Slow Response Time for Tractor Point
6 meg wireless connection, sometimes slow, but most times normal as any other site, could be the number of users at one time posting or looking that can slow it down, it is a Forum board after all, servers do need to seek and search for each request.

Slow Response Time for Tractor Point
kyvette, your close, but not on target. 28 T1's ride on a T3 or what the carriers call an DS-3, not an OC-1. The common method of transporting a DS3 is over an OC-3, which is the smallest termination device they make. The next up would be an OC-12 which carries 12 DS-3's or split off into 6 DS-3's and 6 T1 breakout boxes, or 9 DS-3's and 3 T1 breakout boxes, or whats commonly referred to as Dmarks. The speed of a DS-3 is 44 Mbs, the speed you are referring to and the Sonet are the interoffice backbones of the carriers. In most situations with ISP's and T1 customers, what happens is the ISP orders a DS3 with the local telco, and that terminates from the closest CO to where they terminate the DS3. From there the ISP orders a DS1 to the customer and the telco will Mux the T1 onto the T3 at the ISP, from the CO it goes through the Telcos backbone, either over sonet, ds3, or in some cases directly onto copper. From the last Co to the customer, depending on distance, it leaves the CO and runs on copper. Rarely does it hit the customers prem with fiber, in those cases there is a lightspan that is located outside the customers location within the last mile and terminates over copper at that point. T1's are based on copper, T3s are based on fiber.
Now for cable systems, they can get as high as 10 meg downstream, but it is a shared system, meaning the more poeple downloading, the slower the connection will get, upstream is fixed at those speeds you posted. Cable systems use frequencies to transmit the internet data that ride along with the analog signals of the video stream, in most cases now, all the signals are moving to digital, so more bandwidth will be avaiable which will ease up the constraints of a shared system. The speeds which some people have seen who use cable are probably experiencing the shared bandwidth syndrome of too many users, since all shared service, whether its, dialup, cable, satalite, or wireless, always oversubscribe users on these systems, usually on a 4:1 ratio. Only those with a fixed T1 or T3 have full unshared bandwidth.
FYI, worked as a network engineer for an ISP for 7 years, and in fact gave a few SBC techs a lesson or two in T1 technology. 
Hope I didnt cause more confusion, and helped some to better understand how broadband works.

Your good for the most part, except I think the overhead part you are thinking of is related to the voice portion from the early days when each channel needed a seperate carrier of 8kb for the encoding, but these days, most DS1's are Muxed onto DS3's and the "overhead" has been relegated to the actual devices that do the Multiplexing. As for the T1 cabling, it can run point to point over copper for many miles, in fact it can run from one location to another that is 50 miles away if needed. The limitation depending on what type of T1 is being installed, be it HDSL2, HDSL4, etc, the # being the type of wire it runs on. Lets take HDSL4, it runs over 2 pair of copper, with a limitation of 5000 feet, in between these limitations of the run there are what are called doublers or repeaters that boost the signal much in the same way a switch or hub does on an ethernet run. So on a full copper run of say 15,000 feet, there will be 2 pair of copper and 3 repeaters/doublers. One pair is the transmit tip and ring, the other is the recieve tip and ring. A T1 is a fully synchronis circuit, it can send and recieve at 1.54Mbps for a full duplex speed of ~3mbps. An HDSL2 runs over 1 pair of copper, and is also full duplex, it has a transmit and a receive wire, bit no tip and ring, instead its a fully digital signal that is encoded and decoded from the SmartJack to the first CO, or LightSpan. When working with SBC, I found they prefer the 4 wire over the 2 wire because if there are any issues with the copper the 2 wire tends to fail.
Here is a link for a more detailed write up on T1's.

Here is an ultimate link specifying what does what.
Kyvette, I think I see what you were saying, but I think you got the two confused. An OC1 is SONET, T1's are muxed onto SONET, but they are used for the Telcos backbone, so they can run many channels over a single strand of fiber easily, the overhead you are referring to is the clocking and VTs needed for DS1's to run over SONET. The majority of the overhead is from muxing the DS3 onto the OC1. In most cases though the end receiver, the ISP or customer runs the Mux off a DS3, not the SONET, only the Telcos do anything with the SONET, except in the rare cases of a major customer such as AOL, or maybe Motorola. In those cases they would purchase fiber from a carrier, called Dark Fiber and implement their own equipment.
Note: I edited the information after doing some further researh into SONET, I found there are other uses other than for the main backbone.

Sounds like fun . I have 7 years of internet experience, and now work on a different part of internet, VOIP. Today I go for my CCNA, so wish me luck!
A CCNA with a tractor, a dangerous combination, mowing at the speed of broadband!

To Bvance, most of what was said, directly relates to this thread you started. Speed on the internet directly relates to the speed one can pull down a website, You may have a high speed pipe running from your home, but the upstream your provider has could get clogged, therefore some sites like this one can show performance issues that not everyone can see, hence the discussion of T1's and others. I know everyone has seen cable internet commercials and how they brag about outperforming dialup and DSL, and most people fall for it and wonder why sites become slow. So in closing, there is a 99% chance that nothing at all was wrong with this site, and instead you experienced a network bottleneck somewhere between the server this site resides on and your PC where you were viewing it.

I know I did, I thought I knew it all about SONET, but since I had questioned it, I went and looked it up, and now I know more about SONET than I need to.

The Geeks shall inherit the earth. And yes working on, around, and with the tractors are so much simpilar.
