It was at this time that CCITT was renamed the Telecommunication Standardization Sector ( ITU-T ), as one of three Sectors of the Union alongside the Radiocommunication Sector ( ITU-R ) and the Telecommunication Development Sector ( ITU-D ).

Since 1975, CCS protocols have been developed by major telephone companies and the International Telecommunication Union Telecommunication Standardization Sector ( ITU-T ); in 1977 the ITU-T defined the first international CCS protocol as Signalling System No . 6 ( SS6 ).

In contrast to then-existing ITU Telecommunication Standardization Sector ( ITU-T ) V-series protocols, such as the common 2400 bit / s V . 22bis, the TrailBlazers'proprietary " Packetized Ensemble Protocol " ( PEP ) modulation employed a large number ( initially up to 512 ) of closely spaced carrier frequencies, each modulated at 6 baud, encoding 0, 2, 4 or 6 bits per interval.
