Use 854-9924 if you have a V.32bis or lower modem. If all lines are busy, this pool hunts to the V.34 pool.

Use 853-9903 if you have a V.34 modem. If all lines are busy, you'll get a busy signal. Dial this number only if you have a V.34 modem.

When dialing the low-speed Vadics, use 2400 bps and disable all error correction and compression features of your modem.

When dialing the USRs, use any speed, enable hardware flow control, V.42 or MNP4 error correction, and V.42bis or MNP5 compression if your modem has them.
