Direct Dialling In. Normally available on ISDN lines. A company may have 10 lines and 100 telephone numbers. When any of the telephone numbers are dialled by an incoming caller the call is put on to any line that is free. At the same time the dialled number is passed to the telephone system. The phone system uses this to route the call to the intended recipient. Typically used to provide direct dial numbers for extension users, fax machines, departments or groups of extensions. This is much more efficient than the older method of using different sets of lines for different numbers because all lines can be used for all numbers and so less lines need to be rented overall to provide the same level of service.
