Upgraded Critically Assured Service (uCAS)

Title of Project: Upgraded Critically Assured Service (uCAS) for USARPAC EAC.

Introduction: The USARPAC Emergency Action Center (EAC) serves as the commands only persistent, 24/7 command and control node.  The EAC is responsible for receiving, processing, and disseminating flash traffic, Serious Incident Reports (SIR), and Commander’s Critical Information Requirements (CCIR).  As the only such node, the EAC cannot tolerate any service interruption. 

Objectives of Requirements: The EAC must possess assured service techniques that allow uninterrupted inbound and outbound telephone calls.  These techniques ensure that normal features and functions are not degraded or lost

Specific Scope of the Requirement.

            a. uCAS must extend to the EAC operating spaces within Bldg T-113 and the Command and Control Facility (C2F) and allow the EAC to receive and transmit telephone calls without interruption. 

            b. The network shall automatically sense and reroute incoming/outgoing calls during subtending central office, link or access line outages and provide class of service and features authorized to the subscribers assigned telephone number.

            c. The system shall automatically reset to the default configuration when the subtending central office, link or access line has been restored.

            d. Call manage cluster in geo-diverse locations.  If one site fails, telephone automatically registers to another location.

            e. Precedence dialing.  During emergencies, EAC inbound and outbound telephone calls will have higher precedence than other telephone calls within the system.

            f. A total of three lines within the USARPAC EAC will have the uCAS capabilities.

            g.  Roll over features.  If a member of the EAC is on a line and another user within the system is attempting to call the number, the telephone call will roll over to one of the other two lines possessing uCAS features.

            h.  Rapid Maintenance Response.  The uCAS shall include a rapid response requirement so that if the system is non-functioning for two hours a staffed call center with remote maintenance capabilities shall respond.  If the call center is unable to correct the deficiency, then a physical response to the site is required within four hours.
