It’s been a while since the Barn was cleared out and it’s a good chance to get rid of old cabling from the  days when all you had to connect people to were telephones. 

The Cat 5 replaced copper for phones and desktops and now even that is partially redundant,  With voice over IP, only one connection is needed for voice and data. 

Not even that if your wireless is good enough.  The cable-free office might actually be here sooner than we think.
