911, sometimes written 9-1-1, is an emergency telephone number for Argentina, Canada, the Dominican Republic, Jordan, Iraq, Mexico, Pakistan, Palau, Panama, the Philippines, Sint Maarten, the United States, and Uruguay, as well as the North American Numbering Plan (NANP), one of eight N11 codes. Like other emergency numbers around the world, this number is only intended for use in emergency circumstances. Using it for any other purpose is a crime in most jurisdictions. Penalties for abuse or misuse of 911 can range from probation or community service to fines and jail time. Offenders can also be ordered to undergo counseling and have their use of telephones restricted or suspended for a period time as a condition of probation.
Enhanced 911 is a system used in North America to automatically provide the caller's location to 911 dispatchers. 911 is the universal emergency telephone number in the region. In the European Union, a similar system exists known as E112 and known as eCall when called by a vehicle.
An emergency telephone number is a number that allows a caller to contact local emergency services for assistance. The emergency number differs from country to country; it is typically a three-digit number so that it can be easily remembered and dialed quickly. Some countries have a different emergency number for each of the different emergency services; these often differ only by the last digit.
999 is an official emergency telephone number in a number of countries which allows the caller to contact emergency services for emergency assistance. Countries and territories using the number include Bahrain, Bangladesh, Botswana, Eswatini, Ghana, Guernsey, Hong Kong, the Republic of Ireland, the Isle of Man, Jersey, Kenya, Macau, Malaysia, Mauritius, Poland, Qatar, Sudan, Saudi Arabia, Singapore, Trinidad and Tobago, Seychelles, Uganda, the United Arab Emirates, the United Kingdom, and Zimbabwe.
A telecommunications device for the deaf (TDD) is a teleprinter, an electronic device for text communication over a telephone line, that is designed for use by persons with hearing or speech difficulties. Other names for the device include teletypewriter (TTY), textphone, and minicom.
Operator assistance refers to service provided by a telephone operator to the calling party of a telephone call. This can include telephone calls made from pay phones, calls placed station-to-station, person-to-person, or collect, third-number calls, calls billed to credit cards, and certain international calls which cannot be dialed directly. The telephone operator may also be able to assist with determining what kind of technical difficulties are occurring on a phone line, to verify whether a line is busy, or left off the hook, or to break in on a live call to ask the caller to clear the line for an incoming call. The latter service is often utilized by emergency police. In addition, operators are often a first point of contact for the elderly wanting information on the current date and time.
A call box or callbox is a box containing a special-purpose direct line telephone or other telecommunications device which has been used by various industries and institutions as a way for employees or clients at a remote location to contact a central dispatch office.
A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut.
An N11 code is a three-digit dialing code used in abbreviated dialing in the North American Numbering Plan (NANP). The mnemonic N stands for the digits 2 through 9 and thus the syntax stands for the codes 211, 311, 411, 511, 611, 711, 811, and 911. These dialing codes provide access to special local services, such as 911 for emergency services, which is a facility mandated by law in the United States. The (FCC) in CC Docket 92-105, specified how the N11 codes of 211, 311, 511, 711 and 811 codes would be used for various types of public information under NANP.
A public-safety answering point (PSAP), sometimes called a public-safety access point, is a type of call center where the public's telephone calls for first responders are received and handled. It takes calls from any landline, mobile phone line, or VoIP line. It can also happen that when 112 is dialed in then a logic is implemented by mobile or network operators to route the call to the nearest police station. Such call centers exist in most countries to answer calls to an emergency telephone number. Trained telephone operators are also usually responsible for dispatching these emergency services. Most PSAPs are now capable of caller location for landline calls, and many can handle mobile phone locations as well, where the mobile phone company has a handset to location system. Some can also use voice broadcasting where outgoing voice mail can be sent to many phone numbers at once, in order to alert people to a local emergency such as a chemical spill.
000 Emergency, also known as Triple Zero or Triple 0, and sometimes stylised Triple Zero (000), is the primary national emergency telephone number in Australia and Australian External Territories. The Emergency Call Service is operated by Telstra, and overseen by the Australian Communications and Media Authority (ACMA), and is intended only for use in life-threatening or time-critical emergencies.
