A statistical multiplexer includes a plurality of primary encodersand at least one backup encoderwhich is activated a primary encoder fails. The statistical multiplexer also includes at least two multiplexerssuch that at any given time one of the multiplexersis in an active state and the other is in a backup state. The encoders, the multiplexers, and a rate processoremploy a dynamic identity allocation arrangement for identifying a source of the messages such that messages originating from the encodersindicate whether the source is a primaryor backup encoderand messages originating from the multiplexersinclude a character selected from among a predetermined sequence of characters that is incremented to the next character in the sequence each time one of the multiplexerstransitions between an active and a backup state.
