| speeds |
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 V.90/K56flex mode, modem falls back and |
| falls forward in increments of 2000 bps |
