*
* Purpose: This code-file defines the SUA adaptation functions used by
* the SUA application for:
* - initialising the SUA layer
* - reading the SUA configuration file
* - registering a local SUA instance
* - Setting up the association with a remote SUA node
* - terminate a association
* - get SUA path info on a certain (SUA) association
* - get SUA destination pointcode (IP and SS7) and status
* - get SUA origination pointcode (IP and SS7)
* - deactivate a SUA association
