A leased line with no battery or signaling will not work with the Router’s V.32 bis or V.34 modems.
Sometimes called a “dry pair,” this type of line is often provisioned for a local connection. If this is
the only type of line offered, you can augment it with a separate “ringdown box,” in order to turn it
into an equivalent of a ringdown line (described previously).
4. 4-wire leased line
A 4-wire leased line will not work with the Router’s V.32 bis or V.34 modems.
Connecting to an Internet Service Provider (ISP)?
Before configuring your Router to connect to an Internet Service Provider (ISP), obtain the following
information from your Internet Service Provider.
Intended IP addresses at your site.
• Your Router’s IP address
• The set of IP addresses available for hosts on your LAN
• Subnet masks used
• The IP addresses of any domain name servers
The system at the ISP that the Router will connect to, using the PPP protocol.
• The type of system to which your Router will connect to
• Custom dialing script, if required
• The IP address of that system
• Username and password
• If PAP or CHAP is used, the name and password required for authentication
At the end is a sample dialer script. The following sections provide more detail.
Intended IP addresses at your site
• Your Router’s IP address
You do not need a separate IP address for the modem interface in your Router. The same IP address
assigned to your Router is the one used by your modem interface.
• The set of IP addresses available for hosts on your LAN
Depending on your LAN requirements, you may be assigned a whole class C address (e.g.
204.125.5.xxx), or a smaller set of IP addresses (e.g. from 204.125.5.17 to 204.125.5.23).
• Subnet masks used
You must specify the subnet mask to be used.
• The IP addresses of any domain name servers
You can have domain name servers at the ISP site or on your LAN.
