Planning for CSX400 ISDN Configuration
30 CSX400 and CSX400-DC User’s Guide
Collect Network Information
Before you begin, you need to obtain information about the network to which you are adding the
CSX400. Some of the information is obtained from your central site or remote site network
administrator. Other information is obtained from your ISDN service provider.
You must define the name and security password of the CSX400, ISDN line information and the
Ethernet LAN IP and/or IPX address. You need to identify all of the remote routers and their
routing and bridging capability, ISDN phone numbers, addressing and security information. You
also need to decide whether you will use Internet Firewall Filtering if you are using IP routing. The
following sections contain diagrams and tables to help you gather and organize the information.
Names and Passwords
You must choose a name for the CSX400 and the authentication password, both of which are used
by a remote site to authenticate the target router. For each remote router, you must have the router
name and its authentication password which is used by the CSX400 to authenticate the remote
router. The name and password are used in both PAP and CHAP authentication. Figure 3 shows
how this information is used.
