What do 28 T1 lines combine to form?

The combination of 28 T1 lines results in the formation of a T3 line. Each T1 line has a data capacity of 1.544 Mbps. When you aggregate 28 of these lines, the total capacity reaches approximately 44.736 Mbps, which characterizes a T3 line.

T3 lines are commonly used for high-bandwidth data transmission and can handle the requirements of larger data traffic, such as that needed by businesses or data centers. In terms of telecommunications infrastructure, this aggregation is a standard practice to enhance data transmission capabilities and manage increased bandwidth demands.
