Introduction

This Recommendation deals with the following aspects of interworking between networks for transport of 64 kbit/s digital information:

- encoding law and conversion rule for interworking between networks using the different encoding laws based on Recommendations G.711, G.721 and G.722.;

- interworking hierarchy between networks which incorporate the different digital hierarchies based on Recommendation G.702;

- interworking arrangements between networks incorporating the different hierarchies and encoding laws; and,

- interconnection by plesiochronous operation between networks which each has an independent synchronization.

This Recommendation is applicable also to ISDNs for transport of B channels specified in Recommendation I.412.

Note - The future specifications on channels and their bit rates to support ISDN broadband services for customer-to-customer applications may require additional interworking arrangement specifications other than those specified below.
