Figure 5-2. Example Directory Number assignments for Extension 200
When a caller originates a call, the call appears on the first available PDN key. If all PDNs are 
unavailable, the call will select the EXT LED.
When calls come in to a DN, the call appears on the first available DN key. If the call is to your PDN 
and no PDN key is available, the caller hears a busy tone.
Directory numbers may be assigned to FF keys 25-32. These are non-appearing keys.
Intercom voice calls only go to the PDN extension but light the corresponding NPDN keys red. A tone 
call follows the appropriate ring status (immediate ring, delayed ring, etc.) for any extension.

status of different features and callback messages from other extensions.
Caller ID Display Information
Prior to Version 3.0, the telephone would not display Caller ID information for an extension that was 
in use when a call was received. In Version 3.0 or higher, Caller ID information is displayed on the 
second line of an LCD display when an incoming call is received during conversation. If a second 
incoming call is from another extension, the LCD displays the extension name or
 number. If the 
second incoming call is from a CO, the LCD displays the CID information transmitted from the caller. 
Caller ID displays the second incoming call as follows:

DSS/72 Console
Description
The DSS/72 console is a 72-key console that can be attached to a key telephone. The 72 keys on the 
DSS/72 can be programmed as Direct Station Select (DSS) keys for internal lines.
In addition to providing direct station selection, the DSS keys also provide Busy Lamp Fields (BLFs) 
that allow you to monitor the status of other extensions. The LED lights red when the assigned 
extension is busy, and lights green when Call Forwarding or Do-Not-Disturb (DND) are activated.
For additional information, see “Flexible Function Keys” on page 5-46.
Hardware Requirements
• VB-44320

• FF4: FF Key Assignment
Considerations
• Pressing a DSS key while connected to an outside line places the line on hold.
• A maximum of 12 DSS/72 consoles can be connected to a 96-port system.
EM/24 Console
Description
The EM/24 is a 24-key console that can be attached to a key telephone. The 24 keys on the EM/24 can 
be programmed as Direct Station Select (DSS) keys for internal lines.
In addition to providing direct station selection, the DSS keys also provide Busy Lamp Fields (BLFs) 
that allow you to monitor the status of other extensions. The LED lights red when the assigned 
extension is busy and lights green when Call Forwarding or Do-Not-Disturb (DND) are activated.

Flash
Description
You can send a flash signal on your telephone to release an outside line and then either automatically 
reseize the same outside line or switch to extension dial tone status by pressing the FLASH or PROG 
key.
Trunk programming determines whether your phone reseizes the outside line or switches to extension 
dial tone status.
Note: The following is available for future use only: Alternatively, a extension setting determines 
if pressing a CO key will place the call on exclusive hold or send a flash to the trunk.

Considerations
• You can send a longer or shorter flash signal, depending on whether you use the FLASH or 
PROG key (flash tone lengths are set for the FLASH and PROG
 keys through system 
programming).
Flexible Function Keys
Description
You can assign frequently used functions to programmable keys on key phones, DSS/72 consoles, 
and EM/24 consoles. All keys not already assigned as line or speed dialing keys are available for 
programming.
You can store either Fixed Feature codes or Flexible Feature codes in an FF key. (The LED of the 
Flexible Function [FF] key will not light when digits are stored in the key.) Fixed Feature codes are 
hard-coded and cannot be changed. Most features; however, can also be assigned flexible codes 
according to the System Dial Plan. This allows the flexible codes to be changed in the dial plan 
without having to re-program extensions.
When a flexible code is programmed into an FF key or soft key, the System translates the flexible 
code into the fixed code. You can use either the Fixed Feature code or your System’s Flexible Feature 
code when programming FF keys. Table 5 on page 5-49 reflects both Fixed Feature codes and the 
System defaults for Flexible Feature codes.
