Summary

The advantages of migrating voice from an enterprise T1/E1 network onto Frame Relay are described as the main business reason for implementing Voice over Frame Relay. The Frame Relay technology and traffic policing options appropriate for voice are described. The standards specific to voice are covered in detail including Service Level Measurement, Voice Sub-Frame Structure, and Frame Fragmentation. The advantages of different types of fragmentation in different parts of the network are identified. The principles discussed in the chapter are illustrated by a case example for an enterprise network.
