If they are using copper DS1's, why not just upgrade to DS3?
In 99% of cases, the same exact copper pair used to deliver a DS1 can also deliver a DS3. The only real difference is the equipment on the end of it. If a cell tower today is served by a T1 there is absolutely no reason the existing infrastructure cant immediately be upgraded to a 45Mbps connection with very little downtime. -- Весна прибыла
