Eclipse Node - Harris Stratex Eclipse 4.6 User Manual

Figure 1-2.
Tributaries are ported on individual RJ-45 connectors and are software configured for
E1 or DS1 operation.
Synchronous or asynchronous auxiliary data and alarm I/O options are included.
Both IDUs may be paired to support 1+1 hot-standby operation. Y cables are used to
provide single-point Tx and Rx tributary connections. Tx and Rx switching is not
hitless.
Requires ODU 300hp, ODU 300ep, or ODU 300sp.
IDU 300 20x and 8x can be over-air interfaced to an Eclipse Node comprising the INU,
DAC 16x and ODU 300. An AUX is included where auxiliary channel services are also
required. This applies only to non-protected 1+0 link operation. Where 1+1 IDU
operation is required, protected IDUs must be installed at both link ends.
IDU300 20xV2
IDU 300 20xV2 supports 20 tributaries on individual RJ-45 connectors for E1 or DS1
operation, modulation options to 128 QAM, and over-air capacities to 40xE1 or
32xDS1. Features include:
• Capacities to 20xE1 / 16xDS1 for single link non-protected operation.
• Capacities to 20xE1 or 16xDS1 for hot-standby or space diversity operation.
• Capacities to 40xE1 or 32xDS1 for hot-standby operation.
• IDUs are paired for protected/diversity operation.
• For capacities to 20xE1 / 16xDS1 normal IDU equipment and path protection
applies, with Y cables used on the tribs.
• For higher capacities, traffic from the standby IDU is routed to the online IDU to
support termination of up to 40xE1 or 32xDS1 tribs. In this configuration trib and
PSU protection is not supported, however RAC/ODU and path protection
functions are retained.
• Tx switching is not hitless.
• Rx path switching (voting) is hitless (errorless) for capacities to 20xE1 /16xDS1.
It is not hitless when configured for 40xE1 / 32xDS1 operation.

IDU 300 20xV2 is capacity licensed. The base configuration supports 20xE1/16xDS1,
with capacities to 40xE1 or 32xDS1 obtained by requesting additional capacity
upgrades at time of order or as field-downloadable software licenses. See
20xV2 License and Steps on page 5-7
Synchronous or asynchronous auxiliary data and alarm I/O options are included.
Requires ODU 300ep, ODU 300hp, or ODU 300sp.
