Overview: Inbound HL7 ADT Data module
ADT information is transferred to the WACS server in this sequence:
1. WACS initiates a connection to a facility’s CIS on a preconfigured TCP port (usually in
the range of 5600-5700).
2. Once a session is established, WACS listens for and accepts particular ADT message
types from the CIS.
3. WACS updates and stores the data on a local SQL database.
