§ 4.7 Definitions of metrics used to determine the general outage-reporting
threshold criteria.
Link to an amendment published at 77 FR 63757 , October 17, 2012.
(a) Administrative numbers are defined as the telephone numbers used by
communications providers to perform internal administrative or
operational functions necessary to maintain reasonable quality of
service standards.
(b) Assigned numbers are defined as the telephone numbers working in
the Public Switched Telephone Network under an agreement such as a
contract or tariff at the request of specific end users or customers
for their use. This excludes numbers that are not yet working but have
a service order pending.
(c) Assigned telephone number minutes are defined as the mathematical
result of multiplying the duration of an outage, expressed in minutes,
by the sum of the number of assigned numbers (defined in paragraph (b)
of this section) potentially affected by the outage and the number of
administrative numbers (defined in paragraph (a) of this section)
potentially affected by the outage. “Assigned telephone number minutes”
can alternatively be calculated as the mathematical result of
multiplying the duration of an outage, expressed in minutes, by the
number of working telephone numbers potentially affected by the outage,
where working telephone numbers are defined as the telephone numbers,
including DID numbers, working immediately prior to the outage.
(d) DS3 minutes are defined as the mathematical result of multiplying
the duration of an outage, expressed in minutes, by the number of
previously operating DS3 circuits that were affected by the outage.
(e) User minutes are defined as:
(1) Assigned telephone number minutes (as defined in paragraph (c) of
this section), for telephony, including non-mobile interconnected VoIP
telephony, and for those paging networks in which each individual user
is assigned a telephone number;
(2) The mathematical result of multiplying the duration of an outage,
expressed in minutes, by the number of end users potentially affected
by the outage, for all other forms of communications. For wireless
service providers and interconnected VoIP service providers to mobile
users, the number of potentially affected users should be determined by
multiplying the simultaneous call capacity of the affected equipment by
a concentration ratio of 8.
(f) Working telephone numbers are defined to be the sum of all
telephone numbers that can originate, or terminate telecommunications.
This includes, for example, all working telephone numbers on the
customer's side of a PBX, or Centrex, or similar arrangement.
[ 69 FR 70338 , Dec. 3, 2004, as amended at 77 FR 25097 , Apr. 27, 2012]
Effective Date Note: At 77 FR 25097 , Apr. 27, 2012, § 4.7 was amended
by revising paragraphs (e)(1) and (2). These paragraphs contain
information collection and recordkeeping requirements and will not
become effective until approval has been given by the Office of
Management and Budget.
