Operation and Maintenance Support
The supervision parameters are defined by the IDB or the OMT. The
supervision parameters define supervision status (active/inactive) and
test interval. Each parameter has a default value. When the test loop is
activated the test is continuously repeated with the defined test interval.
The supervision is terminated at deactivation from the Operation and
Maintenance Terminal.
Detected faults at RF Loop Test are handled by the Diagnostics and
Fault handling functionality.
The default values are:
Supervision status: active
Test interval: 5 minutes
38.10 Calendar Time Request
Purpose
To update the system time.
Preconditions and Initiation
The RU Mode should be Remote. The Calendar Time Request function
is initiated five seconds after the OML for CF has been established, and
when RU Mode is switched from Local to Remote.
Description
All main RUs handle a real time clock which is internally used within
the RUs as the system time. The system time is updated by the
Calendar Time elementary procedure on Abis interface. Calendar time
is distributed to all main RUs. System time is then updated for those
RUs. Calendar time is periodically requested and updated while layer 2
communication link is established. The request interval is 24 hours.
The Calendar Time request function is terminated when OML for SO
CF is released and stopped and when RU Mode is switched from
Remote to Local.
38.11 RSSI Temperature Compensation
Purpose
To be able to update the RSSI temperature compensation value.
Preconditions and Initiation
Applicable for any RBS operational state. The TDMRU (TRU) Mode
should be Local or Remote. The RSSI Temperature Compensation is
initiated by the Internal Configuration function in the Restart and
Recovery sequence.
Description
The loss in the receiver path varies with the temperature. In order to get
a more accurate estimate of the loss, the temperature for the receiver
