The HL7 Gateway is an optional adaptor that helps external systems connect to PHC Hub. It is installed on the sender system (remote from PHC Hub). It is not required to initiate a real-time interface, but it does enable systems that currently save data to local files or that use MLLP (HL7 Minimum Lower Level Protocol (TCP/IP)) to send data in a real-time fashion using the required HTTP-based transport protocol.
When installed on a sending system, the HL7 Gateway listens for an incoming HL7 message and immediately forwards it to the PHC Hub inbound interface servlet using the HTTP-based protocol. After processing the message, PHC Hub responds with an acknowledgement message which the Gateway forwards back to the originating system over the original connection. If the Gateway encounters an error in this process, it immediately returns a negative acknowledgement (NAK) back to the originating system.
For more information, see the documentation distributed with the HL7 Gateway software.
