Can anyone tell me exactly what the mysterious ‘filter’ is that this device possesses?
And which the -B10D does not possess, is that correct?
Is this a good thing?
Which other ZyXEL devices have modems that are the same quality?
Are there any that are better?
I saw a picture of the PCB but I have lost the url for it. I could not identify the magical filter device as a separate chip on the board because Indid not know what I was looking for. Is it even a discrete device as opposed to something just integrated into some large chip. could anyone set me straight?
