SIST-V ETSI/EG 201 849 V1.1.1:2003 is an ETSI Guide for Bearer Independent Call Control (BICC) operation with the ATM Adaptation Layer (AAL) type 2 signalling protocol, Capability Set 1 (CS1). It is a supplement to ITU-T Recommendation Q.1901 and TRQ.3010 (1999), modified for the BICC/AAL type 2 trunking context. Engineers working on switching and signalling systems can use it to see which reference texts and edits apply when implementing or reading the BICC material.

What does SIST-V ETSI/EG 201 849 V1.1.1:2003 specify?

SIST-V ETSI/EG 201 849 V1.1.1:2003 specifies how the BICC protocol is operated with the AAL type 2 signalling protocol for CS1, with the focus on mapping and reference substitutions needed for AAL type 2 trunking. The guide is organized as front matter, an endorsement notice, clause 2 on references, and a history section.

The main technical action in the document is not a full protocol rewrite. Instead, it endorses the ITU-T supplement and applies ETSI modifications to the references used throughout that text.

What are the key requirements of SIST-V ETSI/EG 201 849 V1.1.1:2003?

SIST-V ETSI/EG 201 849 V1.1.1:2003 says that all elements of the supplement to ITU-T Recommendation Q.1901 and TRQ.3010 (1999) apply, except for the listed modifications. In practice, this means implementers should read the ITU-T supplement together with the ETSI replacements named here.

Clause 2 rules how references are handled

SIST-V ETSI/EG 201 849 V1.1.1:2003 replaces clause 2 with a references clause that distinguishes between specific and non-specific references. A specific reference is fixed to the cited edition, while a non-specific reference follows the latest version. This matters when a system is being implemented or reviewed against a stable edition.

The document redirects the core BICC reference

SIST-V ETSI/EG 201 849 V1.1.1:2003 maps ITU-T Recommendation Q.1901 and ITU-T Recommendation Q.765.5 to ITU-T Recommendations as modified by ETSI EN 301 848-1. For a reader, this means the BICC signalling procedures to use are the ETSI-modified ones in EN 301 848-1.

It ties cause and location handling to ETSI documents

SIST-V ETSI/EG 201 849 V1.1.1:2003 replaces the ITU-T references for Q.763, Q.850, and Q.2610 with the ETSI-modified versions in EN 300 356-1, EN 300 485, and ETS 300 685. In practice, this affects how causes and locations are interpreted across ISUP, DSS1, and B-ISUP-related work.

The reference list defines the supporting technical framework

SIST-V ETSI/EG 201 849 V1.1.1:2003 includes four named supporting documents in clause 2. These documents provide the protocol specification, ISUP basic services, cause and location definitions, and B-ISUP cause and location usage needed to read the supplement consistently.

The guide is a modification notice, not a full protocol specification

SIST-V ETSI/EG 201 849 V1.1.1:2003 mainly tells the reader which text to follow and where ETSI changes apply. That is useful in design reviews, conformance work, and interoperability testing because it prevents mixing unmodified ITU-T wording with ETSI-modified references.

What terms does SIST-V ETSI/EG 201 849 V1.1.1:2003 define?

• Bearer Independent Call Control (BICC) - a call control protocol used here in the context of trunking and signalling operation.
• ATM Adaptation Layer (AAL) type 2 - the ATM adaptation layer referenced for signalling transport in this guide.
• Capability Set 1 (CS1) - the capability set named in the title and scope for the BICC operation covered here.
• ISDN User Part (ISUP) - the Signalling System No.7 part used for ISDN call control on the international interface.
• Digital Subscriber Signalling System No. one (DSS1) - the subscriber signalling system named in the supporting references for cause and location usage.
• B-ISUP - the Broadband ISDN User Part, used here in connection with cause and location handling.
• cause and location - the signalling information used in the referenced ISUP, DSS1, and B-ISUP documents.

Who uses SIST-V ETSI/EG 201 849 V1.1.1:2003?

SIST-V ETSI/EG 201 849 V1.1.1:2003 is used by telecommunications engineers, protocol implementers, network operators, and interoperability test teams working on switching and signalling systems. Quality managers and buyers can also use it to confirm which ETSI-modified references apply when BICC and AAL type 2 signalling are being specified or verified.

What changed in SIST-V ETSI/EG 201 849 V1.1.1:2003 from the previous edition?

SIST-V ETSI/EG 201 849 V1.1.1:2003 is identified as a modified supplement to ITU-T Recommendation Q.1901 and TRQ.3010 (1999). The stated modification is the replacement of clause 2 and the remapping of ITU-T references to the ETSI documents listed in clause 2.

Which standards are used with SIST-V ETSI/EG 201 849 V1.1.1:2003?

Reference	Contribution
ETSI EN 301 848-1	BICC signalling procedures in an ATM/IP/backbone network for CS1.
ETSI EN 300 356-1	ISUP basic services used for signalling system reference material.
ETSI EN 300 485	Definition and usage of cause and location in DSS1 and ISUP.
ETSI ETS 300 685	Cause and location usage in DSS2 and B-ISUP.

What does the SIST-V ETSI/EG 201 849 V1.1.1:2003 document contain?

SIST-V ETSI/EG 201 849 V1.1.1:2003 contains an intellectual property rights notice, a foreword, an endorsement notice, clause 2 on references, and a history section. The endorsement notice is the core technical part, because it states the modifications and gives the reference substitutions.

It also includes a short table that maps ITU-T recommendations in the supplement to the ETSI-modified documents to be used instead. That table is the practical reading aid for protocol work, because it shows which cited text controls each topic.
