channel1 is a Webservice interface for the reporting of incident data.
An example WSDL of the interface can be obtained via the Public Naggregator Service instance (WSDL link). If you build Naggregator manually, you will find the WSDL in the project/ticket/webservice/channel1-VERSION.jar at META-INF/wsdl/Channel1Service.wsdl.
A documentation of the interface itself can be found in the JavaDocs (the interface itself is here).
The Samples & Snippets package contains a sample called Incident Roundtrip that illustrates the use of channel1 and channel2.
