[PrathibaJee]

To support the default value for the attribute fc-blocks-signal-to-lp, need to include the typedefinition blockDirection. Please refer issue#18

Discussion on the 5G-xhaul call on 15th of December 2021:

• UML2YANG tool is having the neccessary code changes to include the type definition.
• We also generated a core-model and able to see the changes. The following entries will be available in the yang,

typedef block-direction {
    type identityref {
      base BLOCK_DIRECTION;
    }
    description
      "Provides the potential signal blocking modes.";
  }
identity BLOCK_DIRECTION {
    description
      "none";
  }

  identity BLOCK_DIRECTION_NO_BLOCK {
    base BLOCK_DIRECTION;
    description
      "The FC is not blocking signal related to the LTP.";
  }

  identity BLOCK_DIRECTION_INGRESS_BLOCK {
    base BLOCK_DIRECTION;
    description
      "The FC is blocking signal that is flowing into the LTP from the FC.";
  }

  identity BLOCK_DIRECTION_EGRESS_BLOCK {
    base BLOCK_DIRECTION;
    description
      "The FC is blocking signal flowing out of the LTP to the FC.";
  }

  identity BLOCK_DIRECTION_BIDIRECTIONAL_BLOCK {
    base BLOCK_DIRECTION;
    description
      "The FC is blocking both directions of traffic, i.e. Ingress and Egress, to/from the LTP.";
  }

This will be available if we publish a new release of the core-model-1-4
