Some applications require that the router (only for the ISDN models) be remotely activated, or
be able to dial up to the ISP via the ISDN interface. Vigor routers provide this feature by
allowing user to make a phone call to the router and then ask it to dial up to the ISP.
Accordingly, a teleworker can access the remote network to retrieve resources. Of course, a
fixed IP address is required for WAN connection and some internal network resource has to be
exposed for remote users, such as FTP, WWW.

Dial Retry - It specifies the dial retry counts per triggered packet.
A triggered packet is the packet whose destination is outside the
local network. The default setting is no dial retry. If set to 5, for
each triggered packet, the router will dial 5 times until it is
connected to the ISP or remote access router.
Dial Delay Interval - It specifies the interval between dialup
retries. By default, the interval is 0 second.
Remote Activation – It can help users who would like to access
the server which is off the Internet in the head office. To remotely
make the server to be available on the Internet, i.e. make the
router in the head office activating its Internet access either by
dialing-up or starting broadband connection, users can make a
regular phone call (the number is set in the Remote Activation
field) to the router as signaling it for activation. The phone call
will be soon disconnected once the router is on line.
Note that Dialing to a Single ISP should be pre-configured
properly.
Link Type - Because ISDN has two B channels (64Kbps/per
channel), you can specify whether you would like to have single
B channel, two B channels or BOD (Bandwidth on Demand).
Four options are available: Link Disable, Dialup 64Kbps, Dialup
128Kbps, Dialup BOD.
