Unreferenced date December 2009 Abbreviated dialing is the use of a very short telephone number to reach public services . Typically these are two or three digits, and are most commonly known as being emergency telephone number s like 9 9 9 , 1 1 2 and 9 1 1 . Other services may also be available this way, such as the N11 code s in the NANP . Their purpose is to be universal, short, and easy to remember. For text messaging , the technical equivalent is a short code , however these are rented by their private users rather than being universal and for public services.

In North America , permissive dialing is the ability to make phone calls in an area subject to a newly introduced area code using both the new and preexisting dialing methods. When an area is given a new area code under a split plan , the area s previous area code would no longer be valid for calls in the area, so calls to numbers using the old area code will not work. To alleviate misdialing frustration, the local routing can be set up such that both the old and new area codes will work for the same telephone station . During this period, the local numbering authority must not reassign the area s existing telephone exchange exchanges to the remaining area of the old area code, nor vice versa. At the end of the permissive dialing period, the old area code is no longer valid for numbers in the affected area. Under an overlay plan , permissive dialing refers to the ability to continue to connect calls via 7 digit dialing while also making 10 digit dialing valid. Again, the affected area must not introduce any new ambiguous telephone exchanges. At the end of the period, 10 digit dialing becomes mandatory.

In the Hacker computer security computer hacking scene of the 1980s, demon dialing was a technique by which a computer is used to repeatedly dial a number usually to a crowded modem pool in an attempt to gain access immediately after another user had hung up.

A similar technique was sometimes used to get the first call for prizes in radio call in shows, thus leading to the adoption of random fifth caller, seventeenth caller etc. by radio stations to circumvent this practice.

More recently, with the increasing number and decreasing geographic size of area codes, it is possible to call a number in another area code that is not long distance, and such a call does require the area code, but not the trunk digit initial 1 . Traditionally to avoid number confusion, identical exchange numbers in different area codes would be assigned as far apart from each other as possible, so that callers living near a state or NPA boundary would not get two areas in different NPAs confused.

In DID service the telephone company provides one or more Trunking Telecommunications trunk lines to the customer for connection to the customer s PBX and allocates a range of telephone number s to this line or group of lines and forwards all calls to such numbers via the trunk. As calls are presented to the PBX, the dialed destination number Dialed Number Identification Service DNIS is transmitted, usually partially e.g., last four digits , so that the PBX can route the call directly to the desired Extension telephone telephone extension within the organization without the need for an operator or attendant. The service allows direct inward call routing to each extension while maintaining only a limited number of Trunk telecommunications subscriber lines to satisfy the average concurrent usage of the customer. Traditionally, DID circuits were analog. These types of DID trunks had to be powered by the customer premises equipment. The central office equipment detects the power state of the line and disables service if the circuit is not powered up.

Fixed Dialing Number FDN is a service mode of a GSM phone s Subscriber Identity Module SIM card. Numbers are added to the FDN list, and when activated, FDN restricts outgoing calls to only those numbers listed, or to numbers with certain prefixes. A notable exception is that emergency calls to emergency telephone number 112, 9 1 1, 999 and the like are exempt and typically require no SIM or even an active service contract . Incoming calls are not affected. Not all SIM cards support this feature. PIN2 must be entered beforehand, which is unique to each SIM card and initially provided by the network operator. Doing so prevents unauthorized users from changing or disabling the FDN list. This code is separate from the main PIN1 number which, when set, can lock and unlock the SIM card for both inbound and outbound calling. One practical application of FDN is for parent s to restrict the phone numbers to which their children can dial. For example, the list may give the child permission to call only their mother and father, a relative, or a family friend.

Direct Distance Dialing DDD or direct dial is a telecommunications term for a telecommunications network network provided service feature in which a call originator may, without telephone operator operator assistance, call any other User telecommunications user outside the local calling area. DDD requires more digits in the telephone number number dialed than are required for calling within the local area or area code . DDD also extends beyond the boundaries of national public telephone network, in which case it is called International Direct Dialling or International Direct Distance Dialing IDDD . DDD is a North American Numbering Plan term considered obsolete since completing a call in any manner other than direct dialing became rare. In the United Kingdom and other parts of the Commonwealth of Nations , the equivalent terms are or were STD , for subscriber trunk dialling , and ISD for international subscriber trunk dialling. History The telephone industry made a United States first in the New Jersey communities of Englewood, New Jersey Englewood and Teaneck, New Jersey Teaneck with the introduction of what is known now as Direct Distance Dialing. Starting on November 10, 1951, customers of the ENglewood 3, ENglewood 4 and TEaneck 7 exchanges who could already dial New York City and area were able to dial 11 cities across the United States, simply by dialing the three digit area code and the seven digit number which at the time consisted of the first two letters of the Telephone exchange names Exchange Name and five digits . The 11 cities and their area codes at that time ... dialing, TSPS provided the extra computer power. The reach of DDD was limited due to the inefficiency ... to extend Direct Dialing beyond North America and its nearby islands.

It is a term common to Analog synthesizer synthesizer programming, and is a typical waveform available on many synths. The exact shape of the wave is determined by the duty cycle of the oscillator . In many synthesizers, the duty cycle can be modulated sometimes called pulse width modulation for a more dynamic timbre. The pulse wave is also known as the rectangular wave , the Periodic function periodic version of the rectangular function .
