N.Y. Comp. Codes R. & Regs. tit. 16, § 603.4 – Reporting requirements.

(a) The Director of the Office of Communications shall issue guidelines prescribing the format, content and reporting times (except where otherwise prescribed herein) of each of the reports required pursuant to this Part. The director's guidelines shall be reasonable, practical, give due consideration to the format of the reports utilized by the service providers in the operation of their business, and be subject to de novo review by the commission in the event of a dispute.
(b) Each report shall arrive at the commission office no later than 30 days following the end of the report period (or such shorter interval as may be reasonable and practical and agreed upon between the director of the communications division and the service provider).
(c) Unless otherwise specified by the director of the communications division, the following terms for service performance shall apply:
1. (1) Service providers with 500,000 or fewer access lines in service shall only report on customer trouble report rate.
2. (2) Service providers with over 500,000 access lines in service shall report on all of the service metrics of section 603.3 of this Part.
  (d)
3. (1) For all the service quality metrics subject to reporting under subdivision (c) of this section except customer trouble report rate and percent final trunk group blockages, whenever a performance measure is not at or better than the performance threshold for the current month and any two of the previous four months, a service provider shall automatically submit to the commission staff a service inquiry report, as defined in subdivision (e) of this section.
4. (2) For customer trouble report rate, a service provider shall automatically submit to the commission staff a service inquiry report whenever an individual central office entity experiences 5.5 reports per 100 lines or greater for the current month and any two of the previous four months, or if a service provider has seven or more central offices and less than 85 percent of its central office entities experience 3.3 reports per 100 lines or less for the current month and any two of the previous four months.
5. (3) For percent final trunk group blockages, a service inquiry report shall automatically be filed whenever performance is not at or better than 3.0 percent for three consecutive months.
6. (4) In addition, commission staff may request a service inquiry report where deemed appropriate.
(e) A service inquiry report means a report which provides an explanation for the condition giving rise to the report, where readily determinable, and the number of consumers affected. It shall further include plans for corrective action including expectations of restoring service to adequate levels, or an explanation of why the corrective action details do not apply in this specific instance. The report shall be filed within 21 calendar days of a qualifying event as defined in subdivision (d) of this section. Addenda will be made to the report as necessary if the reporting service provider identifies important additional information and/or substantially modifies its corrective action plan as described in the report.
(f) A service provider may request an exemption from any or all of the reporting requirements of this section, if that provider can demonstrate that the services are provided through the resale of another service provider's tariffed services or purchase of another service provider's unbundled network elements (UNEs) over which it has no direct control. The director of the office of communications will grant or deny such exemption requests on a case-by-case basis.
