All RBS 2206 models fulfils the Electromagnetic Compatibility (EMC) requirements
according to:
ETS 300 342-2, the BTS product standard, in line with the European EMC Directive
89/336/EEC.

The RBS 2206 is CE marked in order to show this compliance.
3.7 External Alarms
RBS 2206 provides connections for external alarms. The external alarms are defined by the
customer and are reported to the BSC via LAPD signalling on the A-bis O&M interface.
There are 16 external alarms available (unoccupied). The external alarms are defined by
using the Operation and Maintenance Terminal (OMT) or the Remote OMT. The external
device sets the alarm by either an open or closed condition.
3.8 Battery Backup
Battery backup is available in an external cabinet, BBS 2000, with the same size as the
RBS 2206 cabinet, providing up to 8 hours of backup.
In the external battery cabinet a Battery Fuse Unit, BFU, is installed. The BFU supervises
and connects/disconnects the batteries at low voltage. It is possible to supply external
transmission equipment outside the RBS 2206 with power from the system voltage (+24
VDC). This can be provided either from the cabinet or prioritised from the battery backup.
It is possible to share battery backup between RBS 2206 and RBS 2202/200.
