Transmission types
•
Asynchronous transmission
•
Plesiochronous transmission
•
Synchronous transmission
Asynchronous transmission
Asynchronous
transmission is transmission of data in which time intervals between
transmitted characters may be of unequal length. Transmission is controlled by
start and stop bits at the beginning and end of each character. Transition of
signals do not occur at the same nominal rate Generally free running quartz
oscillators derive the clock, there is no timing pulses sent from transmitter
to receiver
Plesiochronous transmission
Plesiochronous
is a Greek word meaning Almost Synchronous, but not fully synchronous.
The digital transitions in the signals occur at almost the same rate. There may
be a phase difference between the transitions of the two signals, and this
would lie on specified limits.
Synchronous transmission
The
digital transitions in the signals occur at exactly the same rate. There will
be no phase difference between the transitions of the two signals, and this
would lie on specified limits. In a synchronous network, all the clocks are
traceable to one primary reference clock (PRC). The accuracy of the PRC is
better than 0.1 in 1011 and is derived from a cesium atomic standard.
Multiplexing
It is
the process of combining a number of individual channels into a common
frequency band or into a common bit stream for transmission.
Different
multiplexing techniques are:
•
Frequency Division Multiplexing (FDM)
•
Time Division Multiplexing (TDM)
• Wavelength
Division Multiplexing (WDM)
Frequency Division Multiplexing
FDM
is a process in which the bandwidth is divided in frequency domain, or in other
words each of the input signals is transmitted at a different frequency
(Carrier) but simultaneously (or in the same time slot). FDM is a multiplexing technique used for
analog signals.
Time division multiplexing
TDM
is a type of multiplexing in which different signals are multiplexed in
different time slots. In TDM each time slots is fixed for different signals
sequentially. TDM uses full bandwidth for every channel, but not at the same
time so that every channel gets its time slot in the shared line.
Wavelength division multiplexing
It is
a type of multiplexing in which different signals are multiplexed at different
wavelengths for full time slots. When each wavelength is multiplexed from
different TDM signals then the multiplexing is called TDM over WDM. WDM is
widely used for the following reasons:
•
Better utilization of fiber
• Low
unit cost of bandwidth in high capacity systems
• Easily integrated with existing
equipment in the network
Network Management Subsystem (NMS)
The Network Management Subsystem (NMS) is
the third subsystem of the GSM network in addition to the Network Switching
Subsystem (NSS) and Base Station Subsystem (BSS), which we have already
discussed. The purpose of the NMS is to monitor various functions and elements
of the network.
The functions of
the NMS can be divided into three categories:
·
Fault
management
·
Configuration
management
·
Performance management
These functions
cover the whole of the GSM network elements from the level of individual BTSs,
up to MSCs and HLRs.
Fault
management
The purpose of
fault management is to ensure the smooth operation of the network and rapid
correction of any kind of problems that are detected. Fault management provides
the network operator with information about the current status of alarm events
and maintains a history database of alarms.
The alarms are
stored in the NMS database and this database can be searched according to
criteria specified by the network operator.
Configuration management
The purpose of
configuration management is to maintain up-to-date information about the
operation and configuration status of network elements. Specific configuration
functions include the management of the radio network, software and hardware
management of the network elements, time synchronization, and security operations.
Performance management
In performance
management, the NMS collects measurement data from individual network elements
and stores it in a database. On the basis of these data, the network operator
is able to compare the actual performance of the network with the planned
performance and detect both good and bad performance areas within the network.
