8.4.1 G.826 Statistics
G826 [ C ]
The G826 command displays the ITU-T G.826 error statistics on the DSL line
side of the local and remote DSL unit. G826 C will continuously update the dis-
play. The G.826 statistics are calculated from CRC6 errors.

Errored blocks
A block in which one or more bits are in error
Errored seconds
One second periods with one or more errored blocks
Severely errored
seconds
One second periods with more than 30% errored
blocks
ESR
Errored seconds ratio. The ratio of errored seconds
to seconds in available time
SESR
Severely errored seconds ratio. The ratio of severely
errored seconds to seconds in available time
BBER
Background block error ratio. The ratio of errored
blocks to total blocks, excluding all blocks during se-
verely errored seconds and unavailable time
Available time
Time without errors, with errored seconds and with
less than 10 consecutive severely errored seconds.
Unavailable time
A period of unavailable time starts with 10 consecu-
tive severely errored seconds. These 10 seconds
are considered to be part of unavailable time. A new
period of available time begins with 10 consecutive
non-severely errored seconds. These 10 seconds
are considered to be part of available time.
