Calling Cards Glossary
Calling cards are an every day commodity. Often times the phone companies confuse their service with new words or technical jargon. The average calling card user has no concept of what all these terms mean. We decided that we provide you this helpful resource in case you encounter an unknown glossary term in the calling card industry.

If you can not find a term that you are looking for, please e-mail us and we will try to help you with your new term(s). We encourage this as it helps other users. Our goal is for you to become a knowledgeable consumer in purchasing a calling card.
Access gateway Equipment used to provide the electronic "bridge" from the public switched telephone network (PSTN) to an Internet protocol (IP) network.
Account Codes Also known as Project Codes or Bill-Back Codes. Account Codes are additional digits dialed by the calling party that provide information about the call. Typically used by hourly professionals (accountants, lawyers, etc.) to track and bill clients, projects, etc.
Agent A person or organization that acts on behalf of another. In the telecommunications industry, Agents typically are independent individuals or companies that market the services of a carrier as if they were employees of that carrier.
Alternate Access A form of local access where the provider is not the LEC, but is authorized or permitted to provide such service.
Alternate Access Carriers Local exchange carriers in direct competition with the RBOCs. Normally found only in the larger metropolitan areas. Examples are Teleport and Metropolitan Fiber Systems.
Alternative Operator Services Operator services provided by a company other than a LECRBOC or AT&T that is authorized to provide such service.
ANI See Automatic Number Identification.
Authentication Process of verifying with certainty the identity of a valid subscriber or ITSP through the use of a unique user identification number, password or other method (i.e., verifying that customers are who they say they are).
Authorization Process of allowing a Subscriber or ITSP a certain monetary credit or time amount of IP Telephony. Authorization is the granting of permission to provide users the service they are requesting.
Authorization Number same as PIN.
Automatic Number Identification Originating Number
(1) The number associated with the telephone station(s) from which switched calls are originated (or terminated).
(2) A software feature associated with Feature Group D (and optional on Feature Group B) circuits. ANI provides the originating local telephone number of the calling party. This information is transmitted as part of the digit stream in the signalling protocol, and included in the Call Detail Record for billing purposes.
(3) ANI may also be used to refer to any phone number.
BAN - Billing Account Number Used by telephone companies to designate a billing account, i.e., a customer or customer location that receives a bill. A customer may have any number of BANs.
Banded Rates Tariffed rates which may be changed by the carrier within a specified range. Frequently, state commissions require notice to the commission prior to each change. Banded rates are being used less frequently today.
Billing Account Number - BAN Used by telephone companies to designate a customer or customer location that will be billed. A single customer may have multiple billing accounts.
Bill-To-Room A billing option associated with Operator Assisted calls that allows the calling party to bill a call to their hotel room. With this option, the carrier is required to notify the hotel, upon completion of the call, of the time and charges.
Bong An interactive signal that prompts the originating end user to enter additional information. For example: 1010555 Bong (Enter Destination) Bong (Enter Billing information)
Also used to denote a sucharge particularly in the calling card industry.
BTN - Billing Telephone Number The phone number associated, for billing purposes, with the Working Phone Number.

Call Data Record (CDR) Record of a placed call. A CDR includes the time the call was placed and the duration of the call.
Calling Cards Telecommunication credit cards with an AuthCode for using a long distance carrier when the customer is away from their home or office (ANI).
Callingcards Same as calling cards or calling cards.
Carrier A telecommunications provider which owns switch equipment.
Carrier Identification Code - CIC A three digit number used with Feature Groups B and D to access a particular IEC's switched services from a local exchange line. One or more CIC codes are assigned to each carrier. (i.e. there may be multiple CICs per ACNA). See Bypass
Casual Calling Allow any ANI (including undefined ANIs) to access a given carrier. For example, if the originator is calling from a non-coin phone, they may dial 1010555+destination number and have the call routed through WorldCom and billed to the originating phone
Casual Customer Any person or organization that dials any CIC Code. (Not necessary to presubscribe to the carrier.)
Class of Service - COS A special limitation on what numbers can and cannot be called. International, 809, 809 + Canada, 48 contiguous states, etc.
Clipping Situation where the system cuts off the first part of the first word in a sentence. (Not to be confused with choppiness -- which is a packet loss).
COCOT Customer Owned Coin Operated Telephone
Coin Phone A coin-operated pay phone with restricted access to some services (e.g. International calling). Coin phones have subclasses of Public, Semi Public, and Private.
Collect A call that is paid for by the receiving/destination phone number. Requires approval/authorization of the person being called.
Common Carrier A carrier that holds itself out as serving the public (or a segment thereof) indifferently (i.e., without regard to the identity of the customer and without undue discrimination). Common carriers may vary rates based on special considerations and may in fact serve only a small fraction of the general public.
Connection Fee A fee charged on every call that is made.
Contract A legally-binding agreement between a vendor and a customer to provide Products, Services or Features in a specified quantity and quality, for a specified price, during a specified period of time.

DDI - Direct Dial In Designates a private number or direct line which either bypasses the switchboard/PABX or is available after hours.
Deactivation A request to terminate service (or the process of terminating service)
Default Carrier Your regular Dial-1 carrier. Call 1-700-555-4141 to find your default carrier.
Dial To Place A Call On A Switched Network. The term "dial" is obsolete - based on rotary dial phones and electromechanical relay switches (which are nearly non-existent in modern telephone systems.) Touch Tone service recognizes dual tones that are generated as each telephone key is pressed. Where Touch Tone service is not available, telephones and switches electronically "pulse" signals that emulate the older rotary dial telephones. The terms "place" a call or "originate" a call are more accurate than "dial".
Dial Tone Ready To Place/Originate A Call. When the off hook indication is received at a central office, a dial tone signal is sent to the originating caller on a switched network to indicate that the switch is ready to accept a number.
Dialer Equipment that pulses out a standard dial protocol signal.
Digital A device or method that uses discrete variations in voltage, frequency, amplitude, location, etc. to encode, process, or carry binary (zero or one) signals for sound, video, computer data or other information. For example, a digital clock displays the time as discrete numeric values, rather than angular displacement of analog hands. Digital communications technology generally permits higher speeds of transmission with a lower error rate than can be achieved with analog technology. When analog signals are received and amplified at each repeater station, any noise is also amplified. A digital signal, however, is detected and regenerated (not amplified). Unlike amplification, any noise (less than a valid signal) is eliminated by digital regeneration.
Directory Assistance - DA An information service whereby operators assist customers in obtaining the telephone number(s) they wish to call.
Equal Access (AT&T Divestiture - 1982 Modified Final Judgement) The provision of one-plus capability to interLATA competitors of AT&T. Customers should be able to reach the carrier of their choice by dialing 1+ the long-distance number. The MFJ and the FCC require local exchange carriers to provide equal access (most central offices now have this capability). Equal Access may also refer to a more generic concept under which the BOCs must provide access services to AT&T's competitors that are equivalent to those provided to AT&T.
