no t1 channel bert
Release Information
Command introduced before JUNOSe Release 7.1.0.
Description
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.
Options
■
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
