The 2522 has 2 regular high speed serial ports and 8 low speed serial ports. The low speed serials support speeds up to 115200. If you're just going to use it as a frame switch I would recommend the 2523 which is the same as a 2522 except that it has a token-ring interface as opposed to an ethernet interface. Also the 2523 will cost about 1/3 less than a 2522. Brian Dennis, CCIE #2210 (R&S)(ISP/Dial) CCSI #98640 5G Networks, Inc.

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!
