RADIO
CONFIGURATIONS
When connecting an OEM M1-3 multiplexer to a
Constellation 3xDS3 or 4xDS3 radio, DS3 errors might
be observed for shorter cable lengths. This can be
caused by reflections in the cable connecting the
equipment. Installing a 3dB attenuator in series with
the DS3 cable when the length is less than 10 feet may
be required. For additional information go to the Harris
MCD Premier website at
