What was the defense point in bringing up the size of the router required to operate with an FXO port?
It was rebuttal to the prosecutions assertion that the FXO card could fit in a pocket. The Cisco expert testified that a router was also required. Yet the prosecutor kept going on and on about how small the card was. So the defense physically showed the size of a router that the prosecution witness said would be required to run an fxo card. That was the point of it. The prosecution mislead the jury by suggesting the evidence could fit in his pocket.
