Service Provider Profile (SPP) into the Ensemble-Multiplexer.Ø All necessary information about the number of possible Streams, FIG Files,

max. Data Rate etc. is in the SPP.

Ø The Service Provider can only operate within the limits of this configuration.Ø After connection set up the SPP will be exchanged between Service

Multiplexer and Ensemble Multiplexer.Ø To be able to set up a connection the Service Provider must have the

following information available:– Ensemble Multiplexer ID– Service Provider ID– Time slots to be used

recommended.l A central element of a redundant system is the 2-Mbit/s
