What access technology is used by DOCSIS 1.0 for upstream data transmission?

• A. Frequency Division Multiple Access (FDMA)
• B. Time Division Multiple Access (TDMA)
• C. Code Division Multiple Access (CDMA)
• D. Carrier Sense Multiple Access (CSMA)

Answer: (B)

The access technology used by DOCSIS 1.0 for upstream data transmission is Time Division Multiple Access (TDMA). TDMA allows multiple users to share the same communication channel by dividing the time into distinct time slots. Each user is assigned a specific time slot during which they can transmit their data without interference from other users. In the context of DOCSIS 1.0, this method is particularly beneficial for upstream communication where bandwidth is limited and efficient use of the available resources is crucial. By employing TDMA, the system can effectively manage how various devices send their data back to the network while minimizing collisions and maximizing throughput. This makes TDMA a suitable choice for the upstream data needs of DOCSIS 1.0, ensuring reliable and orderly data transmission from multiple user devices in a shared environment.
