RBS Product Description
8.2 Battery Backup
Battery backup is used to power the site during mains failure and also to protect
the site from short-term interruptions in the mains supply. The backup time is
dependent on for example RBS configuration, traffic load and temperature.
Internal Battery Backup
The following battery backup levels can be achieved in the cabinet:
• Full: one hour backup time
• Half: half an hour backup time
If no TM equipment is used, additional batteries can be installed in the TM
compartment. The backup time will then be enhanced by 100%.
External Battery Backup
Ericsson supplies two external battery backup alternatives: the BBS or the
BBU 9500. Both are connected through the DC filter.
Note: The maximum distance between the RBS and BBS must not exceed 10
meters to prevent damage from, for example, lightning.
8.3 Output Power to TM
The RBS can supply the TM with power according to the table below.
