The following table describes the inbound channel components.

Component	Sub-component	Description
Inlet	HL7 listener	Listens for incoming messages on the provided IP address and port number. Converts the message into XML format and sends back ACK or NACK, based on the message validation status.
Route	Move agent	Pre-existing service to move the input document to the outlet.
Outlet	File emitter	Writes the XML-based HL7 message into a file under preconfigured folder.

The following table describes the outbound channel components.

Component	Sub-component	Description
Inlet	File listener	Reads an XML-based message from a file that is placed in the preconfigured folder.
Route	HL7 adapter target	The HL7 Adapter target is added to a new Process. This process is added to the Route. HL7 Adapter target converts the XML based message into HL7 format and sends it out on the preconfigured IP and port number.
Outlet	Default.outlet	Writes the Acknowledgment message received against the sent HL7.

To execute an inbound and outbound process in iWay Service Manager:

1. In the left console pane of the Registry menu, select Channels.
2. Mark the appropriate channels and click Build.
3. From the iWay Service Manager Console, click Deployments and select the Deploy button.

   A list of available deployment channels is displayed.

4. Select the inbound and outbound channels previously created, and ensure that both channels are running and active.

   

5. Send a sample HL7 Version 2.5 message over MLLP to the port number 10025.

   Note the Acknowledgment message received. The HL7 message will then be available in XML format under the preconfigured target folder.

6. Validate the XML file by checking if all elements are populated.

   The inbound channel has now been executed.

7. Copy the XML file generated during the above process into the configured incoming file folder.

   Ensure that an outbound HL7 message is received on port 22025. Note the Acknowledgment message saved in the destination folder configured in the file listener Outbound channel has now been executed.

The following steps confirms the legitimate validation and processing of HL7 messages by the Inbound and Outbound channels:

• Comparing the test valid HL7 message sent to the Inbound Channel against the HL7 message received from the Outbound Channel should show no data loss.
• Sending an invalid HL7 message to the Inbound Channel should result in a NACK being returned describing the problem with the HL7 message.
• Placing an invalid XML file in the source folder path for the Outbound Channel should not send an HL7 message over to the receiver, and instead should be blocked within the Outbound Channel.
