Modem 34336
Normally, as part of the V.32 handshake, the calling modem begins sending
a sequence to the answer modem while the answer modem is still sending
answer tone. In this case, there is no T1 timer. However, the V.32
recommendation allows for a T1 time of up to 3 seconds, meaning that the
answer modem may be set to wait (before falling back) for up to 3 seconds.

The B option is available for all modes. If the Modem makes a connection at
one of the V.32 rates (4800 to 14,400 bps) or V.22 bis rate (2400 bps), it can
request that the remote modem send a retrain sequence.

• ENABLE — The modem requests a retrain sequence.
• DISABLE — The modem will not request a retrain sequence.
The Answer/Originate Default option is available for Hayes and Leased
modes (and manual originate/answer dial operation). It sets the Modem to
default to either answer or originate status.
modes (and manual originate/answer dial operation). It sets the Modem to
default to either answer or originate status.
• ANSWER — Sets the Modem to answer mode.
• ORIGINATE — Sets the Modem is set to originate mode.
The Answer Tone option is available for Hayes, V.25 bis, and Dumb modes.
The answer-tone frequency is selectable only if the maximum data rate is set
to 1200 bps (via the SPEED LIMIT menu), in which case the answer tone can
be set to either 2225 or 2100 Hz. Otherwise, the answer tone frequency is
2100 Hz (the standard for V.32 operation). In general, this setting should
not be changed (even for fallback with Bell standard modems, which use a
2225-Hz answer tone).

The Front Panel Control option is available for all modes. It controls the use
of the front panel. If disabled, the front panel of the modem will not respond
to changes to the Setup menus. Front Panel Control is a security feature
helpful in situations where it is undesirable for the modem’s configuration
to be changed.

Two speaker options are available: Speaker Control and Speaker Volume.
The Speaker Control option is available for all modes.
• ON — Speaker is on during the full modem handshake process and while
the unit remains on-line.
• OFF — The speaker is off; the call cannot be audibly monitored.
• ON TILL CD — Speaker remains on until a carrier signal (CD)
is detected.
