A.1.5.5 Additional MA-309C Input/Output Options

In the situation where the VF-25 module and MA-309C module adapter are used for transport of 2-
Wire Audio with E&M signaling on the output side of the circuit, there are two possibilities to adjust the
output signal level (one on the VF-25 module and one on the module adapter). Table A-17 shows the
selectable attenuation control for nominal input levels of -16 and 0 dBm from voice frequency modules
using the MA-309C module adapter. Table A-18 lists specifications for this adapter.
