11 Transmission
This chapter describes the transmission standards supported by the RBS 2111
Second Generation.
The RBS can act as an end node of a Transport Network (TN).
For more information about the transmission interface, see Section 8.3 on
page 30.
12 External Alarms
This chapter describes the external alarms that are available for the RBS.
Customer-Specific External Alarm
The RBS connected to an OVP provides four external alarm input ports to be
used for customer-specific purposes.
It is possible to configure an alarm generated by a closed or open loop
condition. A closed loop condition means that an alarm is triggered when an
open switch is closed. An open loop condition means that an alarm is triggered
when a closed switch is opened. The open loop condition is the default.
The external alarms are defined at the installation. They are defined by using
the OMT or from the BSC using the remote OMT.
For more detailed information on the use of the OMT, see OMT User’s Manual,
EN/LZN 720 0001
Note: For OMT Version R31 and later, the OMT parameters are also included
as on-line help.
