Installation Options
Disable Data Metering Feature
This option is set, by default, for Yes . This requires the 8400B Plus Data Module
to adjust its transfer speed to match the transfer speed of the remote system.
The
CONNECT xxxx message is displayed to indicate the transfer speed
selected when the connection is made.
Changing this option to
No allows the user to set up a call to a remote end that
is running at a slower speed than the local data module, without having to lower
the speed of the terminal. The
CONNECT xxxx message will always indicate
the speed of the local data transfer. The 8400B Plus Data Module performs the
speed conversion and uses the Clear to Send (CTS) lead to flow-control the
user’s terminal if it is sending too much data too fast.
NOTE:
If you are using a PC with a communications package, or a dedicated
terminal that does not support CTS control, you cannot make file transfers
with the data metering feature enabled.
NOTE:
A change in the setting of this option becomes effective immediately when
the 8400B Plus Data Module is in the idle mode or as soon as it is
returned to the idle mode. The 8400B Plus Data Module is in idle mode
any time that it is
not in test mode or connected to an active data call.
Immediate Speakerphone Activation
This option is set, by default, for Yes . This permits the speakerphone (if
available) to be activated before dialing, and allows the user to hear the
dial-tone and touch-tones when the
Telephone Provides Dialing option is set to
Yes . (See ‘‘Telephone Provides Dialing’’ on page 2-13.)
Setting this option to
No causes the speakerphone to be activated after dialing.
The user can still hear the far-end ringing and answering.
