| backhaul upgrades I'm not sure where you guys are at, but I know at least in Chicago they're running fiber straight to the tower. I stopped and talked to the 2 guys doing it. Again, not an overnight process, but they are doing something.
By no means is this meant to be taken as a defense for AT&T, I don't like them at all. Just stating facts. |

Tell them to get their asses on a plane and head down to Austin. I'm dropping calls more now than I ever have in my 2 years with AT&T.

Switching services isn't always as easy as it would appear... |

True, but every cell contract has a 2 week to 1 month window to quit the contract without paying an ETF. If I switched carriers and the new service was not working I'd have bolted before being subject to an ETF.

ATT is running fiber to the tower but they are doing (at least in the mid atlantic area) unprotected, unmonitored, ehternet based fiber services. e.g 2 fibers from a switch at the tower to a telco company router and then into telco company transport. VZW is running ehternet over sonet to all their towers and hauling it all the way back as sonet to their pop sites. The advantages to the VZW approach is dedicated, monitored, redundant, near latency free bandwidth from every tower back to VZW's core network. VZW's approach cost substantially more but will be much more robust and reliable over time. Some of VZW's pop sites the towers are comming back to teh new Fujitsu FW9500's -- these muxes can switch upto 480 gigs per second. For anyone that cares here is a link to a data sheet on the mux:

| Only redundant if they are placing 2 fiber cables to each cell site which I for one don't believe they are doing. One cut cable and the entire cell site is down. We have several cell sites with OC-12's placed at the site but it is on a single fiber cable to the site.

All depends if they are the local ILEC or not. Most of the ones that I am familiar with are being provisioned on the Flashwave platform. |

It is still redundant-- we fix many simplex troubles where only one or two fibers in the cable are damaged e.g. rodents, gun fire, freeze breaks, sleeve corrosion, deterioration of the cladding... Very often it is a single cable to the site but the route the fibers take once leave the cable feeding the sight is diverse.
Two fiber cables to a site is considered a diverse feed site.
The redundancy also extends beyond the cable, the sonet based stuff has redundant optics, timing, data bases, rectifiers and on some services low speed ports. All of this redundancy is carried out through the sonet network.
Nothing on the fiber/ethernet is redundant. |
