Chapter 2. Eclipse Terminals
For the SDH IDU 155o, the 128 QAM and 64 QAM modulation options support ETSI
and ANSI channel bandwidths, but for 16 QAM the resulting 55 MHz bandwidth is only
applicable on ETSI bands.

PDH Trib Ports
Tribs on all 300 series PDH IDUs are on individual RJ-45 connectors.
• E1 trib options are 75 ohm unbalanced or 120 ohms balanced.
• DS1 trib encoding options are AMI or B8ZS. Line impedance is fixed at 100 ohms
balanced and line length is selectable.
Trib cable options include:
• An RJ-45 to 2xBNC cable assembly.
• An RJ-45 to RJ-45 straight cable assembly for extension to an RJ-45 patch panel.
• An RJ-45 to RJ-45 cross-over cable assembly for use between IDUs at repeater or
branch sites.
• An RJ-45 to wire-wrap cable assembly.
• Splitter Y-cables for protected hot-standby operation.
For more information on cable assemblies and connector pin-outs refer to
Appendix D.
