Cross-connect capability of the TN16UXCM board

12

The TN16UXCM board supports cross-connect grooming of ODUk (k = 0, 1, 2, 2e, 3, 4, or flex) signals and VC-4/VC-12/VC-3 signals and packet switching of Ethernet services. The maximum grooming capability is 640 Gbit/s (the capability is increased to 1.28T in V100R007C02).

Cross-connection scheduling capabilities supported by ND2 boards
The service scheduling capabilities vary according to the versions of ND2 boards. The details are as follows: TN11ND2/TN12ND2: 8 x ODU1, 2 x ODU2, 2 x ODU2e TN52ND2T01/TN52ND2T02/TN52ND201M01: 16 x ODU0, 8 x ODU1, 2 x ODU2, 2 x ODU2e TN52ND2T04/TN53ND2/TN57ND2: 16 x ODU0, 8 x ODU1, 4 x ODUflex, 2 x ODU2, 2 x ODU2e

Reason why the cross-connect board must be TN16UXCM when the TTX board is used in an OptiX OSN 8800 T16 subrack
The TTX board processes 10 x 10G signals and therefore requires a 100 Gbit/s cross-connect capacity on the backplane. An OptiX OSN 8800 T16 subrack supports the 100 Gbit/s cross-connect capacity in a single slot only when the TN16UXCM board is configured as the cross-connect board.

Cause for the failure to create ODU1 cross-connections on TN52TOM boards on OSN 6800 (without cross-connect boards)
The TN52TOM board does not support distributed ODU1 cross-connections.

ODU1 cross-connections failing to be created on the TN52TOM board of OSN 6800 where no cross-connection is configured
The TN52TOM board does not support distributed ODU1 cross-connections.

Cross-connection level of the services on the TOM board
ODUk cross-connections are configured on the TOM board. For details about the service grooming mode in each scenario, see the multimedia in "Logical Ports" in the product documentation.
