Summary

This chapter is divided into two separate sections that cover dial design solutions and dial configuration solutions.

The dial design solutions section covered the essentials of dial-in network connectivity, dial-out network connectivity, and DDR along with dial-out for support purposes and large-scale dial-out services.

The dial configuration solutions section provided detailed information about common and specific dial configurations, including the following:

• Text dial-in configuration

• PPP dial-in configuration

• Large-scale dial-in configuration

• Text dial-out configuration

• PPP dial-out configuration

• Large-scale dial-out configuration

• Dial-on-demand backup configuration

Before the troubleshooting process starts, it is important to understand entirely the design and configuration specifics of the dial solution. This gives you a better understanding of the troubleshooting methodology that's used for dial in the next chapter.
