Distinctive Ring
The Industrial Modem is able to discriminate between three different types of rings. This is useful if you purchase
the dual line service. With dual line service, two phone numbers are shared for one telephone line. One number
can be used for Voice and the other number can be used for your Modem. To enable the modem to answer only
when your modem number is dialled, issue the command: AT-SDR=4 S0=2&W.
AT-SDR=n,x
where n=0 to 7, default=0,
x=0 Disable Distinctive Ring response suffix;
x=1 Enable Distinctive Ring response suffix (default)
