Using simulink: why have the digital passband blocks disappeared?

Hi, I am a student currently using simulink, and I would like to ask you something: why have the digital passband blocks disappeared? How can I then modulate with several channels in different frequencies? Thank you very much for your help!

Can you please say specifically which blocks you are referring to? Are you sure these blocks are part of core Simulink and not part of a toolbox that you do not have installed? Communications System Toolbox or DSP System Toolbox for example.
