          ITU-T SG 15 – OPTICAL AND OTHER TRANSPORT NETWORKS
                     REPORT TO UK ITU-T CO-ORDINATION


1.       General

The forth meeting of Study Group 15 in the 2001 - 2004 study period took place in
Geneva from the 20th – 31st January 2003 under the chairmanship of Mr. P. Wery
(Nortel Networks, Canada). It was attended by 288 delegates (16 from the UK)
representing 24 Administrations, 17 Recognised Operating Agencies, 61 Scientific
and Industrial Organisations, 6 Associates and 1 International Organisation.
The meeting considered 22 „white‟ contributions and 254 delayed contributions (98
addressed to Q.4/15). This was a record number of delayed contributions for the
current study period.

2.       Results

        SG 15 gave consent to submit 20 draft revised/new Recommendations,
         4 Corrigenda and 13 Amendments to Last Call under the Recommendation
         A.8 procedure
        SG 15 agreed the texts of 1 Appendix and 4 Implementors‟ Guides.

Details are given in Annex 1.

3.       Items of particular interest to the UK

G.989.3

G.989.3 “Phone-line Networking Transceivers - Isolation Function” was completed
and gained consent in line with UK proposals.

G.7712/.1703

The UK proposal for an Inter-working function (Auto-tunnelling) was included in the
revision of G.7712/.1703 “Architecture and Specification of Data Communication
Network” given consent by SG 15.

G.7713.1, .2 & .3

G.7713.1, .2 & .3, “Distributed Call and Connection Management (DCM) based on
PNNI”, “Distributed Call and Connection Management Signalling mechanism using
GMPLS RSVP-TE” & “Distributed Call and Connection Management Signalling
mechanisms using GMPLS CR-LDP” were consented „as a set‟ as proposed by the
UK.

GFP

The UK position against further development of GFP to provide additional layer
networks was presented and discussed. There was support from several carriers
who stated that they did not wish to develop the OAM and OSS support for a GFP
based alternative to existing technologies such as ATM and MPLS.

4.       Future Meetings
The next plenary meeting of Study Group 15 is scheduled to take place in Geneva
from the 21st – 31st October 2003. The plenary gave its approval for 14 interim
Rapporteurs‟ meetings, details of which are given in Annex 2.
