(Combination of Q.6/16 and Q.7/16)

Background

During the 1997-2000 study period new Recommendations were developed and many existing Recommendations were modified. The need for the continued study of DTE-DCE interfaces and protocols to keep pace with changing modem and DTE technologies and applications remains of high importance.

Items for study

1) The definition of DTE-DCE interchange circuits including functional and electrical characteristics.

2) Protocols to be used by the DTE to transfer information over the DTE-DCE interface for the purposes of:

• dialling; and
• configuration and control of the local DCE by the DTE.

3) The extension of DTE-DCE protocols to the remote DCE (DTE), to be considered in conjunction with Question 14/16.

Specific tasks

The development of new DTE-DCE interface-related Recommendations as well as revising existing ones. Develop new control Recommendations as well as the update of Recommendations V.25, the V.25X-series and V.80.

Relationships

• ITU-T Study Group 7 on DTE-DCE interface issues.
• ISO/IEC JTC 1/SC 6 on DTE-DCE interface issues.
• Other questions of SG 16 on the Mediacom 2004 Project.
• ITU-T SG 8 on fax and audiographics conferencing.
• Other organizations using "AT" commands, e.g. ETSI.
