Pattern

Coupled RX to TX check box, when selected (default), couples both
the TX and RX signal with the same test pattern. The
Coupled RX to
TX check box is selected and not configurable for Seed A , Seed B , and
PRBS31 Unscrambled
patterns as well as for CPRI/OBSAI BERT test.

No Pattern Analysis (Live) check box when cleared (default; selected
by default for framed CPRI and eCPRI), monitors the incoming traffic
pattern and Round-Trip Latency. For live traffic, the
No Pattern
Analysis (Live)
check box should be selected as the traffic is a live
pattern and in this case no monitoring is required. Even if this check
box is not available for FC BERT, the received traffic pattern and
Round-Trip Latency are monitored. See
BER on page 396 for more
information.

TX Pattern/RX Pattern : Select the test pattern from the list for each
direction (TX and RX) if required. Choices are

, and User Pattern . Pattern is not configurable and set to
PRBS31
for eCPRI Framed Layer 2/3/4, 40/100GE dual port topology,
FlexE BERT, and 200GE/400GE test.
When
User Pattern
is selected, enter the payload pattern hexadecimal
value.

Invert
check box, when selected (cleared by default), inverts the
generated/expected test pattern meaning that every 0 will be changed
for 1 and every 1 for 0. For example, the pattern 1100 will be sent as
0011. Patterns
PRBS15 , PRBS23 , and PRBS31 are defined inverted as
per ITU standard but EXFO uses non-inverted patterns for Ethernet test
applications and EoOTN.
1. Only available for 10G LAN with
Unframed (Interop)

2. Only available for 1G optical with Framed Layer 1 (see Framing on page 134).
