INTRODUCTION
LANDLINE
• A landline telephone (also known as land line, land-line, main line, and fixed-line) refers to a phone which uses a solid medium telephone line such as a metal wire or fiber optic cable for transmission as distinguished from a mobile cellular line which uses radio waves for transmission.
HISTORY
• The invention of fixed line came into existence with the invention of telephone in the year 1876 by an eminent scientist of U.K ALEXANDER GRAHAM BELL.
• 26 August 1854 — Charles Bourseul published an article in the magazine L'Illustration (Paris): "Transmission électrique de la parole" (electric transmission of speech), describing a 'make-and-break' type telephone transmitter later created by Johann Reis.
• 6 April 1875 — Bell's U.S. Patent 161,739 "Transmitters and Receivers for Electric Telegraphs" is granted. This uses multiple vibrating steel reeds in make-break circuits.
DEVELOPEMENT
• Alexander Graham Bell's invention was based on the electric telegraph. Several different telephone designs appeared shortly after Bell's, but they were all landlines, connected through transmission wires. Once telephones became common, central operating switchboards appeared in which physical connections were made by operators so that telephone users could talk to one another.
TECHNOLOGY• Landline telephones, from Bell's onward,
operated on the principle of electrical resistance. When a user speaks into a landline phone's handset, he activates a microphone that sends an electrical current through a pair of insulated wires.
• The current follows a physical course, passing through a telephone exchange, where it is re-transmitted to the listener on the other end of the connection and converted to sound. Even "wireless" phones using landline networks employ a physical connection, replacing the cord between the phone and the handset with a radio signal.
DECLINE
• Digital telephone signals were introduced in the 1960s and began to replace analog signals. Cellular networks appeared in the 1970s, using a modem to transmit a telephone signal without the use of a wired network. Cell phones were approved by the Federal Communications Commission and became available to the public in the 1980s, though quality was generally poor and usage was expensive.
• In the late 1990s, a new generation of cell phones made use of new digital network technology, replacing many private landlines and bringing telephone service to parts of the world where landlines never were installed.
ADVANTAGES
• Even with cell-phone use on the rise and landline use declining, landline telephones do present advantages over cell phones. The biggest advantage is consistent fidelity of the telephone signal.
• Landlines don't suffer from the signal problems cell phones face during bad weather or in remote areas. Landline telephones do not require an electrical connection and are operational during power outages--whereas cell phones rely on relay towers that must be powered to receive or send a signal.
DISADVANTAGES
• The biggest disadvantage to landline telephones is their immobility. While cell phones can be taken and used almost anywhere, landline phones can be used only in or near the home or office.
• The landline may represent a redundant service and an added cost for those with a cell phone, though most basic landline service packages cost less than basic cell-phone plans. Landline phones are quickly losing their quality advantage as cell phones' audio signals and reliability improve.

TARRIF PLANS
• Tarrif plans are subjected to change according to the regions
• Within a single region there may be more than 10 different tarrif plans available by a single service provider
• For the sake of simplicity I have compared tarrif plans by different service providers in the delhi-ncr region

TYPES VALUE ADDED SERVICES
• Call forwarding (or call diversion) is a feature on some telephone networks which let an incoming call to a called party to be redirected to a third party. For example, the third party may be a mobile telephone, voicemail box or other telephone number where the desired called party is situated.
• Three Party Conference adds a third party to an existing call, allowing you and the other two parties to speak together in a three-way conference.
• PARALLEL RINGING With parallel ringing you will never miss a call even when you’re away from your fixed line. Share your fixed line number and get incoming calls simultaneously on two phones - your landline and your mobile.The ringing stops on the other line as soon as you pick up any one phone.So never miss a call now.
• CALL RESTRICTION With Call Restriction you can manage chargeable calls (calls that are outside your calling area, 0900 services or mobile calls) made from your home phone.

VALUE ADDED SERVICES
INTERNET SERVICES
• Internet services was the second major use of fixed line which was earlier used only to provide telephone services.
• In the earlier times till 2005 the speed of internet using fixed line was very low i.e. 32kbps or 64kbps (compare to the broadband speed of 256 kbps).
• Later after 2005 high speed internet plans i.e 2Mbps or above were introduced by different service provider but the cost was very high.
• Today the speed upto 5Mbps can be obtained from the same copper wire used in fixed line services.
