17-56 Dialing translations
Local dialing to a different area/city code (no area/city code required)
Standard 1.0 System Administration Guide January 1998
Local dialing to a different area/city code (no area/city code
required)
Introduction
This scenario is almost identical to the first scenario because
there is local dialing from one area/city code to a different area/
city code. However, the difference is that no area/city code is
required in the dialable DN. Using the example from
page 17-52, the dialable DN would be 9-555-2121 instead of
9-905-555-2121.
Scenario
This situation may occur if, for example, a metropolitan area is
in the process of adopting a new area code in which certain
exchanges will be considered local (as described in the previous
example).
Therefore, in the exchange code diagram that follows, the first
column of exchange codes in the 905 area code are local if
dialed from the 416 area code. In order to make the transition
easier for people in the area, the service provider will allow
calls to the local exchanges in the 905 area code to be placed
without the area/city code since this is what people are
accustomed to dialing. However, after a certain specified date
(when the phone company ends the transition period), the new
area code will have to be entered and the translation table
prefixes updated (to those in the previous example).
