Which of the following is NOT an outage location?

The correct answer is modulation. Outage locations refer to specific points in a network where signals can be interrupted, affecting service delivery. In the context of broadband and cable systems, key outage locations typically include nodes or amplifier locations (Node/AMP), where signals are amplified for distribution, and headends, which are facilities used to receive and process television and internet signals for distribution.

In contrast, modulation is a process used in telecommunications to encode data onto carrier waves for transmission. While modulation is critical in determining how signals are created and transmitted, it does not represent a physical point in the network where an outage can occur. Instead, it describes a technique or method used within the systems that can still operate despite issues at outage locations like nodes or headends. Understanding the distinction between physical outage locations and technical processes is key for field technicians as they troubleshoot and maintain the network.
