Hi all, hope someone can give some advice on this.

I have a VG224 located at the 5th storey of a building, in our server room. If I have fax devices located on every floor till 20th storey, what is the best way to connect them up?

I understand the connection has to go through the building riser. But what connection should I use? Copper wires? Category 3, 4 or 5 cables?

Is there any references that you could recommend?

Thanks so much!

Eugene
