commands in the chat scripts you select as the Dial-Out Script and/or Dial-back Script.

ϖNote: Please check the manual for the communications device you are using to determine the best available dialing method for this interface.

ϖNote: Compatible Systems routers support “chat scripts” which let you provide a sequence of commands (using chat “send” statements), and antic- ipated responses (using chat “expect” statements) to devices which need to be dialed.

Dial-Out / Connect Script

This pull-down menu selects the main chat script the router will run when attempting to initiate a connection.

You may choose any of the chat scripts which have been configured into the router. For more information on creating chat scripts, see the section on the Chat Script Editor Dialog Box later in this manual.

•If you selected the On Demand PPP Link pulldown discussed earlier, this pulldown will be labeled Dial-Out, and you must select a chat script here. The chat script you select will be executed whenever dialing is initi- ated.

•If you selected the Dedicated PPP Link or Frame Relay Link pulldown discussed earlier, this pulldown will be labeled Connect, and you may optionally select a chat script here. This script will be run when the router starts up and again whenever PPP communications are lost for some reason, and can be used to provide a set of required connect responses to a device (such as a terminal server) at the other end of the dedicated line.

Dial-back Script

This pull-down menu provides a way to select a chat script which will provide global dial-back security on incoming connections to this interface. This option can only be used if you have checked both the Allow Dial Out and Allow Dial In boxes discussed above.

You may use this menu to choose any of the chat scripts which have been configured into the router. For more information on creating chat scripts, see the section on the Chat Script Editor Dialog Box later in this manual.

•If you select a chat script here, the router will accept a PPP dial-in connection and then automatically drop the link and initiate dialing using the chat script you have selected.
