I also found that my co-lo space provider would not allow GSM antennae 
near the data server cabinets, so either having long co-ax leads or boxes 
on the end of rs232 leads was a neccessity. (This was a SMS application 
rather than voice, but you get the drift!)

I'm sure there isn't an issue, but they were just being paranoid when the 
racks were full of many other clients equipment...
