In the case that a 3GPP TS or 3GPP TR would become almost identical to a document from another standards organization, the TSG may decide to prepare a 3GPP TS or 3GPP TR defining only the differences, if any, between that document (commonly called
"endorsed document") and the 3GPP TS or 3GPP TR.
Such a 3GPP TS or 3GPP TR, commonly called
"endorsement", shall be drafted in accordance with the present document, with the exceptions defined below.
If the endorsed document is referred to without modifications, the title of the 3GPP TS or 3GPP TR should be as close as possible to the title of the endorsed document, but comply with the provisions of
Annex D.
EXAMPLE 1:
Endorsement of ITU-T Recommendation Q.1215 (1993): "Physical plane for intelligent network CS-1", gives the 3GPP TS the title:
Intelligent Network (IN);
Physical plane for intelligent network Capability Set 1 (CS1)
[ITU-T Recommendation Q.1215 (1993)]
If the endorsed document is referred to with textual (technical and/or editorial) modifications, the title of the 3GPP TS or 3GPP TR shall indicate that.
EXAMPLE 2:
Endorsement of ITU-T Recommendation G.957 (1993): "Optical interfaces for equipments and systems relating to the synchronous digital hierarchy", gives the 3GPP TS the title:
Transmission and Multiplexing (TM);
Optical interfaces for equipments and
systems relating to the Synchronous Digital Hierarchy (SDH)
[ITU-T Recommendation G.957 (1993), modified]
This element is mandatory and shall be entitled
"Endorsement notice".
If the endorsed document is referred to without modifications, the following text should be used:
"All elements of …. apply."
If the endorsed document is referred to with modifications, the following text should be used:
"The elements of …. apply , with the following modifications:"
The modifications shall be presented in an order following the sequence of clauses of the endorsed document. General modifications shall precede specific modifications.
-
The use of manual revision marks for the presentation of the modifications is recommended. Deleted text should be struckout; inserted text should be underlined. Neither deleted nor inserted text should be coloured.
Designation of the serial order of an annex shall be with two letters, the first letter always being Z (i.e. ZA, ZB, ZC, etc.), in order to avoid confusion with any annexes of the endorsed document.
