Bharti Airtel and Alcatel-Lucent managed services joint venture for broadband and telephone services : ALNMSI
Paris and New Delhi, April 30, 2009 -
• JV manage Airtel’s migration to next generation networks to offer advanced services like high-speed internet, triple play, media-rich VAS, MPLS, VPN for both retail and business customers
• First managed services partnership for broadband and telephone services in India
• Under the joint venture, Alcatel-Lucent will design, plan, deploy, optimize and manage Bharti Airtel’s broadband and telephone network across India.
Telecommunication
• It refers to information (like-Signals, Images, Data, Voice etc) between any two points via a medium(like-Copper wire, Cable, Directional radio links, Satellites, Optical fiber etc).
• Communications – activity associated with distributing or exchanging information
• TELEPHONY - refers to the exchange of speech / voice information between subscribers connected by pairs of wire.
Classification of Telecommunication
• Transmission – transfer of speech and signaling information
- unrestricted propagation
- restricted propagation
• Switching – establishes a connection between two points
- connection
- signaling
Telecom System
• The basic problem
– Telephones introduced in late-1800’s.
– Initially each telephone was directly connected to another site.
• This led to an explosion of direct connections
(n*(n-1)/2)
• This lead to the need to “switch” the connections.
• Over the years many different ways to request (or “signal”) a certain endpoint
– Voice commands to live operator
– Rotary dial
– Touch tone
• And many different ways to make the desired connections
– Electromechanical methods
– Computer controlled systems
All have the goal of connecting two parties together so that they can communicate
Telecom Networks
How can communication be established ?
- In same locality -> in app. Geographical location
- In different localities -> in form of network
Thus the infrastructure including all the hardware & software
allowing the interconnection of users for exchange of
information is called the Telecom Network.
