2.1.9.8 SNCs
One ONS 15600 SONET NE supports a maximum of 1536 STS SNCs.
2.1.9.9 Protection
The ONS 15600 SONET supports 1+1 protection to create redundancy for optical ports. Protect
ports must match the working ports. For example, port 1 on an OC-48 card can be protected
only by port 1 on another OC-48 card.
ports must match the working ports. For example, port 1 on an OC-48 card can be protected
only by port 1 on another OC-48 card.
2.1.9.10 Autodiscovery
The ONS 15600 SONET supports automatic discovery of connected elements. Prime Optical can
connect to one node and retrieve information about all connected nodes. The first time Prime
Optical connects to a node, it retrieves only the IP address of the connected node; Prime
Optical does not retrieve the node name. However, Prime Optical must report this element to
the users. Because the IP address is unique, Prime Optical initializes the name of the newly
discovered element with the IP address. An object creation event is generated for this managed
element with the IP address as the name. Later, Prime Optical connects to this element and
retrieves all information, including the actual name, and an AVC event is generated for the
managed element name. The NMS listens to the AVC event for the managed element name and
invokes managedElementManager::ManagedElementManager_I:: getManagedElement.

2.1.10 ONS 15600 SDH
Prime Optical 9.8 supports.
2.1.10.1 Slots
The ONS 15600 SDH is a single-shelf NE with 14 slots. The TSC card must occupy slot 5 or slot
10. The 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. SSXC cards replace CXC cards
from release 5.0 of the NE. For more information, refer to the Cisco ONS 15600 SDH user
documentation.

2.1.10.2 Topological Links
Topological links are unidirectional or bidirectional for ONS 15600 SDH NEs.
2.1.10.3 PTPs
All PTPs are bidirectional for the ONS 15600 SDH. These ports are always in channelized mode.
PTPs support In Service and Out of Service–Maintenance values for the service state attribute.
