European digital cellular telecommunications system (Phase 2); Interworking between a Public Land Mobile Network (PLMN) and a Packet Switched Public Data Network/Integrated Services Digital Network (PSPDN/ISDN) for the support of packet switched data transmission services (GSM 09.06)

REASON 1: Many existing PH support only X.31 case B. For these PHs the case A/B conversion in the GSM HPLMN is necessary. CONSEQUENCES OF NON-ACCEPTANCE 1: This amendment is necessary to allow basic packet access to PH supporting only case B. For these PH exists agreement between the PLMN and the fixed network operators to signal the case B between PLMN and ISDN. If the amendment is not accepted then the interworking could be faulty and a large number of PHs could not work efficiently.  REASON 2: In the case of more than one subscribed basic packet moded service, it is necessary to select one of the corresponding user rates as the PH does not send an applicable user rate.  CONSEQUENCES OF NON-ACCEPTANCE 2: The correct access of basic packet mode in case of more than one subscribed basic packet service is not guaranteed.

Foreword

This Amendment to ETS 300 603 (1994) has been produced by the Special Mobile Group (SMG)

Technical Committee of the European Telecommunications Standards Institute (ETSI).

This Amendment to ETS 300 603 (1994) corresponds to the changes to GSM Technical Specification

(GSM-TS) 09.06 from version 4.4.1 to version 4.5.0, as approved by TC-SMG.
This Amendment modifies pages 9, 12, 15, and 17 of ETS 300 603 (1994).
Amendments
Page 9, Clause 3.
Replace the existing bullet definition:
- GSM packet mode services "Use of X.31 case A";
with the following:
- GSM packet mode services "Use of X.31 case A":

A circuit connection shall be used for accessing the packet service (according to ETS 300 099), with

the significant characteristics of the connection identified by the following setting of the respective

parameters of the BC-IE:
* information transfer capability = unrestricted digital information
* transfer mode = circuit mode.

The issue of "loop detection" is of no concern in the case of X.31 Case A (ETS 300 099) because

the PH inserts - irrespective of being accessed by a home or a foreign roaming subscriber - into the

"calling address" of an outgoing X.25 "call request" packet the address of the B-channel port.

Page 9, Clause 3.
Between the definition bullet points:
- GSM packet mode services "Use of X.31 case A"; and
- Packet mode services via PSTN (X.32).
Insert the following two new definitions bullet points:
- GSM packet mode services "Use of X.31 case B"

A packet connection shall be used for accessing the packet service (according to ETS 300 099),

with the significant characteristics of the connection identified by the f
