    Further Details

    Keep leased-line failures from costing you time and money. The instant the RS-232 Fallback Switch detects a lapse in the primary line, it switches your system to a backup line. As soon as signal is restored, it switches back to the primary line. The switch can support data rates as high as your RS-232 line can carry.
