Specify the DTMF tone duration.
Specify the interval of DTMF digit
Specify the limitation of Ring time for incoming call, when the ring is over the limit, system will drop the call. The default range is 10~600sec. Specify the duration (100~1000ms) of loop current drop, 0 for disable. This feature is used when the SP5008A (FXS) are connected with answering machines. When the remote site disconnects, the system will drop FXS port’s voltage to 0, and make the answering machines disconnect.
This option is used when a stand alone relay box containing a PSTN and FXS port is connected to the SP5008A’s FXS port. In this special application, if there is a network or registration failure, the system will drop the FXS port’s voltage to 0, when the relay box detects the status, it will switch the line to PSTN.
