A T1 circuit is a digital telephone circuit which connects one site to another comprising the basics of a Telemedicine or Telehealth network. The circuit consists of (24) 64K channels which comprise a 1.544MB connection.

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...

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...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

Answer - With a piece of equipment called a multiplexer (which is similar to a channel bank), the T-1 can be distributed into data circuits and voice channels. For example, a T-1 could be used to carry 12 telephone lines plus two data circuits at 386K baud. This would be an example of an integrated T1 circuit. See similar questions...

T1 access is quite simple, it bypasses your local telephone companies switching equipment and directly connects your customer premise with your long distance carrier. This is where the major savings comes in as it reduces the switching costs associated with the switching equipment at your local telephone company. This service is a commercial product and is recommended for customers billing $1500+ per month in long distance charges or more. See similar questions...

When a carrier gives you the option of purchasing a full T1, you can get the full 1.544Mbps circuit unchannelized direct into the Internet (or Frame Network, or Point-to-Point); also known as a clear channel T1. A Fractional T1 is a channelized T1 with only some of the channels turned on. Fractionals are normally priced in terms of Kbps. For example you can get 384kbps, 512kbps or 768kbps from most carriers.

Because T1s can be broken out into channels, voice and data can run side by side on the same circuit. They require a device to convert the signaling from that used on the T1 into signaling that can be used by the phone, the equipment, or router. The technical name for this process is multiplexing and the equipment required is called a multiplexer; but it is known more commonly as a channel bank, CSU/DSU or T1 card. See similar questions...
