This counter incrementes when the TBC hears an unexpected frame when expecting a response to a transmitted request with response frame. An unexpected frame in this case is any valid frame which is not a response frame addressed to this station. Upon detecting this event, the TBC increment this counter and goes to the IDLE without passing the token.
OBJECT-TYPE    
  Counter  

tbUnexpectedFrame10s 1.3.6.1.4.1.495.2.1.5.9.2.22
The TBC module incremented this counter when it executes the 'unexpected frame 10' transition the IEEE 802.4 access control machine (ACM). It occurs when the TBC attempted to solicit a new successor and while waiting for a response, heard either a data frame not sent by itself. When this event occurs, it indicates a protocol error, possibly a duplicate token situation. After this event, The TBC will go to the IDLE without passing the token.

tbNbNoSuccessor8Passes 1.3.6.1.4.1.495.2.1.5.9.2.28
This statistic indicates the number of times this station has gone through the no successor 8 arc in the state machine. This happens when the TBC fails to pass the token and does not succeed in finding a new successor station. The counter is incremented only if the TBC thinks it is not the only active station in the network. A significantly large value in this counter may indicate a 'faulty' transmitter condition in this station.

  Counter  

tbNbWhoFollowsFrames 1.3.6.1.4.1.495.2.1.5.9.2.29
This statistic is the number of times this station has had to look for a new next station to pass the token to. This frame is sent as part of the TBC's effort to pass the token to its former successor's successor if the original successor station does not respond to the token. This counter is incremented by two every time a failure occurs.
OBJECT-TYPE    
  Counter  

tbNbTokenPassFailures 1.3.6.1.4.1.495.2.1.5.9.2.30
This statistic indicates the number of token pass failed transitions when pass state is equal to pass token. Upon failing to pass the token, the TBC tries to send a second token (pass state equals repeat pass token). If this effort fails too, this counter is not incremented again; but the TBC will then send a who follows frame and the who follows query counter will be incremented.

tbRxFrameFragments 1.3.6.1.4.1.495.2.1.5.9.2.34
This statistic represents the number of frame fragments (start delimiter (SD) not followed by a valid end delimiter (ED)). A valid frame consists of only data (zero or one MAC symbols) between the SD and the ED. If an SD is detected and then, before a valid ED, the TBC detects either silence, non data (not part of the aligned ED), or bad signal, then this counter is incremented. Note that this includes abort sequences.
