Plugging in the telephone
After plugging in the telephone or at each reset, the bootstrap compares the check sum of the
software to the default value. It ensures, that software can be loaded, only if it compatible with
the terminal.
The phone also ensures that initial factory data was written during the factory procedures. If
the phone has no factory data (or it is damaged) and no factory SW can be started all available
LEDs will be activated to indicate the error. If the phone has no factory data (or it is damaged)
and factory SW starts automatically – The screen stays blank to indicate the error.
Plug in the telephone.
The bootstrap performs a check sum test.
• If successful, the software version is indicated in the display, e.g.
T015_ODE.xx1.
• otherwise, the bootstrap returns the message NO SOFTWARE LOADED
Note:
In this case, the software can be downloaded from the telephone system or
via the TCM tool.

erroneously with the CM application SW depending if the phone was plugged to a CM before.

menu button and the Drop button pressed simultaneously. To switch manually to CM
