You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.236.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 06:21, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Speed dial''' is a function available on many [[telephone]] systems allowing the user to place a call by pressing a reduced number of keys.  This function is particularly useful for phone users who dial certain numbers on a regular basis.

In most cases, the user stores these numbers in the phone's memory for future use.  The speed dial numbers are usually accessed by pressing a pre-determined key or keys on the phone, followed by a one or two-digit code which the user assigns to each number; however for ease of use, on many systems a call may be placed by pressing and holding one key on the numeric keypad.

Speed dialing is also available via Custom Calling features from the Telephone Company's Central Office. The numbers are programmed by the subscriber through the standard telephone dial, and speed dial calls are placed by dialing simply the digit and waiting a few seconds on a standard rotary dial phone and an older 10 key Touch Tone phone, or by dialing the number and the # key to instantly connect the call on a modern 12 key Touch Tone phone.

Most [[mobile phone]]s have a [[contact list]] feature which provides similar abilities although most have an instant call button which only requires one click.

==History==
The capability for speed dial historically dates at least as far back as the [[Number One Electronic Switching System]] (1ESS) in 1965.<ref>[https://www.youtube.com/watch?v=28V4QPNCaXc Electronic Central Office Debut, Succasunna, NJ (video)]<!-- former url: http://techchannel.att.com/play-video.cfm/2015/1/28/AT&T-Archives-Electronic-Central-Office-Debut-Succasunna-NJ-1965 --></ref><ref>((cite web | url=http://www.greatachievements.org/?id=3625 | title=Telephone Timeline - Greatest Engineering Achievements of the Twentieth Century ))</ref> Other early "instant dialers" dating back to 1972 also included punched card machines<ref>((Cite journal | url=https://ieeexplore.ieee.org/document/5180739 |doi = 10.1049/ep.1973.0072|title = Fluorides store more energy|journal = Electronics and Power|volume = 19|issue = 3|pages = 51|year = 1973))</ref> and magnetic tape machines.<ref>((cite web | url=http://www.britishtelephones.com/auto201.htm | title=AUTODIAL No. 201 ))</ref>

[[Metal–oxide–semiconductor]] (MOS) [[integrated circuit]] (IC) telephone technology enabled speed dialing on [[push-button telephone]]s in the early 1970s. [[MOS memory]] chips were used to store [[phone numbers]], which could then be used for speed dialing at the push of a button.<ref name="Wireless-World"/><ref name="Valery1974"/><ref name="US23">((cite book |title=Electronic Components |date=1974 |publisher=[[U.S. Government Printing Office]] |page=23 |url=https://books.google.com/books?id=HikuAAAAMAAJ&pg=PA23))</ref> This was demonstrated by the British companies [[Pye Ltd.|Pye TMC]], [[Elliott Brothers (computer company)|Marconi-Elliott]] and [[General Electric Company|GEC]] in 1970.<ref name="Wireless-World">((cite journal |title=Push-button telephone chips |journal=[[Wireless World]] |date=August 1970 |page=383 |url=https://www.americanradiohistory.com/hd2/IDX-Site-Early-Radio/Archive-Wireless-World-IDX/70s/Wireless-World-1970-08-OCR-Page-0023.pdf))</ref><ref name="Valery1974">((cite journal |last1=Valéry |first1=Nicholas |title=Debut for the telephone on a chip |journal=[[New Scientist]] |date=11 April 1974 |volume=62 |issue=893 |pages=65–7 |url=https://books.google.com/books?id=u0O-g0_fbrIC&pg=PA65 |publisher=[[Reed Business Information]] |issn=0262-4079))</ref> Between 1971 and 1973, the American company [[Bell Laboratories]] develop a push-button MOS telephone called the "Touch-O-Matic" phone, which could store up to 32 phone numbers. This was made possible by the low cost, low power requirements, small size and high reliability of [[MOS transistor]]s, over 15,000 of which were contained on ten IC chips, including one chip for logic, one for the dial interface, and eight for memory.<ref>((cite journal |last1=Gust |first1=Victor |last2=Huizinga |first2=Donald |last3=Paas |first3=Terrance |title=Call anywhere at the touch of a button |journal=[[Bell Laboratories Record]] |date=January 1976 |volume=54 |pages=3–8 |url=http://doc.telephonecollectors.info/dm/76Jan_BLR_P3_Touch_A_Matic.pdf#page=2))</ref>
