Business Internet T-1 Service Description


An Internet T1 line is a high-speed connection to the Internet over a dedicated copper, fiber, or Ethernet using a telecom standard that was developed by AT&T Bell Labs for North America and Japan and transmits data packets at a total speed of 1.544 megabits per second (Mbps) and usually connects from the customer premise directly to a large fiber optic Internet Service Provider (ISP) backbone.

When used to provide "last mile" Internet access to an Internet Service Provider's (ISPs) Point of Presence (PoP), a local loop, "access" T-1 is provisioned as unchannelized and provides 1.536 Mbps of bandwidth as an unchannelized raw bit stream of 1.536 Mbps in both direction plus .008 Mbps of framing bits.

The term, "T1 or T-1" itself is short for "Trunk Level 1," which is a standard for digital transmission under the DS (Digital Signal Level) hierarchy. Over copper, a T1 is delivered by connecting two pairs of unshielded twisted copper wires between the subscriber location and the provider's central office. One of the twisted copper pairs is for transmitting data and one pair is for receiving data. Working together, the four-copper-wire transmission media carrying the DS digital signalling standard combine to produce a full duplex symmetrical (bidirectional) circuit. When delivered on fiber, a fiber pair is used as opposed to the 4-wire copper configuration.

The advantage of an Internet T-1 over DSL or cable Internet service is that the full 1.536 Mbps of available bandwidth delivered by a T-1 connection is guaranteed 24 x 7 by the provider under a Service Level Agreement (SLA) that defines service reliability metrics in clear terms.
