Hey Everyone,

Quick (and probably dumb) question.

Let's say I have (2) 3800 Cisco Routers on my desk with Serial T3 cards installed.  I want to verify that the cards are working and configured correctly before I send them out to their future locations.  Now, with Ethernet, I can just connect crossover cables and get the connection.  Can you do this with the Serial T3 cards?  I wasn't sure if you needed CSU/DSU's on each end or should I just be able to connect the Rx/Tx connections and have connectivity.  I've done that, I get link lights but I cannot ping from one card to another (there are no ACL's) nor can I ping the card directly from the router itself.  

Setting the cards to lookback local works and I can ping the cards within themselves, so I guess that is something.
