2.1.11 ONS 15600 SONET
See the Release Notes for Cisco Transport Manager Release 9.2 for the ONS 15600 SONET software
releases that CTM R9.2 supports.
2.1.11.1 Slots
The ONS 15600 SONET is a single-shelf NE with 14 slots. The Timing and Shelf Control (TSC) card
must occupy slot 5 or slot 10. The Core Cross-Connect (CXC) cards are always 1+1 redundant in
slots 6/7 and 8/9. Each CXC card occupies two slots. Slots 1 to 4 and 11 to 14 are reserved for optical
I/O cards. Single Shelf Cross-Connect (SSXC) cards replace CXC cards from release 5.0 of the NE.
However, due to a known caveat (CSCse87505), CTM and CTC display SSXC cards as CXC. For more
information, refer to the Cisco ONS 15600 SONET user documentation.
2.1.11.2 Equipment
All cards in the ONS 15600 SONET R5.0 and later display administration and service states. For earlier
software releases, these states are not applicable and CTM displays them as N/A.
