Carrier Ethernet Associate 2025 – 400 Free Practice Questions to Pass the Exam

The benefit of "Ethernet over PDH" lies in its ability to integrate Ethernet frames into existing traditional digital circuit infrastructure. By enabling this interoperability, organizations can leverage their existing PDH (Plesiochronous Digital Hierarchy) networks to transport Ethernet traffic without requiring a complete overhaul or replacement of their current systems.

This is particularly valuable for businesses that want to implement Ethernet services but are constrained by legacy infrastructure. The implementation facilitates a more gradual migration towards modern Ethernet networking while allowing for the continuation of service on existing PDH lines. This method maintains cost-effectiveness and efficiency in network management by maximizing current assets rather than necessitating new physical installations or substantial upgrades.

The other options do not align with the primary function of "Ethernet over PDH." Increasing the speed of fiber optics, simplifying wireless communications, or improving data encryption pertain to different aspects of networking technology and do not specifically relate to the benefits derived from integrating Ethernet over existing PDH infrastructures.
