SG16 GENERAL ISSUES

Study Group 16 held its fourth meeting at the University of Chile in Santiago, at the invitation of the Chilean Administration and the University.

SG16 has three Working Parties (WPs):

TD-42 (P LE N) TD-59 (P LE N) TD-48 (P LE N)

The activities of these Working Parties are reported below.

WORKSHOP ON MULTIMEDIA

A successful workshop on Multimedia Application and Network was held on May 17, 1999, the first day of SG16. The program is in Annex 3 to TD-70(P LE N). The presentations from the workshop are available at: ••http://www.ict.uchile.cl/itut.sg16/workshop.html http://www.itu.int/ITU-T/com16/santiago/index.html

LIAISO NS

TD-21(GE N) reports that Q4/4 has Determined (Approval 2/2000) the new X.700 series

technical corrigenda which provide guidance in the use of the new ASN.1 Recommendations. New ITU-T recommendations are no longr able to reference ASN.1 1990. The new reference is to X.680-1997 | ISO/IEC 8824-1:1998.

July 1999

TD-4(GE N) from SG11 provides the IMT-2000 preliminary consolidated work plan. Activities of SG2: TD-22(GE N) reports on the study of the expansion of E.164 (PSTN

numbering) from 3 to 4 digit country codes. Q1/2 anticipates exhaustion of 3 digit country codes

in 10-15 years. TD-24(GE N) provides a very preliminary draft of E.MM, Routing of multimedia connections when interworking with PSTN, ATM and IP networks. TD-25(GE N) notes the

establishment of a fraud prevention coordinator in SG2 and provides a list of six other organizations dealing with fraud prevention. WD2-20 is the Q13/Q14 response to this liaison. The response discusses the capabilities of H.235.

Activities of SG10 on Formal Description Languages: ••

Q2/10 has developed the ITU-T Object Definition Language Z.130 (TD-7(GE N).

SG10 is updating Recommendation Z.110-1996, Criteria for use of formal description

languages by the ITU-T (TD-8(GE N)). WD2-05 is Q13/16’s response to the Questionnaire for
