Universal Fail-Safe Block Interface (UFSBI) is a fail-safe multiplexer capable of transferring 16+16 i.e. a total of 32 On-Off relay states
between location physically separated by a distance but connected through a voice/data channel over OFC/Microwave or Quad cable. The
UFSBI can be effectively used to replace the signalling cables required for repeating relays between mid-sec block huts and end stations.
