Harris Stratex Eclipse Stratex Eclipse: System components

Indoor

Intelligent Node Unit
The Intelligent Node Unit (INU) enables the wireless node architecture. The modular concept allows a simple terminal to evolve to a complex node thanks to the use of hot-swappable plug-in cards. The INU is available in 1RU (rack unit - height dimension) and 2RU version that respectively support 3 or 6 outdoor units.
Within this INU, all traffic will internally be routed in such a way that all of the external patch pannels and cabling become obsolete.

You can use a number of plug-in cards per INU.

NCC
Node Controller Card: controls whether the node functions well

FAN
Fan card: aircooling of the INU

RAC
Radio Access Card: interface between INU and ODU, works on an intermediate frequency (IF)

DAC
Data Access Card: interface card for the user (Ethernet, E1, DS3, STM1)

NPC
Node Protection Card: takes care of the redundancy of the NCC power supply and the TDM bus

AUX
Auxiliary Service Card: Auxiliary data and alarm inputs/outputs

It is of course possible to put several DAC cards in one and the same INU offering you a very flexible interface to your network. The same applies to the RAC cards to build up a complex node with connections to several locations.

The Ethernet DAC has 4 Ethernet ports that internally are connected to a 4-port switch that supports QoS. When e.g. you would install an 8xE1 E1 DAC and you have a total capacity of 32xE1 (64Mbps), then you can preserve 16 Mbps to 8xE1 and the other 48 Mbps will be divided over the Ethernet interfaces. When you would use two of those, you can preserve 24 Mbps for both channels. Tis is configurable via the software.

Indoor Unit
The Eclipse Indoor Unit (IDU) is a 1RU device fitted for 4/8xE1 or 4/8/16xE1, non-protected (no fail-over), configurations. This unit is suited for dedicated low capacity connections. The IDU can only work with the ODU100.
Outdoor

ODU300
The ODU300 supports all capacities from 4xE1 up to 2xSTM-1 and modulations from QPSK to 128 QAM without the need for hardware adaptations! This implies that the migration between different speeds should be perfectly possible without having someone climbing up the masts with new and expensive hardware. The ODU300 is available in all licensed frequency bands from 5 up to 38 GHz and can only be used together with the INU.

ODU100
The Eclipse ODU100 was optimized for 4xE1 up to 16xE1 with QPSK modulation. This, obviously, is meant for connections that do not require high bandwidths but a reliable, wireless connection. The ODU100 can be used on both the INU and the IDU. Moreover, the ODU100 is incorporated in the same housing as the ODU300, enabling a migration path without the need for new mounting hardware or antennas.
Protected configurations

Eclipse supports 1+1 protected and diversity configurations with one single INU. This INU will then be equipped with two RAC (Radio Access Card) cards, each of which is connected to an ODU and a DAC (Data Access Card). For reasons of redundancy, the INU can be equipped with an NPC enabling redundancy on power supply and NCC (Network Controller Card) level. In order to have hot-stand-by and diversity, there are seamless interchanges between both ODU’s. This also happens when sending data. Space diversity requires two ODU’s, both of which have an antenna. Hot-stand-by and frequency diversity are supported via a direct-mount combiner that combines both ODU’s on one single antenna. The combiner is available with an equal 3 - 3dB split or an unequal 6 - 1,5dB coupler. Space and frequency diversity can be combined in order to represent a hybrid diversity scheme.
