Normative references
References may be made to:
a)  specific versions of publications (identified by date of publication, edition number, version number, etc.), in
which case, subsequent revisions to the referenced document do not apply; or
b)  all versions up to and including the identified version (identified by "up to and including" before the version
identity); or
c)  all versions subsequent to and including the identified version (identified by "onwards" following the version
identity); or
d)  publications without mention of a specific version, in which case the latest version applies.
A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the same
number.

Temporary Annex A (normative):
Modifications to ITU-T Recommendation Q.765
This annex contains the proposed changes to the text of the ITU-T Recommendation Q.765 as agreed by TC SPS in the
meeting which addressed the national comments received following PE9748. The complete text of this annex will be
contributed to the ITU-T resolution 1 procedure for approval of Q.765. Once this procedure is finished, it is intended
that the annex be removed from this EN.
Since it is possible that some of the modifications below will not be included in Q.765 those that will not create any
compatibility problems in the case of mismatch between Q.765 and the present docuement are to become a part of the
main body of this EN. The modifications that do not become part of Q.765 and may result in an incompatibility when a
Q.765 based service and an EN 301 069-1 based service interwork will be removed from this EN. Each of the proposals
below is, therefore, marked appropriately in one of the following two ways:
- if the item is to be removed from the EN "remove"
- if the item is to be included in the EN "keep"
Clause 4, Abbreviations keep
Modify in the following way:
ACM                Address Complete Message
APM-user Application Transport Mechanism User Application
CPG                 Call Progress Message
IAM                 Initial Address Message
PRI                 Pre-Release Information Message
Subclause 7.2.1, Introduction keep
Add the following note just before the third bullet point:
NOTE:   In the case that no such acknowledgement is received by the PIN before reception of either:
an ACM indicating "subscriber free", or
a CPG indicating "alerting", or
an ANM or CON
with no APP (for the appropriate context) then if the application association for the call was essential, the
call shall be release and the maintenance function shall be notified.
Subclause 8.3, Information flows related to messages received by
keep
the node
Modify the 2nd sentence of the 2nd paragraph as follows:
For received messages, the mapping of APM_U_Data, APM_Data and APM_Transfer (tables 4, 5 and 6) primitives is
the reverse to that described in the tables for outgoing messages sent by the node in subclause 6.28.2.
ETSI
6 EN 301 069-1 V1.2.2 (1998-07)
Subclause 9.1, Table 14/Q.765 - Primitives between ISUP ASE and
SACF keep
Replace note of table 14 by:
NOTE:   Primitive flow from SACF to ISUP ASE - ‹
Primitive flow from ISUP ASE to SACF - fi
Subclause 10.2.1, Normal Procedures - Sending keep
Replace the sentence "How this is determined is implementation specific" by:
APM segmentation procedures shall only apply if it is not possible to transfer all parameters in the IAM, ACM, CPG,
CON, ANM or PRI message and SGM, if simple segmentation procedures are used, because the 272 octet MTP limit
would be exceeded.
Subclause 10.2.4, Segmentation keep
Modify the 2nd paragraph as follows:
The initial segment for each context must be transported in the first message and this initial segment size may be of zero
lengt
