G826 E1 [ C ]
The G826 E1 command displays the G.826 error statistics for the E1 interface.
Depending on the current configuration of the interface the G.826 values are cal-
culated differently. Use G826 E1 C for continuous display
If CRC4 mode is on the G.826 statistics are calculated by evaluating the CRC4
and the E-Bit:
LTU_01_PM> G826 E1
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
G.826 Error Performance : CRC4 E-Bit
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Errored Blocks : 00000000 00000000
Errored seconds : 00000000 00000000
Severely errored seconds : 00000000 00000000
ESR [%] : 0.00 0.00
SESR [%] : 0.00 0.00
BBER [%] : 0.00 0.00
Available time : 00524129 00524129
Unavailable time : 00000024 00000024
If CRC4 mode is off, the G826 statistics are calculated by evaluating the Frame
Alignment Signal (FAS) on the E1 side. The criteria for severely errored seconds
(SES) is 28 FAS-Errors per second (in accordance to G.821).

In PRA mode, the G826 E1 command displays the ITU-T G.826 error statistics
based on CRC4 and E-Bit evaluation on the T and the V3 reference points, see

Note:
The G826 E1 command is only available if option 2 (CRC4 processing) or op-
tion 4 (CRC4 monitoring) is selected in the configuration.
