Key Telephone Features Section 700 - OperationFlashDescriptionYou can send a flash signal on your telephone to release an outside line and then either automaticallyreseize the same outside line or switch to extension dial tone status by pressing the FLASH or PROGkey.Trunk programming determines whether your phone reseizes the outside line or switches to extensiondial tone status.Note: The following is available for future use only: Alternatively, a extension setting determinesif pressing a CO key will place the call on exclusive hold or send a flash to the trunk.Hardware Requirements• N/ARelated Programming• FF1-1: Flash Timer• FF2: Flash Pattern• FF2: Flash Key Operation• FF3: Flash on PROG (Recall)• FF3: Flash on CO key (For Future Use)Considerations• You can send a longer or shorter flash signal, depending on whether you use the FLASH orPROG key (flash tone lengths are set for the FLASH and PROG keys through systemprogramming).Flexible 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 on page 5-49 reflects both Fixed Feature codes and theSystem defaults for Flexible Feature codes.
