EtherBERT Test Setup and Results
NetBlazer
107
Summary Results
Start Time

Start Time : The time when the EtherBERT test was started.
Pattern

Pattern Loss : Alarm is raised when the bit error rate is above 0.2.

No Traffic
: Alarm is raised when there is no traffic for a period
specified by the No Traffic Time configuration. Since the monitoring
starts at the beginning of the test, this alarm is in an undefined state for
the time configured in the
No Traffic Time field after a test case is
started.

RX Rate : Displays the receive rate in terms of a percentage of the line
rate(
%
),
Mbit/s
, or in
Gbit/s
.

TX Rate : Allows to set the transmission rate in terms of a percentage of
the line rate (
%
),
Mbit/s
, or in
Gbit/s
. The accepted values are as
shown in table Max. Rate on page 82.
BER

Bit Error : A bit error indicates that there are logic errors in the bit
stream. (i.e. zeros that should be ones and vice versa).

Mismatch ‘0’ : A mismatch ‘0’ error indicates a bit error on a binary ‘0’
(i.e.ones that should be zeros) found in the receiving test pattern only.

Mismatch ‘1’ : A mismatch ‘1’ error indicates a bit error on a binary ‘1’
(i.e. zeros that should be ones) found in the receiving test pattern only.
Note: The errors are monitored only on the Test Pattern and not on the Ethernet
frame header, CRC, Preamble, or Idle code-group.
