Things To Know About A T3 Line
T1 line and T3 line are the two most prevalent categories of leased lines that are used in the arena of telecommunications. T1 and T3 lines are examples of reserved circuits and both operate on fiber-optic or copper cables. A T3 line is a super high-speed connection that is capable of transmitting data at the rate of 45 million bits per second.
A T3 line has sufficient bandwidth to transmit real-time full-motion video and huge databases over busy networks. A T3 line represents a bandwidth equal to 28 T1 lines or to about 672 64-Kbps voice or data channels. T3 lines are generally used as the framework of a business headquarter network. Around the globe, major Internet service providers have T3 lines as their fundamental structure.
Most organizations typically rent T1 and T3 lines on a monthly or yearly basis. Despite its great usability, the high cost of a T3 leased line often stops most units from leasing them. For a month a T1 line can cost $250 or more whereas one T3 line usually is starting from $2,500 per month.
The primary purpose of a T3 line is to provide private voice and/or data networking amongst geographically separated location of an organization. This is one reason that mostly only large corporations and universities campuses have requirement for the installation of T3 line as their networking base with high-volume network traffic.
However, today with the advent of IP telephony, voice-over-IP and virtual meeting concepts, the use of T3 lines is increasing at a growing pace. Another factor for larger corporations going for a T3 line instead of normal T1 line is that when they need more capacity they have to buy it for even more than what a T3 line would actually cost.
Today with the economy being the most fragile probably since The Great Depression, more and more organizations are looking to reduce their overhead expenses by cutting down of discretionary spending and variable costs such as travel costs, meeting expenses and transportation, etc. So these organizations that are tying to bring their costs down also have to look for ways to not let it affect their business.
A T3 is surely costlier than a T1 line but then it has some clear professional benefits as compared to T1 line. And at the rate use of Internet is growing the importance and existence of T3 is only set to catch pace from hereon.
