Need recommendations on a terminal server setup

Alright, I'm getting ready to make my 11/23+ available online for people to play with, but I'm a bit stumped as far as how I should attach the serial lines to my Ethernet network. Now, I have a Sun server running Solaris 10 which I was able to connect a couple serial lines to and then tunneled that through a telnet port, but I'd rather not do that...with the setup I'm thinking of, we're talking about a whole lot of cable running into that box. Does anyone here have suggestions on what I should use for a terminal server? If I could just mount a DECserver box in my PDP-11 chassis that would be great, but isn't the Ethernet port DECnet-only? I don't know what I'm doing when it comes to this, so feel free to correct me. As always, any help is appreciated Julian
