t1 channel bert pattern pattern interval time [ unframed ]
no t1 channel bert
Command introduced before JunosE Release 7.1.0.
Enables bit error rate tests using the specified pattern on a T1 line on a CT3 module. The
no version stops the test that is running.
channel—One or more individual T1 channels, ranges of T1 channels, or combination
of individual channels and ranges, in the range 1–28 (no spaces); for example,
3,7-15,19-13,27
pattern—One of the following test patterns
0s—Repetitive test pattern of all zeros, 00000...
1s—Repetitive test pattern of all ones, 11111...
2^11—Pseudorandom test pattern, 2047 bits in length
2^15—Pseudorandom test pattern, 32767 bits in length
2^20-O153—Pseudorandom test pattern, 1048575 bits in length
2^20-QRSS—Pseudorandom QRSS test pattern, 1048575 bits in length
2^23—Pseudorandom test pattern, 8388607 bits in length
alt-0-1—Repetitive alternating test pattern of zeros and ones, 01010101...
time—Duration of the test in the range 1–1440 minutes
unframed—Specifies that the test bit pattern occupies all bits on the link, overwriting
the framing bits. If you do not specify the unframed keyword, then the test bit pattern
occupies only T1 payload bits.
