Description: This group contains parameters in route request data that govern the route selection. Values of these parameters are obtained either from an operator or from the last route request message from a PORS VC that contained such parameters or a reference to such parameters (parameter profile reference) as part of the route request data. Route request messages from a PORS VC that ask for a manual route do not contain such parameters or reference to such parameters. All other route request messages either explicitly contain route request data parameters or a reference to a profile containing such parameters.

This group of attributes is therefore not applicable to manual routes.
