Board SS4 is an interface board for DUST protocols. Corresponding to the specific configuration, it is inserted in one of the three CS7 module slots. A maximum of three boards per carrier module can be inserted.

The interface board has two serial interfaces. The configured DUST protocol can run on one interface, and the second interface is used as service interface. The hex monitor runs on this interface in the background. Both interfaces are available at the 26-pin sub D socket connector X5.
