Command:

*DT

Wait for Digit Time-Out Time

Values:

 

 

n = 0, 1, 2 or 3

Default:

 

 

0

Description:

 

This command is used to configure the time between each

 

 

 

digit the modem will wait. If the modem has not received the

 

 

 

proper number of digits when the timer expires, it will report

 

 

 

the digits it has received so far and move on to the answering

 

 

 

sequence described in the *DN command.

Command:

*DN

Number of DID Digits Expected

Values:

 

 

0-7

Default:

 

 

0

Description:

 

This command is used to configure the modem for the

 

 

 

expected number of digits from the central office (the central

 

 

 

office will send the last few digits of the called number). When

 

 

 

the proper number of digits are received, the modem will pass

 

 

 

the digit information to the host computer. After passing the

 

 

 

digits the modem will answer the incoming call if S0 is greater

 

 

 

than 0. Otherwise the modem will wait for the host computer to

 

 

 

issue an ATA command.

Command:

*DW

Busy-Out Timer at End of Call

Values:

 

 

0-255

Default:

 

 

0

Description:

 

This command defines the amount of time to busy out the

 

 

 

modem upon disconnecting from a DID call. The delay is ended

 

 

 

when the timer runs out or a *DS command is received.

 

*DW0 This command disables the delay. It ends the delay, but it also

 

 

 

places the DID line a busy-out state.

 

*DW255 This command will extend the delay indefinitely.

 

About the Busy-Out Features and Functions

 

A Direct Inward Dial (DID) line can be put in a “Busy Out” state by

 

reversing the battery polarity the modem supplies to the line. This will

 

cause a caller to receiver either a busy signal in a single line system or

 

roll over to the next line in a trunk system.

-

Modem is set to the factory default DID start format *DS0

 

-

Modem receives an incoming ring on the POTS line

 

-

Modem is given the dial command ATD

 

-

Modem is set with the *DW command to busy-out delay after

 

 

finishing a call
