ITU-T Study Groups (Study Period 2001 - 2004)
 General Areas of Study of the ITU-T Study Groups

The Study Groups drive their work primarily in the form of Study Questions. Each of these addresses technical studies in a particular area of telecommunication standardization.
Study Group 2
Operational aspects of service provision, networks and performance
Lead Study Group for service definition, numbering and routing.

Responsible for studies relating to:

- principles of service provision, definition and operational requirements of service emulation;
- numbering, naming, addressing requirements and resource assignment including criteria and procedures for reservation and assignment;
- routing and interworking requirements;
- human factors;
- operational aspects of networks and associated performance requirements including network traffic management, quality of service (traffic engineering, operational performance and service measurements);
- operational aspects of interworking between traditional telecommunication networks and evolving networks;
- evaluation of feedback from operators, manufacturing companies and users on different aspects of network operation.
Study Group 3
Tariff and accounting principles including related telecommunication economic and policy issues

Responsible for studies relating to tariff and accounting principles for international telecommunication services and study of related telecommunication economic and policy issues. To this end, Study Group 3 shall in particular foster collaboration among its Members with a view to the establishment of rates at levels as low as possible consistent with an efficient service and taking into account the necessity for maintaining independent financial administration of telecommunication on a sound basis.
Study Group 4
Telecommunication management, including TMN
Lead Study Group on TMN.

Responsible for studies regarding the management of telecommunication services, networks, and equipment using the telecommunication management network (TMN) framework. Additionally responsible for other telecommunication management studies relating to designations, transport-related operations procedures, and test and measurement techniques and instrumentation.
Study Group 5
Protection against electromagnetic environment effects

Responsible for studies relating to protection of telecommunication networks and equipment from interference and lightning.

Also responsible for studies related to electromagnetic compatibility (EMC), to safety and to health effects connected with electromagnetic fields produced by telecommunication installations and devices, including cellular phones.
Study Group 6
Outside plant

Responsible for studies relating to outside plant such as the construction, installation, jointing, terminating, protection from corrosion and others forms of damage from environment impact, except electromagnetic processes, of all types of cable for public telecommunications and associated structures.
Study Group 9
Integrated broadband cable networks and television and sound transmission
Lead Study Group on integrated broadband cable and television networks.

Responsible for studies relating to:

- Use of cable and hybrid networks, primarily designed for television and sound programme delivery to the home, as integrated broadband networks to also carry voice or other time critical services, video on demand, interactive services, etc.
- Use of telecommunication systems for contribution, primary distribution and secondary distribution of television, sound programmes and similar data services.
Study Group 11
Signalling requirements and protocols
Lead Study Group on intelligent networks.

Responsible for studies relating to signalling requirements and protocols for Internet Protocol (IP) related functions, some mobility related functions, multimedia functions and enhancements to existing Recommendations on access and internetwork signalling protocols of ATM, N-ISDN and PSTN.
Study Group 12
End-to-end transmission performance of networks and terminals
Lead Study Group on Quality of Service and performance.

Responsible for guidance on the end-to-end transmission performance of networks, terminals and their interactions, in relation to the perceived quality and acceptance by users of text, speech, and image applications. This work includes the related transmission implications of all networks (e.g., those based on PDH, SDH, ATM and IP) and all telecommunications terminals (e.g., handset, hands-free, headset, mobile, audiovisual, and interactive voice response).
Study Group 13
Multi-protocol and IP-based networks and their internetworking
Lead Study Group for IP related matters, B-ISDN, Global Information Infrastructure and satellite matters.

Responsible for studies relating to internetworking of heterogeneous networks encompassing multiple domains, multiple protocols and innovative technologies with a goal to deliver high-quality, reliable networking. Specific aspects are architecture, interworking and adaptation, end-to-end considerations, routing and requirements for transport.
Study Group 15
Optical and other transport networks
Lead Study Group on access network transport.
Lead Study Group on optical technology.

Study Group 15 is the focal point in ITU-T for studies on optical and other transport networks, systems and equipment. This encompasses the development of transmission layer related standards for the access, metropolitan and long haul sections of communication networks.
Study Group 16
Multimedia services, systems and terminals
Lead Study Group on multimedia services, systems and terminals.
Lead Study Group on e-business and e-commerce.

Responsible for studies relating to multimedia service definition and multimedia systems, including the associated terminals, modems, protocols and signal processing.
Study Group 17
Data Networks and Telecommunication Software
Lead Study Group on frame relay, communication system security, languages and description techniques.

Responsible for studies relating to data communication networks, for studies relating to the application of open system communications including networking, directory and security, and for technical languages, the method for their usage and other issues related to the software aspects of telecommunication systems.
Special Study Group on IMT-2000 and beyond
IMT-2000 and beyond
Lead Study Group on IMT 2000 and beyond and for mobility.

Responsible for studies relating to network aspects of International Mobile Telecommunications 2000 (IMT-2000) and beyond, including wireless Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia functions, internetworking, interoperability and enhancements to existing ITU-T Recommendations on IMT-2000.
