Integrated Headend Unit (IHU)
IHU will host the following modules:
1. RIX - Radio Interface Expander; RF interface to OIX module
2. RIM - Radio Interface Module; RF source conditioner.
Up to eight (four in RIM slots [2-5] and four in combo slots [6-9]) RIMs can be
hosted by the IHU
3. OIM- Optical Interface Modules; converts the RF to three optical link
Up to eight (four in OIM slots [10-13] and four in combo slots [6-9])
4. OIX- Optical Interface Expander; OIU to IHU interface Module.
5. HCM- Headend Control Module; overall system management module
6. ACM Auxiliary Control Module; provides interfaces for management of IHU
modules via HCM; installed in IHUs’ in configurations with more than one
headend unit (i.e. HEU/IHU)
7. PSM- Power Supply Module; AC or DC power supply
