DE22
=Auto
The modem uses the autobaud feature to determine the rate at which to operate. For details, see
Chapter 5. NOTE: The Autobaud feature is not supported in synchronous operating modes.
When configured for synchronous operation, if you select Auto, the DTE will be driven at the
previous DTE rate selected (the factory default is 9600 bps).
Data Form
Data Format
Lets you specify the data encoding format to be used during SDC connections. NOTE: This
option applies only to SDC data mode. It does not apply to synchronous ACUs (V.25bis or
LPDA2) while disconnected. In the online mode, LPDA2 commands must follow the format of
this option.
AT
*
DF0
=NRZ
The modem uses the NRZ data encoding format.
AT
*
DF1
=NRZI
The modem uses the NRZI data encoding format.
L to D
Leased to Dial
In an automatic restoral application, the originating modem uses the setting of this command as
a trigger for automatic restoral. You select a threshold for the number of retrains to occur over
a period of time. The originating modem initiates restoral if the number is exceeded.
AT
*
DI0
=Low/Fast
This is the most sensitive setting. It lets the modem initiate restoral when signal quality
deteriorates slightly. For V.34/V.32/V.32 Uncoded/V.32bis modulation modes, 3 retrains must
occur within 5 minutes before a dial restoral connection is established. For other modulation
modes, 6 retrains must occur within 5 minutes before a dial restoral connection is established.
AT
*
DI1
=Low/Slow
For V.34/V.32/V.32 Uncoded/V.32bis modulation modes, 6 retrains must occur within 10
minutes before a dial restoral connection is established. For all other modulation modes, 12
retrains must occur within 10 minutes before a dial restoral connection is established.
AT
*
DI2
=High/Fast
For V.34/V.32/V.32 Uncoded/V.32bis modulation modes, 5 retrains must occur within 5 minutes
before a dial restoral connection is established. For all other modulation modes, 10 retrains
must occur within 5 minutes before a dial restoral connection is established.
AT
*
DI3
=High/Slow
For V.34/V.32/V.32 Uncoded/V.32bis modulation modes, 10 retrains must occur within 10
minutes before a dial restoral connection is established. For all other modulation modes, 20
retrains must occur within 1 minute before a dial restoral connection is established.
RTS/CTS Delay
RTS/CTS Delay
Sets the minimum interval for the delay time between RTS and CTS. These settings apply only
when operating in the asynchronous Direct or synchronous data modes.
AT
*
DL0
RTS/CTS
Delay=0
There is no RTS/CTS delay.
AT
*
DL1
=15
15-ms delay before the modem sends CTS to the DTE after receiving RTS from the DTE.
