Pattern
The pattern setup appears when OTN Mapping is set to a PRBS Test Pattern.
Pattern Setup
PRBS Pattern:
Use the pattern drop-down box to select the test pattern which will be inserted into the transmitted signal.
Pseudo Random Bit Sequences (PRBS) defined by ITU-T 0.150 and 0.151 standards, fixed words and 24-bit or 32 bit
user defined patterns are available.
Note: If the 32 bit user pattern entered is incorrect, the default pattern will be
0xFFFFFFFF.
Invert:
Inversion of PRBS polarity is also available. Inversion of fixed words is not permitted.
Out of Service:
Should be selected if the incoming signal is expected to contain a known test pattern. Deselect this option
if
signal is expected to contain live network traffic – this will disable the pattern detection process and will enable the
reporting of
LSS.
