Information Technology - International Standardized Profiles TB, TC, TD and TE - Connection-Mode Transport Service over Connection-Mode Network Service - Part 21: Subnetwork-Type Dependent Requirements for Network Layer and Data Link Layer for ISDN B-Channel X.25 DTE to DTE Operation
|Publication Date:||1 January 1999|
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 specifies the requirements for Network Layer and Data Link Layer that apply specifically to configurations involving access to an ISDN subnetwork for B-channel X.25 DTE to DTE operation (Semi-permanent or Circuit-mode service).
