Summary

This Recommendation gives a framework for dynamic routing interworking in circuit-switched PSTN, narrow-band ISDN, and broadband ISDN networks. It illustrates the functionality for setting up a call from an originating exchange in one network to a destination exchange in another network, using one or more dynamic routing methods in conjunction possibly with fixed routing. It describes:

a)��������� relevant dynamic routing functions for TDR, SDR, and EDR networks;

b)��������� information flows required for dynamic routing interworking between exchanges; and

c)��������� several examples of interworking between different dynamic routing methods.
