2.5. System Expansion
This section provides instructions for system expansion through inter-connection of multiple
IRD-2600 and IRD-2800 Integrated Receiver Decoder units by daisy chaining the units.. It is
assumed that all IRD units are configured and operational.
The IRD supports two Loopthrough methods:
• Cascade Loopthrough Output from the Receiver Input (see paragraph 2.5.1).
• ASI Interface Loopthrough (see paragraph 2.5.2).
2.5.1. Cascade Loopthrough Output
Connect the input signal to the first IRD receiver input. Cascade remaining units as shown in
Figure 2-4 or for G.703 as shown in Figure 2-5.
