Details
The test can only be performed
when the link is down. If the
link partner is trying to auto-
negotiate or if the link partner
is sending out idle link pulses,
the test will proceed.
The twisted pair under test is
specified in register 22.
The twisted pair under test is
specified in register 22.
The distance is given in meters
by 13/16 * (decimal equivalent
of 28.7:0) + 32 .The twisted
pair under test is specified in
register 22. If no short or open
is detected, these bits are 0’s.
