TCP (Transmission Control Protocol) have been errored in transit.TCM is specified by the ITU-T Recommendations for modems at speeds of 19.2 kbps and higher. ITU-T Recommendations for dial-up modems (and maximum speeds) specifying TCM currently include V.32 (9600 bps), V.32bis (14.4 kbps), V.32ter (19.2 kbps), V.34 (28.8 kbps), and V.34bis (33.6 kbps), aka V.34+.
