DSL run over regular phone lines. T1's are qualified data circuits with more extensive testing and monitoring (qualified loop).

Simple answer - T-1 is a type of telephone service capable of transporting the equivalent of 24 conventional telephone lines, using only two pairs of wires. Technical Answer - The T-1 was originated by AT&T in 1962 as a method to be able to send additional data along a common 2 pair of copper wire. The technology was originally to be used for "long-haul" voice communication, but in recent times has been used for data transmission. See similar questions...

For companies considering the many alternatives for long distance service, there are two main formats commonly used to transmit long distance voice traffic. The most ubiquitous form of long distance calling is the switched call. These calls originate from regular POTS (Plain Old Telephone Service) lines and are routed through the local telephone company's central switch. Dedicated long distance is transmitted over a digital T1 line from the customer's location through the local telepho... See similar questions...

The primary difference between DSL and a T1 is in the level of over subscription that occurs before the service reaches the end user. When you purchase a full T1 of Internet access, what you are generally getting is access to 1.544 Mbps of transmission on the carrier's network, regardless of what other customers are transmitting and receiving. To better illustrate this, let's assume that a carrier has capacity for 150 Mbps at any given time. This means that the at the most, they would ... See similar questions...

DSL is Faster: ISDN provides two voice/data channels, each at speeds of 64 Kbps, while DSL is predominantly a data service providing up to 1.5 Mbps downstream and up to 512 kbps upstream. Business DSL offers T1-like speeds of up to 1.5 Mbps-more than 10 times faster than ISDN! DSL is "always on": ISDN is a dial-up service (like a regular telephone line) that's digital and carries both data and voice; Business DSL is "always connected" See similar questions...

T1 is a technology that bundles several phone lines together to provide downstream access speeds of 1.54 Mbps. The decision between DSL and T1 access when DSL is readily available is a straightforward one due to pricing. Normally, for the same high bandwidth access, a business will pay significantly more every month for a T1 line as it would for DSL. Additionally, installation for a T1 line is generally far more expensive than installation and setup of DSL services. See similar questions...

Most telecom carriers offer T1 services through two main channels. Customers can purchase T1 services directly from the carrier via a direct sales representative or indirectly through an agent or partner. Bandwidth Resource is an agent for over thirty carriers and will present prices and services from multiple T1 providers, allowing the customer one point of contact for T1, voice and data services.

Unlike regular T1 service, integrated connections require sophisticated equipment on the carrier's side to split the 24 channels into diverse services. Typically, Tier 1 providers are capable of providing integrated services for Frame Relay, VPN, Internet and dedicated voice service. Examples of these providers include AT&T, WorldCom, Sprint, Qwest, Broadwing and Cable and Wireless. See similar questions...

There are significant differences between ITSN and DSL: DSL is faster. DSL is also "always connected," while ITSN is a "dial-up" service (like a regular telephone line). ITSN charges for per-minute use, versus the static, monthly DSL charges. Lastly, the DSL regional network does not require the costly and time-consuming switch upgrades that prevent the rapid deployment of ITSN. Hence DSL is available to more locations.

The main difference between cable modem and DSL technology is the network underlying the service. DSL service uses the public telephone network for transmission while cable modems use a completely separate broadband, high-speed network. Telephone solutions tend to degrade and slow down the further away your home is from the telephone company's central office. See similar questions...

A T1 is a high speed telecommunication line that can carry 24 digitalized voice channels, or it can carry data at a rate of 1.544 megabits per second. TI lines carry about roughly 60 times more data than a normal dial-up modem. See similar questions...

Our service is up to eight times faster than 256K DSL and nearly twice as fast as most cable. DSL and cable modem upload speeds can be much slower (128-384Kbps) than the download speeds (512Kbps-4Mbps). With our service your download and upload speeds are the same. For example, if you subscribe to our Residental Plus service you get a Asymmetrical, 384/512Kbps sustained service - download and upload, with downloads bursting to between 3Mbps and 7Mbps and uploads up to 1.5Mbps.

It is high-speed internet access over your existing phone line. DSL converts your existing analog phone line into a high-speed digital phone line. Using ADSL (asymmetric digital subscriber line) technology, it delivers up to 1.5 megabits per second - that's at least 25 times faster than a standard 28.8Kbps dial-up modem!

The difference between the three high speed Internet services are how you, the user, connects to the Internet. DSL uses the phone lines but you must be within 18,000 feet from the co-location facility to receive the service and have an active phone line. Cable modem uses the existing Cable TV lines to deliver its broadband service. Availability is to limited areas and the service is a shared connection, thus speeds can slow down when a lot of people in the same neighborhood are online. See similar questions...
