This type of radio system uses these types of control channels if the System is "roaming", or has a "home base", or has a "collective" base. Thus the packets that are usually heard in each frame.
Since the LTR standalone doesn't use a control channel, it only uses the "blip" of data, like somebody keyed on and off the radio to let the system know its there. But, with Passport, this control channel is required because of the three roaming, home, or collective bases.
