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 “Drop DTR When Hang Up” is set to yes,
the Prestige will use this hardware signal to force the WAN device to hang up, in addition to
issuing the drop command (ATH).
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.
