IDU GE 20x Compatibility
IDU GE 20x can be over-air interfaced to:
• INU/INUe fitted with a RAC 30v3, RAC30A [non-adaptive modulation] or RAC 3X.
For ETSI bands it also applies to RAC 30v2+.
• Ethernet traffic is terminated on a DAC GE or DAC ES.
• E1/DS1 traffic is terminated on a DAC 16x or DAC 4x.
• External alarm I/O interfaces are terminated on an AUX.
• IDU ES for Ethernet and up to 8xE1.
• IDU 300 20xV2 for up to 20xE1 only.
Table 1-6 shows compatibility for ETSI rates.
Table 1-7 shows compatibility for ANSI rates.

2. Over-air compatibility for like capacity with other Terminals and/or Eclipse Node (INU/INUe + ODU). IDU E1/
DS1 tribs are end-end compatible with INU DAC 4x and DAC 16x plug-ins. The auxiliary function provided on
IDUs is end-end compatible with the INU/INUe AUX plug-in. Over-air interoperability is supported between
ODU 300ep and hp; ODU 300sp is only interoperable with another ODU 300sp. IDU-to-INU compatibility
does not apply to protected operation; where protected IDUs are to be installed they must be at both
ends of the link.
3. Compatibility includes RAC 30v2 from SW release 3.5 (RAC 30v3 compatible mode). Applies to ETSI rates
only.
