Description
It configures the threshold value of one-way delay (in milliseconds) that causes the phone to send a warn-
ing alert quality report to the central report collector.
For example, if it is set to 500, when the value of one way delay computed by the phone is greater than or
equal to 500, the phone will send a warning alert quality report to the central report collector; when the
value of one way delay computed by the phone is less than 500, the phone will not send a warning alert
quality report to the central report collector.
If it is set to blank, warning alerts are not generated due to one-way delay. One-way delay includes both
network delay and end system delay.
