Telecom Infrastructure Standard for Data Centers: TIA-942Tier 3 – Concurrently Maintainable:99.982% AvailabilityTypical Commercial Data CenterTier 4 – Fault Tolerant: 99.995%AvailabilitySpecial construction Enables planned activity withoutdisrupting operation, unplannedevents can cause disruption Multiple power and cooling pathsbut only one active, includesredundant components (N 1) Reliability of parallel data centers:99.99999% availability (7 9’s) Planned activity does not disruptcritical elements. Can sustain atleast one worse-case unplannedevent with no critical load impact. Multiple active power and coolingdistribution paths. Two UPS withredundant components. Reliability of parallel data centers:99.999999% availability (8 9’s)Thursday June 6, 20135
Public Land Mobile Network ID (PLMN ID) FirstNet PLMN ID is 313-100 Ninety-nine more held on reserve at ATIS, can be obtained later– “313” is a Globally unique country code.Thank-you: DHS OEC, PSCR, and contractors SAIC & Dr. DevasirvathamDHS OEC to continue support until FirstNet has automated process Defines FirstNet uniquely across all States, territories, tribal areas.

Managed Trusted Internet Protocol Service (MTIPS): Internet Access Protected by best-in-class intrusion detection and preventionsystems Current and future standards compliance to strict IETF, NIST, andother industry requirements Best-in-class systems, 3rd generation Monitored by specialized security operations centers Requires specialized trained engineers Available through AT&T, Verizon, Sprint, CenturyLink FirstNet could build own MTIPS facilitiesThursday June 6, 201313
Local Control: Governance Network design and delivery SLAs with local entities that contain guarantees and penalties An unbiased process for dispute resolution must be in place (e.g.,Neutral 3rd party arbitration) Cell site selection Location and coverage rules Network topology Must support interconnection to existing PS data and applicationservices Must reuse existing local entity IP networks Must provide flexibility to reuse existing backhaul facilities* Base requirements: NPSTC Local Control documentThursday June 6, 201314
Local control: User and device management Subscription management Local entities must have ability to change, add or deletedevice subscription of all users in their span of control control of change event timing (i.e. so they don’t occur when thebars are closing) Device Procurement Local entity to choose any LTE device from NTIA list Local entity may bring their own device Device inventory controlled by local entityThursday June 6, 201315
Local Control: Network operations and maintenance Network monitoring Ability to view local network status – e.g., network faults Notification of local maintenance plans Ability to view local network utilization and congestion Control of scheduling for network maintenance Local entity must have autonomy to invoke dynamicQoS policies Pre-configure templates to account for different user/device priorityand preemption requirements of public safetyThursday June 6, 201316
