Final answer:
A T1 line carries 24 DSO channels, with each channel capable of transmitting data at a rate of 64 Kbps, resulting in a total bandwidth of 1.544 Mbps for the entire T1 line.
Step-by-step explanation:
A T1 line carries 24 DSO channels. The T1 line is a type of digital communication transmission that is widely used in North America and Japan. It is one of several T-carrier systems that were developed to support voice and data transmission over copper telephone lines. The T1 consists of 24 digital channels, and each of these channels is referred to as a Digital Signal 0 (DS0), with a capacity of 64 Kbps. Therefore, a full T1 line can carry 24 × 64 Kbps of data, equal to a total bandwidth of 1.544 Mbps.
