Glossary

ACD (Automatic Call Distribution): A switching system designed to allocate incoming calls to certain
positions or agents in the order received and to hold calls not ready to be handled (often with a
recorded announcement).
Area Code: A 3-digit code used in North America to identify a specific geographic telephone location.
The first digit can be any number between 2 and 9. The second and third digits can be any number.
Billing Increment: The division by which the call is rounded. In the field it is common to see full-minute
billing on the local invoice while 6-second rounding is the choice of most long-distance providers that
bill their customers directly.
Blocked Calls: Caused by an insufficient network facility that does not have enough lines to allow
calls to reach a given destination. May also pertain to a call from an originating number that is
blocked by the receiving telephone number.
Bundled Service: Offering various services as a complete package.
Call Completion: The point at which a dialed number is answered.
Call Termination: The point at which a call is disconnected.
CDR (Call Detail Records): A software program attached to a VoIP/telephone system that records
information about the telephone number's activity.
Carrier's Carrier: Companies that build fiber optic and microwave networks primarily selling to
resellers and carriers. Their main focus is on the wholesale and not the retail market.
Casual Access: Casual Access is when customers choose not to use their primary carriers to process
the long-distance call being made. The customer dials the carrier's 101XXXX number.
CO (Central Office): Switching center for the local exchange carrier.
Centrex: This service is offered by the LEC to the end user. The feature-rich Centrex line offers the
same features and benefits as a PBX to a customer without the capital investment or maintenance
charges. The LEC charges a monthly fee to the customer, who must agree to sign a term agreement.
