1 : Presentation of the BTS Terminal Presentation

The BTS Terminal software runs under the WINDOWS platform and provides local access to the BTS

It performs local management functions such as :

Alarm monitoring

Event monitoring

States

System behaviour observation

Initiate action

View reports related to actions

2 Definition and Handling of the SBL

1.16

2 : Definition and Handling of the SBL Session presentation

Objective : to be able to handle theSecurity Blocks (SBL)

Program :

2.1 Definition

2.2 SBL states

2.3 SBL Hierarchy

2.4 Operator Commands

2.5 Relationship between SBL & RIT

1.17

2 : Definition and Handling of the SBL Definition

Security Block (SBL) 1/2

An SBL represents an entity of the BSS which is manageable by the O&M, it can be: an equipment (e.g. RA) a resource (e.g. BTS_TEL) A support resource (e.g. RSL)

One SBL can be carried by several RITs Example: SBL RA

One board can carried several SBLs Example: SBL SUMA board

1.18


Security Block (SBL) 2/2

A SBL is identified by the following parameters

Unit type (e.g.: “BTS”) Unit number (e.g.: 1…255) SBL type : this is the name of the SBL (e.g.: “TRE”) SBL number SBL sub number: (represents the number of a SBL

which is part of another SBL.)

1.19


Replaceable Item (RIT)

An RIT is the smallest physical module that can be replaced in case of fault. (can be a board for example)

An RIT is identified by the following parameters: Unit type Unit number Rack Shelf Slot

1.20

2 : Definition and Handling of the SBL SBL States : Description

Human operation

OPR (OPeRator) The object is subject to an operator intervention It cannot perform its functions

Level of service

IT (In Traffic) The object is ready to perform all its functions The provided service is acceptable

FIT (Faulty In Traffic) The object is ready to perform its functions in a degraded mode A non fatal error has been detected The provided service is acceptable

1.21


Level of service

FLT (FauLTy out of service) A fatal error has been detected The service is unavailable The provided object has the capability to recover autonomously

FOS (Forced Out of Service) A fatal error has been detected The service is unavailable The provided object does not have the capability to recover

autonomously

UT (Under Test) The object is being tested by automatic processes The service is momentary unavailable

1.22


Inhibition due to system administration

SOS (System Out of Service) The object cannot perform its functions because a parent object is

out of service

EF (External Failure) The object cannot perform its functions because another co-

operating item is out of service

1.23


Configuration management

NEQ (Non EQuipped)

WTC (Wait for Traffic Clear) This state is linked with the WTC timer parameter Corresponding SBL cannot be selected for new transactions The traffic still goes on until the WTC timer expires

MSD (Maintenance SeizeD) This state indicates that a test operator action is running on the

corresponding SBL

MSD AUTO (Maintenance Seized Autonomously) This state indicates that an action autonomously triggered by the

system is running on the corresponding SBL

1.24

2 : Definition and Handling of the SBL SBL States

To display the state of BTS SBLs, use the following menu:

Monitoring → BTS Modules

1.26

2 : Definition and Handling of the SBL SBL Hierarchy : Interdependencies

Case (1)

A is in IT/FIT state if B is in IT/FIT state

A is in SOS state when B is faulty (FLT, FOS, OPR, SOS, EF)

Case (2)

A is in IT/FIT state if at least B or C is IT/FIT state

A is SOS state when B and C are faulty (FLT, FOS, OPR, SOS, EF)

2 : Definition and Handling of the SBL SBL Operator Commands

Handling of SBL

To ensure the maintenance of the BTS, the operator needs to check or modify the SBL conditions from the BTS-Terminal.

Using the menu

Commands → SBL Management

1.29


Maintenance operator commands

Read : to get the SBL State

Init : It allows the setup of a functionality. This command applies to an SBL which was disabled before

PurposeReactivate the functionality of a target SBL

ImpactWhen the initialisation has been successfully

achieved, the SBL should be able to handle its functionality

1.30



Disable : It allows to kill the functionality of an SBL

Purpose Inhibit the functionality of a target SBL and filters

alarmsThe Wait Traffic Clear parameter introduces a delay

into the command executionThe traffic may be stopped in a clean way

ImpactThe context is lost (calls / signalling)

1.31



Restart : It allows to restart a functionality

PurposeBuild up a function supported by SW without SW

download Impact

Context is kept

1.32



Reset : It allows to kill and set up a functionality in sequence

PurposeEscape from a situation where the behaviour is

doubtfulThis command may be seen as a combination of

Disable and Init Impact

SW and DATA downloading.The context is lost (calls / signalling)
