Audit BDA

• This command applies to bsc objects.

• It compares the permanent parameter values of all the objects that depend on a bsc object (including created functional objects) recorded in the BSC application database (BDA) with the values recorded in the OMC-R agent operations database (BDE).

• The audit also detects the objects dependent on the bsc object that exist in the BDA but not in the BDE, and vice-versa.

• All commands for the BSC are refused during the audit, except for Display.

• If the two databases are inconsistent, the command response contains the list of the first ten objects with the parameters on which BDE-BDA differences are detected, and indicates if there are more, in which case, the audit stops.

1.6.10.4 Actions

Actions allow users to perform specific operations on objects. Only specific, radio subsystem configuration actions are described below.

The actions available only for the BSC are as follows:

• bsc objects: Build BDA 1/ Off line reset BDA / On line reset BDA.

Build BDA regenerates the BSC application database (BDA) and automatically resets the active BSC processing chain (BSC access is inhibited during the build operation).

On line reset BDA is used to configure the network with the BSC working in duplex mode from the memory copy of its BDA stored at the time the command was issued. The network is reconfigured. A Build BDA command in automatic mode is used to implement the new data, whereas in case of the use of Build BDA in commanded mode, the new data are implemented when the Activate New Version command has been executed.

Off line reset BDA resets the BSC application database (copies the prototype database into the current application database area) and automatically resets the active BSC processing chain. This command can be executed whichever is the BSC working mode, duplex or simplex.

• bsc objects: Synchronize bsc clock

This command broadcasts the OMC-R agent reference date and time to a BSC. It can be launched on several BSCs at a time.

• bscMdInterface objects: Display circular file state / Close circular file / Open circular file / Clear circular file

These commands respectively display the state, close, open, and clear a circular file which contains spontaneous messages from a BSC.

• bts object: Force HandOvers

This command redirects the traffic handled by a serving cell towards its neighbor cells. It can be launched on several cells at a time. It can be used before shutting down a serving cell in order to speed up the soft release process.

• btsSiteManager objects: Display hardware configuration

Display hardware configuration displays the configuration of ardware and is mainly used for system maintenance. It can be launched on several radio sites at a time. The BTS or BTSs that receive the message return the information to the OMC-R.

• btsSiteManager objects: Display data configuration

Display data configuration optionally displays report information related to Edge capability of the BTS and TRX configuration data.

• btsSiteManager objects: Display hardware information

Display hardware information displays detailed information on hardware of a BTS described by a btsSiteManager object (site, cell and TRX related equipment type, number, status...)

• btsSiteManager objects: Display data information

Display data information displays detailed information on configuration data of a BTS described by a btsSiteManager object (SITE data configuration display or SITE EDGE data display).

• btsSiteManager objects: Use btsSiteManager battery

Use btsSiteManager battery forces 1a BTS to use its battery if it is such equipped. The battery must operate correctly.

• channel objects: Set channel state

Set channel state is used to block or unblock a logical channel supported by a radio time slot.

• channel objects: Display channel state

Display channel state displays the states of all the logical channels supported by a radio time slot. It can be launched on several time slots

at a time. It is also used to check the results of a block command on a channel object.

• signallingLink objects: Set inhibit

This command is used to inhibit or enable an SS7 signaling link on the A interface.

Inhibiting an SS7 link stops all the traffic on the link, but the link remains in service (terrestrial traffic circuits remain preempted).

• transceiver objects: Display channel state

This command displays the states of all the logical channels supported by all the radio time slots of a TDMA frame. It can be launched on several TDMA frames at a time.

• transceiverEquipment objects: Display hardware configuration

This command displays the configuration of a TRX/DRX hardware and is mainly used for system maintenance. It can be launched on several TRX/DRXs at a time. The BTS or BTSs that receive the message return the information to the OMC-R.

Actions available only for BSC 12000HC Each action available only for the BSC 12000HC are as follows:

• bsc objects: Display chain information

Display chain information displays the state of BSC 12000HC processing chain boards (chain A or B). It can be launched on several BSC

12000HC at a time. The BSC 12000HC that receive the message return the information to the OMC-R.

• bsc objects: Kill chain

Kill chain resets one (active or standby) or both BSC 12000HC chains.

The user must confirm the command. It has the following effect:

— active chain: The chain is reset and declared as standby; the other chain is activated (switchover). Operations restart automatically but the system is not reconfigured. Class 1 DP parameters are not updated in applications, since the newly active chain is not reset.

— standby chain: The chain is reset when it can be reached. This command has no impact on operations (BSS operations are not interrupted).

— active and standby chains: Both chains are reset. The first processing chain that is operational again is declared active.

Operations restart automatically and the system is reconfigured.

Class 1 DP parameters are updated in the applications, since the newly active chain has been reset.

• bsc objects: Suicide chain

Suicide chain resets a BSC 12000HC processing chain (A or B). The user must confirm the command. It has the following effect:

— If the chain is active when the BSC 12000HC receives the command, the chain is reset and is declared standby. The other chain is activated (switchover). Operations restart automatically.

— If the chain is standby when the BSC 12000HC receives the command, it is reset when it can be reached.
