The obvious is that you swap lines to get the cable out of the equation. Next, a digit analyzer will tell you what the length of the flash time is in all trunks and you can compare that reading to an SLT. I have a pair of spare Ziad's on the shelf that I might be persuaded to part with for about $80 each if you don't own one.
