Configure DialServ interfaces
The Dialserv option module mimics a telephone exchange in that it supplies the required voltages
on the line, generates a RING signal and has off-hook detection circuitry. You can use Dialserv to
provide similar functionality to dialing into an ISP using an analogue modem. The card also
contains an analogue modem to handle data on the line.
Use PPP/Protocol Switch
These radio buttons select whether the DialServ card uses a PPP instance or the protocol switch
functionality to control traffic on the interface. If PPP is selected, the web page expands to
display the standard PPP configuration settings. If Protocol Switch is selected, only the four
settings described immediately below are visible.
