ESULTS
A PASS* or FAIL* result indicates that a measured NEXT or attenuation
value is close enough to the Test Standard that it is within the measurement
uncertainty of the SCAN-LAN Vt. As a result, the PASS or FAIL judgment
is uncertain, and therefore the SCAN-LAN Vt cannot determine with
confidence whether the link conforms to the Test Standard.
The following steps may be taken in order to resolve link tests with
marginal measured results:
