Description of the problem

OSN3500 SNCP multi-ring tangent with upstream SNCP inversion triggers SNCP multi-level inversion. Use the meter to test this service, and the meter will reflect the inversion overrun.

Processing

None

root cause

none

Solution

The reason for the long SNCP inversion time is due to the fact that before the first SNCP inverts, it transmits alarms to the downstream SNCP, and this SNCP then inverts. The downstream SNCP will also transmit alarms to the downstream SNCP first, and then this SNCP will be inverted, and so on, and the downstream SNCPs may all be inverted. This way the service shows a period of time on the also meter side to break a good ...... , the meter inversion test will consider it as a long short, so much so that the service overruns. See the documentation for more information.

Recommendations and Summary

Configuration requirements for SNCP multi-ring tangent sites:

(1) Configure the working and protection paths of the two sets of homologous SNCP protection at the SNCP ring tangency site to be opposite.

(2) Configure the SNCP service of the two homologous SNCP services at the SNCP ring tangency point to be restored.
