DI-304/DI-304M ISDN Remote Router
◊Link Disable – Disables the ISDN
◊Dialup 128Kbps – Uses both ISDN B channels for Internet access.
◊Dialup BOD – BOD stands for
Setup.
♦PPP Authentication – Two types of authentication
◊PAP Only - Set the PPP session to use the PAP protocol to negotiate the username and password with the ISP.
◊PAP or CHAP - Sets the PPP session to use the PAP or CHAP protocols to negotiate the username and password with the ISP.
IP Address Assignment Method (ICPC)
♦Fixed IP and Fixed IP Address – In most environments you should not change the default settings as most ISPs provide a dynamic IP address for the router when it connects to the ISP. If your ISP provides a fixed IP address, check Yes and enter the assigned IP address in the Fixed IP Address field.
DSL/Cable Modem Internet Access
Before you connect a broadband access device, e.g. a DSL/Cable modem, to the router, you need to know what kind of Internet access is provided by your ISP.
The following paragraphs deal with three widely used broadband access services. These are PPPoE Client, PPTP Client, and Static IP for DSL/Cable Modem. In most cases, you will get a DSL/Cable modem from the broadband access service provider. The router is connected behind the broadband device and works as a NAT or IP router for broadband and ISDN connections.
In addition to broadband access capabilities, the ISDN port can do dial backup, or provide remote access and remote management functions to support more flexible network connectivity. The following application scenario shows that the head office is capable of getting on to the Internet through the
