LERG Routing Guide
The LERG (Local Exchange Routing Guide) Routing Guide is a centralized reference used in telecommunications to facilitate the effective routing of calls between different telephone exchanges. It serves as an essential tool for both service providers and carriers to understand how calls should be routed across various networks. Key features and components of the LERG include: 1. **Routing Information**: It provides detailed information about the geographic areas served by different Local Exchange Carriers (LECs) and the numbering resources assigned to them.
Linked numbering scheme
A linked numbering scheme is a method used in various contexts, including document formatting, project management, and data organization, to create a systematic way of numbering items that are connected or related to one another. This scheme is particularly useful for maintaining order and clarity in lists, outlines, and hierarchical structures. Here are a few key characteristics and applications of a linked numbering scheme: 1. **Hierarchical Structure**: In documents, linked numbering often represents nested lists or sections.
List of country calling codes
A country calling code is a numeric prefix that must be dialed before the national phone number when making a call to a different country. Each country is assigned its unique calling code, which usually starts with a plus sign (+) when written in international formats.
An international call prefix is a code used to initiate an international telephone call from one country to another. This prefix is a specific number that must be dialed before the country code of the nation you are calling. Different countries have different international call prefixes.
The list of mobile telephone prefixes by country includes the codes assigned to mobile networks within each country. These prefixes are typically used as part of the mobile phone numbers. Here are some examples of mobile prefixes by country: - **United States**: Mobile numbers generally use the area codes (e.g., 410, 202, 323, etc.). The specific prefix for mobile networks can vary by carrier but includes numbers like 410-3XX, 202-4XX, etc.
Local number portability
Local Number Portability (LNP) is a telecommunications feature that allows individuals and businesses to retain their existing telephone numbers when they switch service providers within the same geographic area. This means that customers can change their phone service provider without the inconvenience of changing their phone number, which helps to promote competition among service providers and enhance customer choice. The process typically involves the following steps: 1. **Request to Port**: The customer requests to port their number to a new service provider.
Softening point
The softening point, also known as the softening temperature, is a specific temperature at which a material transitions from a hard or rigid state to a softer, more pliable state. This property is especially important for thermoplastic materials, such as certain types of plastics and some types of asphalt.
Sulaibiya
Sulaibiya is a district located in Kuwait, situated in the western part of the country. It is part of the Greater Kuwait area and is known for its residential communities, schools, and various facilities. Like many districts in Kuwait, Sulaibiya has experienced significant development in recent years, making it a popular area for residents. The district is characterized by a mix of modern infrastructure and traditional influences, reflecting Kuwait's cultural heritage.
Temperature-sensitive mutant
A temperature-sensitive (ts) mutant is a type of mutant organism, typically a bacterium, yeast, or animal cell, that exhibits a normal phenotype at a permissive temperature but displays a different phenotype, often a phenotype related to loss of function, at a non-permissive temperature. This change in phenotype is usually due to alterations in protein structure or function caused by mutations in the genes coding for those proteins. Temperature-sensitive mutants are particularly useful in genetic research and developmental biology.
Police perjury
Police perjury refers to the act of a police officer willfully lying or providing false testimony while under oath, typically during legal proceedings such as court trials or depositions. This misconduct undermines the integrity of the judicial system, as officers are expected to provide truthful and accurate information based on their observations and experiences in the field.
Random digit dialing
Random digit dialing (RDD) is a survey sampling technique used primarily for telephone research. It involves generating telephone numbers at random, including both listed and unlisted numbers, to ensure a representative sample of the population being studied. This method is particularly useful for telephone surveys where researchers want to gather opinions or data from a broad demographic without biasing the sample selection based on pre-existing lists of phone numbers.
Ringback number
A ringback number is a designated phone number that is used to play ringing sounds back to a caller while they wait for the recipient to answer. Instead of the traditional ringtone that the caller hears, this service allows the caller to hear music or another message until the recipient picks up the call. Ringback tones are often used for personalization and can include a variety of sounds, such as popular songs, jingles, or custom messages.
Shared-cost service
A **shared-cost service** refers to a type of service where the costs associated with providing that service are distributed among multiple parties or participants rather than borne by a single entity. This model is often used in various sectors to promote cost efficiency and make services more accessible.
Speaking clock
A speaking clock is a service that provides the current time audibly to callers. Typically, when a person dials a specific phone number, an automated voice responds and announces the current time. The service can be found in various countries and is often provided by telecommunications companies. Speaking clocks can be accessed through landline or mobile phones, and they may deliver the time in hours and minutes, sometimes including additional details like the day of the week or time zone.
Speed dial
Speed dial is a telephone feature that allows a user to quickly dial a specific phone number by pressing a designated button or a combination of buttons, instead of having to enter the full phone number manually. This feature is particularly useful for frequently called contacts, as it streamlines the dialing process. In traditional landline phones, speed dial typically involves assigning a single-digit number (often 2-9) to a specific phone number.
Subscriber trunk dialling
Subscriber Trunk Dialing (STD) is a telecommunications term used primarily in the UK and other countries to refer to the system that allows telephone subscribers to make long-distance calls without the need for an operator to assist them. This capability was first introduced in the 1950s and greatly simplified the process of making long-distance calls. In an STD system, callers can dial a prefix (often a trunk code) followed by the area code and the local number they wish to reach.
Fallen Dragon
"Fallen Dragon" is a science fiction novel by author Peter F. Hamilton, published in 2003. The story is set in a future where humanity has expanded into the galaxy and explores themes of corporate greed, sovereignty, and the consequences of technological advancements.
