said by SimbaSeven:3. Actually upgrade your towers to OC3 instead of adding a T1 here and there.
the majority of carrier activity is bypassing TDM and going to Ethernet handoffs
at any rate, they have already for some time now been actively implementing much larger bandwidth adds than you suggest...an OC3 would only get them a bit less than 150Mbs max....from what I have seen from all the carriers, they are running more like 600-700Mbs per tower and trending has the industry expecting demand for 1G connections being the norm within the next 18months
I have spoken with numerous service providers who are looking for upgrade paths to take their current 1G service rings and spurs to 10G to facilitate this growing demand from cell providers at their towers.
