1.9.7 BITS Cable Installation

The BITS cables attach to the MICs using twisted-pair cables terminated with an RJ-45 connector on the
end that plugs into the BITS port. The other end of the cable plugs into the BITS clock. Terminate this
end of the cable according to local site practice.
Each MIC has one BITS input and one BITS output. The BITS inputs and outputs have corresponding
pins on the RJ-45 BITS ports. The BITS 1 inputs and outputs are on MIC A and the BITS 2 inputs and
outputs are on MIC B. See
ONS 15327.
