§ 4.5 Definitions of outage, special offices and facilities, and 911
special facilities.
(a) Outage is defined as a significant degradation in the ability of an
end user to establish and maintain a channel of communications as a
result of failure or degradation in the performance of a communications
provider's network.
(b) Special offices and facilities are defined as major military
installations, key government facilities, nuclear power plants, and
those airports that are listed as current primary (PR), commercial
service (CM), and reliever (RL) airports in the FAA's National Plan of
Integrated Airports Systems (NPIAS) (as issued at least one calendar
year prior to the outage). The member agencies of the National
Communications System (NCS) will determine which of their locations are
"major military installations" and "key government facilities." 911
special facilities are addressed separately in paragraph (e) of this
section.
(c) All outages that potentially affect communications for at least 30
minutes with any airport that qualifies as a "special office and
facility" pursuant to the preceding paragraph shall be reported in
accordance with the provisions of § § 4.11 and 4.13.
(d) A mission-affecting outage is defined as an outage that is deemed
critical to national security/emergency preparedness (NS/EP) operations
of the affected facility by the National Communications System member
agency operating the affected facility.
(e) An outage that potentially affects a 911 special facility occurs
whenever:
(1) There is a loss of communications to PSAP(s) potentially affecting
at least 900,000 user-minutes and: The failure is neither at the
PSAP(s) nor on the premises of the PSAP(s); no reroute for all end
users was available; and the outage lasts 30 minutes or more; or
(2) There is a loss of 911 call processing capabilities in one or more
E-911 tandems/selective routers for at least 30 minutes duration; or
(3) One or more end-office or MSC switches or host/remote clusters is
isolated from 911 service for at least 30 minutes and potentially
affects at least 900,000 user-minutes; or
(4) There is a loss of ANI/ALI (associated name and location
information) and/or a failure of location determination equipment,
including Phase II equipment, for at least 30 minutes and potentially
affecting at least 900,000 user-minutes (provided that the ANI/ALI or
location determination equipment was then currently deployed and in
use, and the failure is neither at the PSAP(s) or on the premises of
the PSAP(s)).
