8 Transmission
The RBS 2106 supports two transmission standards:
• T1 1.5 Mbit/s, 100 Ω, with internal synchronisation
• E1 2 Mbit/s, 75 Ω, with PCM synchronisation
• E1 2 Mbit/s, 120 Ω, with PCM synchronisation
9 External Alarms
The RBS 2106 supports a maximum of 16 external alarms. The external alarm
device can set the alarm by either an open or a closed condition.
The alarm device connected to the screw terminals should be isolated relay
contacts. A closed contact (logic zero) is required to be below 2 kΩ, and an
open contact (logic one) above 100 kΩ. The current through a closed 0 Ω
contact is 1.2 mA. The voltage between terminals with an open contact is 24 V
DC.
The external alarms are defined at the installation. They are defined by using
the Operation and Maintenance Terminal (OMT) or from the BSC using the
remote OMT.
