T1, T3, DS3 to OCx Circuits
T-3 line is a super high speed connection capable of transmitting data at a rate of 45 million bps (bits per second). A T-3 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 T-3 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 T-3 lines.<
An OC3 circuit is a digital line that is able to transfer large amounts of data at once. It is also known as a Optical Carrier Levels. A network line which transmits 155.52 mbps. By definition an OC3 is the equivalent of 84 T1s or 3 DS3s/T3s circuits. This is the size of the largest Internet backbone providers networks. It is one of the most powerful communications signal available today. It is used for transmission and receiving of huge amounts of Data. Please take a look below at some of the various speeds available for an OCx circuit.
OC-1 = 51.85 Mbps
OC-3 = 155.52 Mbps
OC-12 = 622.08 Mbps
OC-24 = 1.244 Gbps
OC-48 = 2.488 Gbps
OC-192 = 9.952 Gbps
OC-255 = 13.21 Gbps
