Work on modification of call signalling protocols to support Emergency
Telecommunications Service (ETS) has been in progress for many years. More
recently this has been joined by work on Telecommunications for Disaster Relief
(TDR), and work on early warning systems has just started. Now this work is
starting to spread below the service control layer, and thus is affecting a
number of Questions. It will be useful to have a resource permanently in place
to coordinate this work so that the implementation of specific capabilities can
be defined in an integrated rather than piecemeal fashion. This Question
provides the required resource. Emergency Communication capabilities are
currently embedded in Recommendations that are the responsibility of other
Questions, so that this Question will not initially have responsibility for
Recommendations of its own. However, it will be responsible for ensuring the
maintenance of existing Emergency Communication capabilities in Recommendations

Q.2630.3, Q.2931, and Q-Series Supplement 53.
Study items to be considered include, but are not limited to:
- What is the content of the work program of the Study Group required to
standardize the Emergency Communication capabilities called for by the plans
set by the respective lead Study Groups?
- What signalling requirements must be defined in support of Emergency
- What Recommendations must be created in response to these requirements
because the work is not covered by other Questions in the Study Group;
- What changes should be proposed to the overall plans maintained by the
respective lead Study Groups, to provide for new capabilities, to provide
better realization of capabilities already being standardized, or to remove
Tasks include, but are not limited to:
- Analysis of Emergency Communication capabilities to which priority has
been assigned by their respective lead Study Groups to determine the
specific study tasks that must be added to the work plans of individual
Questions of the Study Group.
- Ensuring that the necessary communications take place at the technical
level between the Questions of the Study Group, so that their work of
realization of Emergency Communication capabilities is effective,
consistent, and complete.
- Similarly ensuring that the necessary communications take place at the
technical level between the Questions of the Study Group, Questions of other
Study Groups, and other groups defining standards relating to Emergency
Communication, as identified by the plans maintained by the respective lead
- Reviewing ETS and TDR capabilities already implemented in
Recommendations within the area of responsibility of the Study Group, to
ensure that they are still relevant and effective.
- Contributing to the development and maintenance of the plans which are
the responsibility of the respective lead Study Groups for Emergency
Communication, including the proposal of new content when this seems
- Creation of Supplements defining signalling requirements in support of
- Creation of new Recommendations dealing with Emergency Communication
when these fall outside the scope of other Questions of the Study Group.
The Question is responsible for maintenance of the ETS and TDR aspects of the
following Recommendations: Q.931, Q.761, Q.762, Q.763, Q.764, Q.1902.1,
Q.Q.1902.3, Q.1902.4, Q.1950, Q.2630.3, Q.2931, and Q-Series Supplement 53. The
work that the Question oversees operates within the framework defined by
Recommendation Y.1271 and draft new Recommendation ITU-T Rec. Y.NGN-ET-Tech.
All other Questions of the Study Group. Questions specifically relating to
ETS and TDR in other Study Groups.
- Lead Study Groups for ETS and TDR respectively.
- Lead Study Group(s) for any other aspect of Emergency Communication.
- Activities of IETF, IEEE, and regional standards bodies dealing with ETS
and TDR or capabilities required to implement them.
