T1 Definition | T1 Line Definition | T-1 Definition | T1 Defined | Definition of T1 |
T1 definitions. T1 lines and T1 definitions come in several variants. T1, for example, is also known as DS1 (or Digital Signal 1). You can also find it commonly written with a hyphen as in T-1 or DS-1. T1 was developed by Bell Labs in the 1960s. It is an acronym for "Transmission Level 1." A compilation of various definitions of T1 and descriptions that define T1 has been compiled and presented here for your convenience.
"The common corporate link to the outside world, a T-1 line, offers speeds of 1.5 Mbps, and is able to max out at about 15 GB of information per day. According to Geoff Tudor, founder and senior vice-president for business development and product strategy at cloud storage company Nirvanix, if one assumes a corporate employee generates 3MB to 5MB of data per day, once you get over 300 employees sending their files to off-site cloud storage for backup, the T1 is tapped out. Over one of the fastest telcommunications options, an OC-48 line with speeds of about 2.5 Gbps, it will still take about an hour to send 1 TB of data.” T1 data per day. 1TB over T1. Network capacity per day. Multiple definitions of T1 glossary. (Stacey Higginbotham, “Cloud Storage Could Mean Fat Pipes for All,” Business Week, April 3, 2009)
T-carrier lines
“A T-carrier line is any of several types of digital lines that carry multiple signals over a single communications line. Whereas a standard dial-up telephone line carries only one signal, digital T-carrier lines use multiplexing so that multiple signals can share the telephone line. T-carrier lines provide extremely fast data transfer rates. The most popular T-carrier line is the T-1 line. Businesses often use T-1 lines to connect to the Internet. A fractional T-1 line is a less expensive albeit slower connection option for home owners and small businesses. Instead of a single owner, a Fractional T-1 is shared with other users. A T-3 line is equal in speed to 28 T-1 lines. T-3 lines are the most expensive connection method. Main users of T-3 lines include large companies, telephone companies, and service providers connecting to the Internet backbone.” (Gary B. Shelly, H. Albert Napier, Ollie Rivers, "Ways to Access the Internet and Web," Web Design: Introductory Concepts and Techniques, 2 edition, December 1, 2005, p. 13)

T1 dedicated line
“T1 is a
dedicated line that has a much higher capacity than ordinary telephone
lines. Capable of handling data at more than 1.5 Mbps, it can be used
for purposes such as links to ISPs [Internet Service Providers] or
linkages for private computer networks. The plus with T1 lines is the
capacity is great enough to cover large volume usage. The downside is
the expense, with costs (usually monthly fees paid to telephone
companies) increasing with the distance covered. But many businesses
feel it's a worthwhile investment to support their information sharing
needs.” A T1 line transmits data at speeds of 1.5 Mbps or more. How much is a T1? (Mark Rowh, “Cyberspeak: Let's get alphanumerical,” Office Solutions, October 1, 2001)
T1 fiberoptic or copper line
“A T1 line is a copper or fiberoptic line that creates a ‘pipe’ capable of blowing through larger datastreams.” (Diane Petryk, “Sunbury police join child alert plan,” The Daily Item, Sunbury, Pennsylvania, April 2, 2010)
T-1 leased line connection.
“A leased-line connection for carrying data at 1,544,000 bits-per-second. At maximum theoretical capacity, a T-1 line could move a Megabyte in less than 10 seconds. That is still not fast enough for full-screen, full motion video, for which you need at least 10,000,000 bits-per-second. T-1 is the fastest speed commonly used to connect networks to the Internet over 24 multiplexed 56 Kbps channels.” (Russell Lee, “Telecommunications Network Links – What Type of Bandwidth is Available?," Information Engineering Technology, Department of Engineering and Computer Technology, College of Education, Distance Education, University of West Florida, Pensacola, Florida, July 18, 1997, Slide 8)
T1 lines
“T1
lines are the standard for dedicated business Internet connectivity.
They function as the veins and arteries that carry Internet traffic to
its destination. In spite of its limitations, T1 is a proven, reliable
technology that currently meets the need for medium-speed, high
reliability Internet access by institutions of many sizes, and it's
likely to be around for a while.” Shop T1. (O'Reilly & Associates press
release introducing Matthew Gast and his book "T1: A Survival Guide,” in “T1 survival--not just for the fittest anymore,” M2 Presswire, M2 Communications LTD, September 18, 2001)
“High-speed dedicated line which allows users to access the Internet at speeds of 1,300,000 bps [bits per second or bytes per second; also known as bit rate]. Standard modems today [1997] top out at 56,000 bps.” 1,300,000 bytes/sec. 1,300 kbps. (No author, “Glossary of Internet terms,” Minneapolis / St. Paul Business Journal, Friday, November 7, 1997)
T1 or T3
"Levels of high-grade, high-capacity phone lines. Many companies have T1 lines. T3 lines are found at a few big corporations, government and military facilities and within a phone companies' network." (No author credited, “Learning The Net Lingo,” The Virginian-Pilot (Norfolk, VA), July 8, 1996) Where can I find a T3 definition? How much does a T3 line cost?
