Displays the Facility Data Link (FDL) error statistics in both ANSI-403 and AT&T-54016
modes.
The tables display the following information:
DS1E1 FDL Errors -- ANSI-403 mode (first half):
ansi1 Displays only the first half of ANSI-403 mode FDL errors.
ansi2 Displays only the second half of ANSI-403 mode FDL errors.
att1 Displays only the first half of AT&T-54016 mode FDL errors.
att2 Displays only the second half of AT&T-54016 mode FDL errors.
Slot Slot identifier.
Conn Connector identifier.
CRC Counts Number of CRC-6 errors. The FDL calculates CRC-6 on the
incoming data. Each time the calculation does not match the
CRC-6 code word in the incoming enhanced super frame (ESF)
data stream, this count increments.
BPV Counts Number of bipolar (line code) violations. The FDL counts bipolar
violations whether its synchronizer is in sync or not. If the FDL is
set to receive B8ZS code words, it does not count these code words
as bipolar violations.
OOF Counts Number of out-of-frame errors. An out-of-frame error occurs
whenever two or more framing bits out of six in the Framing
Pattern Sequence (FPS) are incorrect. This event causes the FDL to
resynchronize to the incoming data stream.
FE Counts Number of individual bit errors in the FPS.
ES Counts Number of Errored Seconds (ES). An ES is any one-second time
interval with either a frame bit error or a CRC-6 error.
