Selector Console Area

The selector console consists of:

•Hundreds Group Select (HGS) Buttons and Associated Lamps

The HGS buttons (8 buttons on the Basic model [Figure 2-13]and 20 buttons on the Enhanced model [Figure 2-14])are labeled with different hundreds group numbers used for the system. For example, for a 4-digit extension number system, these buttons can be labeled 21, 22, 34, and so on. On the other hand, these buttons can be labeled 1, 2, 3, and so on for a 3-digit system. The lamp associated with the HGS button lights when the button is pressed and remains lighted until a different HGS button is pressed.

Additional group select buttons may be assigned to feature buttons. This allows a console with a Basic Selector Console to access 20 hundreds groups.

•Direct Extension Selection (DXS) With Busy Lamp Field (BLF)

The 100 DXS buttons are labeled 00 through 99. Each DXS button, when combined with one of the eight HGS buttons on the Basic Selector Console or 12 HGS buttons on the Basic Attendant Console, represents a particular extension number. This extension number may be assigned to a voice terminal, data module, paging zone, Terminating Extension Group (TEG), Uniform Call Distribution (UCD) group, or Direct Department Calling (DDC) group. In addition, a DXS button can represent a particular trunk group. The lamp associated with each DXS button is used to determine the status of the facility associated with the button.
