FUNCTIONAL DESCRIPTION (CONT’D)
Condition
Type
Action
A prestored LIN-BN-LOUT combination is found in the RIF &
that LOUT has occurred only once in the RIF.
Copy frame. Signal MAC Interface.
A prestored LIN-BN-LOUT combination is found in the RIF &
that LOUT has occurred more than one time in the RIF.
Discard frame. Signal MAC Interface.
Increment DUPLOUT counter.
No prestored LIN-BN-LOUT combination is found in the RIF.
#RDs ≥ SRFRD
Discard frame. Signal MAC Interface.
Discard frame. Signal MAC Interface.
Discard frame. Signal MAC interface.
Copy frame. Signal MAC Interface.
Prestored LIN is found more than once in the RIF.
LTH = 2
Last LOUT in RIF ≠ LIN, LTH ≠ 2
Discard frame. Signal MAC Interface.
Increment LANIDMISMATCH
counter.
#RDS ≥ ARERD
Discard frame. Signal MAC Interface.
Increment ARERDLIMITEXCEEDED
counter.
Not all prestored LOUTs in RIF
#RDS < ARERD
Copy frame. Signal MAC Interface.
All prestored LOUTs in RIF, LTH ≠ 2
LTH = 2
Discard frame. Signal MAC Interface.
.
Copy frame. Signal MAC Interface.
Last LOUT in RIF ≠ LIN, LTH ≠ 2
Discard frame, Signal MAC Interface.
Increment LANIDMISMATCH
counter.
#RDS ≥ STERD
Discard frame. Signal MAC Interface.
Increment STERDLIMITEXCEEDED
counter.
Not all prestored LOUTs in RIF
#RDS < STERD
Copy frame. Signal MAC Interface.
All prestored LOUTs in RIF, LTH ≠ 2
Discard frame. Signal MAC Interface.
Increment DUPLANIDORTREEERROR
counter.
Bit DISSTE = ONE
Discard frame. Signal MAC Interface.
Note: Signalling takes place at the end of the RIF. Discard actions overrule copy actions. The result of the SRB is
OR’ed with the result of Routine 2, whereby the copy action overrules.
