1.4.2What the Decoder Does
The G.703, ASI or IP interface is used to present the Transport Stream in the format required by the internal Decoder circuitry. At this point, the operation of the unit is the same as the Satellite Receiver.
The Decoder can be used to receive an input signal from a Public Telecom Network via a Network Adapter Unit (NAU) or directly via G.703. No error correction is supported at the input of the unit so a level of Quality of Service should be negotiated with the Telecom Network Provider.
