SONET BERT
1. Connect to the test interface using the following:
−Single-mode ber patch cord to connect to a OC-x
(SFP) or 10G (XFP) interface
−BNC to connect to a DS3 or STS-3 interface
2. Power on the unit
3. From the SONET Home menu, tap on the Setup menu
4. Congure the pull down menu elds.
−Select Operating Mode and Test Rate
Conguration
5. Tap the Clock Source
O p e r a t i n g M o d e :
Normal, Payload, or
Transparent
Test Rate: If the
network type is set to
SONET, rate choices
are STS-1 to OC-192
Clock Src: Internal,
External (SMA or 2nd RX
for balanced or AUX RX
for unbalanced), From
RX, Oset (±50 ppm)
6. Tap to return to the previous menu.

Conguration (cont’d)
8. Congure the Payload.
To configure fields that
require alpha or alpha-
numeric entry, such as
Frequency Offset and
STS channel selection,
a configuration keypad
will appear when the
applicable eld is selected.
Payload TX will appear
if Bulk selecon is OFF
in the Structure seng.
In Channel Selection,
enter the STS-N, VT-GRP,
VT-1.5 SPE channel.
Keypad will appear when
the eld is selected.
Mapping: Select the
mapping to test
Bulk: In bulk mode, the
entire VT container is lled
with a test pattern per ITU-T
0.181 recommendations
Tributary: Set to DS1, E1,
DS3, or E3 depending upon
mapping

9. Congure the Pattern.
10. Tap the Auto-cong button.
−A search for SONET signals at both the electrical or
optical inputs is performed to determine the signal
structure, signal type, rate, framing, pattern.
INVERT: Inversion of PRBS polarity is also available. Inversion of xed
words is not permitted.
Use the paern drop
down box to select
the test paern. PRBS,
xed words and 32 bit
user dened paerns
are available.
Conguration (cont’d)
Tap . If the
search is successful, a
“Complete” result will
be displayed.

Summary screen: Provides an overview of any alarms, errors
or signal failures.
Jump to SETUP menu – it will automatically stop the
measurements and go to the Setup screen.
Measurements are restarted. If the RX pattern eld is set to
AUTO, after the RESTART the RX will search for the incoming
pattern. Once the pattern is found, the TX will be congured
the same as the RX pattern detected. If the RX pattern cannot
be found, the RX will be set to LIVE mode and the TX will
send the pattern that it was congured to.

Errors/Alarms screen: The soft LEDs on screen are arranged
logically and depend on signal hierarchy, structure, payload and
framing selected. The soft LEDs have a tri-color function.
Results (cont’d)
Note: Tapping the individual soft LED will automatically link you to
the applicable results screen, which provides detailed information.
Green: No error or
alarm is present
Red: An error or
alarm condition
is detected and is
currently present
Yellow: Indicates a

Results (cont’d)
LEVEL – Loss of Signal
(LOS) and Saturation
(SAT) level for optical
signals is shown
graphically, including
the level measurement

signal frequency and
offset is measured
and displayed
−SONET current:
frequency of the
input signal
−Offset: difference
between the
standard rate and
the rate of the
input signal
−Min (ppm): difference between the standard rate and the
minimum deviation detected in the input signal
−Max (ppm): difference between the standard rate and
the maximum deviation detected in the input signal
