Call Gapping is a

load control Load management, also known as demand-side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. This can be ach ...

telephone traffic A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into ele ...

telephone network A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more ...

to particular destinations. It is used to protect switches against call processing overload. There are a number of algorithms available to achieve this. * Crawford gapping works by blocking calls for a determined period of time (the gap size). After the period of time passes, another call is allowed through. Another gap is then started and the process repeats until the overload condition is resolved. *

Leaky Bucket The leaky bucket is an algorithm based on an analogy of how a bucket with a constant leak will overflow if either the average rate at which water is poured in exceeds the rate at which the bucket leaks or if more water than the capacity of t ...

gapping creates a queue into which new call attempts are placed. Calls are handled from this queue at a pre-defined rate. Any new calls arriving at a full queue are rejected. * Proportional Bidding rejects a pre-defined percentage of call attempts. For a rejected call, an announcement may be played. Call gapping is not to be confused with

Silence suppression The term silence suppression is used in telephony to describe the process of not transmitting information over the network when one of the parties involved in a telephone call is not speaking, thereby reducing bandwidth usage. Voice is carried ove ...
