What is a T 3 or a T1?

[kite]

What is a T3 and T1 do you use it with your phone line or is it just something you sign up for


What is the fastest modem that uses the phone line please tell me

[camaro]

DSL is the fastest that used the phone line. Call your phone company about the rates and speeds. I get 90K/s downloads with the slowest DSL. Uploads are 20K/s. T1 downloads are 170K/s.

Note these are what I got when I tested them. It depends how far you are from certain stations.

A T-3 or a T-1 is a type of digital connection that can be used for a variety of purposes. T-1 lines can carry data transmission (far faster than standard phone lines) they can carry phone transmissions, they allow for things like VPN (Virtual Private Networks) and they are exorbinately expensive.

I may be wrong on this, but I believe a T-1 has a maximum capability of 150 K/s (bytes, not bits) while a T-3 has a capability of 450 K /s (bytes, not bits). However, I also know a T-1 leases for around $1500 per month--not exactly the cheapest option on the planet. I'm not even aware of a company that would lease a consumer a T-3.

The fastest available modem technology is going to depend on where you live. The following options may or may not be available:

ISDN
ADSL

ISDN is an older, slower service that typically runs between 70-110 dollars per month and provides twice the speed of a standard phone connection (56K). In other words, you get about 11/K a second upload or download.

ADSL is a newer type of service that costs only around $30-60 per month depending on your location and service options. ADSL typically offers around 384-1024 Kb/s (bits not bytes) with about a 100-200 Kb/s upload speed (bits not bytes).

ADSL is the best option if you can get it. Its availablity and range are questionable, however, because I don't know where you live.

You might also look into cable modems. These typically offer speeds of 384 kb to 8 mbps but speeds will vary widely. One advantage of ADSL is that your speed does not change--in cable modems your speed and security can both be compromised by other users on the network.

I hope this helps.

The "T" series (my name for it) internet connections are ULTRA fast and ULTRA expensive. Only businesses and colleges can afford it. I believe there is T4, but have never seen it advertised personally on the Internet Gaming Zone as a connection (people usually put the name of their high speed connection so as to get people to go in their games). That concludes my limited knowledge http://sysopt.earthweb.com/forum/smile.gif

Holy Mother of the Marshmallow Man...posted at close to same time as you. WELL then http://sysopt.earthweb.com/forum/smile.gif. Does a T4 exist/in developement?

both a t-1 and a t-3 use phone wire but they use many pairs of them and are rather expensive in my area a t-1 goes for about $1,200 a month well a t-3 is near $20,000 luckly enough my company has a t-3 line so i cant to use it all day long but no one could ever get it for home use

how and how much would a idsn cost and about how much would a cable modem cost

[johnpaul]

Cable costs me $40/month. The modem and installation were free. I use AT&T Broadband, formerly Media One, and I live in central Calif.

A T1 is 1.54Mb/s
A T3 is 45Mb/s
A DS3 is 40Mb/s

Telecom companies use these types of connections to link their ISP's to the internet backbone. For example, the ISP that I use, which is also the telecom company here, has a dual-DS3 connection directly to UUNet. If your a home user; ISDN, Cable, and or DSL would be a lot more cost affective.

here in the u.k there are companies that are providing a satalite based internet system that offers up to 2Mbit download , but the down site is the upload is provided by a regular 56k modem but they say it costs around £40 a month ! any similar stories?

[waferdog]

This is probably more info than you were looking for.

An explanation of the T system:

Data Speed chart (I'll take the OC-256):

[Mungla]

Learn something new everyday. I was under the impression that DS3 and T3s were at different speeds. Interesting.

BTW, I'll take an OC-192 as well. Although, I would love to have fiber coming to my house with multiple wavelengths, all running an OC-192. Can you imagine having 8 x OC-192 running to your house?! Mega server heaven!

[Dovaka]

im not sure why you would really want 8 of them id very very happy with a oc-3 speaking of which hear is a link to a company that sells something like them for $999 a month http://www.cogentco.com/home.html

Well I tell you I have a ADSL and it's 604/128Kbs when tested ranges abut 490/Kps downloading and about 118/Kps the company is http://www.speakeasy.net/splash.php very good company.They had a few problems in the start, when they were overloading the severs but they just recently added more severs and POP severs and its running very good.
