INTRODUCTION
OBJECTIVE OF TRAINING
For a number of years, it has become the fashion as well as need
to develop your
skills in technical exploration and ingrains in you as a habit . This
habit becomes your lifelong ally in the race to stay on top of the
situation. In the ever-changing industry, the ability to explore
and assimilate new knowledge is vital. Therefore, for making us up
to date, confident, self-reliant, potential power to cope with the
problems creatively and introducing us to the live, real practical
scenario of the programming world and also bringing many
interesting experiences in its wake which aims at imparting
quality technical knowledge and education and innate talent with
experiences, the college organized a project centric curriculum in
the form of summer training which was really progressive to
achieve the desired excellence in implementation of learning and
self-confidence.
COMPANY OVERVIEW
Bharat Sanchar Nigam Limited(BSNL) is one of the major telecom

SDH CONCEPTS
INTRODUCTION
Synchronous Digital Hierarchy (SDH) signals the beginning of a new
phase in the evolution of the world’s communication network. SDH will
bring a revolution in telecommunications services which will have far
reaching effects for end-users, service-providers and equipment
manufacturers alike. With the introduction of SDH, the transmission
network will enter a new era which can be compared in scale to that
occurred following the introduction of PCM and Optical Fibre.
As end-users (particularly business-users) become more dependent on
effective communication, pressure builds up for a reliable and a
flexible network with unlimited bandwidth. The complexity of current
network, based on plesiochronous transmission systems, meant that
network operators are unable to meet this demand.
The current Plesiochronous Digital Hierarchy (PDH) evolved in
response to the demand for plain voice telephony (sometimes called
POTS- Plain Old Telephony Service) is not ideally suited to the
efficient delivery and management of high bandwidth connections.
Synchronous transmission systems address the shortcomings of PDH.
Using essentially the same fibre, a synchronous network is able to
significantly increase available bandwidth while reducing the amount of
equipment in the network. In addition the provision within the SDH for
sophisticated network management introduces significantly more
flexibility into the network.
