It is possible to modify the gateway installation to support forwards to multiple destinations. Follow the steps below to add an additional forward destination AE title to your OnePacs Gateway deployment:

• First, install the OnePacs Gateway and reboot. Note: This method has only been tested on version 1.9.15 of the OnePacs Gateway. Please upgrade before attempting this modification.
• Log in to the OnePacs Gateway administrative interface.
• On the AE Management tab, create a new AE title definition for the additional forward destination. At a minimum you will need to enter the AE Title, HostName, and Port of your destination. You may press the echo button to ensure that the device is properly setup.
• Press the create button.

• Second, Log into JMX console

Select the service=Forward To add a simple forward for all studies add the new destination AE Title as part of a comma separated list in the Forwarding Rules configuration.

If you need more power to determine how studies are forwarded you could also configure the service=Forward2 which uses XSL to forward studies based on DICOM attributes.

it

the

Go

into

that

folder

and

create

a

file

called

forward.xsl.

This

the

Title.

*Note that if you are using the forward2 service in this manner, you need to also delete the destinations listed in the "ForwardingRules" configuration shown above; otherwise, studies will be forwarded both according to the forward service and the forward2 service.

Edit the file to forward the to the correct destination AE title. There are several example forward.xsl files that already exist in your installation under the C:/onepacs/gateway/server/default/conf/dcm4chee-ae/MOD_AET directory and may be used as examples. Below is an example of a forward that will forward everything from a device with the calling AE title of CALLING_AE1 to DESTINATION_AE1 and will only forward studies that have DICOM institution name (0008,0080) of INSTITUTION_NAME to AE title DESTINATION_AE2. (Both destinations would have been added before when adding the AE titles)

Change the configDirectory variable in Forward2 service to be /conf/forward-ae and apply changes.
