How to connect 2 serial interfaces?

Question

Hi, I have s0 (192.168.0.2 ) on R2505 and s0/0 (192.168.0.1 ) on R2610 and one DTE/DCE cable and I want to connect these 2 serial interfaces. I pluged in DTE on s0 and DCE on s0/0. I set up clockrate 56000 on s0/0. I tried to ping s0 from s0/0 but it doesn't work.

Where I made a mistake?

Why not post the configs? Electrons are cheap.Also state the exact model of the 2610 serial card.no shutdown?Bad netmasks?  255.255.255.252 is the convention here.

Thank you, Ivo.I did everthing you wrote but I still have a problem. When I accesseach router via their corresponding console they work well, but at themoment I connect routers with DTE-DCE cable, router R2505 gets stuckand do not respond to any typing on my keyboard while R2610 respond totyping. What could be the problem? Hardware or software?Ivo Mangiavacchi wrote:

Hardware, I think.But as last resource upgrade the IOS, just to be sure.Try also swapping the used interface on the 2505 from ser0 to ser1.--Ivo

Thanks for suggestions.I swapped from s0 to s1 but the same thing, R2505 gets stuck. I amusing an brandnew DTE/DCE cable. Is it possible that this cable is notcompatible with s0 and s1 interfaces on R2505, as R2505 is an oldrouter? Why R2610 never gets stuck, only R2505 getting stuck? I didn'ttry upgrading of IOS on R2505. Is it possible to do with only 4 MB  ofmemory for IOS? Now I'm running version 11.1(15) of IOS.Ivo Mangiavacchi wrote:
