7.3 Data Operation

After the data operation on a workstation, the MML service in the BAM analyzes the
commands and the configuration management service is responsible for saving the
modified data into the BAM database and converting data format. Later, the
Exchange service program of the BAM sends the converted data to the data
management system of the FAM, which implements data updating in all service
modules to ensure data security. The data files sent to the FAM include DB_?.DAT,
where ? indicates the module number (2–252), and different service processing
modules are loaded with different data files. Functions about data operation
management include data format conversion, data setting, CRC, data backup, and
automatic format setting.
I. Data format conversion
Data format conversion means that the BAM converts the format of operation and
maintenance-oriented data received from workstation to the data format that can be
processed by the Service Processing Module. An operator can convert some or all
modified data as required. After conversion, the data can be loaded to the Service
Processing Module. This operation is needed in the following three cases:
The operator forces to regenerate data files.
When the operator performs the operations of adding, deleting and modifying
data with the MML, the data management console automatically starts the
format conversion command to update data files.
After receiving the format conversion command from the traffic measurement
console, the BAM performs format conversion and writes the converted data to
the data file of the corresponding module.
II. Data setting
Data setting sends the data with the converted format in the BAM to the
corresponding modules of the FAM.
After the data in the BAM are modified, data setting must be performed. The time of
data setting is related to the connection status between the BAM and FAM, and the
formatting switch. When the BAM is connected with the FAM, data setting is
automatically conducted once the data in the BAM are modified. Otherwise, data
setting is not automatically conducted until they are connected. Data setting
operation will be conducted in two cases:
1) After the operations of adding, deleting or modifying data are carried out, the
BAM will automatically perform the data sending operation
2) The operator can carry out the data setting command to forcibly perform the
operation.
