   Dronacharya Group of Institutions, Greater Noida organized one day Industrial Visit to Advanced Level Telecom Training Centre (ALTTC), BSNL,   Raj Nagar, Ghaziabad on 08th April 2015. ALTTC aspires to be one of the   most trusted, technologically advanced and valued telecom training   centre in the world with mission to deliver excellence through training. Dr. Santanu Koley, Associate Professor, CSE Department along with third and fifth semester student of Computer Science & Engineering department of DGI, Greater Noida, attended the Industrial Visit enthusiastically. 
 The objective of the visit was to enhance the knowledge & skills of   the participants regarding use of Networking and Data Transmission in   India and abroad. The students were given an overview of the Telecom   systems and how Voice and Data are carried in a Telephone Network during   the industrial visit.
The   visit started with technical lecture on Data transmission by ALTTC   officials. The session started with the discussion on communication   technology used by BSNL all over India with the emphasize on global   scale on network technology. ALTTC official   further explained   functions of call detail record room, call tracing technology,   installation and execution procedure on various hardware platforms.    Queries raised by student related with technical session were wisely   answered by the resource persons.
After the lecture, students were divided into small groups and taken to ALTTC Lab by trainers for providing hands on experience. Trainers presented a   brief description of various technologies being used in Network hardware   at the centre. They discussed about IPv4, IPv6,    WI-FI, Routers, hubs   and cablings including fibre optic inside the lab.
The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g.   Ethernet). IPv4 provides an addressing capability of approximately 4.3   billion addresses. The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4. The most   obvious improvement in IPv6 over IPv4 is that IP addresses are   lengthened from 32 bits to 128 bits. IPv6 also supports   auto-configuration to help correct most of the shortcomings in version   4, and it has integrated security and mobility features. This extension   anticipates considerable future growth of the internet and provides   relief for what was perceived as an impending shortage of network   addresses. A router is a device that forwards data packets along   networks. A router is connected to at least   two networks, commonly two LANs or WANs or a LAN and its ISP's network.   Routers are located at gateways, the places where two or more networks   connect.
ALTTC   official also explained about basics of Network technology,   architecture & routing fundamentals & protocols, IT security at   IP/DATA/LAN /WAN networks and installation procedure of network devices.   In the end, queries of students were answered by officials of ALTTC   (BSNL). 
The Industrial Visit to ALTTC (BSNL) training centre was highly informative, as it provided an insight into   the real working environment of the industry and created awareness about   Integrated Technology used by the company. The programme enables the   students to apply their classroom learning to a real-life situation   while being mentored by a variety of industry experts.
