So I got my 2610s, and I got 1 WIC-2T right now, I bought some crossover DB60 to smart serial connector. The DB60 ends are going to my 2501's.
I have tried countless configurations to get these links up, changing the DCE side and so forth, and they wont come up. I found a command on the 2610 S0/X interfaces called physical-layer sync. I applied that command and the smart serial ends came up in loopback, int up, line prot down. The 2501's show no connection at all.
ANything special I need to do since the WIC is Asynch/synch and I just need it to be synch? Im not sure if I have a bad WIC or bad cables (both?) otherwise, I am leaning towards the WIC as the idiot I bought the wic from on ebay has never heard of static bag, and shipped it UPS (United package smashers

).
I hope not, if so these will be the second time I got burned on ebay this month, I bought a 2924 EN and it came DOA, but at least the seller is working with me for a refund.
