Planning for CSX400 ISDN Configuration
42 CSX400 and CSX400-DC User’s Guide
Sample Configuration
A sample configuration of a hypothetical network is provided in this section. Figure 10 depicts a
small office (FP2) accessing a central site (FP3) via an ISDN link. The small office also has access
to Internet through an Internet Service Provider (ISP).
The small office and central site have IP routing with a Class B addressing scheme and IPX
routing. Bandwidth-on-demand is configured for accessing central site FP3. A maximum of one
line is configured for calling the ISP (though two different phone numbers are defined for use).
Table 7 provides sample system settings, Table 8 provides sample settings for the remote router at
the FP3 site, Table 9 provides sample settings for the remote router at the ISP site and Table 10
provides sample bridging and routing settings.
