Summary

This Recommendation specifies the characteristics and applications of an isolation function for use with phoneline networking transceiver devices in accordance with ITU-T Recs G.989.1 and G.989.2.

The Recommendation describes how the isolation function may apply in the system reference model for in-premises phoneline networking transceivers (PNT), provides examples of usage of the isolation function, and specifies the characteristics of an isolation function which performs spectral isolation by means of a filter.

Requirements for the implementation and deployment of G.989.3 devices are outside the scope of this Recommendation.
