Port Type
The type of port. Possible port types are A_Port,
B_Port, Slave, or Master.
Link Error Rate Estimate
The link error rate estimate is a cumulative long-
term average of the bit error rate, which
represents the quality of the physical link. The
link error rate estimate is computed when the
port is connected and every 10 seconds thereafter.
It ranges from 10
-4
to 10
-15
and is reported as a
whole integer. For example, if the port’s link error
rate estimate is computed to be 10
-5
, the value
reported in this field would be 5, which represents
an actual rate of 1,250 bit errors per second. A
lower link error rate estimate indicates a higher
bit error rate as shown in Figure 12.
