Which communication technology offers integrated data services for voice, video, and data transmission?

Integrated Services Digital Network (ISDN) is the correct choice because it was specifically designed to provide a standard way to transmit voice, video, and data over traditional circuit-switched networks. ISDN facilitates the simultaneous transmission of multiple types of data, enabling seamless communication and multimedia applications.

One of its key features is the ability to establish a digital connection that can carry multiple channels, making it possible to support various services over a single line. This capability is essential for applications that require high-quality voice calls as well as video conferencing and data transfers, all at the same time. Because of these integrative services, ISDN becomes particularly valuable for businesses and organizations that rely on versatile communication solutions.

In contrast, the Public Switched Telephone Network primarily focuses on voice communication without the same level of integration for video and data. Asymmetric Digital Subscriber Line, while providing high-speed internet access, does not support voice and video transmission simultaneously in the same versatile manner. Local Area Network typically serves to connect computers within a limited area but does not inherently provide integrated services for voice and video communication like ISDN does.
