Correct, there are no cards inside any system. You have an external box that
can have a combination of PRI, FXO and FXS ports; depending on need. The
external box is connected via USB to the two systems. The twinstar option
allows you to connect the external box to two systems via USB and provides fall
over from primary to secondary on failure of the primary.
