Fallback

In adverse line conditions, the modem

 

falls back from its current operating speed

 

to the next reliable slower speed in 2400

 

bps decrements (V.34 mode). If conditions

 

improve, the modem falls forward to the

 

fastest reliable speed in 2400 bps

 

increments. In K56flex mode, modem falls

 

back and falls forward in increments of

 

2000 bps.
