How to define built-in ports for external alarm with 2 DUL boards in RBS6601 1. Hardware connection and alarm design 1.1 HW connection
There are 2 DUL boards are put into the RBS6601.One is master to control support system,the other is slave,not control support system. For master DUL board,the ecport is connected to SUP’s EC A port,and for slave DUL board,ecport is connected to EC B port.

2. The meaning of attributes used in MO AlarmPort
activeExternalAlarm : There are 2 kind states. True or False. When there is an external alarm,the value is True,otherwise,false.
administrativeState : There are 2 kind states. Unlock(1) or Lock(0).When this alarm port is used,its state is Unlock,otherwise,Lock.
availabilityStatus & operationalState : There are 11 availability statuses,and with different value for each status. operationalState with 2 states,ENABLE(1) & DISABLE(0).Only when the external alarm is in normal state,the attribute availabilityStatus=0(NO_STATUS),and then operationalState=1.For availabilityStatus’s other statuses,it means the external alarm has some problem, and then operationalState=0.
normallyOpen : 2 states,True & False.When opening the circuit triggers the alarm,the value is False,and it is True,when choose closing the circuit triggering the alarm.
probableCause : For different cause,it has different corresponding level code according to 3GPP TS 32.111-3.
perceivedSeverity : For different alarm,it has different corresponding level code according to 3GPP TS 32.111-2.
3. Configuration
3.1 On master DUL board
//Create SUP MO cr Equipment=1,HwUnit=SUP-1 cr Equipment=1,HwUnit=SUP-1,EcPort=1 //This MO indates the ecport on master DUL board is connected to EC A port. cr Subrack=1,Slot=1,PlugInUnit=1,EcPort=1 set Subrack=1,Slot=1,PlugInUnit=1,EcPort=1 hubPosition A // This MO indates the ecport on slave DUL board is connected to EC B port. cr Equipment=1,ExternalNode=1 cr Equipment=1,ExternalNode=1,EcPort=1 set Equipment=1,ExternalNode=1,EcPort=1,hubPosition B //Set the master DUL control the support system. set Equipment=1,HwUnit=SUP-1 supportSystemControl true //Create the alarm port MO.And then can set these attribute,for example,userLabel/alarmsLogan, according to the external alarm plan. cr HwUnit=SUP-1,AlarmPort=1 : : cr HwUnit=SUP-1,AlarmPort=16
3.2 On slave DUL board
//This MO indates the ecport on slave DUL board is connected to EC B port. cr Subrack=1,Slot=1,PlugInUnit=1,EcPort=1 set Subrack=1,Slot=1,PlugInUnit=1,EcPort=1 hubPosition B //Set the slave DUL board doesn’t control the support system. set Equipment=1,HwUnit=SUP-1 supportSystemControl false
4.Others If there is only one DUL board in RBS6601,the definition of built-in ports for external alarm also can refer to this guide,only pay attention to master DUL board connection and configuration.
