Eclipse Edge Commissioning Tests
Tests are described for:
• BER Test for Edge
• Background Error Measurement for Edge
• Trib BER Measurement for Edge
• Fade Margin for Edge
• Protection Switching for Edge
BER Test for Edge
A BER test is applied to check that the link is passing traffic error free for the test
period; normally a minimum of 8 to 12 hours (overnight).
Two test methods can be employed:
• Background error measurement over radio paths; customer traffic is not affected.
Refer to
Background Error Measurement for Edge on page 3
.
• Tributary BER measurement, where customer traffic on a trib is replaced by a BER
test pattern. Refer to
Trib BER Measurement for Edge on page 3
.
Background Error Measurement for Edge
Eclipse provides background G.826 error measurements on the radio paths, from
ODU to ODU. Such tests run continuously in the background (in both directions).
• G.826 data capture is initiated in the Portal Performance screen. Refer to
Link
Performance on page 95
. A capture period can be started and stopped from this
screen. Refer to Aviat Networks’ Best Practices Guide for results interpretation.
• Historical G.826 error events are presented in the Portal History screen. Refer to
History on page 88
. Depending on its setting, the history screen displays error
occurrences within 15 minute blocks over seven days, or within 24 hour blocks over
one month.
Trib BER Measurement for Edge
Trib BER measurements can be made using an external BER tester, or the built-in
Eclipse capability.
Unlike a background measurement, which is single-link based, a trib test is used to
check a tributary circuit from end-to-end, meaning multiple links can be involved.
Built-in BER Test for Edge
The DAC 16x module includes a PRBS generator and a G.821 receiver to support
looped, and both-way tests on tribs:
