Introduction The following table lists and defines ANI Information Digits Codes which are assigned by the North American Numbering Plan Administration (NANPA) at the request of the Industry Numbering Committee (INC). The assi
17、gnment of ANI II Digits does not imply their ubiquitous availability. The availability of ANI II Digits should, therefore, be confirmed with any given service provider. 2. ANI Information Digits Codes DIGITS DESCRIPTION 00 Plain Old Telephone Service (POTS) - non-coin service requiring no special tr
18、eatment 01 Multi-party line (more than 2) - ANI cannot be provided on 4 or 8 party lines. The presence of this “01” code will cause an Operator Number Identification (ONI) function to be performed at the distant location. The ONI feature routes the call to a CAMA operator or to an Operator Services
19、System (OSS) for determination of the calling number. 02 ANI Failure - the originating switching system indicates (by the “02” code), to the receiving office that the calling station has not been identified. If the receiving switching system routes the call to a CAMA or Operator Services System, the
20、 calling number may be verbally obtained and manually recorded. If manual operator identification is not available, the receiving switching system (e.g., an interLATA carrier without operator capabilities) may reject the call. 03-05 Unassigned 06 Station Level Rating - The “06” digit pair is used wh
21、en the customer has subscribed to a class of service in order to be provided with real time billing information. For example, hotel/motels, served by PBXs, receive detailed billing information, including the calling partys room number. When the originating switching system does not receive the detai
22、led billing information, e.g., room number, this “06” code allows the call to be routed to an operator or operator services system to obtain complete billing information. The rating and/or billing information is then provided to the service subscriber. This code is used only when the directory numbe
23、r (DN) is not accompanied by an automatic room/account identification. ANI INFORMATION DIGITS CODES ATIS-0300064 September 18, 1998 Page 4 of 10 _ DIGITS DESCRIPTION 07 Special Operator Handling Required - calls generated from stations that require further operator or Operator Services System screen
24、ing are accompanied by the “07” code. The code is used to route the call to an operator or Operator Services System for further screening and to determine if the station has a denied-originating class of service or special routing/billing procedures. If the call is unauthorized, the calling party wi
25、ll be routed to a standard intercept message. 08-09 Unassigned 10 Not assignable - conflict with 10X test code 11 Unassigned 12-19 Not assignable - conflict with international outpulsing code 20 Automatic Identified Outward Dialing (AIOD) - without AIOD, the billing number for a PBX is the same as t
26、he PBX Directory Number (DN). With the AIOD feature, the originating line number within the PBX is provided for charging purposes. If the AIOD number is available when ANI is transmitted, code “00” is sent. If not, the PBX DN is sent with ANI code “20”. In either case, the AIOD number is included in
27、 the AMA record. 21-22 Unassigned 23 Coin or Non-Coin - on calls using database access, e.g., 800, ANI II 23 is used to indicate that the coin/non-coin status of the originating line cannot be positively distinguished for ANI purposes by the SSP. The ANI II pair 23 is substituted for the II pairs wh
28、ich would otherwise indicate that the non-coin status is known, i.e., 00, or when there is ANI failure. ANI II 23 may be substituted for a valid 2-digit ANI pair on 0-800 calls. In all other cases, ANI II 23 should not be substituted for a valid 2-digit ANI II pair which is forward to an SSP from an
29、 EAEO. Some of the situations in which the ANI II 23 may be sent: Calls from non-conforming end offices (CAMA or LAMA types) with combined coin/non-coin trunk groups. 0-800 Calls Type 1 Cellular Calls Calls from PBX Trunks Calls from Centrex Tie Lines ANI INFORMATION DIGITS CODES ATIS-0300064 Septem
30、ber 18, 1998 Page 5 of 10 _ DIGITS DESCRIPTION 24 Code 24 identifies a toll free service that has been translated to a Plain Old Telephone Service (POTS) routable number via the toll free data base that originated for any non-pay station. If the received toll free number is not converted to a POTS n
31、umber, the data base returns the received ANI code along with the received toll free number. Thus, this 24 code indicates that this is a toll free service call since that fact can no longer be recognized simply by examining the called address. 25 Code 25 identifies a toll free service call that has
