The 2611XM has 2 Ethernet ports, 2 WIC slots, and an NM slot.
You can put a WIC-2T in each WIC slot, that's four high-speed serial links. The NM slot can be filled with an NM-2W, providing 2 more WIC slots, and 2 extra WIC-2T in the WIC slots, for a total of 8 high speed serial ports.
You could also fill the NM slot with an NM-8A/S to provide 8 mid-speed serial ports. You could even fill it with an NM-32A to provide 32 low-speed asynchronous serial ports, these are mostly used to connect to console ports of other routers in the role of an access server. You could thus theoretically get a total of 32 low-speed and 4 high-speed is 36 serial ports on a single 1U 1600 series router.
I've ignored lower-density options like the NM-16A, the NM-4A/S, and the WIC-1T.
The Cisco 2611XM features ethernet connectivity, two ports, and a network data transfer rate of 100 megabits per second. As the product is older, there is less support for this system.
