When it first came out in the 90's the Digital signal 1 line, or DS1 was used by large companies and phone companies only. However, it's now used in many different ways and some of them are by normal people who are connecting through their home desktop. First thought up by Bell Labs the DS1 or T1 was a way in which both data and voice signals were able to transmit together.
A DS1 circuit is made up of 24- 8 bit channels which will send and receive information. The information that is coming in from this type of signal can be up to 1.544 megabits a second. Back when it first came out that was a huge jump in the ability of internet connection. Though today there are much higher rates, still this predecessor was one huge leap in technology.
Information on a was framed, either via a super frame idea, where 12-193 bit frames would come across. Or the extended super frame which doubled the output speed. Both were fabulous, but when this technology first came out it was used only in business. A bit too expensive for a household to undertake the change to this type of technology.
However, as technology moves on, the cost of internet connections and speeds will change. Allowing the DS1 to be used by millions of households. A way in which a mother who works from home can pull up research at faster speeds than she ever imagined. Or how a kid can get information for his next report.
Some businesses do still use the DS1 internet connection. Cell phone companies use it to send the major signal out to all the smaller towers they have located around cities. This makes cell phones work better, and that connection signal you see on your cell stay well above where you need it.
Like any internet connection though, the DS1 is not without problems. They do have problems in connectivity like anyone else. There are three alarms that will go off depending on the situation of the problem. Red is the one you really do not want to see, it means you have no data coming or going. It's a loss of connection.
You may see a yellow alarm which isn't good either; it will show that your location you are getting data from has experienced a red alarm. Though you can still get some things in, you will not be getting them near as quickly. The blue alarm is a way in which you will be able to know that your equipment has a problem with either receiving in data or voice information. When seeing a blue alarm you will need to call in maintenance to fix the problem.
With many types of connections that can be used to get on the Internet, the DS1 Line is only one of those. It is one of the faster that is able to be used on a home computer though. A lot of the components in a regular desktop cannot handle the higher speeds that are being used at present by large business.
