Synopsis 

Description 
This interface enables an NMS to create a Y-cable topological link manually between two managed 
elements. A Y-cable link is a bidirectional link with one PTP source and two PTP destinations. Because 
of the limitation in TMF for topological links that have one PTP source and one PTP destination, Prime 
Optical reports two topological links for a Y-cable link. These two topological links have the same 
nativeEMSName. See 

 for the naming convention for the Y-cable topological 

link object name. The destination of the Y-cable link must be on a DWDM card on an ONS 15454 
SONET/SDH or ONS NCS2K SONET/SDH. 
Prime Optical generates two object creation event notifications when a new Y-cable topological link is 
created. 
The topological link returned by this method is one leg of the Y-cable.  
Parameters 

createData 

topologicalLink:MTLCreateData_T  In 

Data structure containing details for 
creating a new Y-cable topological link. 

topologicalLink  topologicalLink::TopologicalLink_T  Out 

One leg of the created Y-cable 
topological link information. 

 
Prime Optical support for MTLCreateData_T structure is as follows: 

•  string userLabel 

-  Supported. The value of this field is assigned to the nativeEMSName of the newly created 

topological link. 

•  boolean forceUniqueness 

–  Prime Optical guarantees the uniqueness of topological link names. 

•  string owner 

–  Not supported. 

•  globaldefs::ConnectionDirection_T direction 

–  Supports only CD_BI for bidirectional links. 

•  transmissionParameters::LayerRate_T rate. Supported layer rates are: 

–  LR_Physical_2_5_Gigabit_ITU 
–  LR_Physical_10_Gigabit_ITU 
–  LR_DSR_OC3_STM1 
–  LR_DSR_OC12_STM4
