Description

 

 

 

AT*DE23

=48.0

The DTE port is configured for 48,000 bps. Available with SDC feature only.

AT*DE24

=56.0

The DTE port is configured for 56,000 bps. Available with SDC feature only.

AT*DE16

=57.6

The DTE port is configured for 57,600 bps.

AT*DE17

=64.0

The DTE port is configured for 64,000 bps. Available with SDC feature only.

AT*DE18

=72.0

The DTE port is configured for 72,000 bps. Available with SDC feature only.

AT*DE19

=76.8

The DTE port is configured for 76,800 bps.

AT*DE20

=96.0

The DTE port is configured for 96,000 bps.

AT*DE21

=115.2

The DTE port is configured for 115,200 bps.

AT*DE28

=128.0

The DTE port is configured for 128,000 bps.

AT*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

There is no RTS/CTS delay.

 

Delay=0

 

AT*DL1

=15

15-ms delay before the modem sends CTS to the DTE after receiving RTS from the DTE.
