8.16.2 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 ZyWALL uses this hardware signal to force the WAN device to hang up,
in addition to issuing the drop command ATH.
8.16.3 Response Strings
The response strings tell the ZyWALL 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.