32、been translated to a Plain Old Telephone Service (POTS) routable number via the toll free data base that originated from any pay station, including inmate telephone service. Specifically, ANI II digits 27, 29 and 70 will be replaced with Code 25. 26 Unassigned 27 Code 27 identifies a line connected
33、to a pay station which uses network provided coin control signaling. II 27 is used to identify this type of pay station line irrespective of whether the pay station is provided by a LEC or a non-LEC. II 27 is transmitted from the originating end office on all calls made from these lines. 28 Unassign
34、ed 29 Code 29 is used to identify lines serving a confinement/detention facility that are intended for inmate/detainee use and require outward call screening (e.g., 0+ collect only service). As per Sect. 276 (d) of the Telecom Act, inmate telephone service is considered to be included in the general
35、 category of payphone service. Accordingly, lines identified with ANI II 29 include both prison/inmate phones/payphones. ANI INFORMATION DIGITS CODES ATIS-0300064 September 18, 1998 Page 6 of 10 _ DIGITS DESCRIPTION 30-32 Intercept - where the capability is provided to route intercept calls (either
36、directly or after an announcement recycle) to an access tandem with an associated Telco Operator Services System, the following ANI codes should be used: 30 Intercept (blank) - for calls to unassigned directory number (DN) 31 Intercept (trouble) - for calls to directory numbers (DN) that have been m
37、anually placed in trouble-busy state by Telco personnel 32 Intercept (regular) - for calls to recently changed or disconnected numbers 33 Unassigned 34 Telco Operator Handled Call - after the Telco Operator Services System has handled a call for an IC, it may change the standard ANI digits to “34”,
38、before outpulsing the sequence to the IC, when the Telco performs all call handling functions, e.g., billing. The code tells the IC that the BOC has performed billing on the call and the IC only has to complete the call. 35-39 Unassigned 40-49 Unrestricted Use - locally determined by carrier 50-51 U
39、nassigned 52 Outward Wide Area Telecommunications Service (OUTWATS) - this service allows customers to make calls to a certain zone(s) or band(s) on a direct dialed basis for a flat monthly charge or for a charge based on accumulated usage. OUTWATS lines can dial station-to-station calls directly to
40、 points within the selected band(s) or zone(s). The LEC performs a screening function to determine the correct charging and routing for OUTWATS calls based on the customers class of service and the service area of the call party. When these calls are routed to the interexchange carrier via a combine
41、d WATS-POTS trunk group, it is necessary to identify the WATS calls with the ANI code “52”. 53-59 Unassigned ANI INFORMATION DIGITS CODES ATIS-0300064 September 18, 1998 Page 7 of 10 _ DIGITS DESCRIPTION 60 TRS - ANI II digit pair 60 indicates that the associated call is a TRS call delivered to a tr
42、ansport carrier from a TRS Provider and that the call originated from an unrestricted line (i.e., a line for which there are no billing restrictions). Accordingly, if no request for alternate billing is made, the call will be billed to the calling line. 61 Cellular/Wireless PCS (Type 1) - The “61” d
43、igit pair is to be forwarded to the interexchange carrier by the local exchange carrier for traffic originating from a cellular/wireless PCS carrier over type 1 trunks. (Note: ANI information accompanying digit pair “61” identifies only the originating cellular/wireless PCS system, not the mobile di
44、rectory placing the call. 62 Cellular/Wireless PCS (Type 2) - The “62” digit pair is to be forwarded to the interexchange carrier by the cellular/wireless PCS carrier when routing traffic over type 2 trunks through the local exchange carrier access tandem for delivery to the interexchange carrier. (
45、Note: ANI information accompanying digit pair “62” identifies the mobile directory number placing the call but does not necessarily identify the true call point of origin.) 63 Cellular/Wireless PCS (Roaming) - The “63” digit pair is to be forwarded to the interexchange carrier by the cellular/wirele
46、ss PCS subscriber “roaming” in another cellular/wireless PCS network, over type 2 trunks through the local exchange carrier access tandem for delivery to the interexchange carrier. (Note: Use of “63” signifies that the “called number” is used only for network routing and should not be disclosed to t
47、he cellular/wireless PCS subscriber. Also, ANI information accompanying digit pair “63” identifies the mobile directory number forwarding the call but does not necessarily identify the true forwarded-call point of origin.) 64-65 Unassigned 66 TRS - ANI II digit pair 66 indicates that the associated call is a TRS call delivered to a transp
