Installation Data Handling
25 Installation Data Handling
The RBS contains a database which stores information relating to the
RBS as a whole, and to each RU within the RBS.
The most important purpose of the database is to provide effective aid
for:
• General operation and maintenance
• Fault diagnosis
• Fault localisation
• Traceability
The information stored in the database falls into one of two categories:
configuration information or history information.
The database is at least partly accessible to each of the following:
• Other functions within the RBS
• The operator via the OMT
• The BSC via the A-bis interface
