Sample coding for a switched major node for a switched subarea

The following coding is an example of definition statements for a switched major node for switched subarea connections.

The IDNUM operands associated with both ends of a specific switched link must match for the connection to be established. If there are multiple switched links between two subarea nodes, the IDNUM associated with each link between the subarea nodes must be different for each link. Additionally, the combinations of IDNUM, NETID, and SUBAREA must be unique.
