Using the Correct Ethernet Standard

Which Ethernet standard uses pins 4 and 5 for data transmission and reception?

a) pots, b)10baseT, c) 568A, d) 568B

Answer:

The technician's configuration of punching down only pins 4 and 5 corresponds to the 10baseT Ethernet standard, making the answer b) 10baseT correct.

When a technician punches down only pins 4 and 5 on an Ethernet patch panel, they are configuring the port to be used with the 10baseT Ethernet standard. This standard utilizes these specific pins for transmitting and receiving data signals, allowing for a basic Ethernet connection at a speed of 10 megabits per second (Mbps).

The 10baseT Ethernet standard utilizes a twisted-pair cable with four pairs of wires, but for a basic connection, only two pairs are required. Pins 1, 2, 3, and 6 are typically used for transmitting and receiving data, with pins 4 and 5 specifically designated for this purpose in the 10baseT standard.

By setting up the port in this manner, the technician ensures compatibility with the 10baseT Ethernet standard, enabling a reliable and efficient data transmission and reception process. This standard is ideal for basic Ethernet connections with a speed of 10 Mbps.

In conclusion, the technician's decision to punch down only pins 4 and 5 aligns with the requirements of the 10baseT Ethernet standard, demonstrating a well-informed choice for establishing an effective Ethernet connection.
