Functional Description

A block diagram of the CDM-710G is shown in Figure 1-2.
The CDM-710G is constructed as a 1RU-high rack-mounting chassis, which can be freestanding if
desired. Rack handles at the front facilitate removal from and placement into a rack.
The CDM-710G performs several key functions:
•
It accepts incoming data from the terrestrial interface and converts it into appropriate
clock and data signals.
•
The modulator operates on the data to frame and encode it for transmission.
•
Encoded information is mapped for modulation.
•
A modulated carrier is transmitted from the IF interface for use by uplink equipment for
delivery to the satellite.
•
A carrier received from the satellite link is acquired and demodulated to recover symbols
and timing.
•
Error correction and deframing are performed.
•
User data is delivered to the to the data interface.
