Section 4.9 - [Effective an indefinitely delayed date ] Outage reporting requirements-threshold criteria(a)Cable. All cable communications providers shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration that:(1) Potentially affects at least 900,000 user minutes of telephony service;(2) Affects at least 667 OC3 minutes; (3) Potentially affects any special offices and facilities (in accordance with paragraphs (a) through (d) of §4.5); or(4) Potentially affects a 911 special facility (as defined in § 4.5(e) ) or potentially affects a 988 special facility (as defined in § 4.5(f) ), in which case they also shall notify the affected facility in the manner described in paragraph (h) or (i) of this section, respectively. Not later than 72 hours after discovering the outage, the provider shall submit electronically an Initial Communications Outage Report to the Commission. Not later than 30 days after discovering the outage, the provider shall submit electronically a Final Communications Outage Report to the Commission. The Notification and the Initial and Final reports shall comply with all of the requirements of § 4.11 .(b)IXC or LEC tandem facilities. In the case of IXC or LEC tandem facilities, providers must, if technically possible, use real-time blocked calls to determine whether criteria for reporting an outage have been reached. Providers must report IXC and LEC tandem outages of at least 30 minutes duration in which at least 90,000 calls are blocked or at least 667 OC3-minutes are lost. For interoffice facilities which handle traffic in both directions and for which blocked call information is available in one direction only, the total number of blocked calls shall be estimated as twice the number of blocked calls determined for the available direction. Providers may use historic carried call load data for the same day(s) of the week and the same time(s) of day as the outage, and for a time interval not older than 90 days preceding the onset of the outage, to estimate blocked calls whenever it is not possible to obtain real-time blocked call counts. When using historic data, providers must report incidents where at least 30,000 calls would have been carried during a time interval with the same duration of the outage. (OC3 minutes are defined in paragraph (d) of §4.7.) Justification that such data accurately estimates the traffic that would have been carried at the time of the outage had the outage not occurred must be available on request. If carried call load data cannot be obtained through any of the methods described, for whatever reason, then the provider shall report the outage.(c)Satellite.(1) All satellite operators shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, of an outage of at least 30 minutes duration that manifests itself as a failure of any of the following key system elements: One or more satellite transponders, satellite beams, inter-satellite links, or entire satellites. In addition, all Mobile-Satellite Service ("MSS") satellite operators shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, of an outage of at least 30 minutes duration that manifests itself as a failure of any gateway earth station, except in the case where other earth stations at the gateway location are used to continue gateway operations within 30 minutes of the onset of the failure.(2) All satellite communications providers shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration that manifests itself as: (i) A loss of complete accessibility to at least one satellite or transponder;(ii) A loss of a satellite communications link that potentially affects at least 900,000 user-minutes (as defined in §4.7(d)) of either telephony service or paging service; or(iv) Potentially affecting a 911 special facility (as defined in § 4.5(e) ) or potentially affecting a 988 special facility (as defined in § 4.5(f) ), in which case the affected facility shall be notified in the manner described in paragraph (h) or (i) of this section, respectively.(3) Not later than 72 hours after discovering the outage, the operator and/or provider shall submit electronically an Initial Communications Outage Report to the Commission. Not later than thirty days after discovering the outage, the operator and/or provider shall submit electronically a Final Communications Outage Report to the Commission.(4) The Notification and the Initial and Final reports shall comply with all of the requirements of §4.11.(5) Excluded from these outage-reporting requirements are those satellites, satellite beams, inter-satellite links, MSS gateway earth stations, satellite networks, and transponders that are used exclusively for intra-corporate or intra-organizational private telecommunications networks, for the one-way distribution of video or audio programming, or for other non-covered services (that is, when they are never used to carry common carrier voice or paging communications).