182 Restrictions on OSN8800 Network Element Cross Capacity

ODU1_AIS.

Processing process

Upgrade version to 8800V1R2C00TR6 version.

Root cause

The configuration combination of NS3 + TSXL used in the present network is limited by the problem of 182 ODU1 level crossover capacity of 8800 sub-frame XCS due to software controlled inversion. When SNC protection switching is too much, the software will lose it and invalidate it. There are 144 ODU1 level crosses on the NS3 + 0 sub-frame used in the present network. The configuration of NS3 + TSXL protection switching requires 48 ODU1 level crosses, exceeding the limit of 182.
