Firmware is chip-dependent and cannot be changed or altered on site. As a
general rule, all firmware is on ROM microchips. Firmware is built into the
M2317 telephone and into the Meridian 1 system.
The following functions are performed by firmware in the M2317 digital
telephone:
• Predial
• Last Number Redial
• Saved Number
• Redial Saved Number
• Timer
• Time and Date
• Call Processing
The M2317 Telephone is available on X11 release 9 and later software.
All information related to the programmable keys must be downloaded into
the M2317 RAM memory through the DLC or ISDLC. Downloading to the
telephone is performed when the system is loaded or when a telephone is
enabled.
Softkeys are automatically defined for the telephone based on Class of
Service (CLS), database, or package restrictions. Softkeys work only in
conjunction with the LCD display screen.
