Overview

 

 

OVERVIEW

The ADC® HiGain® HDU-409Lists 1, 2, and 3 arelow-powerdoubler units that extend the range of a HiGain repeaterless T1 transmission system. The doubler units are installed between anydoubler-compatibleHiGain 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) using 24 American Wire Gauge (AWG) or 18,000 feet (5.5 km) using

26 AWG loops. Two doublers can triple the CSA range up to 36,000 feet (11 km) using 24 AWG or up to 27,000 feet (8.2 km) using 26 AWG loops. Three doublers extend the 24 AWG range up to 48,000 feet (14.6 km) and four doublers (with a locally-poweredHRU) extend the range up to

60,000 feet (18.3 km). The HDU-409Lists 1, 2, and 3 are identical except that:

The List 1 is only compatible with the HiGain product line.

Lists 2 and 3 are compatible with HiGain and PG-Flex® product lines.

Refer to “PG-Flex Deployment” on page 7 for more information regarding thePG-Flexdoubler applications.

Product Description

 

 

PRODUCTDESCRIPTION

The open-framedcover reduces thermal stress and improves reliability, allowing air to freely circulate over all components. The open cover also permits the doubler to be easily distinguished from the 239 T1 repeater.Figure 1 on page 3 shows the front panel of theHDU-409and

Configuration

For some products the configuration number may contain

number

either a fiveor six-digitwarranty configuration number or a

stand-alonetwoorthree-digitconfiguration number as follows:

Digit 1 - Last digit of shipment year. Digits 2 and 3 - Shipment month.

Digits 4, 5, and 6 - Configuration number.

The configuration number identifies the version of the product. New configuration numbers usually accompany changes in the last two characters of the CLEI code.

The configuration number can also be found on a small bar label that also contains the Julian date code. The configuration number appears as either a stand-aloneCFG xx number or as a15-characternumber comprised of the part number and a3-characterextension. For example, the number150-2404-15-x03is comprised of the part number and an x03 configuration number. This gummed label may be attached to the PC board or to the front panel.

The front panel of the HDU-409contains atri-colorLED. The LED color and activity provides information on system functionality. Table 4 provides a list of all alarm indications in priority order.
