1.5. Characteristics and Specifications
1.5.1. Receiver Input Specifications
The following tables summarize the features and specifications of the various receiver input
options available for the IRD-2600 and the IRD-2800 Integrated Receiver Decoder:
• QPSK input option, see Table 1-5
• DNSG input option, see Table 1-6
• QAM input option, see Table 1-7
• G.703 input option, see Table 1-8
The decoder is able to receive the following, PDH and SDH, ATM input interfaces as
specified in DVB standards; ETS 300813, for PDH and ETS 300814, for SDH.
The IRD also supports an option for 2 PDH Inputs with loop-trough of the selected input, with
automatic redundancy switching between inputs A & B. Time between switching is controlled.
The specifications of these ATM protocol supporting front-end interfaces are described in
Table 1-9 through Table 1-11.
