public telecommunications operator

public telecommunications operator (PTO) A UK agency licensed to provide data transmission services to organizations or private individuals, where the services cross public rights of way. Within the UK, until the mid-1980s, the only organization able to offer such services was British Telecom (previously the GPO) and, for purely historical reasons, the civic authorities in the city of Hull. At the time of the BT privatization, legislation was enacted that allowed the creation of further PTOs, although for a long time only Mercury took advantage of this. There are now a large number of organizations taking out licenses to act as PTOs, driven in part by the installation of optical fiber networks in metropolitan areas. See also public network operator.

Citation styles

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
