Reason why the cross-connect board must be TN16UXCM when the TTX board is used in an OptiX OSN 8800 T16 subrack

5

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.

Cross-connect capability of the TN16UXCM board
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).
