What is a primary characteristic of G.711 in fax technology?

• A. It's designed for high-speed data
• B. It compresses images for faster transmission
• C. It allows for real-time audio transmission
• D. It's obsolete in modern faxing

Answer: (C)

G.711 is primarily known as an audio codec used in telecommunications, specifically for VoIP (Voice over Internet Protocol) systems. One of its main features is that it allows for real-time audio transmission. This characteristic makes it suitable for applications where immediate delivery of audio is critical, such as voice calls. Although G.711 can technically be used in systems that handle fax, its primary purpose and strength lie in the clear and uncompressed handling of audio signals, thus ensuring low latency and high-quality audio during transmission. In the context of fax technology, while there are specific protocols and standards that handle fax transmissions more effectively (like T.38), G.711 can still be utilized in a voice path to transmit fax data. However, what distinguishes G.711 from other options is its focus on audio and real-time communication rather than data compression or high-speed data transfer, making it more relevant in scenarios that prioritize immediate audio over other functionalities.
