Which component of the TSC is responsible for handling VoIP subscribers?

The Local Session Controller is essential for managing VoIP subscribers because it serves as a gateway that facilitates communication between various network elements. This component plays a crucial role in session management, signaling, and call setup for VoIP services. By establishing and maintaining the necessary sessions for VoIP traffic, the Local Session Controller ensures that calls can be appropriately routed and managed, providing a seamless communication experience for subscribers.

In contrast, the Ethernet switch operates at a lower network layer, focusing on data forwarding based on MAC addresses, while the Rectifier Shelf and Uninterruptible Power Supply are hardware components related to power management and do not directly engage in handling VoIP subscriber sessions. Therefore, the Local Session Controller is the designated component for managing the specific requirements and functionalities of VoIP interactions.
