Bits Per Second (bps)
A measure of data transmission speed over communication lines based on the number of bits that can be sent or received per second. Bits per second-bps-is often confused with bytes per second-Bps. 8 bits make a byte, so if a wireless network is operating at a bandwidth of 11 megabits per second (11 Mbps or 11 Mbits/sec), it is sending data at 1.375 megabytes per second (1.375 MBps).
C
Circuit The path over which voice or data transmission travels. Circuit can be twisted-pair cables, coaxial cables, fiber optic cables, or microwave transmissions.
D
DSL DSL provides a dedicated service over a single telephone line. SDSL carries data at 1.54 Mbps upstream and downstream. This is a best option for small organizations where bandwidth requirements are not mission critical.

Fractional T1 A portion of a T1 circuit. A full T1 allows transmission at 1,544,000 bits per second (1.544 Mbps). A fractional T1 circuit allows transmission at lower speeds of 384 Kbps, 512 Kbps, or 768 Kbps.
Frame Relay Frame relay is a telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks (LANs) and between end-points in a wide area network (WAN). Frame relay puts data in a variable-size unit called a frame and leaves any necessary error correction (retransmission of data) up to the end-points, which speeds up overall data transmission

ISDN Integrated Services Digital Network is a set of standards for digital transmission over ordinary telephone copper wire as well as over other media. Home and business users who install an ISDN adapter (in place of a modem) can see highly-graphic Web pages arriving very quickly (up to 128 Kbps). ISDN requires adapters at both ends of the transmission so your access provider also needs an ISDN adapter.

OC3 and Up An OC line is an optical line with varying bandwidth of up to 10Gbps. This is the connection that the ISPs and large corporations need to run their business. If your business needs reliable, dedicated bandwidth at the fastest speeds available, then an OC line is your answer.

T1 line - Burstable/Metered A burstable T1 line is a full T1 that allows you to pay for what you use. Burstable T1 lines carry bandwidth up to 1.54 Mbps and are more cost effective if you only need maximum capacity a few times a month.
T1 Line A T1 line is a high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bps (bits per second). A T1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. A T1 line is a high-speed digital connection capable of transmitting data at a rate of approximately 1.5 million bps (bits per second). A T1 line is typically used by small and medium-sized companies with heavy network traffic. It is large enough to send and receive very large text files, graphics, sounds, and databases instantaneously, and is the fastest speed commonly used to connect networks to the Internet. Sometimes referred to as a leased line, a T1 is basically too large and too expensive for individual home use.
T3 Line A T3 line is a super high-speed connection capable of transmitting data at a rate of 45 million bps (bits per second). A T3 line represents a bandwidth equal to about 672 regular voice-grade telephone lines, which is wide enough to transmit full-motion, real-time video, and very large databases over a busy network. A T3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic.

A T3 line is typically installed as a major networking artery for large corporations and universities with high-volume network traffic. For example, the backbones of the major Internet service providers are comprised of T3 lines.
