DI-304/DI-304M ISDN Remote Router
◊ Link Disable – Disables the ISDN dial-out function.
◊ Dialup 128Kbps – Uses both ISDN B channels for Internet access.
◊ Dialup BOD – BOD stands for bandwidth-on-demand. The router
will use only one B channel under low traffic situations. Once the
single B channel bandwidth is filled, the other B channel will be
dialed automatically. For more detailed BOD parameter settings,
refer to the
Advanced Setup group > Call Control and PPP/MP
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 DI-304/DI-304M and a
broadband device and connecting to the branch office via an ISDN network
simultaneously.
