DATA SAVING
OUTLINE
Configuration backup
The backup operation concerns all the parameters not reinitialized during a warm reset:
- global data (software version, backup time and date, etc)
- configuration data (types of boards and terminals, characteristics of terminals and groups, keys
and repertory settings, numbering plans, directory, barring tables)
- data recorded by users (mail, appointment reminders, forwarding)
- metering counters
The configuration data backup can be activated in either of 2 ways:
- manually by the installer (MMC-PC or Station backup command)
- automatically and periodically, at a time programmed by the installer, using MMC-PC or Station
The backup session is exclusive of any MMC-PC or MMC-Station operation or customization session;
any modification is ignored during backup. During the backup, avoid any activation or inhibition of
services (appointment reminders are not protected, diversions and filtering are refused) which would
modify the settings.
Any system data modification and any hardware modification by MMC PM5 or Station must be fol-
lowed by a backup.
Duration of a backup session: about 20 seconds per module; more than a minute for a multi-module
installation.
At the end of the session, a message appears in the hardware message table (to signal failure) or in
the system history table (to signal success).
Configuration restore
The restore session is activated manually by the installer (MMC-PC or Station restore command). All
the saved data are restored.
Duration of a restore session: 1 to 7 minutes.
At the end of the session, a message appears in the hardware message table (failure indication) or in
the system history table (success indication).
