Hi All - I am looking for some routers to setup my CCNP lab. The Cisco 2522 seems to be a great for Frame Relay switch if I can use crossover cable with the A/S serial ports. However, I am not sure if the A/S will be acting exactly the same as the synchronous serial port? Can I connect these asynchromous serial port to a synchronous serial port on a 2501 router using crossover cable? Thanks all in advance!
