3 RAN
This section describes the various controls and indicators for RAN specific modules.
3.1 RDC
The RAN Down Converter (RDC) takes RF signals from a primary and secondary antenna and
down converts the signals into IF. Signals are input into the card over coax cable terminated
with SMA connectors on to the front panel of the module.
The front panel indicators for the RAN Down Converter are:
• FLT LED – Red LED lighted when module has failed or upon startup until the
module has been initialized. This light will blink after the module receives a system
clock and is awaiting initialization
• PWR LED – Green LED lighted when module has power
