ITU-T standards (or in ITU terminology Recommendations) are available direct from ITU.
PDF versions of most published  ITU-T standards are available as free downloads.

The Society has the right to distribute MSWord versions of the standards free to members (click here).

SDL Forum Society members can usually download the most up to date versions, and also can participate in the discussion on the evolution of ITU System Design Languages and download documents under discussion. See the members download area (username and password needed). In particular, the member versions of Z.100 for SDL-2000 and Z.120 for MSC-2000 contain hyperlinks and are available in MSWord format as well as PDF.

ITU-T standards are available in hard-copy format and (for most of them) on CD-ROM from the ITU. For more information, please contact Sales Service:
