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 dialling 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 18 on page 165 reflects both Fixed Feature codes and the
System defaults for Flexible Feature codes.
