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.
turned on or 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.

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
for the ONS 15600 SDH software releases
that Prime Optical 10.3 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.