A video relay service (VRS), also sometimes known as a video interpreting service (VIS), is a video telecommunication service that allows deaf, hard-of-hearing, and speech-impaired (D-HOH-SI) individuals to communicate over video telephones and similar technologies with hearing people in real-time, via a sign language interpreter.
Clarke Schools for Hearing and Speech is a national nonprofit organization that specializes in educating children who are deaf or hard of hearing using listening and spoken language (oralism) through the assistance of hearing technology such as hearing aids and cochlear implants. Clarke's five campuses serve more than 1,000 students annually in Canton, Massachusetts, Jacksonville, Florida, New York City, Northampton, Massachusetts, and Bryn Mawr, Pennsylvania. Clarke is the first and largest organization of its kind in the U.S. Its Northampton campus was listed on the National Register of Historic Places in 2022.
A fire alarm box, fire alarm call box, or fire alarm pull box is a device used for notifying a fire department of a fire or a fire alarm activation. Typically installed on street corners or on the outside of commercial buildings in urban areas, they were the main means of summoning firefighters before the general availability of telephones. Fire Alarm Call Boxes are still widely used in many cities and towns.
Telephone interpreting connects human interpreters via telephone to individuals who wish to speak to each other but do not share a common language. The telephone interpreter converts the spoken language from one language to another, enabling listeners and speakers to understand each other. Interpretation over the telephone most often takes place in consecutive mode, which means that the interpreter waits until the speaker finishes an utterance before rendering the interpretation into the other language. As the use of the telephonic modality is increasing it is allowing users to access an interpreter immediately, regardless of time and location.
Next Generation 9-1-1 refers to an initiative aimed at updating the 911 service infrastructure in the United States and Canada to improve public emergency communications services in a growing wireless mobile society. In addition to calling 9-1-1 from a phone, it intends to enable the public to transmit text, images, video and data to the 9-1-1 center. The initiative also envisions additional types of emergency communications and data transfer. This NG9-1-1 infrastructure is intended to replace the current services over time. The National Emergency Number Association (NENA) first identified the need for NG9-1-1 in 2000, and started development actions in 2003, and is nearing full definition and standards for NG9-1-1. Since 2006, the US Department of Transportation (DOT) in the United States and the Canadian Radio-television and Telecommunications Commission (CRTC) in Canada have been leading their respective initiatives, which include research and development projects aimed at advancing NG9-1-1. On January 24, 2013, the CRTC announced the first step toward a Canadian implementation of NG9-1-1 and, in March 2016, began a consultation with the public to discuss what services should be offered, who will play a role in offering these services and how these services should be paid for. Several US states have implemented versions of NG9-1-1, as of October 2013.
Radio resource location services (LCS) protocol (RRLP) applies to GSM and UMTS Cellular Networks. It is used to exchange messages between a handset and an SMLC in order to provide geolocation information; e.g., in the case of emergency calls. The protocol was developed in order to fulfil the Wireless Enhanced 911 requirements in the United States. However, since the protocol does not require any authentication, and can be used outside of a voice call or SMS transfer, its use is not restricted to emergency calls and can be used by law enforcement to pinpoint the exact geolocation of the target's mobile phone. RRLP was first specified in 3GPP TS 04.31 - Location Services (LCS); Mobile Station (MS) - Serving Mobile Location Centre (SMLC); Radio Resource LCS Protocol (RRLP).
James Carlyle Marsters was a deaf orthodontist in Pasadena, California, who in 1964 helped invent the first teletypewriter device capable of being used with telephone lines. The device made communication by telephone possible for the deaf. Although Robert Weitbrecht did much of the actual design work, Marsters promoted the device's use.
Total conversation is an ITU standard of simultaneous video, voice and text service in telecommunications. Total conversation allows people in two or more locations to: (a) see each other, (b) hear each other, and (c) conduct a text interaction with each other, or choose to communicate with any combination of those three modes and to do so in real-time.
Emergency text messaging services are a technology that enables emergency call operators to receive text messages. Its use is encouraged for people with hearing impairment or who have trouble speaking; it can also be used for situations when calling may pose a safety risk, such as a home invasion or domestic abuse. Concerns mainly arise from the accessibility of such technologies as they are not universally applied and may be inconsistent; therefore, voice calls are generally preferred for its speed, accessibility, and clarity.
