The Cisco 3640 makes for a nice console server to hook up to your
out of band network. It supports a 32port Async module as well as
10/100 ethernet and T1 WIC (supports Frame Relay, of course). It also
supports E1 for your non-domestic sites.

It's always good to have a backup, even for your management netowrk. When
the Frame Relay network fails, there's always the OOB modem/POTS.
