Alter directory number series for abbreviated numbers

ASB 150 features a service called 'common abbreviated numbers'. On a call to a common abbreviated number, the abbreviated number is translated into a new number containing up to 17 digits. This command is used to change the directory number series for abbreviated numbers.

The “-” character is used as “wild card” when defining a directory number series for abbreviated numbers.

Example:

Directory number series | Defined abbreviated numbers
602 | 602
61- | 610-619
62-- | 6200-6299
5--- | 5000-5999

There is no direct procedure for changing an existing number series to a new series being in conflict with the existing one. In such cases you have to start with changing to an arbitrary, vacant number series, and then you may change this series to the desired one.

What happens to existing directory numbers?

Directory number series | Created abbreviated numbers
6-- is changed to 8-- | 600-699 is changed to 800-899
6-- is changed to 8--- | 600-699 is changed to 8000-8099 (8100-8999) is not programmed
6-- is changed to 8- | 600-699 is changed to 80-89

Example:

#### WARNING! 610-699 remain in the E2 memory but are inaccessible

Note that the references to the previous numbers will remain. These references should either be erased or replaced by the new number. See description of command group 56 listing commands referring to directory numbers.

If no number is entered, an error message will be displayed because the directory number is the only identity of the abbreviated number; in other words, there must be one directory number for each abbreviated number.

To delete a directory number series for common abbreviated numbers from the system, see command 5513 Delete common abbreviated number series.
