326X Leased-Line Operation Note
For optimum performance between a 3460 and a 326X in V.34 mode
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.
