6.5 Voice to Data Switch
Command line: ATA <CR> or ATX1D <CR>
If you are talking with a remote modem user through the telephone set and want to initiate data
communication with the remote modem, follow the procedures below:
1. You or the remote user issue an ATA command first to switch to data communication.
2.
When the person on the other end hears an answer tone from the phone, issues an ATX1D
command (X1 to disable the dial tone monitor) to instruct the modem to go off-hook and wait for a
carrier. If connection is successful, the CONNECT XXXX result code will be displayed on the
screen. Now you can hang up your phone and begin data communication with the remote modem.
