7. If using a POTS phone with the Express 4110/4120, connect the POTS
telephone to the POTS port.
If the SPID(s) does not work or is unknown, try activating the ExpertISDN™ feature. First
enter the area code and local directory number(s); then press the Enter key over the ExpertISDN
activator.
CONNECTING TO AN INTERNET SERVICE PROVIDER
Internet Access using Network Address Translation (NAT)
1. Connect the Express 4110/4120 to the 10BaseT LAN.
2. Go to the Configuration/Connection List menu, and then press the
right arrow key to place the cursor on the Num column.
3. Type I to insert a new Connection List entry.
4. Using the arrow keys, move the cursor over the Num column for the
inserted entry. Press Enter to place the subentries into the right pane.
5. Set the Description to an identifiable name (i.e., ISP).
6. Go into the Authentication field and select PAP or CHAP for the Tx
Method
.
7. Enter your user name and password (provided by your ISP) into the
Tx Username
and Tx Password fields.
8. Move the cursor to the left pane and highlight the IP parameters.
9. Set the NAT item to ON. This is a very important step. The Express
4110/4120 will need to translate the “fake” IP address(es) on the PC(s)
to the “real” address provided dynamically by the ISP. See “IP/NAT”
on page 3-18 for more details.
10. If you want the 4110 to automatically connect to your ISP whenever
you try to access the Internet, go into the Route field and enter the IP
address and mask of the ISP router. If the address of the ISP router is
not known, enter a bogus address such as 172.16.1.1 with mask
255.255.0.0 and the 4110 will dynamically resolve the correct address
of the ISP router. Otherwise, all other IP parameters should be left at
their default settings.
11. Navigate to the Dial Out parameters. Enter the telephone number
provided by the ISP into Number 1. If the ISP is providing you a mul-
tilink PPP (2 B channel), enter Number 2 if it is provided. Set Initial
Channels
to 2 if you desire to connect both B channels on each initial
call.
