Chapter 4: Planning for HSIM-W6 ISDN Configuration

Collect Network Information

Before you begin, you need to obtain information about the network to which you are adding the HSIM-W6. 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 HSIM-W6, 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 HSIM-W6 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 HSIM-W6 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.
