//Description:
//      Implements the network interface between MTP3 and bisup.
//      Network interface protocol, coordinates messages between
//      different BISUP-instances (using SIDs) and MTP3-protocol.
//      Has pducoders as static datamembers, to be used for coding
//      received frames into sigPrimitives which will be sent to the
//      correct bisup instance.
