WAN Setup 7-13
For ISDN lines, there are many more protocols and operational modes. Please consult the
documentation of your TA. You may need additional commands in both “Dial” and “Init” strings.
7.11 DTR Signal
The majority of WAN devices default to hanging up the current call when the DTR (Data Terminal
Ready) signal is dropped by the DTE. When the “Drop DTR When Hang Up” check box is selected,
the Prestige uses this hardware signal to force the WAN device to hang up, in addition to issuing the
drop command “
ATH”
.
7.12 Response Strings
The response strings tell the Prestige the tags, or labels, immediately preceding the various call
parameters sent from the WAN device. The response strings have not been standardized; please
consult the documentation of your WAN device to find the correct tags.
