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 specifies the definition of Profile TD43211. The TD43211 profile is in the TC group which supports Transport protocol class 0.
Position of Profiles within the Taxonomy
The taxonomy of profiles is defined in ISO/IEC TR 10000-2. This part of ISO/IEC ISP 10609 defines the profile:
TD43211 Connection-
NOTE - At the date of publication, there is no difference from a terminal point of view between "permanent" and "semi-permanent" connections. However, ITU-T may define a procedure that would allow an ISDN terminal to have a semi-permanent connection set up in support of permanent Bchannel. At that time, amendments to this profile may be necessary. This profile uses the term "permanent".
This profile may be combined with any A-profile at the A/T boundary
Scenario
The reference End System is directly attached to the ISDN at an S/T reference point of a Basic or a Primary Rate Access.
This part of ISO/IEC ISP 10609 specifies the required functions from the supporting protocol
At layer 1, CCITT I.430 is used for ISDN basic access and CCITT I.431 is used for primary rate access. At layer 2, ISO 7776 provides the LAPB Data Link procedures for the B-channel. At layer 3, ISO/IEC 8208 packet layer protocol is used in DTE/DCE mode on the B-channel. The provisions of ISO/IEC 8878 apply with regard to the mapping of the CONS primitives and parameters to and from the elements of the ISO/IEC 8208 packet layer protocol.
Network Service connection establishment and release are single stage processes, involving the establishment or release of a virtual call. (But, the Data Link layer connection need to be established by user or PH.)
