French to English Social Sciences Media / Multimedia Dealing with the media

The document I am translating deals with a drill to test the coordination and efficiency of the various actions planned to deal with a nuclear emergency.

One of the sections deals specifically with communication.
The simulation exercise has a number of objectives, such as testing the organisation of the communication services of the various bodies, testing their responsiveness, and testing the coordination between them.
For the latter point, examples are given: "partage de l'information et calage des médias".

I understand that the various bodies involved in dealing with the emergency need to share information and "sing from the same hymn sheet". Is that is what is meant by "calage des médias"? Any suggestions for translation?

Thanks for all useful input!
