Explanation

Action

 

 

 

36

Address Verification, Ring Failure: The PC Card,

1 and 2a

 

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.

 

 

 

 

37

Address Verification, Ring Beaconing: The PC Card

1 and 2b

 

has either detected a monitor greaster than or equal

 

 

to contention (claim token) failure or received a

 

 

beacon greater than or equal to MAC frame from

 

 

the ring.

 

 

 

 

38

Address Verification, Duplicate Node Address: The PC

4

 

Card has detected that another station on the ring

 

 

has a PC Card address that is the same as the PC

 

 

card address being tested.

 

 

 

 

3A

Address Verification, Remove Received: The PC Card

2a and 4

 

has received a remove ring station MAC frame,

 

 

indicating that a network management function has

 

 

directed this specific address to get off the ring.

 

 

 

 

42

Ring Poll, Signal Loss: The PC Card has detected a

1 and 2a

 

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.

 

 

 

 

45

Ring Poll, Time Out: The insertion timer expired

1 and 2a

 

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.

 

 

 

 

46

Ring Poll, Ring Failure: The PC Card, acting as an

1 and 2a

 

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.
