//Description:
//      This file contains the primitives passed from DSS1
//      Coordprotocol to LAPD protocol.  They include only
//      two primitives, namely lapdDATAreq and lapdESTABLISHreq.
//      These two primitives are called from the Coordprotocol,
//      and the LAPD protocol must implement the lapdDownInputs
//      primitives in its state machine.
