ITU-T X.322 PDF

Scope and field of application

The purpose of this Recommendation is to describe the general arrangements for the interworking between PSPDNs and CSPDNs for the provision of data transmission services (Note 1). These arrangements are applicable only to the interworking involving transmission capabilities, and not to interworking involving communication capabilities as described in Recommendation X.300.

Note 1 - These arrangements could also be used for the support of telematic services.

Note 2 - The typing of subnetworks in this Recommendation is based on the support for the OSI connectionmode network service and is therefore only valid in that context.

Other types of subnetworks supporting other services and applications are for further study.
