An optional Power Failure Transfer Unit (DPFT) can be installed that automatically connects

standard telephones when the system is in service. When power is restored, each telephone is
independently reconnected to system standard telephone circuit ports after it is finished with
its direct Exchange line call. The DPFT is normally installed on the MDF.
