WorldDSL™ HDSL
Economical, Reliable, and Manageable E1 and Serial Data Deployment
Line and Universal Terminating Units
Element Doubler Unit
ADC's WorldDSL™ HDSL Solutions are designed for the copper cable-based E1 (G.703) and Serial
data (V.35, V.36,RS-530, and X.21) access needs of Global markets and are ideal for both telco
and enterprise networks. WorldDSL HDSL Line and Universal Terminating Units can be used
in a managed central office (CO) or enterprise data-center based type chassis or in single slot
enclosures. WorldDSL HDSL Element Doubler Units are used outdoors between the central office
and the customer to extend the range and reach of HDSL when needed.
WorldDSL HDSL is part of a fully manageable system. Using a VT100 compatible terminal or a PC,
the units can be managed via their local craft ports. When used in a WorldDSL Element Managed
Shelf (EMS) and an Element Management Unit (EMU), the entire system can be managed locally or
remotely through a dial-up modem or Ethernet network.
The HDSL line cards come in span powering Line Terminating Unit (LTU) and Universal Terminating
Unit (UTU) versions. The LTU central office unit is locally powered and can span power a remote
UTU version. The UTU card can be used universally as a locally powered CO/LTU or as a local or
span powered remote/Network Terminating Unit (NTU). LTUs and UTUs can be mounted in a
16-slot EMS or a single slot Element Remote Enclosure (ERE).
The WorldDSL HDSL Element Doubler Unit (EDU) can be used to greatly increase the service area
range. The EDU is line powered by a WorldDSL LTU. Up to two EDUs can be installed in a circuit,
each of which will extend the reach of the circuit. For example, if, based on the current circuit
noise and wire gauge, the reach is 3.2 Km, adding one EDU can extend reach to 6.9 Km and a
second can extend reach to 7.5 Km. The EDU is suitable for outdoor use and is mounted in one of
ADC's weatherproof enclosures such as the single HRE-602 (holds one EDU) or Radiator (holds 6
to 8 EDUs). The EDU features a front panel LED for easy verification of operation during installation
and troubleshooting that is externally visible when used with the HRE-602 enclosure. ADC's
doubler enclosures also feature integrated gas tubes for lightning and power cross protection.
