The Fire and Emergency Services (F&ES) communications over a site's private telephone system must route emergency calls as a priority call in a nonblocking manner.
An XCCDF Rule
Description
<VulnDiscussion>When calling the designated F&ES telephone number, the call must go through regardless of the state of other calls in the system. Emergency calls must be treated as a priority call by the system. For enterprise systems, the support for E911 by the Enterprise Local Session Controller (LSC) (or any remote LSC construct) is governed by Federal Communication Commission (FCC) rules, as well as other federal, state, and local law. The design and implementation of all telephone systems must include reasonable efforts to provide E911, even when the access connection to the Enterprise LSC is severed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
