What is ACCOLC?
'''ACCOLC''' ('''Access Overload Control''') was a process in the [[United Kingdom]] for limiting [[mobile telephone]] use in times of emergencies. It is like the GTPS ([[Government Telephone Preference Scheme]]) for [[landline]]s. This process allowed the telephone networks to limit access in a specific area to registered numbers only and is normally started by the Police Incident Commander (although it can be invoked by the [[Cabinet Office]]). The [[emergency service]]s are responsible for registering their key numbers in advance. ACCOLC was replaced by [[MTPAS]] (Mobile Telecommunication Privileged Access Scheme) in 2009.<ref>{{cite web|url=https://www.gov.uk/guidance/resilient-communications|title=Resilient communications - GOV.UK|publisher=gov.uk|date=20 February 2013|access-date=17 June 2021}}</ref> == Use == ACCOLC was deployed at the [[Hillsborough disaster]].<ref>{{cite web|title=Printed incident logs of all calls received to the South Yorkshire Police control room on Special Incident 2 15 – 26 April 1989|url=http://hillsborough.independent.gov.uk/repository/docs/SYP000110600001.pdf|publisher=Crown|accessdate=1 October 2012|archive-url=https://web.archive.org/web/20160303223353/http://hillsborough.independent.gov.uk/repository/docs/SYP000110600001.pdf|archive-date=3 March 2016|url-status=dead}}</ref> == References == {{reflist}} == Other websites == * [https://web.archive.org/web/20120107004751/http://legacy.london.gov.uk/assembly/reports/7july/follow-up-report.pdf London Assembly 7 July Review Committee Volume 4 Follow up report] Including report on ACCOLC being invoked around [[7 July 2005 London bombings|Aldgate]] on 7 July by the [[City of London Police]] without reference to [[Gold Silver Bronze command structure|GOLD]] control. * [http://www.cabinetoffice.gov.uk/sites/default/files/resources/resilient_comms_guidance.pdf Introduction to Resilient Communications (Cabinet Office).] [[Category:Government of the United Kingdom]] [[Category:Telecommunications]]
