tests can only be the default one, none.
• Only the test-complete keyword is supported for the reaction trap command in a voice test.
Configuring the NQA statistics collection function
NQA groups tests completed in a time period for a test group, and calculates the test result statistics. The
statistics form a statistics group. To view information about the statistics groups, use the display nqa
statistics command. To set the interval for collecting statistics, use the statistics interval command.
When the number of statistics groups kept reaches the upper limit and a new statistics group is to be
saved, the oldest statistics group is deleted. To set the maximum number of statistics groups that can be
kept, use the statistics max-group command.
A statistics group is formed after the last test is completed within the specified interval. Statistics groups
have an aging mechanism. A statistics group is deleted when its hold time expires. To set the hold time
of statistics groups for a test group, use the statistics hold-time command.
Follow these steps to configure the NQA statistics collection function:
