t1 bert
Syntax
t1 channel bert pattern pattern interval time [ unframed
]
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 unframed keyword, then the
test bit pattern occupies only T1 payload bits.
