ISDN dialing parameters
This section of the web interface appears when the router is fitted with an optional internal ISDN
MODEM card. When first powered up, navigating to the
Configuration > Network > Interfaces >
ISDN
page will show 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 > ISDN
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.
This ISDN interface is using PPP n
This message simply states which PPP instance has been assigned to the interface.
Description
A memorable name for the interface. This may be useful when referring to the interface,
rather than having to remember the name and the function of the interface.
Dial out using numbers
The telephone numbers that should be used, in sequence, to make an outgoing connection.
Prefix n to the dial out number
The dialing prefix to use, if needed. This may be necessary when using a PABX.
Username
The username that should be used when using the PPP instance to connect to the remote
peer. This will normally be provided by an ISP for use with a dial-in Internet access service.
Password
The password to use for authenticating the remote peer and is used in conjunction with the
above username.
Confirm password
Type the password into this text box to enable the router to confirm that the password has
been entered identically in both boxes.
Allow the remote device to assign a local IP address to this router
When this radio button is selected, the remote peer will assign this PPP interface an IP
address.
Try to negotiate a.b.c.d as the local IP address for this router
If it would be useful, but not essential, to have a predefined IP address for the interface, the
second radio button should be selected and the desired IP address entered into the text box
to the right.
Use a.b.c.d as the local IP address for this router
If it is essential that the PPP interface has a specific IP address, this radio button should be
selected and the IP address entered into the text box.
