Fix Recommendation

Implement and document that the LAN hardware supporting VVoIP services provides physically diverse pathways for redundant links supporting C2 assured services and FES communications.

Ensure each uplink supports the full bandwidth, and the appropriate routing protocol is configured for failover from one uplink to the other when a failure occurs. This applies to access layer elements connected to distribution layer elements and distribution elements connected to core layer elements. Run new cable, upgrade, or reroute as necessary.

Check Contents

If the system does not support a minimum of 96 instruments, this is not applicable.

Review site documentation to confirm the LAN hardware supporting VVoIP services provides physically diverse pathways for redundant links supporting C2 assured services and FES communications.

The inspection of uplink pathways may require inspecting cable plant drawings or tracing the physical cable path through the building.

If the LAN hardware supporting VVoIP services does not provides physically diverse pathways for redundant links supporting C2 assured services and FES communications, this is a finding.
