Note The y argument value is the actual slot number of the VISM card. Always type 1 for port
argument value, which represents the line nu mber in this configuration. VISM-PR cards

loop-detection argument values, and press Enter to configure the clocking option defined in Step 2 on
your VISM card. Specify the arguments with the following values:
•line-num: In the range from 1 to 8
•line-code:
