Information technology - International Standardized Profiles TB, TC, TD and Te - Connection-mode Transport Service over connection-mode Network Service - Part 47: Definition of profile TD43212
This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10609-47:1995. 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 defines the profile TD43212. The TD43212 profie
is the TD Group which supports Transport protocol class 0. 1.2 Position within the taxonomy The taxonomy of OSI profiles is defined in ISO/IEC TR 10000-2. This part of
ISO/IEC ISP 10609 defines the profile: TD43212 Connection-mode Transport Service over connection-mode Network Service
over ISDN - Packet mode service - B-channel permanent access - Virtual
Call (VC) without use of Q.931 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 B-channel. 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.
