Usage guidelines
Table 24 Possible error types displayed in the output
Field Description
FRED Receive loss of basic frame alignment, or receive frames with red alarm errors.
COFA Change of frame alignment.
SEF
Severely error frame. Four consecutive frame synchronization errors generate one
SEF.
FERR Framing Bit Error. It refers to frames with the Ft/Fs/FPS/FAS error.
CERR CRC error.
FEBE
Far end block error. This occurs when the CRC4 framing format applies on the E1
channel.
BERR PRBS bit error (pseudo-random binary sequence bit error, for test only).
BIP Bit-interleaved parity.
REI Remote error indication.
In this table, FRED, COFA, and SEF are called alarm errors (AERRs).
