Enterprise Voice, Video, and Messaging Policy Security Requirements Guide
Title
The LAN hardware supporting VVoIP services must provide redundancy to support command and control (C2) assured services and Fire and Emergency Services (FES) communications.
Description
<VulnDiscussion>Voice services in support of high-priority military command and control precedence must meet minimum requirements for reliability and survivability of the supporting infrastructure. Design requirements for networks supporting DOD VVoIP implementations are in the Unified Capabilities Requirements (UCR), specifying assured services supporting DOD IP-based voice services. The UCR defines LAN design requirements for redundancy of equipment and interconnections, minimum requirements...
Fix Text (Documentation Requirement)
Implement and document that the LAN hardware supporting VVoIP services provides redundancy to support C2 assured services and FES communications. Mandatory redundancy includes the following: - Dual Power Supplies - Each platform must have a minimum of two power supplies, and the loss of a single power supply will not cause any loss of functions within the chassis. - Dual Processors (Control Supervisors) - Each chassis must support dual control processors, and failure of any one processor will not cause any loss of functions within the chassis. - Termination Sparing - Each chassis must support a (N + 1) sparing capability minimally for available Ethernet modules used to terminate to an IP subscriber. - Protocol Redundancy - Each routing device must support protocols allowing for dynamic ...
