Sample ttgen Configuration File

The /opt/acc/cfg/loopback.answ file is a sample ttgen configuration file. The sample file is automatically created when the ACC product is installed. The MUX-Definition statements in this file are created to match the hardware that is installed on the system at the time the file is created. In the case that the ACC multiplexer cards are moved within the system after the product is installed, it may be necessary to either manually modify the loopback.answ file, or to recreate the file to reflect the new hardware location.

The file may be recreated by running:

% cd /opt/acc/cfg % /opt/acc/lbin/acc_bld_lpbk -t sample_header \ -o loopback.answ

Once the configuration file is created or modified, the ttgen utility must be run to create a downloadable file:

% ttgen -o loopback.answ loopback.tmem

The following is an example of a file created by the acc_bld_lpbk script on a system that has two NIO ACC multiplexer cards, an 8-Channel and a 2-Channel card installed:

The /opt/acc/cfg/loopback.answ file will be created whether or not there are ACC interface cards on the system at the time acc_bld_lpbk is run. In the case that there are no ACC interface cards installed, the loopback.answ file will be similar to the one shown, except that there will be no Mux, Port, or Term statements. The /opt/acc/cfg/loopback.tmem will also still be created, and can be used to bring up the ACC MUX Subsystem.

Refer to the ACC Utilities Reference Guide for more information on the format of the .answ file, and on running ttgen to create the .tmem files.
