I picked up two Cisco 2610 routers to start practicing my CCNP. Instead of going with the DB60 serial cards and cables I went with the WIC-1DSU-T1 interface cards. I need to connect both these interfaces together to act as a serial interface for the labs.
Now I think I figured out the cable problem. I made a T1 crossover and the CD LED is now green on both interfaces. The only problem I have now is that both the interface and line protocol are down, even with the no shutdown command entered.
Please help, thanks!
