Definitions:
CRC4: – Cyclic redundancy check indicating errored submultiframes received on the E1 side;
E-bit: – CRC4-indication bit denoting received errored submultiframes received on the E1 side;
FAS: – Errored frame alignment signal received on the E1 side;
Errored Block (EB): – A block where one or more bits are errored;
Errored Second (ES): – A one second period with one or more errored blocks or at least one
defect;
Severely Errored Second (SES): – A one-second period, which contains more than 805 error
blocks per second (if CRC4 options are enabled) or the number of errored framed alignment is
more than 28 per second. SES is a subset of ES;
Background Block Error (BBE): – An errored block not occurring as a part of SES.
Errored Second Ratio (ESR): – The ratio of ES to total seconds in available time during a fixed
measurement interval;
Severely Errored Seconds Ratio (SESR): – The ratio of SES to the total number of error-free
seconds in available time during a fixed measurement interval;
Background Block Errored ratio (BBER): – The ratio of BBE to the total number of error-free
seconds in available time during a fixed measurement interval;
Available time: – The period when measurements of the parameters are possible;
Unavailable time:– The period when the measurements of the parameters are impossible.
4.6.3.6 <ALLG826> command
The <ALLG826> command displays the ITU-T G.826 performance parameters of the
line for the local and remote modules and for regenerators.

CO_PM>
Please see the previous chapter for the explanation of the different parameters.
4.6.3.7 <RESETG826> command
The <RESETG826> command clears the ITU-T G.826 error performance parameter counters.
4.6.3.8 <RESETALLG826> command
The <RESETGALL826> command will clear the ITU-T G.826 performance counters on the
xDSL interface of the local module, all regenerators connected to it and on the remote unit.
