I just bought 3 x 2610 routers for a lab. Each of the above has a T1 DSU/CSU and an Ethernet card.
I gave the s0/0 int an IP and subnet mask yet not able to ping the int from the router. Any advise would be appreciated.

Check out the following pre-requisite as your serial interface is howing down !!
Interface Serial0/0 (down/down)
WARNING: This interface is down.
This is related to hardware issue or physical connection failure.
TRY THIS: Follow the following procedure.
1. Make sure that you have connected serial cable from router interface to CSU/DSU
and RJ45 straight cable from CSU/DSU to service provider's wall jack or patch
2. Check the LEDs on the CSU/DSU to see whether the Carrier Detect (CD) is active.
If not, confirm with the service provider that the link is active by giving
a loop test.
3. If the link is still down, try with another serial interface. If the link comes
up now, it indicates that the previous interface was faulty.
4. If the link is still down, try running a loop test from the CSU/DSU towards
the router. Once it is in loop, issue a 'show int serial' command, and verify
that the interface status is UP/UP (looped) now.
5. Now try and ping your own interface. If you are not able to see the status
as 'UP/UP (Looped)' and not able to ping your own interface, this might indicate
a hardware problem.
Note: As this interface is down, the counter values analyzed by Output Interpreter
might not reflect the current condition.
