This Recommendation describes methodologies and reference fixed system characteristics for implementation of the System Specific Methodology (SSM) of Appendix 5 of the Radio Regulations (RR), which allows a detailed assessment of the need to coordinate frequency assignments for non-geostationary (non-GSO) space stations (space-to-Earth) and receiving systems in the fixed service (FS). The Recommendation also describes a possible methodology for use in bilateral coordination of non-GSO mobile-satellite service (MSS) transmitting space stations with stations of the FS.

Levels of power flux-density (pfd) are presented as thresholds for coordination of frequency assignments for geostationary (GSO) space station transmitters in the mobile-satellite service (MSS) and receiving stations in the fixed service in frequency bands shared between these services in the 1-3 GHz frequency range. The Annexes address fixed system considerations that may facilitate coordination and summarize studies of frequency sharing between transmitting fixed stations and GSO space station receivers in the MSS.

Frequency bands have been allocated and identified for use by GSO and non-GSO FSS systems in bands shared on a primary basis with the FS. WRC-95/97 adopted a different set of provisions through No. 5.523A of the Radio Regulations (RR) to the non-GSO FSS utilizing the bands 18.8-19.3 GHz and 28.6-29.1 GHz from those provisions for non-GSO FSS utilizing bands outside these bands. This Report addresses only the 18.8-19.3 GHz band, which is referred to throughout as the 18/19 GHz band.

The purpose of this ITU-T Recommendation is to define the Generic Multimedia Conversational Service and to describe their general features, regardless of the network environment in which these services are provided. These services allow conversational communication between two users in two different locations. The Generic Multimedia Conversational Services are one of the generic service types identified in ITU-T Recommendation F.700, and their description follows the methodology described therein. The user requirements for the various applications supported by the service are translated into generic service specifications, independent of the constraints of specific implementations. Thus this ITU-T Recommendation sets out the requirements that will satisfy the users' needs and allow proper intercommunication on an international basis of services offered by different providers and of equipments £rom different manufacturers.
