over a leased line, Motorola recommends the following configuration:

• Set the 3460 to V.34 Only modulation mode (AT*MM parameter)

• Set the 326X modulation mode to:

— V.34 Auto if it is set to Originate

— V.34 Only if it is set to Answer

• Set the maximum modem (DCE) rate (AT*MX parameter) to 31.2

on at least one modem.
