Appendix B: Glossary of Call Center and CRM Acronyms and Definitions

Call center definitions and acronyms

ACD

See Automatic Call Distribution.

ACD Overflow

A system feature wherein a call waiting in queue for an answer resource is offered to other centers operated by the enterprise. In better implementations, the caller becomes queued at all sites waiting for the first appropriately skilled CSR in any of the locations to become available.

Advisory Tones

The dial tone, busy signal, and dialing signal heard when using a phone system.

Agent

A generic term applied to all people working within call centers. The term became associated with call centers because airlines were among the first large ACD users; the people on the phones were reservation agents.

Analog

A term applied to telephone transmissions wherein the voice signal is converted into an electrical signal nearly identical to the sound waves produced by the human voice. Signals in the telephone network are either analog or digital.

ANI

Automatic number identification. A sequence of digits at the beginning of a phone call that identifies the calling phone number. Central to CTI applications, ANI can be deciphered and used to link the call to information on the call or caller that is available in host or workgroup databases. Called ANI by long-distance carriers, it is CLID—calling line identification to local phone companies.

Answering Supervision

A signal returned from the Central Office (CO) to indicate the call has been answered at the distant end.

Applications Programming Interface (API)

The software interface between application programs and the interface to network services or program-to-program communications. Standardized APIs are critical for developing or writing applications, allowing developers to focus on the front end as opposed to protocols.

Application Service Provider (ASP)

An organization that provides software suites to companies on a usage fee basis, usually via VPNs or the Internet. The economic justification for this approach is that the using company does not have to develop or maintain an IT organization or the expertise requisite to support the complex software suite. The ASP business model is usually directed toward providing enterprise resource planning (ERP) software and customer relationship management (CRM) applications.

Area Code Allocation

A process associated with routing 800 calls among multiple contact centers where the area code of the caller is used to determine which center will receive the call attempt.

Automated Attendant

A device that answers and processes incoming calls, directing callers to options such as extension directories or allowing access to live operators or attendants.

Automatic Call Distribution

Also commonly referred to as ACD, it is a functionality available in some PBX systems designed to handle and manage large volumes of incoming calls. Typical applications include customer service desks, telemarketing operations, reservation systems, and so on. An ACD allows efficient distribution of calls to available operators or voice processing options such as voice mail.

Average Speed of Answer (ASA)

One of the earliest metrics associated with handling telephone calls. ASA has slowly lost favor as the top metric for service level because averages tend to disguise the queue times that a significant, usually a minority, of callers actually experience.

Basic Rate Interface

A circuit that provides the user with two bearer (B) channels and one data (D) channel and is referred to as 2B+D. The bandwidth allocation is two 64,000-bits-per-second channels and one 16,000-bits-per-second data channel for signaling.

Call Accounting

Used to gather and monitor information about all telephone calling patterns, particularly long distance. Also monitors incoming calls. Usually a computer-based system linked to a telephone system.

Call Center

The location for centralized calling (inbound or outbound) or call reception activity. Staffed by CSRs, the call center usually involves an ACD linked to customer databases for order entry and so forth.

Call Control

Signals used to start or set up a phone call as well as to monitor and terminate (tear down) phone calls.

Call Processing

Activities related to starting, connecting, monitoring, or disconnecting phone calls. Pre-CTI, these functions were normally provided by the PBX and central office equipment.

Caller ID

A telephone service that provides the telephone number of the party placing a call to the called party.

Central Office or CO

The name given to the local telephone company's servicing exchange or "office"; usually where the big switches are located.

Centrex

A telephone system usually supplied by the local telephone company. The switching equipment is located in the telephone company central office. The only equipment at the customer premises is the telephones. One of the attractions of Centrex systems is that the system is rented rather than owned.

Circuit Switching

A methodology for moving digital and analog information wherein computer-controlled switching equipment is instructed to set up a continuous connection from the sender to the receiver. This connection remains in place even when no bits are being transmitted. Circuit switching is the technology upon which the existing telephone system is built. It is the opposite of packet switching.

CLID

Calling line identification.

Client/Server Architecture

Information technology in which the client (PC or workstation) requests information from a server. Servers may provide the user interface and perform some or all of the application processing. The server maintains databases and processes requests from the various clients to extract data from or to update the database.

CODEC

A word derived from the words code and decode referring to a solid-state device that digitizes human analog voice waveforms into bit streams and then back into analog voice waveforms.

Conditional Transaction Routing

A functionality in transaction routing whereby the system can access a set of real-time variables concerning the system, application, and CSR conditions. These variables are tested, and depending on the outcome of the test, different actions are taken.

Contact Center

A term increasingly being applied to multimedia-enabled call centers, which are evolved call centers that integrate the Internet into their operations. Typically, contact centers include text chat, e-mail handling, Website support technologies, and self-help devices that operate in the voice and Web environments.

Contention

A situation in which several phones or devices are attempting to access the same line. Telephone systems establish protocols (first-in, first-off, etc.) to establish connection and inform other callers of call status (busy signal).

CPE

Customer premise equipment; sometimes referred to as "customer provided equipment" to identify equipment on the premises owned by the customer.

CSR

Customer service representative; also referred to as an agent.

CTI

Computer telephony integration. The process, by which a telephone switch passes certain call information to a computer, allowing the computer to manage the call based on commands from a software application. Also refers to the process of using an adjunct computer to provide number crunching or database-intensive activities for the host PBX.

Custom Local Area Signaling Service (CLASS)

Services received from a local telephone company such as CLID. Other CLASS services could include distinctive ringing, call waiting, selective call forwarding, and selective call screening.

See also ANI.

Data-Directed Routing

The process of routing a caller based on information that exists about that caller within enterprise databases. For example, a contact center might wish to route calls from its best customers to selected CSRs ahead of other callers.

Dense Wavelength Division Multiplexing (DWDM)

A fiber-optic technology in which each fiber strand is actually divided into the individual wavelengths of light that make up white light. In this way, each wavelength of light on each strand can carry its own data stream.

Dialed Number Identification Service (DNIS)

An interexchange carrier service offering in which typically the last four numbers dialed by the calling party are transmitted to the ACD to help identify what kind of transaction the caller requires. DNIS is fundamentally similar to direct inward dialing (DID), a feature commonly found in private branch exchanges (PBX).

Digital

A device that uses binary code to represent information. In the world of telephony, this term refers to the encoding of an analog voice waveform into digital values represented by bits. The advantage of digital transmission over analog transmission is greater fidelity and resistance to noise.

E-mail Auto Response

This function involves receiving a customer's e-mail message and providing responses, usually prewritten, based on a software routine's analysis of the message content.

Erlang

A Danish engineer who more than 100 years ago created several statistical tables that are still used today to calculate the number of trunks needed to handle calling demand, expressed in hours and the number of agents required to meet a particular service-level goal. The two tables most frequently used are Erlang B (used for trunk calculation) and Erlang C (used for CSR staffing and scheduling).

Ethernet
