The only difference lies in internal port names.

Whether ODU2 services are generated when ODU1 bidirectional pass-through services are configured on the 53NQ2 board in OptiX OSN 8800
No. ODU2 services will not be automatically generated.

Whether the multiplexing from four ODU1 signals to one ODU2 signal is similar to the SDH multiplexing (both implemented in byte interleaved mode)
Yes. Both are implemented in byte interleaved mode.

Differences between IN_PWR_LOW differ from IN_PWR_ABN
IN_PWR_ABN is the predecessor of IN_PWR_LOW/IN_PWR_HIGH. Due to historical reasons, both alarms exist in the OptiX OSN 8800.

Differences between TE40 and TE30 usage scenarios
Compared with TE30, TE40 has higher performance and more ports. TE40 is a good choice for holding video conferences in medium- or small-scale conference rooms and office rooms. Example: TE40 supports a maximum of 8 Mbit/s call bandwidth, while TE30 supports a maximum of 4 Mbit/s call bandwidth. TE40 supports a maximum of 1080p60 image resolution, while TE30 supports a maximum of 1080p30 image resolution. TE40 supports three video input ports, while TE30 supports two. TE30 adopts an all-in-one design that that integrates digital cameras and stereo microphones, satisfying the demand of senior managers to attend video conferences in administrative offices or small-sized conference rooms.
