"No, real men with huge e-penises use OC256, about $More-than-you'll-ever-make a month."
OC192 you mean, which is roughly 10gb/sec. Of course, REAL men only use DWDM to stack 24 OC192's on a single fiber pair. (I'll admit a certain sadistic glee in pulling the fiber amp for maintenance work, and knowing that I just made 600,000 people scream at the same moment)
The optical networking stuff is surprisingly simple compared to the routers it connects to. A single Cisco 15454 would supply enough bandwidth to make all four GSR 12416's work up a sweat, and I was only pulling off two channels out of the 24 available on that ring.
The laser won't make your weener any bigger, but they will make you go blind. :-) - alexred, on 10/12/2007, -0/+2Before anyone else makes silly comments like 12 DS1s on a DS3 or OC256, they should look at the SONET digital Hierarchy. In North America, the standards are DS1,DS3,OC3,OC12,OC48,OC192. That's one laser blinking on and off really fast to transmit TDM encoded data. The other technology mentioned is DWDM which is Dense Wave Division Multiplexing. That takes laser light and breaks it into different wave lengths or lambdas to transmit multiple signals.
- onestep, on 10/12/2007, -0/+1The reason the T1 is so expensive - -normally that includes the lease of equipment you will need on your end. In addition, you can divide up the channels how you please: 5 phone lines channels, 19 for data... or all 24 for data, etc.
Plus you are usually guaranteed a 99.9% uptime, where you won't get anything like that with your residential DSL or cable. - DJPandemonium, on 10/12/2007, -0/+1For all those making the comparison from T1 to your home broadband, besides the uptime and throughput guarantee differences, also keep in mind that the T-carriers are going to be full-duplex, whereas cable, DSL, etc are half-duplex. This (among other things) is an important distinction between residential and professional local loop technologies.
- einsteindesign, on 10/12/2007, -0/+1"Cable is still better than T1."
Only for the average joe.
Max upload on any tiered residential cable is about 768 kbps. T1 upload is twice that fast.
So it just depends on what you're needs are. Everything's relative. - Smokezz, on 10/12/2007, -0/+1Anyone who compares their home cable/DSL to a T1 is displaying their complete lack of knowledge on the subject...
- Hale, on 10/12/2007, -0/+1""A T3 is just 12 T1's......jackass"
for those of us that can multiply, 2x2x7=28, not 12. jackass. - DJPandemonium, on 10/12/2007, -0/+1Wow, they actually have a bunch of good reading material on the same level in their "Tech Notes" section.
http://www.dcbnet.com/apnotes.html - einsteindesign, on 10/12/2007, -0/+1The reason it's so expensive is because of network availabilit, plus it's full synchronous transmision -- unlike residential ADSL where UP is a fraction of DOWN, a T1 is fully 1.5 up and down. The "availability" I refer to means you have, always, 1.5 guaranteed. None of the "up to 1.5 Mbps" stuff.
There are advantages to be sure. But most people can live with the DISadvantages of ADSL for 1/10th the price. - DewayneSmith, on 10/12/2007, -0/+1http://www.t1shopper.com/
T3 - $7500 to $14000 per month. - speel, on 10/12/2007, -0/+0man imagine the amount of albums you could download with a t4 connection =D
- mooninite, on 10/12/2007, -0/+0What amazes me is that this techonology is still *very* expensive. You would think after 10+ years it would somewhat drop... but no... Still $500+/month for a basic T-1.
- cyborgver666, on 10/12/2007, -0/+0mooninite: T1 is that much? Wow, nevermind about T3/T4 then. that really is stupid after all this time its $500.
- Zappa, on 10/12/2007, -0/+0WoW thanks for that I have been learning a lot of this on the fly and this has helped fill in some of the holes.
- dolby, on 10/12/2007, -0/+0Cable is still better than T1.
- inactive, on 10/12/2007, -0/+0good luck finding a t4 service plan lol
- DewayneSmith, on 10/12/2007, -0/+0"Oh, and real men use OC3s. 155 Mbps, about $7k a month."
No, real men with huge e-penises use OC256, about $More-than-you'll-ever-make a month. - einsteindesign, on 10/12/2007, -0/+0Oh, and real men use OC3s. 155 Mbps, about $7k a month.
- dknighton, on 10/12/2007, -0/+0T1 lines can be had from a CLEC (not the Bells or large providers) for around 300.00/month. Reliability on the CLECS is usually very good. They simply resell the Bell circuit and manage it in their own NOCs. The price is typically because of the SLA's (service level agreements) that come along with the circuit. You can hold the company to the guaranteed reliability. DSL/Cable/etc. is a "best effort" service (read the fine print), and they make no guarantees on consistency of speed or availability. Fortunately, those services have gotten pretty good (with reliable carriers) so small businesses can rely on them enough that it justifies not spending the huge monthlies on T services.

