Requirements for cross-connect boards and system control boards when packet service boards are used in OptiX OSN 8800

16

For an OptiX OSN 8800 T32 subrack, the cross-connect boards must be TN52UXCH or TN52UXCM and the system control boards must be TN52SCC if packet service boards are used. For an OptiX OSN 8800 T16 subrack, the cross-connect boards must be TN16UXCM if packet service boards are used.

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.

Requirement for cross-connect boards when the TQX board is used to transmit STM-64 services
No.

Whether packet service boards intended for OptiX OSN 8800 can be used in a slave subrack
Packet service boards intended for OptiX OSN 8800 can be used only in an independent subrack, but not in the a subrack configured in the master-slave mode.

Whether a system control board is required in an OSN 8800 platform subrack when it is used as a slave subrack
When an OSN 8800 platform subrack functions as a slave subrack, it does not require a system control board. Its IU17 and IU18 slots can be used to house service boards. When it functions as a master subrack, a system control board is required.

Packet board configuration for slave OptiX OSN 8800 subracks
At present, packet boards can be used only in an independent subrack, but not in the master or slave subrack when subracks are configured in the master-slave mode. When packet boards are configured in an OptiX OSN 8800 T32 subrack, the cross-connect board must be TN52UXCH or TN52UXCM, and the system control board must be TN52SCC in the subrack. When packet boards are configured in an OptiX OSN 8800 T16 subrack, the cross-connect board must be TN16UXCM in the subrack.
