A standard deprecation period of one Prime Optical release is allowed on the obsolete APIs and 
data structure. However, Cisco is willing to consider exceptions that minimize the business 
impact to customers. 
2.2.4  Object Details 
2.2.4.1  Multilayer Subnetwork 
A subnetwork is a collection of managed elements that reflects network connectivity, in most 
cases. There are two ways to create a new subnetwork through the Prime Optical client: 
•  In the Domain Explorer window, choose File > Add Network Element(s). Choose <SELF> 
as the GNE ID and <System Default> as the subnetwork ID. Prime Optical creates a new 
subnetwork and assigns a name to the new subnetwork object. The naming convention is 
Subnetwork-ID, where ID = 00000001, 00000002, n. 
•  Create a subnetwork object from the Prime Optical client by choosing File > Subnetwork 
Explorer. In the Subnetwork Explorer window, select a network partition and choose File > 
Add New Subnetwork. Enter the subnetwork name. 
There are four ways to add NEs to subnetworks: 
•  Use the Prime Optical client to specify a subnetwork for the new NE. If the new NE is a 
GNE and you choose <System Default> as the subnetwork ID, the new subnetwork is created 
as described in the first bullet above. 
•  If the new NE is not a GNE, choose an existing subnetwork as the subnetwork ID. Prime 
Optical adds this NE to the subnetwork. 
•  If the new NE is connected to an existing NE on the network, Prime Optical discovers the NE 
and automatically adds it to the existing NE’s subnetwork. No user action is required.  
•  Use the Prime Optical client to move the NE from one subnetwork to another subnetwork.  
SNC creation is limited within a multilayer subnetwork scope. For example, assume 
Subnetwork-1 contains two NEs, A and B, that are connected to each other with an 
autodiscovered link. Subnetwork-2 contains two NEs, C and D, that are connected to each other 
with an autodiscovered link. There is also a manually routable link between NEs B and C. To 
create an SNC between NEs A and D, you must move NEs C and D into Subnetwork-1, or move 
NEs A and B into Subnetwork-2.  
Prime Optical includes a feature to automatically group NEs in subnetworks. This feature is 
enabled by default. If a routable link is created between two NEs in different subnetworks and 
Prime Optical merges the two subnetworks, the result is reflected in GateWay/CORBA. The two 
subnetworks are merged automatically when the Automatically Group NEs in Subnetworks 
feature is enabled in Prime Optical. 
2.2.4.2  SNCs 
SNCs are supported only for ONS 15310 CL, ONS 15310 MA SONET, ONS 15310 MA SDH, 
ONS 15327, ONS 15454 SONET, ONS 15454 SDH, ONS NCS2K SDH, ONS NCS2K SONET, 
ONS 15600 SONET, and ONS 15600 SDH NEs. Prime Optical does not support SNC in 
pending state. However, Prime Optical SNC has a proprietary deleting state. 
2.2.4.3  AVC Events 
In certain situations, Prime Optical cannot provide the list of changed object attributes. In this 
case, Prime Optical generates an AVC event with an empty attribute list. The NMS makes a get 
call to retrieve the object details.