- Genghis1, on 10/12/2007, -0/+0A T3 is 28 T1's - not 12
- inactive, on 10/12/2007, -0/+0"Still $500+/month for a basic T-1"
I have more than T1 upload (2mbps)
and way more dl (15mbps)
for $45 - oldcyborg, on 10/12/2007, -0/+0All I can think of, is WOW...That was more than I was prepared for.. :)
Cyborg :) - einsteindesign, on 10/12/2007, -0/+0Gbps, not GBps.
Dammit Digg, where's my "edit post" feature already? - MattZed, on 10/12/2007, -0/+0yeah all that you wanted to know, and like a million times more! +digg? yeah why not
- wyrmwood, on 10/12/2007, -0/+0"Even T3 sucks ass, jack ass. I use 1 Gbit connection."
Just one!? Yuck. I'm multihomed with 3 gigE connections pumped into a cisco 12k running bgp4.
Cool Digg though, that's more than I knew about t1... - einsteindesign, on 10/12/2007, -0/+0"you're"
dammit, make that "your". Too much Dew.
"OC256"
Good god man. 13 GBps.
Think of the kittens. - cyborgver666, on 10/12/2007, -0/+0so how much for say a T3 or T4 service plan? (didnt really read it, just skimmed to see if it talked about price plans)
- tsupersonic, on 10/12/2007, -0/+0Oops, I just learned we have two OC3 connections
- ham_man, on 10/12/2007, -0/+0Great read with great info. Now I know exactly, and I mean exactly, is powering my internet...
- Backlash, on 10/12/2007, -0/+0Gunther is awsome... he needs to release some more jams tho
- inactive, on 10/12/2007, -0/+0you don't have those rates guaranteed nor do you have guaranteed reliability. maybe you are outside the u.s. though and you do i don't know.
- inactive, on 10/12/2007, -0/+0"you don't have those rates guaranteed nor do you have guaranteed reliability. maybe you are outside the u.s. though and you do i don't know."
I've got verizon fios...I don't have guaranteed speeds, but i have never noticed a slow time, and I have never been disconnected...thats much better than you can say for CRAPCAST cable i used to have...i paid the same amount, got 3.0 dl, which was never that high, and got disconnected all the time - Zippo, on 10/12/2007, -0/+0When I grow up and have my own house, I want a buisness-grade T1 (or higher) connection XD
- UberThug, on 10/12/2007, -0/+0I forgot to add that i am poor.
- inactive, on 10/12/2007, -0/+0sbc is horrible and is a horrible company. can you say monopoly?
- UberThug, on 10/12/2007, -0/+0SBC DSL PWNS (considering the amount of cash all the others cost)
- UberThug, on 10/12/2007, -0/+0MONOPOLY! surely you jest?
- KidVicious, on 10/12/2007, -0/+0Doesnt my cable have 6mbps down?
- dolby, on 10/12/2007, -0/+0My cable speed is 15 Mbps and I just upgraded it to 30 Mbps!!!
- tsupersonic, on 10/12/2007, -0/+0All I need to know is my college has one and an OC3 I think, not too sure on that.
- pseudojd, on 10/12/2007, -0/+0what is a t4? is that like 28 t3's?
- spadin, on 10/12/2007, -0/+0What I don't get is howcome digital cable can carry 400+ digital tv channels over a coax line, but I have to hook up an HDTV with 20 different cables. On the same note, howcome I only get 1.5mbps download on cable? Can't they double/triple or more the bandwidth by taking away crap channels like MTV?
- bradsully, on 10/12/2007, -0/+0Damn 1.544mbps since 1960, all of the sudden my dsl doesn't seem so cool.
- CompIsMyRx, on 10/12/2007, -0/+0Goddamn, I want guarenteed bandwidth!
- chaosmachine, on 10/12/2007, -0/+0personally, i prefer my oc768.
- spadin, on 10/12/2007, -0/+0My bad. Cable here has 4mbps too. But people in Japan and Korea have more than 5 times that much for less.
- bugleboy624, on 10/12/2007, -1/+0Yikes! Information overload!! +Digg
- DewayneSmith, on 10/12/2007, -1/+0"Dammit Digg, where's my "edit post" feature already?"
Having fun tonight? - Zuhaib, on 10/12/2007, -1/+0This is stupid people comparing T1 to cable, hell even DSL cant stand a chance.
You forget that with T1 you are given a SLA of almost 99.99% up time, and that its a direct connection. No one else line to mess with your. No finger pointing if something goes bad, unlike Cable or DSL.
Also, unless cable has changed its tech you are on a LAN as just like at home, and everyone can see your traffic. I dont think people using T1 would want that.
And cable your coming over your normal phone copper, again something you dont want if your running a server.
At our work we used an ADSL line as testing for a server (we are a small biz BTW) and one day our CO did a DB upgrade and boom we where with no DSL for almost 4 weeks. We now use SDSL as we get 99.99% SLA, its still no T1 but it leaps and bounds over ADSL. You go have fun with your cable modems fragging ppl in CS, but when you need to do some serious work T1 is what is called for. Oh and BTW, check your ToS on your cable modem, see what it says about servers. -
