We don't actually use that term here.
If an officer is working a case and has suspect information (or a description of a missing person, etc.) then (s)he can have dispatch relay that information to surrounding municipalities on the radio. We can further fax/email dispatch information for teletypes to all local/state agencies if appropriate. An officer can do this on his or her own authority.
