In past jobs, we have done this for both administration and some
monitoring.
For administration, we just used an old Annex3 terminal server as a
serial connection mux. We plugged up to 64 serial cables into the
consoles of various devices, and connected a modem to one of
those serial cables. That worked really well.
For monitoring, a team that I worked with had a machine that monitored
the network and had a connection to a phone line to issue pages when
things broke.
I think these are both fairly common setups.
Hope this helps,
