Backup and restore procedures
ITG card
Data configured on the MAT PC (for example, address translation tables and
DSP configuration) are locally saved on the MAT PC and also downloaded
to the ITG cards. The ITG card stores this data in its internal Flash File
volume (Flash EPROM which acts as a disk drive). The MAT PC can query
the card and retrieve data from it. If the ITG card is replaced, you can use the
version of data stored on the MAT PC to configure the new card with the
same data as the replaced card.
