Hi all,
I purchased a 2621 the other day and it came with an Adtran TSU ACE Gen 2. Forgive my n00bness, but I'm not really sure what it is. I know it connected to the router via serial (which is nice because I got the 2621 for $21 and it came with a WIC-2T

), but I'm wondering if it would be of any value in my lab (T1 sim, maybe? Could also do that with a T1 crossover cable, I suppose) or if I should just try to get $10 or $20 back out of it.
Thanks!
Brandon
