Question

A T3 consists of how many T1 lines?

Answer 1

A T3 line consists of multiple T1 lines bundled together to form a higher bandwidth pipe. A T3 line consists of 28 T1 lines, with each T1 line having a capacity of 1.544 Mbps.

Step-by-step explanation:

A T3 consists of 28 T1 lines. A T1 line operates at a transmission rate of 1.544 Mbps (megabits per second), while a T3 line operates at a transmission rate of 44.736 Mbps. To calculate how many T1 lines are needed to make up a T3 line, we divide the T3 transmission rate by the T1 transmission rate:

A T3 line consists of multiple T1 lines bundled together to form a higher bandwidth pipe. Specifically, a T3 line is composed of 28 T1 lines. Each T1 line has a capacity of 1.544 megabits per second (Mbps), so a T3 line, also known as a DS3, has a total bandwidth of 44.736 Mbps. This bandwidth supports a high number of simultaneous data, voice, or video transmissions, which makes T3 lines suitable for large businesses or Internet service providers that require substantial data transfer capabilities.
