Fast, Economical, Reliable, and Manageable T1 Deployment

Doubler Units Remote UnitLine Units

ADC’s HiGain® HDSL systems are used by telco providers worldwide to quickly, economically, and
reliably turn up high-speed data, voice and video services. HiGain HDSL provides transport of T1
service over two unconditioned copper pairs at distances up to 12,000 ft/3.6 km on 24 AWG
(0.5 mm) or 9,000 ft/2.7 km on 26 AWG (0.4 mm) per span (up to 5).

HiGain provides extensive diagnostics, including a 4-character real-time display. 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.
