Section 700 - Operation Chapter 5. Key Telephone FeaturesICX-40-700 ICX (International) issued December 1999 5-45Flexible Function KeysDescriptionYou 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 forprogramming.You can store either Fixed Feature codes or Flexible Feature codes in an FF key. (The LED of theFlexible Function (FF) key will not light when digits are stored in the key.) Fixed Feature codes arehard-coded and cannot be changed. Most features; however, can also be assigned flexible codesaccording to the System Dial Plan. This allows the flexible codes to be changed in the dial planwithout having to re-program extensions.When a flexible code is programmed into an FF key or soft key, the System translates the flexiblecode into the fixed code. You can use either the Fixed Feature code or your System’s Flexible Featurecode when programming FF keys. Table 5-5 on page 5-47 reflects both Fixed Feature codes and theSystem defaults for Flexible Feature codes.OperationTo assign Fixed Feature codes to an FF key:To assign Flexible Feature Codes to an FF key:Action Result1.
