Because they are available in a variety of mechanics (3192, 220, DDM+, LiteSpan, or 200/400) HiGain Line Units (HLU) can be installed in existing managed or unmanaged CO shelves. When ADC HiGain managed shelves (HMS) or HiGain Retrofit Managed Shelves (HRMS) are used, all configuration and performance monitoring can be remotely performed by the Network Operations Center (NOC). HiGain Doubler Units (HDUs) allow HiGain systems to be used for applications outside the Carrier Service Area (CSA), increasing the range by up to five times up to 60 Kft/18 Km on 24 AWG (0.5 mm) or 45 Kft/13.5 Km on 26 AWG (0.4mm). Span equipment consists of HDUs that can be deployed in the existing repeater enclosures or in remote enclosures for higher deployment density and lower deployment costs. Outdoor enclosures from ADC are available for both above and below ground installations. ADC’s HiGain Remote Units (HRUs) are designed to install both indoors and outdoors in a variety of remote enclosures, or on existing remote mountings on or near customer premises. They operate as slaves to the HLU and incorporate loopback functions and LED indications for simple installation and maintenance. The HRUs provide the industry-standard ANSI T1.403 interface toward the customer. • +1-952-938-8080 • 1-800-366-3891 Spec Sheet HiGain® HDSL Fast, Economical, Reliable and Manageable T1 Deployment Features 7/08 • 106669AE HiGain ® HDSL • Up to 5-span reach [60 kft/18 km on 24 AWG (0.5mm) or 45 kft/13.5 km on 26 AWG (0.4mm) see figures 1 and 2] • Lowest power consumption and heat dissipation • Low voltage (<140 VDC) powering of up to two spans (one doubler) • Safest line powering (Class A2 or Class A3) • Ultra-low system delay • BPV transparency for copper-fed DLC support • Stratum 1 clock capable • Full compatibility with the installed base of HiGain systems • Variety of industry-standard mechanics • Front-panel craft ports, DSX-1 test access and status display and provisioning • Comprehensive OAM&P data • NEBS Level 3 and UL/CSA compliance Description Catalog Number Central office line unit, “3192” mechanics HLU-319 L5 Central office line unit, “220” mechanics HLU-231 L8 Central office line unit, “DDM+” mechanics HLU-388 L5 Line unit for LiteSpan 2000, craft port managed, display, option buttons, test access jacks HLU-200 L3A Central office line unit, 200/400 mechanics HLU-432 L1 Central office line unit, 200/400 mechanics with DS1 and HDSL lines reversed HLU-432 L2 Micro doubler, “239” mechanics, single-slot HDU-409 L2A Micro doubler, “200” mechanics HDU-404 L2 Line/local powered, “200” mechanics HRU-402 L1 Ordering Information DSX-1 DS1Line Unit (HLU) remote Unit (HrU) 48 kft on 24 aWG 12 kft 12 kft 12 kft 12 kft HDU HDU HDU Figure 1: Up to 4-Span Extended Reach with all doublers and remotes line powered DSX-1 DS1Line Unit (HLU) Remote Unit (HRU) (-48 VDC LocalPower Required) 60 kft on 24 AWG 12 kft 12 kft 12 kft 12 kft 12 kft HDU HDU HDU HDU Figure 2: 5-Span Extended Rea...
