|CPC (Calling Party Control)|
CPC is a form of signaling that allows the call receiving party to know when the calling party has hung up. It is generally in the form of an open loop disconnect. It is a very important feature especially when communicating with voicemail or similar systems that need to know when the calling party hangs up.
|CSMA/CD (Carrier Sense Multiple Access w|
The CSMA/CD is a network access technology that enables devices of Ethernet based LANs to check the channel for carrier availability before beginning to transmit data. A device transfers information in absence of a carrier. A collision occurs when two stations try to transmit at the same time and is resolved when a device transmits data after a random time interval.
|CSU/DSU (Channel Service Unit/Digital Se|
A CSU and a DSU combine to form a device that is an essential part of any T1 or T3 telecommunications line. A CSU forms a connection between a terminal and a digital line. The DSU has a diagnostic and protective role for the line.
|ALOC (Average Length of Call)|
(Also known as ACD â?? Average Call Duration) refers to the time spent from the moment a call is answered to the moment the call is ended. This does not include the time taken in dialing and connecting to a user.
|ANI (Automatic Number Identification)|
ANI is when the receiver of a call can identify the caller through the incoming billing number. Caller ID is an example of ANI.
|ASP (Application Service Provider)|
An Application Service Provider refers to a model where an application is hosted on a central facility. From there, it is provided to the users through a network using a subscription method.
|ATA (Analogue Telephone Adapter)|
ATA is a device used to connect a traditional phone to a computer in order to make phone calls over the Internet. Unlike a VoIP phone, it is not connected directly to the USB port and is more cost-effective
|ATM (Asynchronous Transfer Mode)|
ATM uses dedicated connections to transfer video, voice and data signals at speeds many times faster than those achieved by current technologies. ATM uses multiplexing, high speed broadband and reduced delay transport to accomplish this task.
A part of a bigger PBX or another telephone system, an attendant console is associated with specific lines or functions of the telephone network. This allows correct routing and management of calls made to the programmed numbers. Similarly, an attendant console can be configured to perform particular functions. Various models of attendant consoles are available to choose from. Some common features include call queuing, easy-to-use features, one-touch transfer and call forwarding.
Backbone refers to a central network that serves as the nerve of a network. It generally stretches across long geographical distances and consists of several nodes of smaller network connections. The backbone carries the maximum traffic in a network.
|Bad Frame Interpolation|
Bad Frame Interpolation is the process of negating the effects of packet loss or packet corruption on the call. The process interpolates corrupt or lost voice packets using the previous voice frames, and ensures that the voice quality is good in the transmission.
Bandwidth is the amount of data a network connection can carry in a given time duration. High bandwidths transfer more data causing faster connections. Bandwidth is usually measured in bits per second (bps) or kilobits per second (kbps).
The unit devised to measure the duration of a call. The billing increment is typically written in seconds.
Applications that log usage of services so customers can be billed appropriately are referred to as billing systems. In addition to tracking usage, billing systems also manage customer data and analysis.

IP PBX Essentials 180x150
|BLI (Busy Lamp Indicator)|
The telephone LED indicating the phone line currently in use.
|BSS (Base Station System/Subsystem)|
The portion of a GSM network that includes the base station, base station controller and transcoders (if used). The segment of Ku-band satellite service, provided by high powered satellites (or clusters of satellites) and established by the FCC, must be separated in orbit by 9 degrees. The frequencies of RF signals transmitted to and received from the BSS satellites are higher than those permitted for FSS satellites. The BSS transmission frequency from high-power satellites to satellite receivers has been established by the FCC between 12.2 - 12.7 GHz.
