 L2 HDU-409-L3 Span 3 HDSL PG-Flex RT H0075-A Figure 3. Two Doubler HDU Installation with PG-Flex PG-Flex systems do not support doubler loopbacks.
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.
Generic Information 3 LTPH-UM-1234-01 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 possible. This choice minimizes the I2R 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.
LTPH-UM-1234-01 1 Generic Information 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.

Generic Information LTPH-UM-1234-01 ALTERNATIVE DOUBLER ENCLOSURE CAPACITIES Reduce the doubler capacity by one for every two doublers that do not have an empty slot between them. If the application allows seven doublers, but two are directly adjacent to each other, then the total capacity must be reduced to six. Standard T1 or LD1 repeaters can be installed in the same enclosure with doubler units.
LTPH-UM-1234-01 Generic Information The AT&T 819 enclosure has two, individual isolated chambers as shown in Figure 4. Slots 1 through 14 are in one chamber. The other chamber contains slots 15 through 25, along with the Pressure (PRES), Filter (FIL), Capacitor (CAP), and COIL slots. .

Generic Information LTPH-UM-1234-01 MIXING HIGAIN DOUBLERS The HiGain HDU-439 mini doubler can also be installed along with the HDU-409 micro doubler in the same enclosure. Assign a thermal weight of 1.5 HDU-409 for every HDU-439 and round down to the nearest whole number. This results in one of the following thermal relationships: a) 1.
LTPH-UM-1234-01 Generic Information 4 For non-solar applications in an environment up to 95°F maximum, the capacity for an SPC, 32-slot 7030-32P enclosure can be increased to all 32 slots. 5 Decrease capacities in Table 5 and Table 6 on page 15 by five percent (round up to the nearest whole number) for every 5°F (2.8°C) increase, or fraction thereof, in ambient temperatures above 115°F (46°C). Always assign the empty slots to the highest (uppermost) positions.
Installation LTPH-UM-1234-01 INSTALLATION To install the HDU-409 in an enclosure, perform the following steps and refer to the enclosure installation manual for information about cabling, proper connections, grounding, and line and local power (see “Documentation” on page iii). This product incorporates static sensitive components. Proper electrostatic discharge procedures must be followed. Enclosure H0081-A STA TU S HDU Figure 5.
LTPH-UM-1234-01 Installation 1 To install the doubler unit, slide the doubler unit into the card guides for the desired slot (see Figure 5 on page 20). 2 Next, push the unit into the enclosure until it is seated in the card-edge connector. The unit snaps into place, indicating that it is properly seated. Once the HDU-409 is installed in the enclosure, the front panel Status LED flashes green to indicate power is applied from an upstream line unit.
Loopback Operation in HiGain Systems LTPH-UM-1234-01 LOOPBACK OPERATION IN HIGAIN SYSTEMS Doubler loopbacks work only with HiGain systems. PG-Flex does not support doubler loopbacks. When equipped with the HDU-409 a HiGain system can execute the types of loopbacks listed in Table 7.
LTPH-UM-1234-01 Loopback Operation in HiGain Systems The SPLB generic command set for four-doubler loopbacks is listed in Table 7. The commands are specific combinations of either 6 or 7 bits that continuously repeat. All NDUx loopbacks are towards the network. All CDUx loopbacks are towards the customer. Figure 6 on page 24 is a diagram of the various HiGain loopbacks. Table 7.

LTPH-UM-1234-01 Appendix A - Functional Description APPENDIX A - FUNCTIONAL DESCRIPTION HiGain uses the ADC Two-Binary, One-Quaternary (2B1Q) HDSL transceiver system to establish two full-duplex 784 kbps data channels between the HLU, HDU, and HRU units. Each HDU-409 increases the maximum range by approximately 12,000 feet (3.7 km) using 24 AWG or 9,000 feet (2.75 km) using 26 AWG per doubler. See Table 2 on page 3 for deployment rules.
Appendix A - Functional Description LTPH-UM-1234-01 Table 8 on page 26 provides a guide for the loss that occurs when using various cable gauges at 196 kHz and 135Ω. It applies to the HDSL cable pairs between the COT and the HDU, and between the HDU and the RT. To achieve optimum performance, make the electrical length (196 kHz loss) of all HDU spans as close to equal as possible. This results in the highest operating loop margins.
