Whether services on the TOM board and TOA board can be interconnected
Yes, they can be interconnected on the OSN 8800 when the two boards have the same service type and mapping mode settings.

Service interconnection between TOA and TOG boards
Services on the TOA board can be interconnected with those on the TOG board.

Mode used by the TOA board to connect to IPRAN devices
The GMP-TTT mode is recommended, so that synchronous Ethernet transparent transmission is supported.

Working mode of the TOA board when ODU0 services are configured on the board
When ODU0 services are configured, the working mode of the TOA board must be set to ODU0 non-convergence mode (Any -> ODU0).

Interconnection mode between TOA and IPRAN
In GMP-TTT mode, synchronous Ethernet transparent transmission is supported.
