Table 5-5 Actions for Open Errors
Error Code Explanation
11 Lobe Media, Function Failure: The testing of the lobe
between the PC Card and the access unit has been
unsuccessful because the lobe has a bit-error rate
that is too high, or the PC Card cannot receive
successfully.
24 Physical Insertion, Frequency Error: The PC Card has
detected that the ring is operating at a speed other
than the speed at which it was inserting.
26 Physical Insertion, Ring Failure: The PC Card, acting
as an active monitor, was unable to complete the
ring purge function successfully. This indicates that
an error condition has occurred since the successful
completion of monitor contention (claim token),
when this PC Card became the active monitor.
27 Physical Insertion, Ring Beaconing: The PC Card has
detected one of the following conditions:
2A Physical Insertion, Remove Received: The PC Card
has received a remove ring station MAC frame,
indicating that a network management function has
directed this PC Card to get off the ring.
2D Physical Insertion, No Monitor Detected: RPL station
is the first station attempting to insert onto the ring.
2E Physical Insertion, Monitor Contention Failed for RPL:
Physical insertion failure of RPL station.
32 Address Verification, Signal Loss: The PC Card has
detected a 250-ms signal loss (receiver cannot
recognize signal), indicating that an error condition
has occurred since the PC Card successfully
completed the ring signal recognition phase of the
open operation.
35 Address Verification, Time Out: The insertion timer
expired before this function was completed,
indicating that the ring may be congested,
experiencing a high bit error rate, or losing an
abnormally high number of tokens or frames, thus
preventing successful Address Verification MAC
frame transmissions.
(continued)
The PC Card tried to insert on a ring that was
operating at a different data rate.
A monitor contention (claim token) failure
occurred.
The PC Card received a beacon MAC frame from
thering.
