Display for the STATS LINE Command
For example, if the THRESHOLD value is 500, each 500 frames are compared to
the last block of 500 frames. If there are 5 errors (1 percent of 500), the line quality
drops to 99.
With a THRESHOLD value of 500, 0 to 4 errors gives 100 percent line quality, 5 to
9 errors gives 99 percent line quality, 10 to 14 errors give 98 percent line quality,
and so on. A change in value of less than 1 percent does not appear.
You may also wish to check console messages for line-quality changes.
You can change the threshold value with the X25AM I/O process modifier
LINEQUALITYTHRESHOLD (ALTER DEVICE command) or the THRESHOLD
attribute (ALTER LINE command). For information about the THRESHOLD
attribute, see Section 5, Attribute Descriptions.
