2.5 COMMUNICATION INTERFACES
The Base System provides one RS-449/X.21/V.35 communication interface. Additional interfaces can
be added as required, and as space in the chassis allows. The 6U chassis can house an additional 10
communication interfaces. The 3U chassis can house an additional 4 communication interfaces.
The communication interfaces are mounted from the rear of the chassis. The comms connectors are
located on the top half of the 6U chassis or on the right side of the 3U chassis. The remaining half of
the board can be equipped with a set of six inputs, solid state outputs or relay outputs.
