Since multiple
11、 OCNs and/or Company Codes may be associated with a given company, companies with prior assignments should direct questions regarding appropriate OCN usage to the iconectiv Telecom Routing Administration (TRA) (; 866-672-6997). Pooling Administrator (PA) The term Pooling Administrator refers to the
12、entity or entities responsible for administering a thousands-block number pool (FCC 00-104 52.7 (g). The Pooling Administrator is responsible for the neutral administration of thousands-blocks from Central Office (CO) Codes in areas where thousands-block number pooling has been ordered or implemente
13、d. The PA is an impartial non-governmental entity that is not aligned with any particular telecommunications industry segment and is under contract to the FCC. Public Switched Telephone Network (PSTN) The PSTN is composed of all transmission and switching facilities and signal processors supplied an
14、d operated by all telecommunications common carriers for use by the public. Every station on the PSTN is capable of being accessed from every other station on the PSTN via the use of NANP E.164 numbers. Rate Area Denotes the smallest geographic area used to distinguish rate boundaries. Rate Center R
15、ate Center is used for numbering resource applications and reports to associate telephone numbers with a geographic area, as defined by the relevant regulatory agency. A Rate Center is also a uniquely defined point (Vertical & Horizontal Coordinates) located within an exchange area from which mileag
16、e measurements are determined. These measurements can be used with the tariffs in the message rating processes. Reporting Carrier Refers to a telecommunications carrier that receives numbering resources from the NANPA, a Pooling Administrator or another telecommunications carrier. Page 16(47 CFR 52.
17、7 (f) (2).Reseller An SP which purchases facilities and/or services from another SP for resale. Also, see “Intermediate Numbers” above. Reserved Numbers Reserved numbers are numbers that are held by service providers at the request of specific end users or customers for their future use. Numbers hel
18、d for specific end users or customers for more than 180 calendar days shall not be classified as reserved numbers (47 CFR 52.7 (f) (1) (vi). Service Provider The term “service provider” refers to a telecommunications carrier or other entity that receives numbering resources from the NANPA, a Pooling
19、 Administrator or a telecommunications carrier for the purpose of providing or establishing telecommunications service (FCC 00-104 52.5 (i). Soft Dial Tone Numbers Numbers that permit restricted dialing, such as calling emergency services and sometimes receive incoming calls (FCC 00-104 33). See “Ad
20、ministrative Numbers” definition. Switching Entity An electromechanical, electronic, or digital system for connecting lines to lines, lines to trunks, or trunks to trunks for the purpose of originating/terminating PSTN calls. A single switching system may handle several Central Office (CO) codes. Te
21、mporary Local Directory Number (TLDN) A number dynamically assigned on a per call basis by the serving wireless service provider to a roaming subscriber for the purpose of incoming call setup. See “Administrative Numbers” definition. Test Number A TN assigned for inter- and intra-network testing pur
22、poses. See “Administrative Numbers” definition. Thousands-block A range of one thousand TNs within an NPA-NXX beginning with X000 and ending with X999, where X is a value from 0 to 9. Thousand-block (NXX-X) Number Pooling Thousands-block number pooling is a process by which the 10,000 numbers in a c
23、entral office code (NXX) are separated into ten sequential blocks of 1,000 numbers each (thousands-blocks), and allocated separately within a rate center (47 CFR 52.20 (a). Page 17Type 1 Interconnection Service Provider A wireless SP that utilizes Type 1 (trunk side with line treatment) interconnect
24、ion with another SPs end office switch. Wireless E911 ESRD/ESRK Number A 10-digit number used for the purpose of routing an E911 call to the appropriate Public Service Answering Point (PSAP) when that call is originating from wireless equipment. The Emergency Services Routing Digit (ESRD) identifies
25、 the cell site and sector of the call origination in a wireless call scenario. The Emergency Services Routing Key (ESRK) uniquely identifies the call in a given cell site/sector and correlates data that is provided to a PSAP by different paths, such as the voice path and the Automatic Location Ident
26、ification (ALI) data path. Both the ESRD and ESRK define a route to the proper PSAP. The ESRK alone, or the ESRD and/or Mobile Identification Number (MIN), is signaled to the PSAP where it can be used to retrieve from the ALI database, the mobile callers call-back number, position and the emergency service agencies (e.g., police, fire, medical, etc.) associated with the callers location. If a NANP TN is used as an ESRD or ESRK, this number cannot be assigned to a customer. See “Administrative Numbers” definition.
