Chapter 1. System Overview
Capacity is licensed. The base configuration (no license required) supports 20xE1 or
20xDS1 circuits. The licensed extensions enable Ethernet in steps to 50, 100, 150, 200,
or 360 Mbps, each with up to 20xE1 or 20xDS1 waysides.
Protected 1+1 hot-standby or space diversity operation is configured by adding a
second IDU GE 20x. Ethernet traffic is supported on a single interface to one of the
IDUs. E1/DS1 traffic is supported on interfaces to both IDUs using Y-cables.
The 1RU IDU GE 20x complies with ETSI half-rack mechanical specifications with a
rack depth of 240 mm (9.4").
Figure 1-7.
IDU GE 20x is also available in a 'Connect' link package, where a package comprises
two terminals, each with one IDU GE 20x, and one ODU 300 outdoor unit, which
depending on the required throughput and band, can be ODU 300sp, hp or ep.
Alarm I/O options are included.
An IDU GE 20x 1+0 terminal can be over-air interfaced to an Eclipse Node comprising
the INU, RAC 30 or RAC 3X, DAC GE or DAC ES, and ODU 300. Where E1 or DS1 side
channels are required, a DAC 4x or DAC 16x is included. Similarly an AUX is included
where external Alarm I/O interfaces are required.
For protected IDU GE 20x operation, both ends of the link must be IDU GE 20x.
Eclipse Node
Eclipse Node replaces the traditional terminal or single-link based approach to
networking with a nodal solution. One Eclipse platform directly supports up to six
links, on frequency bands from 5 to 38 GHz.
Radio paths and customer interfaces are customized by plug-in cards. A high-speed
backplane bus provides traffic and services interconnection.
The figure below shows an Eclipse Node comprising an INU (Indoor Node Unit) with
three ODUs.
