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.

If you run your own webserver you can have as many as you want. Often your ISP will provide some space for a web site with your account.

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

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.

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.

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...

In most cases the installation of the T1 service is handled by the ILEC (Incumbent Local Exchange Carrier) such as Verizon or SBC. These companies are responsible for the last mile of service from the POP (Point-of-presence) to the customer's location. For example, with T1 service the ILEC will come to the customer's location and install the smart jack (RJ-45) and test the circuit through to the T1 carrier. The provider pays the ILEC for the installation of the line and may or may not ...

Integrated ones are the most common integrated service, but other access types are capable of similar configurations. Some new DSL products offer local, long distance and Internet service bundled on the same circuit. T3 (also known as DS3) is also capable of supporting multiple services on the same circuit, usually long distance, Internet and WAN (Wide Area Network) services.

The T1 connection is a dedicated link. Unlike ISDN and analog modem connections the T1 connection is up 24 hours a day. This gives you some additional options like running servers.

Just because a carrier says that they are providing a T1 to the Internet; do not assume that all carriers are providing the same T1 service. Every carrier uses different technology and design in transmitting data from your location to the Internet. Large carriers like AT&T, Qwest, Sprint and WorldCom use fiber optic backbones that they own and operate. These networks are highly sophisticated and redundant and can move data at speeds up to OC-192.

Most routers capable of providing protocol switching for T1 service can be used for Frame Relay. Frame Relay works by encapsulating the data to be delivered into a packet, sending it through the network and breaking it apart once it arrives at the destination location. The process of encapsulating and breaking apart data is often referred to as protocol switching and can be handled by most modern routers.

For the most part any long distance carrier who provides switched long distance service can provide dedicated long distance via a T1 or T3 line. Examples of these companies include AT&T, MCI WorldCom, Sprint and Qwest. Choosing a company to provide dedicated T1 or T3 long distance service normally involves a review of their prices and per minute rates, which vary greatly from provider to provider.

For most sendmails, no special configuration is required. Eric Allman tells me that if FEATURE(always_add_domain) is included in sendmail's configuration, you can leave the rewrite option off. If your sendmail complains ''sendmail does not relay'', make sure your sendmail.cf file says Cwlocalhost so that sendmail recognizes 'localhost' as a name of its host.

Answer - The main advantage of T-1 is cost savings over equivalent service on regular analog lines. In general the cost of most 24 channel T1s is about the same as 12 standard telephone lines. This enables a business requiring 24 phone lines to do so for the cost of 12. Another advantage is that T-1 is a digital transmission and therefore less prone than regular phone lines to loss and interference.

Answer - Speed is the primary reason for data over T1. If a company transmits large files regularly outside their office an T1 can be a great asset as well as if they receive large amounts of Data. With the expansion of the internet and the requirement to send data at higher speeds, T-1 technology has been essential for dedicated T-1 lines.

We offer a T1 pre-installation screening to help ensure a smooth installation of the FAXCOM fax server. While T1 service can provide important advantages to an organization - such as cost savings, channel density and expanded inbound routing capabilities - properly integrating T1 service is a more complicated process than installing a simple business phone line. T1 contains variations that must be explicitly configured by mutual agreement between the fax server and the PBX or phone company.
