What does Dial-Up Connection mean?

A dial-up connection uses a standard phone line and an analog modem to access the Internet at data transfer rates (DTR) of up to 56 Kbps.

It is considered as the least expensive way to access Internet however, it offers one of the slowest connection.

We must keep in mind, that a dial - up connection is established when two or more communication devices rely on a public switched telephone network ( PSTN ) to connect with an Internet Service Provider, also called as ISP.

ISPs are a boon for many subscribers especially for the one, who are budget conscious, because it often offers free dial up connections.

When we talk about a leased line we must be mindful of the fact, that it is a dedicated fixed -bandwidth data connection. Since the connection is rented by the Internet Service Providers directly to the business , so the term leased has been incorporated.

A leased line must be symmetrical, uncontended & it has to be from point to point.

Differences between dial-up (modem) connection and leased line connection:

Dial-up (modem) connection:

• A Dial-up connection is not always active.
• A Dial-up connection is asynchronous communications.
• It is less costly.
• It is commonly used by Home User.

Leased line connection:

• A leased line connection is always active.
• A leased line connection is synchronous communications.
• A leased line connection is costly, user-pay rent to service provider.
• It is commonly used in Offices & Business.

What’s the difference between a leased line and broadband?

A leased line is a dedicated, uncontended connection between your premises and the local exchange. It’s  meant only for your business.
