scope:

Recommendation ITU-T J.1108 describes the transmission specification for a radio over IP (RoIP) transmission system in a hybrid fibre coaxial (HFC) based network. The architecture described in this Recommendation is defined according to [ITU-T J.1106]. The transmission specifications described in this Recommendation are defined as follows:

- Radio over IP terminal system.

- Radio over IP headend system.

The most important part of the RoIP transmission system is having the correct network timing synchronization between the RoIP headend and RoIP terminal. The transmission specifications described in this Recommendation are defined in the timing processing specification.
