Configure PSTN interfaces
The the
Configuration > Network > Interfaces > PSTN
section of the web interface is displayed
when the router is fitted with an optional internal PSTN MODEM card. When first powered up,
navigating to the
Configuration > Network > Interfaces > PSTN
page shows a message
indicating that the MODEM card does not have a PPP instance associated with it. Follow the link
on the page and select an unassigned PPP interface to the MODEM. When the browser is
refreshed and the
Configuration > Network > Interfaces > PSTN
page redisplayed, it should
show the parameters described below, along with a message at the top of the page indicating
which PPP instance has been selected.
