What command should be entered into the TDMA modem to display the bit error rate?

The command "Show_ber" is the appropriate choice for displaying the bit error rate on a TDMA modem. This command is standard in many command-line interfaces for various networking and telecommunications equipment. It directly correlates with the action of retrieving or presenting information, in this case, the bit error rate, which is a crucial metric in assessing the quality and reliability of a digital communication link.

The use of "Show" in this command aligns with common nomenclature used in technical commands, making it intuitive for operators who are accustomed to similar commands across various systems. Understanding this command is vital, as bit error rate is an essential parameter in monitoring the performance of communication systems, allowing technicians to diagnose issues and make necessary adjustments to improve signal integrity.

Other options may seem related, but they do not follow the established command patterns typically used in modem interfaces. This highlights the importance of familiarity with command syntax and terminology specific to TDMA modems.
