CAN/CSA-ISO/IEC ISP 10609-37-99 (R2008)

This National Standard of Canada is equivalent to International Standard ISO/IEC ISP 10609-37:1995. 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 specifies the definition of Profile TC43212. The TC43212 profile is in the TC group which supports Transport protocol classes 0 and 2. 1.2 Position or 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: TC43212 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
