system, of which the T1 is a part.
The T1 (or T-1) carrier is the most commonly used digital transmission service in the United
States, Canada, and Japan. In these countries, it consists of 24 separate channels using pulse code
modulation (PCM) signals
with time-division multiplexing (TDM) at
an overall rate of 1.544 million bits per second (Mbps). T1 lines originally used
copper wire but now also include optical and wireless media. A T1 Outstate System has been
developed for longer distances between cities.
It is common for an Internet access provider to be
connected to the Internet as a point-of-presence (POP) on a T1 line
owned by a major telephone network. Many businesses also use T1 lines to connect to an Internet
access provider.
