Generally, X.25 or PSTN can be used for DDN line backup.

Ii. CISCO router Wan Configuration Wizard
1. dial-on demand routing (ddr) is a network connection provided by a public telephone network.
Generally, most WAN connections use leased lines. routers connect to DCE devices similar to modem or isdntas. They support synchronous V.25BITS protocol. You can use the scripts and dialer commands to set the
peer- to-peer user name and password for CHAP authentication.ISDN1 (config) #int loopback 0// go to change back port 0ISDN1 (config-if) #ip Add 1.1.1.1 255.255.255.0// Configure IP AddressISDN1 (config-if) #exitISDN1 (config) #isdn switch-type basic-net3// defining interchange types for ISDNISDN1 (config) #int BRI 0// Enter the base rate interface 0ISDN1 (config-if) # IP Add 12.1.1.1 255.255.255.0// Configure IP AddressISDN1 (config-if) #encapsulation PPP// Configure the package format for the
corresponding interface mode, where 1 corresponds to the dial-pool-number dialing pool number ). If you enter pppoe-client dial-pool-number 1 no-ddr, the system performs automatic connections during dial-up. When you start the system, the system will dial up instead of dialing as needed.
Step 4: In addition to enabling the dialing process and function on the physical port, we also need to set the PPPOE Virtual Interface. All PPP negotiation for PPPOE dialing is based on the logical interface. I
connection, you do not have to do this configuration.
2. Configure Dialer Interface
In the AR G3 router, regardless of which ADSL connection mode, ADSL PPPoE dial-up are controlled by DCC, so need to configure DCC parameters. Because the ADSL interface can only work in the shared DCC mode, it can only be configured with DCC parameters on the logical dialer interface, including the IP address assignment of
Fiber-optic access broadband is faster and more stable than ADSL transmission, so many friends now choose the fiber-optic access when they install broadband. But when I installed the FTTB dialer under Windows XP, I encountered a problem:

In Windows XP, follow the steps under Windows 98 to install the FTTB private dialer and enter your username and password, and the system requires
This article uses the GPRS module in Linux to implement wireless Internet access. The code and method are difficult to understand, so you must read the code patiently. I believe you can learn a lot.

3. configure the PPP dial-up network with a script
I first wanted to run pppd to connect to the dial-up network, but soon I found it too troublesome because there were too many options. Later, I found that several PPP dialing program templates have been provided on Linux. you only need to slightly modify these templates to easily connect them to PPP. Based on my experience, the configuration can be completed in 10 minutes if it succeeds.

ADSL network components. In order to improve the working stability of ADSL modem equipment, we should choose the workstation with Windows XP SP2 operating system as the dial-up host, because the system has the best compatibility to ADSL related equipment, and the stability of ADSL modem equipment is the best when working under the system. Of course, if we do need ADSL dial-up Internet access under the Windows 98 operating system, it's best to download a dedicated stop-through patch on the web,
