What is the maximum number of phases a dual ring can hold?

A dual ring can be understood as a topology that utilizes two distinct rings for distributing signals or power within a network. The number of phases a dual ring can support is based on its structural configuration and the need for effective signal integrity.

In this case, a dual ring configuration can maximally accommodate 8 phases. This is because each ring can effectively operate with an even number of phases to ensure balanced load distribution and to minimize the impact of interference within the system. By employing a dual setup, the network can handle complex signaling and ensure redundancy, enhancing reliability and fault tolerance.

The other options do not align with the operational design of dual rings as they suggest either fewer phases than supported or a higher count that exceeds practical implementation for optimal performance. Thus, 8 phases is the logical and technically feasible maximum for a dual ring configuration.
