Type the password assigned by your ISP.
Type your password again to make sure that you have entered is correctly.
Use the drop-down list box to select an authentication protocol for outgoing calls.
Options are:
CHAP/PAP - Your Prestige accepts either CHAP or PAP when requested by this
remote node.
CHAP - Your Prestige accepts CHAP only.
PAP - Your Prestige accept PAP only.
Type the first (primary) phone number from the ISP for this remote node. If the
primary phone number is busy or does not answer, your Prestige dials the secondary
phone number if available. Some areas require dialing the pound sign # before the
phone number for local calls. Include a # symbol at the beginning of the phone
numbers as required.
Use the drop-down list box to select the speed of the connection between the dial
backup port and the external device. Available speeds are: 9600, 19200, 38400,
57600, 115200 or 230400 bps.
Type the AT command string to initialize the WAN device. Consult the manual of your
WAN device connected to your dial backup port for specific AT commands.
Click the Edit button to display the Advanced Modem Setup screen and edit the
details of your dial backup setup.
This field sets this route's priority among the three routes the Prestige uses (normal,
traffic redirect and dial backup). Type a number (1 to 15) to set the priority of the dial
backup route for data transmission. The smaller the number, the higher the priority.
If the three routes have the same metrics, the priority of the routes is as follows:
WAN, Traffic Redirect, Dial Backup.
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network to a different IP address known within another
network.
SUA (Single User Account) is a subset of NAT that supports two types of mapping:
Many-to-One and Server. When you select this option the Prestige will use Address
Mapping Set 255 in the SMT (see the section on menu 15.1 for more information).
Select this check box to turn on RIP (Routing Information Protocol), which allows a
router to exchange routing information with other routers.
The RIP Version field controls the format and the broadcasting method of the RIP
packets that the Prestige sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably
adequate for most networks, unless you have an unusual network topology. Both
RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that
RIP-2B uses subnet broadcasting while RIP-2M uses multicasting. Multicasting can
reduce the load on non-router machines since they generally do not listen to the RIP
multicast address and so will not receive the RIP packets. However, if one router
uses multicasting, then all routers on your network must use multicasting, also.
