International has published the International Datel Handbook. In more than 80 pages the new guide details the terminology, call set-up procedures, data transmission speeds and BTI MD dialling codes for incoming and outgoing Datel calls to and from 77 countries.
The transport industry is the UK's biggest user of International Datel, which transfers data signals from computers over the public telephone network at a range of transmission speeds.
