(Direct-Inward-Dial): A special telephone service in which there is no direct relationship between one line and a specific telephone number, but where many different numbers can be served by the same trunk or group of trunks. To specify which number was called, identifying digits are dialed on the trunk and decoded by the equipment. By definition, calls can only be received with this type of service, however, many phone companies have enhanced DID service so that calls can be made on DID trunks as well. This allows for greater efficiency (since they can be used for two purposes) and also a higher quality patch (since it is switched and handled by the phone company's central office). This is called two-way DID, but it is not available from all phone companies or from all central offices.

A service offered by telephone companies which allows the last 3 or 4 digits of a phone number to be transmitted to the destination exchange. For example, a company could have 10 incoming lines, all with the number 234 000. If a caller dials 234 697, the call is sent to 234 000 (the company's exchange), and the digits 697 are transmitted. The company's exchange then routes the call to extension 697. This gives the impression of 1000 direct dial lines, whereas in fact there are only 10. Obviously, only 10 at a time can be used.