(d)Signaling system 7. Signaling System 7 (SS7) providers shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize an outage of at least 30 minutes duration that is manifested as the generation of at least 90,000 blocked calls based on real-time traffic data or at least 30,000 lost calls based on historic carried loads. In cases where a third-party SS7 provider cannot directly estimate the number of blocked calls, the third-party SS7 provider shall use 500,000 real-time lost MTP messages as a surrogate for 90,000 real-time blocked calls, or 167,000 lost MTP messages on a historical basis as a surrogate for 30,000 lost calls based on historic carried loads. Historic carried load data or the number of lost MTP messages on a historical basis shall be for the same day(s) of the week and the same time(s) of day as the outage, and for a time interval not older than 90 days preceding the onset of the outage. In situations where, for whatever reason, real-time and historic data are unavailable to the provider, even after a detailed investigation, the provider must determine the carried load based on data obtained in the time interval between the onset of the outage and the due date for the final report; this data must cover the same day of the week and the same time of day as the outage. If this cannot be done, for whatever reason, the outage must be reported. Justification that such data accurately estimates the traffic that would have been carried at the time of the outage had the outage not occurred must be available on request. Finally, whenever a pair of STPs serving any communications provider becomes isolated from a pair of interconnected STPs that serve any other communications provider, for at least 30 minutes duration, each of these communications providers shall submit electronically a Notification to the Commission within 120 minutes of discovering such outage. Not later than 72 hours after discovering the outage, the provider(s) shall submit electronically an Initial Communications Outage Report to the Commission. Not later than thirty days after discovering the outage, the provider(s) shall submit electronically a Final Communications Outage Report to the Commission. The Notification and the Initial and Final reports shall comply with all of the requirements of §4.11.(e)Wireless.(1) All wireless service providers shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration:(i) Of a Mobile Switching Center (MSC);(ii) That potentially affects at least 900,000 user minutes of either telephony and associated data (2nd generation or lower) service or paging service;(iii) That affects at least 667 OC3 minutes (as defined in §4.7); or(v) That potentially affects a 911 special facility (as defined in § 4.5(e) ) or potentially affects a 988 special facility (as defined in § 4.5(f) ), in which case they also shall notify the affected facility in the manner described in paragraph (h) or (i) of this section, respectively.(2) In determining the number of users potentially affected by a failure of a switch, a wireless provider must multiply the number of macro cell sites disabled in the outage by the average number of users served per site, which is calculated as the total number of users for the provider divided by the total number of the provider's macro cell sites.(3) For providers of paging service only, a notification must be submitted if the failure of a switch for at least 30 minutes duration potentially affects at least 900,000 user-minutes.(4) Not later than 72 hours after discovering the outage, the provider shall submit electronically an Initial Communications Outage Report to the Commission. Not later than 30 days after discovering the outage, the provider shall submit electronically a Final Communications Outage Report to the Commission.(5) The Notification and Initial and Final reports shall comply with the requirements of §4.11.(f)Wireline. All wireline communications providers shall submit electronically a Notification to the Commission within 120 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration that:(1) Potentially affects at least 900,000 user minutes of either telephony or paging;(2) Affects at least 667 OC3 minutes; (3) Potentially affects any special offices and facilities (in accordance with paragraphs (a) through (d) of §4.5); or(4) Potentially affects a 911 special facility (as defined in § 4.5(e) ) or potentially affects a 988 special facility (as defined in § 4.5(f) ), in which case they also shall notify the affected facility in the manner described in paragraph (h) or (i) of this section, respectively. Not later than 72 hours after discovering the outage, the provider shall submit electronically an Initial Communications Outage Report to the Commission. Not later than 30 days after discovering the outage, the provider shall submit electronically a Final Communications Outage Report to the Commission. The Notification and the Initial and Final reports shall comply with all of the requirements of § 4.11 .(g) Interconnected VoIP Service Providers.(1) All interconnected VoIP service providers shall submit electronically a Notification to the Commission:(i) Within 240 minutes of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration that potentially affects a 911 special facility (as defined in § 4.5(e) ) or potentially affects a 988 special facility (as defined in § 4.5(f) ), in which case they also shall notify the affected facility in the manner described in paragraph (h) or (i) of this section, respectively; or(ii) Within 24 hours of discovering that they have experienced on any facilities that they own, operate, lease, or otherwise utilize, an outage of at least 30 minutes duration: (A) That potentially affects at least 900,000 user minutes of interconnected VoIP service and results in complete loss of service; or(B) That potentially affects any special offices and facilities (in accordance with paragraphs §4.5(a) through (d)).(2) Not later than thirty days after discovering the outage, the provider shall submit electronically a Final Communications Outage Report to the Commission.
