Abstract
A data communication apparatus having a low transmission mode and a high transmission mode. The apparatus includes a switch selector switching the transmission mode between the high transmission mode and the low transmission mode based on a received switching signal. A mode detector detects whether the switch selector has switched the transmission mode to the low transmission mode. A timer starts to clock a time period after the switch selector has switched the transmission mode from the high transmission mode to the low transmission mode. A rate detector detects a data bit-rate in the high transmission mode. A calculator calculates a waiting period based on the detected bit-rate. A disconnect unit disconnects a telephone line if the clocked time period exceeds the waiting period.
