  • A leased line is a dedicated ,pemanent connection between two sites that run through the telephone network.Typically, leased lines are used by businesses to connect geographically distant offices. Unlike normal dial-up connections, a leased line is always active.

    Leased line are of two types:

    Analog and digital

    All the lines like T-1, T-2 all T's comes under digital leased lines

  • Hey Sunil,

    You are wrong. Telephone lines can never be leased lines as they are assigned dynamic IP Address when they are in the local network. In Leased line, static IP Address is assigned.

    Also, if you have dynamic IP Address, its never possible to have dedicated circuilt between 2 computers across network.

  • sorry buddy.
    but i would like to correct you.

    you might have heard of circuit switching.
    & if yes, then you might be knowing that, in circuit switching, both temporary & permanent(leased) connections are made based upon the request.
    since circuit switching is used in telephony, then offcourse telephone lines are leased 1s.

    if you still have doubt, refer to DCN by furozon

  • heres what wiki has to say

    A leased line is a symmetric telecommunications line connecting two locations together. Unlike traditional PSTN lines they do not have a telephone number, each side of the line being permanently connected to the other. They can be used for telephone, data or Internet services.

    In the U.K., leased lines are usually available at speeds of 64k, 128k, 256k, 512k, 2M and provided to the customer on X.21 presentation. Higher speeds are available on alternative interfaces.

    In the U.S., low-speed leased lines (56 kbit/s and below) are usually provided using analog modems. Higher-speed leased lines are usually presented using FT1 (Fractional T1): a T1 bearer circuit with 1 to 24 56k or 64k timeslots. The customer must manage their own network termination equipment—Channel Service Unit or Data Service Unit (CSU/DSU).

    For many purposes, leased lines are gradually being replaced by DSL links.

  • hey buddy,

    all these threads are running in indian context, so its assumed that answers are supposed to be for indian viewers of this thread.

    and in india, there is no provider, for sure because am in this business (designing softwares) that provides permanent switch on telephone, including WLL operators.

    So in Indian context, my answer is totally correct and you might be right when you are referring to US conditions.

    also, when permanent connections are provided, it no longer remains PSTN or POTS and it becomes some kind of digital network, which again breaks the law of Telephone systems.

    So its totally upon you and viewers which option to choose.
