Executive summary of the meeting of Study Group 5
(Geneva, 12-16 October 2009)

1. Statistics

Participants: 101 from 27 countries
Contributions: 37
TDs (not counted the revisions): 117
Outgoing Liaison statements: 9


2. Results related to Recommendations and other publications

2.1 Recommendations

SG5 consented on
  • new Recommendation L.1000 (L.adaptor): “Universal power adapter and charger solution for mobile terminals and other ICT devices” , this is the first recommendation in the "ICTs and Climate change" series
  • revised Recommendation K.56 "Protection of radio base stations against lightning discharges"
  • revised Recommendation L.24 "Classification of outside plant waste" - Recommendation coming from the former SG6.

2.2 Other publications

SG5 agreed on
  • the amendment to the Handbook on Earthing & Bonding. The modifications did not justify the republication of the Handbook, this will be done when more revisions are proposed.
  • the revision of the very old (1974) Handbook on the preservation of wooden poles carrying overhead telecommunication lines, also coming from the former SG6
  • the publication of an Implementer’s guide to Recommendation K.44 "Resistibility tests for telecommunication equipment exposed to overvoltages and overcurrents - Basic Recommendation".
3. Transfer of Recommendations and Handbooks from SG15

SG 5 accepted from SG 15 the following Recommendations and Handbooks (originally under responsibility of SG6) as they fall now under the scope of SG 5:

Number Title SG5 Qs
L.7 Application of joint cathodic protection 10/5
L.8 Corrosion caused by alternating current 10/5
L.21 Fire detection and alarm systems, detector and sounder devices 21/5
L.22 Fire protection 21/5
L.23 Fire extinction - Classification and location of fire extinguishing installations and equipment on premises 21/5
L.32 Protection devices for through-cable penetrations of fire-sector partitions 21/5
L.33 Periodic control of fire extinction devices in telecommunication buildings 21/5


Number Title SG5 Qs

1978 Jointing of Plastic-Sheathed Cables 10/5
1982 Jointing of Telecommunication Cable Conductors 10/5
1992 Outside Plant Technologies for Public Networks 10/5
2001 Protection of Telecommunication Buildings from Fire 21/5


4. Technical session

As usual, if the SG5 meeting is not combined with a workshop, we organize a technical session. This is an internal tutorial session (nearly 2 hours) on dedicated matters. This time the subject was: ICT & CC, to present the main subjects studied in the new WP3/5. The presentations were based on the deliverables of the previous FG on Climate change, as these documents form the basis of the work of WP3/5.

The Technical session was very well attended.

5. Home Networks Special Group

At the November 2008 SG5 meeting it was agreed, and reported in SG 5 R-01, that a special group would be set up to study some issues regarding damage to equipment in the home environment. At the May 2009 SG5 meeting it was agreed that Questions 4, 5, 6, 8, 10 and 13 need to be involved and a web page has been set up, see HNSG. At the October 2009 SG5 meeting it was agreed to have a new Recommendation to provide all requirements to minimise upset and damage to home networks. These requirements include: Resistibility, Safety, Earthing, Risk Assessment, Installation of Overvoltage Protection, Wiring Installation, Ring Earth and Special requirements.

6. Editing Group

In order to assure the high quality level of SG5 Recommendations, an Editing group was established at the beginning of the current study period. With the change of the mandate and the enlargement of the Study Group, it is necessary to have members who are experts in the new CC subject. Two new members, (Dave Faulkner (UK) and Franz Zichy (US)) will complete the Editing Group. The complete list of SG5 editorial team is:

Coordinator: Michael Maytum
Members: Darren Carpenter
Phil Day
Dave Faulkner
Mitsuo Hattori
György Varju
Ahmed Zeddam
Franz Zichy


7. Rapporteurs/Liaison Rapporteurs

A new Rapporteur was nominated for Q12/5 (as the original Rapporteur will continue with new Question 17/5): Mr. Xing Hai Zhang (Huawei, China). Mr Didier Marquet (France Telecom Orange) was confirmed as Associate Rapporteur for Q19/5.

In order to reinforce the liaison with IEC TC 108, a Liaison Rapporteur was nominated: Mr. Phil Havens (Littelfuse Inc.).

8. SG5 Regional Groups

8.1 Regional group for Africa Region

This group was established during the previous meeting of SG5. The web page was created and it was decided that the first meeting of this Regional Group will be held in June 2010 in Kenya.

A Questionnaire was submitted for this meeting in order to establish an overview of the practices implemented in the African countries and the standards applied to ensure that telecommunication installations comply with human exposure limits, and to evaluate African countries' knowledge of Study Group 5 standards on the subject. Unfortunately this time only very few representatives from African countries participated in the SG5 meeting, it was not possible to organize an ad-hoc regional group meeting to study this questionnaire. It was decided to post it on the website.

8.2 Regional group for Arab Region

A document was submitted to SG5 with the proposal to create a new SG5 Regional group for the Arab Region. This proposal was accepted by SG5.

The objectives of this group are as follows:
  • Increase the participation of Arab States in the work of SG5, with a view of ensuring that their specific regional needs and concerns are better taken into account;
  • Disseminate relevant information provided by SG5 on Environment and Climate Change, human exposure to electromagnetic fields, conformance and interoperability testing and other activities of SG5;
  • Write proposals to SG5;
  • Strengthen standard-making capabilities of the Arab States in accordance with Resolution 44 (Rev. Johannesburg, 2008) in particular with the four Programmes of the action of this Resolution (Programme 1, Programme 2, Programme 3 and Programme 4).
The chairman of this group was not yet nominated.

8.3 Regional group for Americas Region

A proposal was submitted to SG5 to create a new SG5 Regional group for the Americas Region. After discussion it was agreed that this group will be created during the next meeting of SG5 to be held in Argentina.

9. JCA on ICT & CC

The first meeting of JCA on ICT&CC was held on 14 October 2009 under the Chairmanship of Mr. Ahmed Zeddam (Convener) and Mr. Dave Faulkner (Co-convener). The meeting was face to face but some delegates participated remotely. (GoTo meeting was organized.) The report of the meeting (contained in TD337) will be posted on the web page of the JCA.

10. Future meeting

10.1 Interim meeting of WP3/5 and JCA ICT&CC

It was agreed that Working Party 3/5 – in order to take advantages of the presence of experts of different Study Groups – will have an interim meeting from 19 – 22 January 2010, during the meeting of NGN-GSI (Next Generation Networks Global Standards Initiative). The JCA on ICT&CC will meet on 21 January afternoon.

10.2 Next meeting of Study Group 5

The next meeting of Study Group 5 will be held from 12 – 16 April 2010 in Buenos Aires (Argentina). It is planned to have a tutorial session during this meeting (the subject will be defined ASAP)

However during the meeting there was a proposal to organize a workshop on EMFs jointly with the SG5 meeting. The organizers will look at the possibilities to extend the duration by one day. SG5 members will be informed in due time by the Collective letter announcing the meeting.
