CAN/CSA-ISO/IEC ISP 10609-20-99 (R2007)

The international community has decided to make this standard available only in the English language version. It has been adopted as a National Standard of Canada on this basis. This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10609-20:1995. 1 Scope 1.1 General ISO/IEC ISP 10609 is applicable to end systems concerned with operating in the Open Systems Interconnection (OSI) environment. It specifies a combination of OSI standards, which collectively provide the connection-mode Transport Service using the connection-mode Network Service. This part of ISO/IEC ISP 10609 provides an overview of the multi-part structure for the ISDN TA profiles (which provide the Connection-mode Transport Service (COTS) using the Connectionless-mode Network Service (CLNS)) and for the ISDn TC and TD profiles (which provide the Connection-mode Transport Service (COTS) using the Connection-mode Network Service (CONS)).
