Chapter 3 - AT Commands

3.8 V.34 Commands

The following commands apply only in V.34 mode.

%Fn Echo Canceler Frequency Offset Compensation

n = 0 or 1

Default: %F0

The %F command enables and disables echo canceler frequency offset compensation

which, when enabled, can decrease modem performance.

%F0 disables echo canceler frequency offset compensation.

%F1 enables echo canceler frequency offset compensation.

&RAn Asymmetric Bit Rate

n = 0 or 1

Default: &RA0

The &RA command enables or disables asymmetric bit rate operation in V.34 mode. The

asymmetric bit rate feature lets the modem transmit at one rate while receiving at a different

rate.

&RA0 enables asymmetric bit rate operation.

&RA1 disables asymmetric bit rate operation.

#Vn V.32terbo Handshake

n = 0 or 1

Default: #V1

Some V.32/V.32bis modems have problems handshaking when the MT2834MR6 includes

V.32terbo mode (19,200 bps) in its handshake. The bits that are used in the rate sequence

for V.32terbo can cause handshake failure. Use the #V command to include or exclude

V.32terbo mode from the handshake.

#V0 includes V.32terbo mode in the handshake.

#V1 excludes V.32terbo mode from the handshake.
