Modem Initialization Strings

This appendix 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. SeeTable 3Table 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.

All Telebit modems need to have the speed set explicitly. These examples use 38400 bps. Using what Telebit calls "UNATTENDED ANSWER MODE" is the best place to start a dial in only modem.

*NA*

This option is not available on the noted modem.

-->

The command noted on the right will handle that function.

The command noted on the left will handle that function.

AUX port

These parameters are only required for pre-9.21 AUX ports or any other port without modem control set.


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.
