Telecom Infrastructure Standard for Data Centers: TIA-942

Tier 3 – Concurrently Maintainable: 99.982% Availability

Typical Commercial Data Center

• Enables planned activity without disrupting operation, unplanned events can cause disruption

• Multiple power and cooling paths but only one active, includes redundant components (N+1)

• Reliability of parallel data centers: 99.99999% availability (7 9’s)

Tier 4 – Fault Tolerant: 99.995% Availability

Special construction

• Planned activity does not disrupt critical elements. Can sustain at least one worse-case unplanned event with no critical load impact.

• Multiple active power and cooling distribution paths. Two UPS with redundant components.

• Reliability of parallel data centers: 99.999999% availability (8 9’s)


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. Devasirvatham

− DHS OEC to continue support until FirstNet has automated process

• Defines FirstNet uniquely across all States, territories, tribal areas.

• IMSI: PLMN ID + Mobile Subscriber Identity (MSIN)

Network Security Requirements

• Assigning Impact Levels and Security Categorization

− NIST SP 800-60: two impact studies: 1. Nationwide Public Safety Broadband Network Cyber

Infrastructure Risk Assessment (CIRA) - DHS

2. NPSTC BBWG Security Task Group (STG)

• Next steps FIPS 200 / NIST SP 800-53

− Most likely, MOD/High Appendix F “Security control catalog”

• All third-party networks are in a separate security zones.

• US-CERT and DHS security consultants


Some third-party networks

* Four class of service (CoS) most common commercial design.


Managed Trusted Internet Protocol Service (MTIPS): Internet Access

• Protected by best-in-class intrusion detection and prevention

systems • Current and future standards compliance to strict IETF, NIST, and

other 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 facilities


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 application

services

• Must reuse existing local entity IP networks

• Must provide flexibility to reuse existing backhaul facilities

* Base requirements: NPSTC Local Control document


Local control: User and device management

• Subscription management • Local entities must have ability to change, add or delete

device subscription of all users in their span of control • control of change event timing (i.e. so they don’t occur when the

bars 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 entity


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 dynamic

QoS policies • Pre-configure templates to account for different user/device priority

and preemption requirements of public safety
