Among my older clients they've always understood it when analogised to a 
dog whistle - dogs can hear it, humans can't; modems can hear the 
broadband, voice users can't. But because 'computers talk that much 
faster', the quality of line needs to be that much higher. ELI5 but I 
don't like to fix that which isn't broke.

I'm pretty sure there's still that thing going on where the bell-heads 
say any problem must be the net-heads fault. Only limited success 
telling clients they MUST NOT (rfc2119) mention the broadband problem 
when they report the voice 'problem'.

I've also seen many broadband problems mysteriously correct after the 
online tests have found "no problems detected" making me think that's 
probably tosh.
