That's a good question. I was assuming you would use some sort of static/surge 
discharge device to ground, which could be a gas discharge tube,
an MOV or a variant of silicon avalanche diode(s).

You might also want one across each pair, but from what I have always been
told, you don't need them for twisted pairs. 

There was a discussion recently on sci.electronics.repair, about determining
what a missing component was. The first guess was an MOV, but in the end
it was thought to be a packaged silicon avalance device.

Did you check out the link I included in a previous post? If I had to guess
where to start I would have said polyphaser or transtector, now they are the
same company.
