The operation and maintenance of the network in general and the BSS in particular, is usually dependent upon a number of
tools, which are used to perform the actions like:
•
Configuration and integration of Network Elements and Interfaces,
•
Control of Network Element Software,
•
Alarm monitoring,
•
Fault rectification,
•
Gathering of statistics, and
•
Report generation.
The main tools available for Operations and Maintenance are:
•
OSS (NetAct),
•
BSS MML, and
•
BTS Manager
Also, there are other tools available such as Service Terminal, Wireshark etc but these are outside the scope of this
presentation.

The rapid development in telecommunications demands equipment that can be easily upgraded to
the latest standards and features. Taking the satisfaction of subscribers into account, these
upgrades must be possible without major service interruptions.
One of the advantages of a computer-controlled exchange is that new telecommunication
technologies can be easily introduced into an active exchange. To make this possible, little or no
replacement of existing hardware is needed. Most of the upgrades are realized by merely modifying
or replacing the software.
A software Build/Software Package is a combination of programs and data files that provide a
defined hardware with defined software versions. Every software package consists of so called load
modules. A file that contains code or standard data of one program block or one file block is called
a “load module”. The load modules are the smallest objects in the software configuration
management and the smallest entities of a package.
Software packages are physically stored on hard disks. On these disks, a tree of directories is
implemented like on a PC. However, disks of the network elements can have a maximum of three
subdirectory levels.
The highly developed operation and maintenance system of the DX 200, as well as its RAM-based
computer units, lay the foundation for successful software updates. Initiated by MML programs, the
software configuration management part of the DX 200 system provides the user with
sophisticated means for software updates.

DISK DIRECTORY STRUCTURE
Disk structure consist of the root and under that software package (package) directories. Usually, each
directory contains the data of one SW package. During the change delivery deployment, the files of two SW
packages are stored in the same directory. SCMANA (Software Configuration Management Directory)
subdirectory contains SOMAFI parameter file. In SOMAFI there is information about created SW-packages. The
SCMANA also occurs in the FB package when you take a fallback copy of the backup package.
There are two essential software configuration management files that are controlled by the software
configuration management:
Software configuration management file (SOMAFI) contains management information of all packages created
in the system. SOMAFI is common for all packages. It includes eight records of the same size. Each record can
contain the administration data of one created software package such as name, directory, status, package-id,
etc
Software package master list (MAFILE) is a description list of the package’s load modules and files and their
versions. Each package has its own MAFILE in BLCODE directory. By using the MAFILE, the user can create a
software package

Before you can enter MMI commands, you have to open an MML session. You can Before you can enter MMI
commands, you have to open an MML session. You can open an MML session only if you have a user
identity.
Open an MML session
a) Enter your user ID when the system asks you to (ENTER USERNAME <).
b) Enter your password when the system asks you to (ENTER PASSWORD <).
Close an MML session
a) Enter Z and a semi-colon (Z;) at the main level
To move to the main level, enter Z and a semi-colon (Z;).
Terminate an MML session
It is not recommended to use this procedure in normal circumstances. It is better to close the MML
session instead of terminating it. To terminate the MML session press BREAK. You can also press
CTRL-Y: this key combination terminates the session when you are entering your user identity or
password or typing a command at the main level; or when you have entered the command class letter
or displayed the command class menu.

All the components that are critical concerning the whole system are backed up. Redundancy is
implemented at the functional unit level identified by the recovery system.
Some functional units do not have all the states listed above. The working states of the functional units
are determined as follows:
•
The SP state can only exist with replaceable 2N or N+1 redundancy.
•
The BL state can only exist with complementary N+1 redundancy, and without redundancy.
•
The SP-RE, BL-RE, and WO-RE states can only exist if the unit can be restarted by using a
command.
•
The SP-UP state can only exist if the unit has a spare unit warm-up (computer units only).

Duplication (2N)
If the spare unit is designated for only one active unit, the software in the spare unit is kept synchronized so that taking
it in use in fault situations (switchover) is very fast. The spare unit can be said to be in hot stand-by. This redundancy
principle is called duplication, abbreviated "2N".
Replacement (N+1)
For less strict reliability requirements, one or more spare units may also be designated to a group of functional units.
One spare unit can replace any unit in the group. In this case, the execution of the switchover is a bit slower, because
of the spare unit synchronization (warming) is performed as a part of the switchover procedure. The spare unit is in cold
stand-by. This redundancy principle is called replacement, abbreviated "N+1".
Load sharing (SN+)
A unit group may be allocated no spare unit at all, if the group acts as a resource pool. The number of units in the pool
is selected so that there is a certain amount of extra capacity. If a few units of the pool are disabled because of faults,
the whole group can still perform its designated functions. This redundancy principle is called load sharing, abbreviated
"SN+".
None
Some functional units have no redundancy at all. This is because a failure in them does not prevent the function or
cause any drop in the capacity.

Some functional units have no redundancy at all. This is because a failure in them does not prevent
the function or cause any drop in the capacity.

2N
2N Redundancy (duplication) is used when two units are dedicated to a task for which one is enough
at any given time. One of the units is always active, that is in the working state. The other unit is
kept in the hot stand–by state, the spare state.
For example:
2N in Flexi BSC: OMU, GSW, MCMU
When a unit is detected faulty, it is taken into the testing state, and the fault location and testing
programs are activated. On the basis of the diagnosis, the unit is taken to the separated state, if a
fault is detected, or into use automatically, if no fault is detected.
If the spare unit is designated for only one active unit, the software in the spare unit is kept
synchronized so that taking it in use in fault situations (switchover) is very fast. The spare unit can
be said to be in hot standby. This redundancy principle is called duplication, abbreviated "2N".
N+1
Replaceable N+1 / N+M Redundancy are used when there is just one or a few spare units for a set
of N units of a given type. The spare unit is not used by the applications and is not permanently
bound to one of the N active units, but can take over the load of any one of them. When a
command–initiated changeover for a replaceable N+1 unit is performed, a pair is made up, the
spare unit is warmed up to the hot stand–by state, and changeover takes place without major
interruptions. When a unit is detected faulty, it is automatically replaced without interruptions to
other parts of the system.
For example:
N+1 in Flexi BSC: BCSU
No Redundancy
No Redundancy is needed in cases where the redundancy of a unit would not noticeably increase
the overall availability performance of the unit type.

Each alarm event, alarm and its cancellation, not filtered by the alarm system, is saved in a log file. This log
data is called alarm history. Using the AH command group commands, you can display the history data
concerning the system's alarm situation.
You can either display the alarm history, or merely the active alarms, on the selected output device.
The alarm history can be useful in troubleshooting situations. By analyzing the alarm history data you may be
able to find trends or patterns on how and when the alarms occur.

Notice
Disturbance
Disturbance is used for informing about temporary disturbance situations, which
means informing about a short failure event that does not have any permanent
effect on service
An alarm or transient disturbance marked with one asterisk
does not usually require user actions
*
**
An alarm marked with two asterisks does not threaten the operation of the
system. However, if the fault occurs during working hours, it must be corrected at
once. If the fault occurs outside working hours, it can be corrected the next day
Alarms marked with three asterisks require immediate action from the user. An
alarm like this is set when the system has become faulty to the extent that some
essential functionality of the system has stopped, or is in danger of stopping.
The maintenance personnel must take immediate action
