Re: I am with the Consumer Advocates

Well, there is no set formula for over-provisioning. but the trunks to the central office are pretty standard. A DS1 is 24 voice channels, a DS3 is 28xDS1, beyond that is fiber using OC3, OC12, OC48, OC192, DWDM. The fiber standards aren't used to carry traditional 64Kb/s voice channels, instead they are usually used to carry ToA traffic which has your voice call on a data network. Those speeds go upto 100Gb/s using DWDM.

Most telcos have their own ratio of subscribers to availible trunk lines. I believe Embarq uses 4:1 in most cases but not positive about that.
