  • 13. Functions of DEMU
    • The DEMU is placed in slots 2 to 4 and slot 7 of the common subrack with the DATU. The DEMU is an optional module. There is maximum one DEMU under full configuration.
    • Monitoring variations in the smoke, water, temperature, humidity, infrared, and access control ,Handling alarms
    • Output of 6-route Boolean value and input of 32-route main node alarms
    DMLC DEMU CBUS3 Monitor signal
  • 14. Functions of DCSU
    • The Combined Cabinet Signal Connection Unit for DTRU BTS (DCSU) is placed in slot 5 of the common subrack, which is located in the lower part of the cabinet. There is only one DCSU and it is mandatory
    • The DCSU transfers signals for the combined cabinet and cabinet group between the common subrack and the cabinet top subrack
