4 Interface specification
4.1 SDH common information model
The SDH common management interface shall meet those specified in Technical specification for SDH transport network management - Part 6: EMS-NMS interface information model based on IDL/IIOP.
4.2 Description of termination point
MSTP termination point, the termination points include ATM termination point, Ethernet termination point and data structures (not defined separately), the definition of terminationPoint::TerminationPoint in Technical specification for SDH transport network management - Part 6: EMS-NMS interface information model based on IDL/IIOP is used. The characteristics of MSTP termination point will be further described in this part.
To support the unique parameters of MSTP termination points, it is necessary to add a definition in the transmissionParams of TerminationPoint. For example: {layered=“LR_Fragment”, name=“lcasEnable”, value=“true”/“false”}, the setting of LCAS enabling is achieved through a universal interface for modifying parameters at termination point.

LR_Fragment lcasEnable true
false SC LCAS enable
