Rotary Telephone
A rotary dial is a component of a telephone or a telephone switchboard that implements a signaling technology in telecommunications known as pulse dialing. It is used when initiating a telephone call to transmit the destination telephone number to a telephone exchange. On the rotary dial, the digits are arranged in a circular layout, with one finger hole in the finger wheel for each digit. For dialing a digit, the wheel is rotated against spring tension with one finger positioned in the corresponding hole, pulling the wheel with the finger to a stop position given by a mechanical barrier, the finger stop. When released at the finger stop, the wheel returns to its home position driven by the spring at a speed regulated by a governor device. During this return rotation, an electrical switch interrupts the direct current (DC) of the telephone line (local loop) the specific number of times associated with each digit and thereby generates electrical pulses which the telephone exchang ...

Pager
A pager (also known as a beeper or bleeper) is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to and originate messages using an internal transmitter. Pagers operate as part of a paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations), as well as a number of pagers carried by mobile users. These systems can range from a restaurant system with a single low power transmitter, to a nationwide system with thousands of high-power base stations. Pagers were developed in the 1950s and 1960s, and became widely used by the 1980s. In the 21st century, the widespread availability of cellphones and smartphones has greatly diminished the pager industry. Nevertheless, pagers continue to be used by some emergency services and public safety personne ...

Loitering
Loitering is the act of remaining in a particular public place for a prolonged amount of time without any apparent purpose. While the laws regarding loitering have been challenged and changed over time, loitering is still illegal in various jurisdictions and specific circumstances. Prohibition and history Loitering has historically been treated as an inherent preceding offense to other forms of public crime and disorder, such as prostitution, begging, public drunkenness, dealing in stolen goods, drug dealing, scams, organized crime, robbery, harassment/mobbing, etc. Loitering provides a lesser offence that can be used by police to confront and deter suspect individuals from lingering in a high-crime area, especially when criminal intent is suspected but not observed. Local areas vary on the degree to which police are empowered to arrest or disperse loiterers; limitations on their power are sometimes made over concerns regarding racial profiling and unnecessary use of pol ...

Pay Phone
A payphone (alternative spelling: pay phone) is typically a coin-operated public telephone, often located in a telephone booth or in high-traffic outdoor areas, with prepayment by inserting money (usually coins) or by billing a credit or debit card, or a telephone card. Prepaid calling cards also facilitate establishing a call by first calling the provided toll-free telephone number, entering the card account number and PIN, then the desired telephone number. An equipment usage fee may be charged as additional units, minutes or tariff fee to the collect/third-party, debit, credit, telephone or prepaid calling card when used at payphones. By agreement with the landlord, either the phone company pays rent for the location and keeps the revenue, or the landlord pays rent for the phone and shares the revenue. Before the ubiquity of mobile phones, payphones were often found in public places to contribute to the notion of universal access to basic communication services. In the late ...
