2.1.12.4 CTPs
All CTPs are in channelized mode for the ONS 15600 SDH. Alarm monitoring cannot be turned
on or off for CTPs.
on or off for CTPs.
2.1.12.5 SNCs
One ONS 15600 SDH NE supports a maximum of 1536 VC4 SNCs.
2.1.12.6 Protection
The ONS 15600 SDH supports 1+1 protection to create redundancy for optical ports. Protect
ports must match the working ports. For example, port 1 on an STM-16 card can be protected
only by port 1 on another STM-16 card.

only by port 1 on another STM-16 card.
2.1.12.7 Autodiscovery
The ONS 15600 SDH 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.

2.1.13 Carrier Packet Transport 200/600 SONET/SDH
Prime Optical manages the following NE types for the CPT System:
• CPT 200
• CPT 200 SDH
• CPT 600
• CPT 600 SDH
These NEs support a subset of the ONS15454 and ONS 15454 SDH features. The features are
limited to the card and port types listed in
• CPT 200
• CPT 200 SDH
• CPT 600
• CPT 600 SDH
These NEs support a subset of the ONS15454 and ONS 15454 SDH features. The features are
limited to the card and port types listed in
2.1.14 Unmanaged NEs
Unmanaged NEs are other vendor MEs in Prime Optical. There is no equipment for these NEs.
Prime Optical reports PTPs for unmanaged NEs only if a topological link originates from or
terminates on the unmanaged NE. There are no alarms reported for unmanaged NEs.

2.2 Prime Optical-Specific Details
2.2.1 Layer Rate
The following table reports the layer rates supported by Prime Optical. The layer rates are used for
tasks such as link and circuit management, PM retrieval, port provisioning, and alarm handling. The
Comments column contains further details on usage. Layer rates numbered 0 to 91 are TMF-defined,
and layer rates numbered 92 and above are Prime Optical-defined.
