Definition 1. - Digital carrier with a speed of 45Mbs. Equivalent of 28 DS1s. Also called T3.

Definition 2. - Digital Signal Level 3. Framing specification used in transmitting digital signals at 44.736-Mbps on a T3 facility (United States) or at 34.368-Mbps on an E3 facility (Europe).

Definition 3. - For many years, the fastest, and unfortunately, the most expensive way to connect to the outside world was through a ds1 or T1 connection. DS stands for Digital Signal or Digital Service. Now more commonly used and not near as expensive as it used to be, T3 or Data Service Level 3 is the connection of choice for many large companies and places that require a lot of bandwidth. DS3 technology is used for T3 lines and allows connections to the Internet to reach speeds of up to 44.736 megabits per second.

Definition 4. - T3 Bar Code service is a digital, dedicated private-line service giving you high capacity for any combination of data, voice or video applications. The versatility of T3 makes it ideal for data-intensive users with large backbone applications or private networks requiring channelized transport. The point-to-point structure of T3 Service affords greater economies of scale by combining 28 DS1s or 672 separate 64 Kbps channels onto one communications path.

t1 internet service is as ubiquitous as DVD players but the choices are much more varied. Ready to learn the basics and find a connections? In general, T-1 is a member of the T-carrier system. T-carrier is a communications system used for carrying voice and data transmissions in a digital format. T-1 meets the needs of businesses having multiple users on a system requiring fast speed and broad bandwidth. For a fixed monthly rate, businesses with 20 or more users can communicate via both voice and data. A Full T1 can accommodate as many as 24 users working at 64 Kbps.

'T-1 is made up of 24 digital channels. This requires a digital connection device (CSU/DSU {customer switching unit/digital switching unit}) to connect to four wires to carry the information. All T1 lines require that a Channel Service Unit (CSU) be connected between your Data Terminal Equipment (DTE), i.e., a personal computer, and the T-1 line. A CSU serves both as a surge protector (to protect your equipment from voltage anomalies such as lightning) and a monitor of the line itself.

As mentioned previously a T1 connection is capable of delivering 1.5Mbps. DSL connections are also capable of delivering this speed however they are not nearly as reliable as a T1 connections and should not be considered as a business connections unless it's SDSL and even then you will likely have some downtime. If you have critical information being hosted in your office or have a large number of users accessing the internet on a regular basis, consider getting a T1 connections. Also remember to get a professional's assistance when you search for your provider. Each company will tell you their connection is the best available but a broker will act as your agent and help you find what's right for you.

Is it time to upgrade to a T1? There are several factors to consider when examining you current DSL connection and the possiblity of replacing it. For many people the biggest factor is reliability and if reliability is critical to the applications you run over your connection you should seriously consider replacing your DSL connection with a T1. DSL is a quick and cost effective method of acquiring high speed bandwidth however it is not intended to support commercial applications or large numbers of users as is a T1 connections.

Reliability becomes critical when customers or employees depend on your connection for immediate responses. If your customers use your connection to access your databases or your server or the internet then reliability of your connection is critical. If your employees depend on your connections because you host the e-mail server in house or host web servers, your connections is considered critical. A critical connection can be viewed much like a life line, without which your business would be negatively impacted. Your monthly savings of having a sub-par connections will not make up for the loss in productivity of your employees or loss of customers when your DSL connections gets bogged down or cut off. To reiterate, ciritcal connections should be supported with a T1.

Many customers are extremely price sensitive and cannot afford the cost of a T1 which can be as much as 20 times more expensive than a full T1 connection. Residential customers who are most sensitive to price should not consider a T1 circuit unless then have a business reason to pay for such a circuit and cannot access DSL service. Most people don't realize that a DSL connection can be just as fast as a T1 at 1.5Mbps. The shortcoming of DSL is that it is oversubscribed. This means there is a finite amount of bandwidth available and a customers speed can drop if other customers in the neighborhood decide to use their service. SDSL (Synchronous DSL) is a business class DSL and is ranked as a higher priority than residential DSL or ADSL (Asunchronous DSL). This means it is not oversubscribed to the extent than ADSL and is subject to fewer bandwidth restrictions. In short, if price is your critical factor go with DSL. If reliability is the critical factor purchase a dedicated T1.
