12、 services, while maintaining the effective management of a finite resource. The assignment practices detailed in these CIC Assignment Guidelines apply to the assignment of CICs made directly by North American Numbering Plan Administration (NANPA) to a specific entity. (See Section 2.2 for CIC applic

13、ation procedures). Therefore, the maximum number of CICs an entity may be assigned under these CIC Assignment Guidelines pertains to the number of CICs the CIC Administrator may directly assign to that entity. Accordingly, codes obtained via means other than direct assignment by the NANPA are outsid

14、e the scope of these CIC Assignment Guidelines and hence, are not included in the maximum code assignment limits. The requirements specified in these CIC Assignment Guidelines will apply to all CICs (e.g., the access and usage requirements for retaining CICs) regardless of the manner through which a

15、n entity obtained a code. 1.2 Definition, Use and Background of CICs 1The Canadian Radio-television and Telecommunications Commission (CRTC) has approved the Canadian Adjunct to the INC Carrier Identification Code (CIC) Assignment Guidelines. Those are for the administration of CICs in Canada by the

16、 Canadian Numbering CIC Administrator (CNA). The latest version is available at http:/crtc.gc.ca/cisc/eng/cisf3fg.htm. 247 CFR 52.5 (j). Carrier Identification Code (CIC) Assignment Guidelines ATIS-0300050 April 28, 2017 _ CICs provide routing and billing information for TDM-based calls from end use

17、rs via trunk-side connections to interexchange carriers and other entities. Those entities connect their facilities to access providers facilities using several different access arrangements, the common ones being Feature Group B (FG B) and Feature Group D (FG D). Access providers are common carrier

18、s and connecting carriers that provide interconnection services between an entity and another provider of telecommunications services or interconnected VoIP services. CICs were introduced in 1981 as 2-digit codes then were expanded to 3-digit codes in 1983. At that time CICs were assigned from a sin

19、gle pool of numbers serving both FG B and FG D access. Initially, entities could be assigned up to a maximum of three CICs, a primary and two supplemental CICs. When it was recognized that the supply of 3-digit CICs would eventually exhaust, the industry developed a plan to expand the resource to 4

20、digits, i.e., CIC expansion. In 1989, when the 700th CIC was assigned, industry agreements limited assignments to one per entity to prevent exhaust before completion of CIC expansion. CIC expansion was planned for implementation in two phases. Phase 1 was completed on April 1, 1993, at which time FG

21、 B and FG D CICs were split into two separate assignment pools. In addition, the FG B resource was expanded from 3 to 4 digits. FG D CICs continued to be assigned in the 3-digit format until exhaust which signaled the start of Phase 2. Phase 2 of CIC expansion was completed on April 1, 1995 when FG

22、D CICs were expanded to 4 digits. Existing 3-digit FG D CICs were converted to 4 digits by prepending a “0” in front of the CIC. After Phase 1 but before Phase 2 CIC expansion, entities could, if requested, reserve a 4-digit FG D CIC that matched the assigned 4-digit FG B CIC, which would be assigne

23、d when 4-digit FG D CICs became available. These CIC Assignment Guidelines have been modified to reflect the completion of CIC expansion and the availability of 4-digit CICs. For the purposes of these CIC Assignment Guidelines, CICs are 4-digit numeric codes which are currently used to identify cust

24、omers who purchase Feature Group B (FG B) and/or Feature Group D (FG D) access services,3Billing and Collections Clearinghouses that provide third-party bill aggregation services on behalf of access purchasers.4These codes are primarily used for routing from the local exchange network to the access

25、purchaser and for billing between the LEC (Local Exchange Carrier) and the access purchaser. For interconnected VoIP providers, they are used for compensation purposes related to Universal Service Fund terminating and originating access.53For purposes of these CIC Assignment Guidelines “access servi

26、ces” includes the purchase of trunk access for FG B or D, and, in the case of FG B, translations access (where available). Although LECs are not formal “purchasers” of FG B or FG D access, these CIC Assignment Guidelines do not preclude LECs from being assigned CICs. 4CIC codes also are used by Bill

27、ing and Collection Clearinghouses to facilitate billing for smaller access purchasers that do not have direct agreements with the LECs for billing. Billing and Collections Clearinghouses are not access purchasers, but they do have direct agreements with the LECs for billing services and use a common

28、 CIC code to identify all of their customers usage for settlement purposes. 5See WC Docket No. 10-90 USF/ICC Transformation Orders 11-161 released 11/18/2011 and 11-189 released 12/23/2011. Carrier Identification Code (CIC) Assignment Guidelines ATIS-0300050 April 28, 2017 _ CICs referred to in thes

29、e CIC Assignment Guidelines are those assignable by the CIC Administrator. In addition to those CICs assignable by the CIC Administrator, there are 200 four digit CICs, numbers 9000-9199, designated for intranetwork use and are therefore unassignable. These CICs are 1) intended for intranetwork use

