Error Code Explanation Action
42 Ring Poll, 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. 1 and 2a
45 Ring Poll, Time-out: The insertion timer expired before
this function was completed, indicating that the ring
can be congested, experiencing a high bit-error rate,
or losing an abnormally high number of tokens or
frames. This prevents the PC Card’s successful
reception of either the ring poll request or response
MAC frame, or transmission of the required ring poll
response MAC frame. 1 and 2a
46 Ring Poll, 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. 1 and 2a
47 Ring Poll, Ring Beaconing: The PC Card has either
detected a monitor contention (claim token) failure or
received a beacon MAC frame from the ring. 1 and 2b
4A Ring Poll, 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. 2a and 4
55 Request Parameters, Time-out: The insertion timer
expired before this function was completed, indicating
that the ring can be congested, experiencing a high
bit-error rate, or losing an abnormally high number of
tokens or frames. This prevents successful
transmission of the request parameter MAC frame or
reception of either the set parameter 1 or set
parameter 2 MAC frame (required response to the PC
Card’s request). 1 and 2a
56 Request Parameters, 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 (when
this PC Card became the active monitor). 1 and 2a
57 Request Parameters, Ring Beaconing: The PC Card
has received a beacon MAC frame from the ring. 1 and 2b
59 Request Parameters, Parameter Request - Retry
Count Exceeded: The PC Card has detected that the
ring parameter server is present on the ring but that
the required response (set parameter 1 or set
parameter 2 MAC frame) was not received in the
allotted time. This indicates that the ring can be
congested, experiencing a high bit-error rate, or losing
an abnormally high number of tokens or frames. 1 and 2a
5A Request Parameters, 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. 2a and 4
