10,003 PROP_STS12c_and_VC4_4c 

Obsolete 

In v3.0, a layerRate equivalent to 
PROP_STS12c_and_VC4_4c has been 
defined, i.e., LR_STS12c_and_VC4_4c. So, 
PROP_STS12c_and_VC4_4c will no longer be 
used.  

 

 

The following table indicates the EMS support of SNC Type transitions that can be invoked 
through the modifySNC() operation. Although the EMS can provide support for transitions among 
all SNC Types, the MTNM interface only defines the transitions between ST_SIMPLE and 
ST_ADD_DROP_A or ST_ADD_DROP_Z to be mandatory, when modifySNC() is supported. 
Note that ST_ADD_DROP_Z bi-directional is new for Phase 3. 

The modification of the SNC’s Static Protection Level does not impact the SNC type. The EMS 
may support the modification of an unprotected SNC to being a partially, fully or highly protected 
SNC while maintaining the same SNC type. 

In order to complete the following table, the EMS supplier should do the following: 

1.  Indicate the supported transitions by placing the word “supported” in the appropriate cells 

(this should, at least, include the mandatory transitions). The other cells should be blank.  

2.  For each supported transition, indicate the GOI.  

3.  For ST_EXPLICIT to ST_EXPLICIT or other SNC type to/from ST_EXPLICIT, the GOI 

needs to be described for different ST_EXPLCIT traffic flows (e.g. for ST_EXPLICIT to 
ST_SIMPLE the SNC modification is supported as Hitless whenever only inactive 
protection legs are removed).
