56 kbps is ISDN (Integrated Services Digital Network), which uses a switched circuit to connect from point to point.
45 Mbps is probably DS3.
56Kbps
It has to do with a few issues, one of which is the SNR and signal clarity that can be acheived by sending tones down a plain old telephone line. There is just not enough bandwidth in a POTS connection to support higher rates of data flow as well.
At 56Kbps, a 7B file would take approximately 1.07 milliseconds to download.

VOIP is Voice Over Internet Protocol. It is a technique for converting an analog telephone connection to digital, sending it over a computer network, and converting it back to analog at the other end. The typical bandwidth required for a telephone conversation is 56kbps. In fact, this is how the telephone companies work. What we call VOIP is an extension of that technology to allow use within a business, or to allow telephone calls over the Internet. In a business application, the network architecture usually supports a QOS (Quality of Service) parameter that gives precedence to VOIP traffic over data traffic. Often, with Internet telephone support, the QOS is not set nor supported, making the conversation subject to breaking up. Just like some cellphones.

To be able to view live TV using a 56 Kbps modem Internet connection, you must find a stream that downloads at 56k/s or less for it to be 'live'. However, quality would be very, very, low.
A dialup service connects to the Internet through a phone line with a maximum speed of 56kbps. Broadband refers to a connection that has capacity to transmit large amount of data at high speed. Presently a connection having download speeds of 256kbps or more is classified as broadband.
well if you have 56kbps, i took 350kb divided by 56kbps (kilabytes per second) i get about six and a half minutes to download, real world might be interference such as a wall, door ect. or if you have a wireless connection it may depend on your signal strength.
Broadband In general, broadband refers to telecommunication in which a wide band of frequencies is available to transmit information. Because a wide band of frequencies is available, information can be multiplexed and sent on many different frequencies or channels within the band concurrently, allowing more information to be transmitted in a given amount of time (much as more lanes on a highway allow more cars to travel on it at the same time). Related terms are wideband (a synonym), baseband (a one-channel band), and narrowband (sometimes meaning just wide enough to carry voice, or simply "not broadband," and sometimes meaning specifically between 50 cps and 64 Kpbs). leased line A permanent telephone connection between two points set up by a telecommunications common carrier. Typically, leased lines are used by businesses to connect geographically distant offices. Unlike normal dial-up connections, a leased line is always active. The fee for the connection is a fixed monthly rate. The primary factors affecting the monthly fee are distance between end points and the speed of the circuit. Because the connection doesn't carry anybody else's communications, the carrier can assure a given level of quality. For example, a T-1 channel is a type of leased line that provides a maximum transmission speed of 1.544 Mbps. You can divide the connection into different lines for data and voice communication or use the channel for one high speed data circuit. Dividing the connection is called multiplexing. Increasingly, leased lines are being used by companies, and even individuals, for Internet access because they afford faster data transfer rates and are cost-effective if the Internet is used heavily.
The GPRS modem has a much greater bandwidth. It would be better suited to most tasks. However it would depend on what the connection was intended for. The wired modem may provide better reliability and lower ping in some situations.
broadband satellite is an alternative for customers who cannot get cable or DSL connections A satellite connection does not require a phone-line or cable, but uses a satellite dish for two way communication, download speeds are up to 500kbps: uploads are closer to 56kbps it takes time for the signal from the satellite dish to rely to your internet service provider (isp) through the satellite orbitting the earth.
