What is a T1?

T1 is a high-speed digital telephone line that can accommodate up to 24 lines or trunks. This type of service transfers signals at 1.544 megabits per second. It may be used in place of separate local trunks and lines from the local telephone company. Optical fibers may be used for all or part of the circuit path. Clear Rate can provide T1 services that connect directly with our switch and bypass your local telephone company. T1’s require a four-wire circuit between the user location and the service provider’s central office. There may be other special equipment required to work with telephone or data systems.

Should I consider a T1?

T1’s major advantage is economic. If you need at least 10 or more voice-grade channels that connect to your local or long distance service provider, or if you have need for high-capacity data bandwidth (256 kbps to 1.544 mbps), a T1 may cost less than alternative means of access. It is important to keep in mind that while the initial costs for equipment and installation are higher than standard phone lines, T1’s can be the most cost effective alternative to standard phone lines over an extended period of time.

What are the different types of T1?

T1 service is available in several configuration and application variations, including:

  • A Single Channel of 1.544 mbps capacity. Such T1s are usually used for a dedicated connection between data devices in separate locations, for connection between a user and a data carrier, or between a user and an Internet Service Provider (ISP).
  • A Channelized T1 is multiplexed into separate channels. The most common variety creates 24 channels at 64-kbps that can be used for voice data connection to local and/or long distance service providers and ISPs.

What are the various costs associated with T1?

  • Fixed monthly charges may consist of service, CO termination, multiplexer functions, and access coordination.
  • Installation charges
  • Port charges for access to service providers
  • Local loop charges based on the distance between you and the service provider’s central office.
  • Usage charges may also apply.
  • Equipment may include a “smart jack” network interface, a CSU/DSU, and a channel bank or multiplexer or DS1 card in the equipment utilizing the T1.

Associated charges would also include local, long distance, data or Internet service.
