means for connecting the respective outputs to at least one
communication element,
means for providing first input signals, corresponding to at least a first
channel in a first portion of a frequency band, to the input of a first of said
transmitters,
means for providing second input signals, corresponding to at least a
second channel in a second portion of said frequency band not including
said first portion, to the input of the second of said transmitters,
means for sensing a loss of output signals from one of said
