a: k = 0, 1, 2, 2e, 3, 4 or flex. Only the TN16UXCM supports ODU4 granularities.
b: All service slots share a bandwidth of 20 Gbit/s.
c: Theoretically, the subrack supports grooming of a maximum of 800 Gbit/s packet
services. In practice, however, the packet service grooming capability of the subrack is
determined by packet boards. The current version provides a packet service grooming
capability up to 640 Gbit/s.
The maximum OTN service cross-connect capacity of each slot can be expanded from 40
Gbit/s to 100 Gbit/s by replacing the cross-connect boards in the subrack.
