Cross-connection scheduling capabilities supported by ND2 boards

3

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

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).

Whether a cross-connect board is required when ND2 is used to achieve electrical regeneration
The cross-connect board is not mandatory in this scenario. If the cross-connect board is configured, you can configure pass-through services to achieve electrical regeneration. If no cross-connect board is configured, you can configure ND2 in electrical regeneration mode to achieve regeneration of OTU2 and OTU2e signals.

Whether regeneration is supported on ND2 boards
ND2 boards can regenerate one channel of OTU2/OTU2e signals in both directions.

Whether two GE services on two TOM boards can be cross-connected to the same ODU1 timeslot on an ND2 board
The cross-connections between the TOM and ND2 boards are ODU1 cross-connections, which occupy the entire ODU1 timeslot. Therefore, two GE services on two TOM boards cannot be cross-connected to the same ODU1 timeslot of an ND2 board.
