About TTC


Becoming a TTC member gives a number of advantages. Among them are the chance to participate in the development of TTC standards, see your own ideas reflected in ITU-T standards, join various technical seminars and access TTC documents such as TTC standards, TTC survey reports, and the latest technical information. TTC membership is also useful for those seeking to build their human networks.
