treatment | |
| 01 |
|
Multiparty 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 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 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. | |

Station Level Rating - The "06"
digit pair is used when 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
party’s room number. When the originating switching system
does not receive the detailed 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 number (DN) is not accompanied by an
automatic room/account
identification. | |
| 07 |
|
Special Operator Handling Required
- calls generated from stations that require further operator
or Operator Services System screening 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 will be routed to a standard
intercept
message. | |

Automatic Identified Outward
Dialing (AIOD) - without AIOD, the billing number for a PBX is
the same as the 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 the AMA
record. | |

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 which 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 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

Code 24 identifies a toll free
service call that has been translated to a Plain Old Telephone
Service (POTS) routable number via the toll free database that
originated for any non-pay station. If the received toll free
number is not converted to a POTS number, the database returns
the received ANI code along with the received toll free
number. Thus, Code 24 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 been translated to a Plain Old Telephone
Service (POTS) routable number via the toll free database that
originated from any pay station, including inmate telephone
service. Specifically, ANI II digits 27, 29, and 70 will be
replaced with Code 25 under the above stated
condition. | |

| 27 |
|
Code 27 identifies a line connected
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. | |

| 29 |
|
Prison/Inmate Service - the ANI II
digit pair 29 is used to designate lines within a
confinement/detention facility that are intended for
inmate/detainee use and require outward call screening and
restriction (e.g., 0+ collect only service). A
confinement/detention facility may be defined as including,
but not limited to, Federal, State and/or Local prisons,
juvenile facilities, immigration and naturalization
confinement/detention facilities, etc., which are under the
administration of Federal, State, City, County, or other
Governmental agencies. Prison/Inmate Service lines will be
identified by the customer requesting such call screening and
restriction. In those cases where private paystations are
located in confinement/detention facilities, and the same call
restrictions applicable to Prison/Inmate Service required, the
ANI II digit for Prison/Inmate Service will apply if the line
is identified for Prison/Inmate Service by the
customer. | |

Intercept - where the capability is
provide to route intercept calls (either 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 manually placed in
trouble-busy state by Telco personnel
- 32
Intercept (regular) - for calls to recently changed or
disconnected numbers

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", 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. | |

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 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 customer’s class of service and the
service area of the call party. When these calls are routed to
the interexchange carrier via a combined WATS-POTS trunk
group, it is necessary to identify the WATS calls with the ANI
code "52". | |

| 60 |
|
TRS - ANI II digit pair 60
indicates that the associated call is a TRS call delivered to
a transport 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" digit 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 directory 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.
(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/wireless 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 the 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.) | |

TRS - ANI II digit pair 66
indicates that the associated call is a TRS call delivered to
a transport carrier from a TRS Provider, and that the call
originates from a hotel/motel. The transport carrier can use
this indication, along with other information (e.g., whether
the call was dialed 1+ or 0+) to determine the appropriate
billing arrangement (i.e., bill to room or alternate
bill). | |
| 67 |
|
TRS - ANI II digit pair 67
indicates that the associated call is a TRS call delivered to
a transport carrier from a TRS Provider and that the call
originated from a restricted line. Accordingly, sent paid
calls should not be allowed and additional screening, if
available, should be performed to determine the specific
restrictions and type of alternate billing
permitted. | |

|
Code 70 identifies a line connected
to a pay station (including both coin and coinless stations)
which does not use network provided coin control signaling. II
70 is used to identify this type pay station line irrespective
of whether the pay station is provided by a LEC or a non-LEC.
II 70 is transmitted from the originating end office on all
calls made from these
lines. | |
