Definition

Configuration file used by devices.

Companding technique commonly used in North America. µ-law is standardized as a 64-kbps codec in ITU-T G.711.

ITU-T companding standard used in the conversion between analog and digital signals in PCM systems. A-law is used primarily in European telephone networks and is similar to the North American µ-law standard.

Admission Confirm.

The calling number

Admission Request.

Bearer channel. In ISDN, a full-duplex, 64-kbps channel used to send user data.

The Calling Search Space defines what directory numbers and route patterns a given device can call. It is a grouping of partitions to look through when making a call. For example, assume there are several Partitions in a Calling Search Space named “Executive.” If a

Cisco IP Phone number is in the “Executive” Calling Search Space, then when initiating a call, it looks for the example “NYInternationalCall,” “NYLongDistance,” “NYLocalCall,” and “NY911” Partitions available to search through. A Cisco IP Phone number that has a “Guest” Calling Search Space, for example, might only be allowed to search through “NYLocalCall” and “NY911” Partitions, so that if the user tries to dial an international number, it won’t find a match and the call can’t be routed.

Call Control API. Used by Cisco IOS to handle VoIP call processing.

Cisco Connection Online (http://www.cisco.com). Provides the latest information on Cisco products, technical support information, and technical documentation.

Call Detail Record. Information about call origination, destination, and duration, used to create billing records.

Cisco system software that provides common functionality, scalability, and security for all products under the CiscoFusion architecture. Cisco IOS allows centralized, integrated, and automated installation and management of internetworks, while ensuring support for a wide variety of protocols, media, services, and platforms.

Cisco CallManager cluster. A logical grouping of several Cisco CallManager servers.

Call Management Records, also known as Diagnostic CDRs. Records that contain the count of bytes sent, packets sent, jitter, latency, dropped packets, and so on.

Coder-Decoder. A DSP software algorithm used to compress/decompress speech or audio signals.

Data channel. Full-duplex, 16-kbps (BRI) or 64-kbps (PRI) ISDN channel. Used for signaling and control.

Disengage Confirm.

Dynamic Host Configuration Protocol. Provides a mechanism for allocating IP addresses dynamically so that addresses can be reused when hosts no longer need them.

Directory Number. This is the phone number of an end device. It can be a number assigned to a Cisco IP Phone, a Cisco IP SoftPhone, fax
