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

2.1.11.7 CTPs
All CTPs are in channelized mode for the ONS 15600 SONET. Alarm monitoring cannot be turned on or
off for CTPs.
off for CTPs.
2.1.11.8 SNCs
One ONS 15600 SONET NE supports a maximum of 1536 STS SNCs.
2.1.11.9 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.
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.
2.1.11.10 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.

2.1.12 ONS 15600 SDH
See the
Optical 10.6 supports.
2.1.12.1 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.
