The T1 line is a dedicated connection between the service provider and the client. It uses an advanced telephone line to send more data than a traditional standard analog line that carries a single data channel at 64 Kbps. How does at T1 line work?
History of the T1 line
Developed by AT&T Bell Laboratories in the late 1960s, traditional T1 lines use copper wire, but most new installations use optical fiber. T1 lines use pulse-code modulation, which allows sharing encoder and decoder over multiple voice links. Channels are pre-configured to carry voice or internet data. The speed of the T1 line is constant and constant. The T1 line can carry 24 voice channels for phone calls or digital data at a speed of 1.544 Mb / s, and using compression, the transferred channels are double to 48.
Most of us know a normal business or landline line from a telephone company. A normal telephone line like this is provided on a pair of copper wires that transmit your voice as an analog signal. When you use a normal modem on such a line, it can transfer data at approximately 30 kilobits per second (30,000 bits per second).
An important advantage of the T1 Internet over cables is its reliability and stable source of bandwidth. In fact, the T1 Internet is often accompanied by a Guaranteed Service Level (SLA) agreement that guarantees performance levels and “downtime” of 99.9 percent. Because T1 works through a dedicated circuit, you won’t compete with other Internet clients for bandwidth, as you would with a cable Internet service. You’ll have full access to bandwidth, which means speed.
When it comes to choosing an internet connection option, keep in mind the factors identified. T1 is a solid choice because it offers reliability and can keep multiple computers connected at high internet speeds. But it’s expensive. The cable is much more budget-friendly, however, you’ll share the bandwidth (and thus the speed) with your neighbors.
T1 vs. DSL
Another option you may come across Internet services are Digital Subscriber Lines, which are often called DSL. This type of internet service is usually used in small businesses with approximately ten employees or less. DSL is almost always cheaper than the T1 line, but it is also much less efficient and effective in terms of reliability and consistency. In addition, DSL is not always available everywhere, but it will be difficult to find an area that does not offer access to the T1 line.
Reliability and Internet T1
Reliability is the key to the value of the T1 internet connection, which makes it an indispensable element of company connectivity. In general, T1 is known to be more reliable than DSL and cable, and if a particular area fails due to bad weather, for example, those with T1 lines will have connections first before those with DSL or cable connections. MTTR (average repair time) can be as low as 4 hours for T1 connections compared to MTTR 48 hours for DSL / cable connections.
Disadvantages of the T1 line
The main disadvantage of the T1 internet connection is the cost. T1 lines are more expensive than cable or DSL. However, if you are thinking about the cost of the T1 line, you also need to think about the ROI of this service. Downtime is extremely expensive for any company. Every time your internet connection is unavailable, you lose potential sales.
