D-Link DI-304 Инструкция по эксплуатации онлайн [40/105] 41902

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.
