Definition 1. - The T-carrier system, introduced by the Bell system in the US in the 1960's, was the first successful system that supported digitalised voice transmission. The original transmission rate (1.544 Mbps) in the Addy T1 line is in common use today in ISP (Internet Service Provider) connections to the Internet

Definition 2. - A high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bits per second. A T1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a T1 is basically too large and too expensive for individual home use.

Definition 3. - The T1 (or T-1) carrier is the most commonly used digital line in the United States, Canada, and Japan. In these countries, it carries 24 pulse code modulation (PCM) signals using time-division multiplexing (TDM) at an overall rate of 1.544 million bits per second (Mbps). T1 lines use copper wire and span distances within and between major metropolitan areas. A T1 Outstate System has been developed for longer distances between cities.

Definition 4. - A type of high speed Internet connection that provides a great deal of bandwidth. Many businesses lease T1 lines to connect to the Internet, but because they are expensive and offer more bandwidth than most small businesses and homes need, they are not realistic solutions for small and low-demand Internet users.

If a full T1 isn't in your budget, you need to consider a fractional t1 line. Why not get all the advantages of T1 even if your not in a market for a full T1? For many people the biggest factor in their decision 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 fractional 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 are T1 connections.

One drawback to fractional T1 service is the price. Even though you won't have a full T1 you will be paying quite a bit more than you did for your DSL connection. This is due to the structure of T1 pricing. A T1 connections is established by providing a "loop" or wire from the users premesis to the CO where the service provider has equipment. Part of the cost of a T1 is the "loop charge" or the monthly rental fee for the wire that is rented from the local phone company. Once the connection reaches the CO it can access the carriers network and reach any destination. This loop is paid in full whether you use a fraction of the available bandwidth or the full 1.5Mbps and therefore your price for a 768Kbps fractional T1 connection will never be half the price of a 1.5mbps full T1 connection.

Although the price reduction is not what you might expect it to be, this may put a T1 in your budget and be a great way to get dedicated service into your building. Once you have fractional service upgrading to full service is easy. Fractional service typically comes in 256Kbps increments from 256Kbps all the way to a full T1 at 1.5Mbps. Find the service that's right for you, but if you are supporting critical services think reliability. 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 or ASP type products, your connections is considered critical. A critical connection can be viewed much like a lifeline, without which your business would be negatively impacted.

As the VPN market approaches maturity at a brisk pace, vendors have been forced to rethink the tradition identity of their IP Security-based technology for letting users securely access enterprise resources via the Internet. Most large companies in need of linking their offices together have done so on frame relay networks. Although frame is still a useful product many users have found that the reduced cost of VPN gives them an attractive alternative.

'During the last 18 months, vendors have pushed VPN technology into different devices, have lessened the distinction between VPN and firewall products, and have demonstrated a strong willingness to deviate from standardized technology to meet corporate remote access requirements. VPN services now come bundled with many dedicated services and several service providers are using VPN products as a loss leader so they can sell circuits. When investigating the use of VPN products make sure you speak with a professional who can guide you through the strengths as well as the weaknesses of the product. While it is a cost reduced alternative to frame it is a different product and should be thoroughly researched.

One of the advantages of a VPN is that internet access is not based only on the hub and spoke layout. The users away from the hub are able to access the internet through their own connection rather than going through the hub and creating a bottleneck. Users will only need to connect through the hub if they need to access information from the central database. When researching alternatives such as VPN, like always, we recommend you consult with a professional and not just a salesman for a VPN company. Make sure the individual you speak with is unbiased and will give you the strengths and weaknesses of each product. We recommend one of the brokers at T1 price for unbiased recommendations of multiple carriers.
