87L DIFF KET DTT operand, which
becomes on when the differential
element is sending direct transfer trip to
the remote terminals.
87L DIFF PFLL FAIL operand, which
becomes on when the differential
element's phase and frequency lock loop
(PFLL) has failed.
87L DIFF CH ASYM DET operand, which
becomes on when the differential
element's has detected substantial
communications channel asymmetry.
87L DIFF CH ζ FAIL operand, which
becomes on when the differential
element's has detected communications
channel ζ failed.
87L DIFF CHζ LOSTPKT operand, which
becomes on when the differential
element's has detected the lost packet
threshold has been exceeded on channel
ζ.
