Glavno je da je radilo jel... svašta je moguce ali inace to bi trebalo bit ovako:
Citiraj:
CRC Errors - Cyclic Redundancy Check
Count of CRC errors. CRC is an error detection code used to verify packet transmission between the sender and receiving end. A CRC error indicates that part of the data packet is corrupt and requires retransmission.

Many CRC errors in a short period of time will show a noticeable reduction in throughput speed.

This can be an early indication that there is too much noise on the line and in extreme situations can lead to loss of sync (disconnection with the exchange).

Citiraj:
FEC Errors - Forward Error Correction
Count of errors that have been corrected due to error correction being applied to the line. Error correction is turned on at the same time as Interleaving.

Its normal to see FEC errors on an Interleaved line and rather than anything to be too concerned about its more an indication that the Interleaving & Error correction process is working and doing what it should. -
Citiraj:
HEC Errors - Header Error Check/Correction
Count of Hec errors. HEC is a type of CRC error check which has been performed on the header of an ATM Cell, but 1 bit errors can be corrected. This count is usually where HECs have been uncorrected and have been discarded.

If these errors are too high within a short period of time it will slow throughput... and could even lead to connection instability
