SIST ETS 300 263/A1 E1:2003 is the Slovenian adoption of ETS 300 263 Amendment 1 for the Integrated Services Digital Network (ISDN) Telephony 7 kHz teleservice service description. Published by SIST, it updates the earlier service description by replacing references to ETS 300 281 with I-ETS 300 245-5 after ETS 300 281 was withdrawn. For engineers, terminal suppliers and telecom documentation teams, it is a reference update that keeps ISDN 7 kHz telephony descriptions aligned with the current terminal standard.

What does SIST ETS 300 263/A1 E1:2003 specify?

SIST ETS 300 263/A1 E1:2003 specifies a targeted amendment to the ISDN Telephony 7 kHz teleservice service description. It keeps the subject of the original standard, but changes the cross-references that support mode handling, signalling and bibliography.

The amendment is organized around a few precise edits:

Location	What it covers
Clause 2	Replacement of the normative reference to the terminal standard
Subclause 6.2.4	Update to the communication-mode reference
Clause 8	Update to the reference used before supplementary services interrupt in-band signalling
Table 3	Update to the signalling-related reference list
Annex A	Deletion of the bibliographic reference to ETS 300 281

In practice, this means the document is for people maintaining or implementing the service description, not for redefining the teleservice itself.

What are the key requirements of SIST ETS 300 263/A1 E1:2003?

This amendment’s main requirement is to use I-ETS 300 245-5 wherever ETS 300 281 was previously cited. That matters because the service description now points to the correct terminal standard after withdrawal of the old one.

• Clause 2 replaces normative reference [13] with prI-ETS 300 245-5, titled for wideband 7 kHz handset telephony. In practice, anyone checking the reference list should use the newer terminal standard when interpreting the service description.
• Subclause 6.2.4 says that, depending on terminal capabilities, it shall be possible to change between communication modes according to I-ETS 300 245-5. This matters for terminal behaviour because mode changes must follow the updated handset telephony rules.
• Clause 8 requires in-band communication to revert to mode 0 before invoking supplementary services that interrupt in-band signalling, such as call hold, using I-ETS 300 245-5 as the reference. In practice, implementers need to verify the handover from speech or signalling communication to the baseline mode before the interruption.
• Table 3 replaces ETS 300 281 with I-ETS 300 245-5 in the signalling reference set. This matters for compliance documentation because the signalling framework must cite the current standard.
• Annex A removes the bibliographic reference to ETS 300 281. In practice, that keeps the bibliography consistent with the withdrawn document status.
• The foreword states that the amendment was produced by ETSI Technical Committee Network Aspects and that the replacement was made because ETS 300 281 was withdrawn. This gives the reason for the change, which is useful when tracing document history.

What changed in SIST ETS 300 263/A1 E1:2003 from the previous edition?

SIST ETS 300 263/A1 E1:2003 is Amendment 1 to the first edition of ETS 300 263 (1994). The stated change is straightforward: all occurrences of ETS 300 281 are replaced with I-ETS 300 245-5.

The amendment updates:

• the normative reference in clause 2,
• the mode-change text in subclause 6.2.4,
• the supplementary-services text in clause 8,
• the signalling list in Table 3,
• and the bibliography in Annex A.

Which standards are used with SIST ETS 300 263/A1 E1:2003?

• I-ETS 300 245-5 - the replacement reference used for wideband 7 kHz handset telephony and communication-mode behaviour.
• ETS 300 011, ETS 300 012, ETS 300 125, ETS 300 102, ETS 300 267 - listed in Table 3 as signalling-related references that support the service description’s signalling context.

What does the SIST ETS 300 263/A1 E1:2003 document contain?

The document contains a short foreword, transposition dates, a set of amendment instructions, and a history note. The amendment instructions point to exact places in the base standard where references are changed.

It also includes the edited text locations for clause 2, subclause 6.2.4, clause 8, Table 3 and Annex A. These edits are the practical core of the amendment.

For readers maintaining compliance files or technical specifications, the document functions as a controlled reference update. For implementers, it tells you which standard to follow when the service description refers to telephony terminal behaviour and signalling interruptions.
