Command
C
Display Counters: Counts the number of FE, CRC, FEBE, and HDB3V errors.
• Frame Bit Error (FE): An error in the received framing bit pattern and the number of whole
seconds in which a framing bit error has occurred.
• Cyclic Redundancy Check (CRC) is an error-checking algorithm performed on data
transmissions. On a frame-by-frame basis, a numerical value is derived from the data in
the bit stream at the transmit end. When each frame reaches the receive end, the cyclic
redundancy check is calculated again and compared with the value generated by the
transmit-side data. Discrepancies indicate one or more transmission errors.
• FEBE: Far End Block Errors: Counts the CRC errors reported by the far-end CSU.
• HDB3V: High Density Bipolar (order of 3) Violations indicate an HDB3 line coding error.
Rn
Reset Counters: Returns the values of the FE, CRC, FEBE, and HDB3V counters to zero.
