• Blank lines are ignored.
• When an identifier is not recognized or is invalid, the entire line is ignored. Similarly, if an
identifier is valid but the data itself is invalid or incomplete, the line is ignored.
• When an identifier is valid with valid and complete data, but the data is not applicable to the
current state of the phone, the data is retained for possible use later, and is treated as data to
be backed up at the appropriate time.
For example, if button labels for an SBM24 button module unit are present, but no such
module is attached to the deskphone, the button labels are retained.
• When more than one line contains a value for an option, parameter, or Contacts entry, the
last value read is retrieved, to allow new values to overwrite previous values as lines are read
from the backup file. In all other cases, the line order in the backup file has no bearing on
retrieval.
• The existence of invalid data does not constitute a failed retrieval. The success of the
retrieval process requires the phone to get the backup file and successfully restore valid data.
