LAN connector (as in Visio)

[GiooiG]

I'm trying to figure out which shape to use to represent a LAN. The minimum I'd need is a line from which other perpendicular lines stem out. Needless to say. I thought also of a line with connectors, so that I can attach external lines to it.

Is already there such a shape? Can I, and how, create it?

Thanks, Gio
