Modem Initialization Strings
This document provides tables that contain modem initialization strings and sample modem initialization scripts. Table 1 lists required settings, and error compression (EC) and compression settings for specific modem types. Use this information to create your modem scripts. Table 2 lists information for setting AUX ports. SeeLegend to Symbols Used in Modem Chart Table 3 for a legend of symbols used in these two tables. Sample scripts follow the tables.
For information about configuring lines to support modems, see the chapters in the part “Modem and Dial Shelf Configuration and Management” in this publication.

Sample Modem Scripts
The following are several modem command strings that are appropriate for use with your access server or router. For use with the access server, Speed=xxxxxx is a suggested value only. Set the DTE speed of the modem to its maximum capability. By making a reverse Telnet connection in the EXEC mode to the port on the access server where the modem is connected, then sending an at command followed by a carriage return.
In the following example, the modem is attached to asynchronous interface 2 on the access server. The IP address indicated as the server-ip-address is the IP address of the Ethernet 0 interface. The administrator connects from the EXEC to asynchronous interface 2, which has its IP address assigned from Ethernet 0.
