1.5.3. Redundancy
NMS-4000 supports comprehensive redundancy in the Head-end system. Redundant
devices are used as a failsafe in case of primary device failure. Hot backup is automatically
implemented by the NMS-4000 without operator intervention. Figure 1-13 shows an example
of the redundancy process.

Malfunction
NMS-4000 does the following in case of a device failure:
1. Identify trigger (Urgent alarm, loss of comm.)
2. Search for lowest priority device
3. Switch Inputs and outputs
4. Update configuration
1.5.4. In-Bound Control
The NMS-4000 enables remote reconfiguring or downloading software to an individual
IRD/STB or to groups of IRDs/STBs. Both operations are done in band within the DVB
stream. The transmission can start from either an encoder or Mux. The DVB stream can be
sent over any media (Satellite, Cable, Telco, Etc). Downloading does not interrupt customer
service. Figure 1-14 shows a typical IRD remote control application set-up model.