30、only, 2) not intended to be used between networks, 3) not intended to be dialable by end users as a CAC (defined in this section). Use of the 200 unassignable CICs is at the discretion of each network provider and will not place requirements on other network providers. CICs exist in the public domai

31、n, and as such, are a public resource. Assignment of a CIC to an entity in no way implies or infers ownership of the public resource by the entity. Consequently, the resource cannot be sold, brokered, bartered, or leased for a fee or other consideration. If a resource is sold, brokered, bartered or

32、leased for a fee, the resource is subject to reclamation by the CIC Administrator. The availability of CICs will be monitored by the CIC Administrator who will report on the continued assignment of this public resource on a regular basis to the FCC and the INC. In addition to the use of CICs by the

33、service providers for routing and/or billing of access, the CIC comprises part of the Carrier Access Code (CAC), a dialing sequence used by the general public to access a preferred provider of service. Specifically, the CAC can be in the following formats: For FG B, the CAC is in the format 950-XXXX

34、, where XXXX is the FG B CIC. For FG D, the CAC is dialed using a 7-digit format (101XXXX), where X = 0 through 9. 1.3 Definition of an Entity CICs are assigned to entities that: Purchase FGB or FGD access. Purchase FGB translation access. Are service providers. Are switchless resellers. Are Billing

35、 and Collections Clearinghouses. For purposes of these CIC Assignment Guidelines, an entity will be defined as follows: An entity is defined as a firm or group of firms under common ownership or control. Franchise operators are those individuals, groups, or firms granted the right or license to mark

36、et a companys goods or services in a particular area. As there is a commonalty of Carrier Identification Code (CIC) Assignment Guidelines ATIS-0300050 April 28, 2017 _ economic interest in marketing conditions normally imposed on a franchise operator by the franchiser, these industry guidelines trea

37、t the franchiser as the relevant entity and not each individual franchise operator. The franchiser is eligible for CICs assigned to an entity up to the maximum number as determined by these CIC Assignment Guidelines. The franchise operators operating under the common franchise may each use the CICs

38、under the guidance of the franchiser. On the assumption that franchise operators are operating in different territories, as may be dictated by the franchiser, no technical limitation on access service exists due to this CIC limit. 1.4 Administration of CICs and Semi-Annual CIC Usage Reporting The as

39、signment and management of the CIC resource will be administered by the North American Numbering Plan Administrator (NANPA). All access providers shall provide Access Provider CIC Reports to NANPA; all entities that are assigned CICs (including switchless resellers and interconnected VoIP service pr

40、oviders) shall provide Entity Access/Usage reports to NANPA; and Billing the other pool contains the four-digit FG D resource. The FG B CIC format provides a pool of 9,000 codes. (Note: Only 9000 four digit FG B CICs are available for assignment because switches do not differentiate between CICs in

41、the 0XXX and 1XXX ranges. If, in the future, changes in technology allow the distinction between 4 digit FG B CICs of the form 0XXX and 1XXX, separate assignment of those CICs will be considered). THE FG D CIC format provides for a pool of 10,000 codes. FG B and FG D assignments are made separately.

42、 Accordingly, an entity whose needs demand the use of FG B access only will be assigned a FG B CIC. Carrier Identification Code (CIC) Assignment Guidelines ATIS-0300050 April 28, 2017 _ 1.6 Four Digit FG B CICs Four-digit FG B assignments are made from a single specific 1000s block. The first 1000s

43、block from which four digit FG B CICs are assigned is the 5000s block, followed by the 6000s block. The selection of the 5000s and 6000s block permits matching assignments to four digit FG D codes. Subsequent assignments will be made from the remaining blocks of numbers which will be opened sequenti

44、ally, starting with the 2000s block, i.e., 2000, 3000, 4000, 7000, etc. Opening of subsequent thousand blocks is dependent solely upon the exhaust of the current available FG B CIC resource. The NANPA will monitor CIC assignments and usage and provide annual reports to the INC indicating the level o

45、f assignment and projecting the time of exhaust of the current pool of FG B CICs semi-annually or as requested based on the then current assignment rate. The NANPA will formally notify the industry 2-1/2 years prior to the need for the next 1000s block of FG B CICs. Actual assignment of the new FG B

46、 1000s block will begin six months before the projected exhaust of the current FG B CIC pool. The industry will review the need, in the future, to continue to restrict assignment of FG B CICs to specific 1000s blocks. The industry will determine if, when technically practicable, this restriction wil

47、l be lifted, and FG B four digit assignments will be available from the full range of (9,000) FG B CICs. 1.7 Four-Digit FG D CICs At the time FG D CICs were expanded to four digits, a permissive period was established which permitted the use of both the 10XXX and 101XXXX CAC dialing formats. During this permissive period, four-digit FG D CICs began to be assigned in the 5000 and 6000 number blocks.6
