modem speed. 300bps (Bell 103 & ITU-T V.21 protocol) 2400 to 12,000bps (ITU-T V.32, V.32bis and V.34 protocols) Connections limited to this range indicates severe channel impairment. Usually noise and bandwidth restrictions cause connect speeds this low. Long cable runs of over 5 or 6 miles can cause it, as can very old analog carrier systems. 14.4Kbps (ITU-T V.32bis and V.34 protocols) This is the minimum speed that a V.34 modem
