Renumbering Extensions and Lines/Trunks

The table below gives a brief overview of the extensions and lines/trunks that can or cannot be renumbered and lists their factory settings.

Single Renumbering

Single Renumbering should be used whenever the extension numbers you are changing to or from are not sequential.

Single Renumbering can be used to assign a specified extension number to the following: extensions, adjuncts, lines/trunks, telephones, ARS access code, Calling Groups, Idle Line access code, LDN, Paging Groups, Park Zones, pools, and Remote Access code.

The system is not forced idle when renumbering extensions, ARS access code, Calling Groups, Idle Line access code, LDN, Paging Groups, Park Zones, pools, and Remote Access code. However, when you are renumbering a line/trunk, the line is forced idle during the renumbering process.

Block Renumbering

Block renumbering can be used only when the extension numbers you are changing from are sequential and the extension numbers you are changing to are sequential. Block renumbering can be used to assign extension numbers to a group of extensions, adjuncts, or lines.

When you are renumbering extensions using block renumbering, the system is forced idle during the process.

DSS Renumbering

System renumbering is used to assign the beginning extension number in a page. A page is the range of extension numbers that is assigned to a DSS. A single DSS can have three pages of extension numbers, with 50 extension numbers for each page, for a total of 150 extension numbers. When two DSSs are connected, each page's capacity is increased to 100 extension numbers. The two connected DSSs can have three pages of extension numbers, for a total of 300 extension numbers.

Page buttons work as Shift keys on a keyboard. When an operator presses a Page button, he or she selects a page of the DSS, which corresponds to a range of 50 (for a single DSS) or 100 (for two connected DSSs) extension numbers. The factory settings for Page buttons are: the Page 1 button begins with Extension 0, the Page 2 button begins with 50, and the Page 3 button begins with 100.

If two DSSs are attached, the factory setting must be changed so that the difference between extensions assigned to the range is at least 100. For example, assign the Page 1 button to begin with Extension 100, the Page 2 button to begin with Extension 200, and the Page 3 button to begin with Extension 300. Page button assignments should be sequential.

The beginning extension number associated with each Page button is the same for all DSSs and cannot be programmed differently for individual operator positions.

Each Page button can be programmed to begin with any extension number in the range of 0 through 9950 that is a multiple of 50. However, to expedite call handling, the assignments should be sequential. The range starting with the lowest extension number should be assigned to Page 1, the range starting with the next higher extension number should be assigned to Page 2, and the range starting with the highest extension number should be assigned to Page 3. You cannot program individual buttons on a DSS.

Operator Park Zones must be included in the extension number range specified for one of the Page buttons.

Each of the 50 DSS buttons corresponds to one of three extension numbers. The specific extension number is determined by the Page button that the system operator presses. For example, if the first extension number for the Page 1 button is programmed to be Extension 100, the DSS buttons and associated LEDs on a single DSS correspond to Extensions 100 to 149.

Remote Access Renumbering

The number assigned to a line/trunk can be reprogrammed and used (after appropriate digit deletion and addition) as a Remote Access code. Users can call in on a line/trunk that has been programmed to supply the Remote Access code, and reach a system dial tone (barrier code entry should be programmed). From the system dial tone, users can call extensions or Calling Groups or access a line/trunk to make an outside call (if permitted). See Remote Access for more information.
