Which components are included in packet cable architecture 1.0?

Packet Cable Architecture 1.0 is designed for delivering voice, video, and data services over a broadband network using the DOCSIS (Data Over Cable Service Interface Specification) standard. The correct option highlights the specific components that form the backbone of this architecture.

The inclusion of HFC (Hybrid Fiber-Coaxial) is significant, as it represents the physical medium used in Cable TV and broadband services, facilitating the transmission of data from the service provider to the consumer. This technology combines fiber optic and coaxial cable functionalities, allowing for high-speed data transmission, which is crucial in the Packet Cable framework.

IP (Internet Protocol) is also a foundational element in packet-based networks as it governs how data packets are formatted, addressed, transmitted, and routed. In the context of Packet Cable, IP is employed to manage voice and video traffic efficiently over the data network.

PSTN (Public Switched Telephone Network) connects traditional telephone services with the digital world. Its inclusion reflects the need to integrate existing telephone services with new digital offerings, allowing users to maintain access to voice services through the packet cable system.

In combination, these components ensure that Packet Cable Architecture 1.0 provides a robust framework for delivering integrated telephony services along with high-speed internet
