1. Operation status of modules

Access: [Maintenance/Module State]

Functions: display the communication state between the

maintenance console and each BM of the BSC

Results:

in normal conditions, module numbers will be displayed.

If the communication is faulty, a * will be placed before the

module.




2. Operation status of boards

Access: [control/Equipment]

Functions: view and query board state and information,

reset board

Results :

in normal conditions, boards on the interface are in grey,green (active) and blue (standby).

if the board is faulty, color shown on the panel will

change to red.

Caution: if you find a board is in red, first you should confirm it has been

configured or not, then for GALM in AM you should check whether connected

alarmbox has been powered on.




Query MPU




Query GCKS




3. CPU occupation status

Access: [trace/occupation ratio]

Functions: by viewing CPU occupation ratio, the BSC load

condition (Normal, Overload and Congestion) can be known.

Results:

In normal conditions, the occupation status of CPU andmemories should be displayed in the system performance

tracing window. When the bar chart is blue, the status is

normal.

If the bar chart is yellow, the status is overloaded and red,

congested.



Check equipment status




4. Status of CCS7 links Access: [SS7 Maintenance/State Query] Functions: query the signaling link state, destination state and

route state to ensure the interworking of inter-office SS7 Interface:

Module number Link number




Query input parameters

Data configuration \ view data configuration work mode\Module 0 \ Hardware \ [E3M Board property]




Results:

In normal conditions




5. Status of LAPD links Access: [Control\LAPD Link Maintenance]

Functions: query LAPD link to check current link state

Interface:

Module number

Start link no, end link no





Data management\site\[site description table]---OML





Data management\local-office\[TRX configuration table]---RSL



Check equipment state

Results: In normal conditions, the query result should be multi frame

establish state

If TEI has not allocate state, the link has not been

configured; If TEI has allocated state, the link has been

configured, but board is not inserted; if off-link state, theestablished link is disconnected and system cannot operate

at that time. Or the link is configured and board is inserted,

but they are not connected to the BTS

6. Circuit status Access: [ control\circuit\circuit state]

Functions: query the state of channel of TC, BIE and PBIE circuits

Interface:

Module number

Circuit type

Start channel, end channel



Internal Use


Results:

In normal conditions, state should be uninstalled, idle and busy

3. switchover Access: [control\immediate switchover]

Functions: when the active board is faulty or the data of

active/standby boards are inconsistent, if the boards have not

switched over automatically, it is required to switch over the

active and standby boards immediately, making the normalboard use the correct data and ensure the correctness of the

BSC operational data. After the active and standby boards are

switched over immediately, the original standby board will

become the active board while the original active board become

the standby board

4. board resetting Access: [control\equipment]

Functions: resetting operations are be performed when some

boards are faulty. Resetting results include “successful reset”,

“equipment fault”, ”uninstalled”, “the device can’t be reset” or

“unexecuted”

Caution: This operation requires the system setup authority. Do not reset a board

unless it is necessary.

5. module resetting Access: [control\hierarchical reset]

Functions: mainly used to load some modified data that can not

be set online, or as a way of recovery when any problem occurs

during BSC running

Caution: Hierarchical reset operation requires system setting authority. This operation mayaffect system services. Do not perform this operation unless it is necessary.
