BERT state:(stopped)
e1 bert
Use e1 bert to enable BERT test for an E1 channel created on a CE3 interface.
Use undo e1 bert to disable BERT test.
Syntax
e1 line-number bert pattern { 2^11 | 2^15 | 2^20 | 2^23 | qrss } time number [ unframed ]
undo e1 line-number bert
Default
No BERT test is performed.
Views
CE3 interface view
Default command level
2: System level
Parameters
line-number: E1 channel number, in the range of 1 to 28.
pattern: Specifies BERT test mode, which can be 2^11, 2^15, 2^20, 2^23, and QRSS.
2^11: Specifies the code stream transmitted is the 11th power of 2 bits in length.
2^15: Specifies the code stream transmitted is the 15th power of 2 bits in length.
2^20: Specifies the code stream transmitted is the 20th power of 2 bits in length.
2^23: Specifies the code stream transmitted is the 23rd power of 2 bits in length.
qrss: Specifies the code stream transmitted is the 20th power of 2 bits in length and the number of
successive 0s in the code stream is no more than 14.
time number: Sets the duration (in minutes) of a BERT teat. The number argument is in the range of 1 to
1,440.
unframed: Sets the overhead bits of the padding frames for BERT test.
Usage guidelines
Multiple BERT test modes exist, as defined in ITU O.151, ITU O.153, and ANSI T1.403-1999. 2^11, 2 ^ 15 ,
2^20, 2^23, and QRSS are available on E1 channels created on CE3 interfaces.
To perform a BERT test, the local end transmits test data stream, which is returned after reaching specific
nodes. The local end then checks for the bit error rate by comparing the returned data stream with the
original, through which the state of the link can be determined. BERT test requires that data stream can
be looped back on specific nodes. You can achieve this by enabling remote loop back on the peer.
You can use the bert command to set the test mode and the test duration. During the process of a BERT
test, you can check the state and the result of the test. For more information, see the command that
displays information about a CE3 interface.
Examples
# Perform BERT test in QRSS mode on E1 channel 1 created on CE3 2/0/0 interface, setting the duration
to ten minutes.
