MCITP MCSE : Security Specialist ATM To transmit data Asynchronous Transfer Mode uses fixed sized packets of 53 bytes long called cells and provides data transfer rates from 25 Mbps to 2400 Mbps. ATM can be used with twisted pair and fiber optic cabling. By using standard sized cells, ATM can provide constant, high-speed data streams that audio, video, and imaging applications require. Frame Relay Frame Relay is a WAN technology, connection speeds range from 56 Kbps to 1.544 Mbps using a T1 carrier service, and speeds up to 45 Mbps using a T3 carrier service. Frame relay is a packet switched networking protocol. To connect two or more LANs using Frame Relay, a company must lease one dedicated access line to the Frame Relay network for each LAN. Frame Relay access lines often use a T1/ E1 line. Sonet/SDH Synchronous Optical Network, is a standard for optical telecommunications transport. It was formulated by the ECSA for ANSI, which sets industry standards in the United States for telecommunications and other industries. The comprehensive SONET/synchronous digital hierarchy (SDH) standard is expected to provide the transport infrastructure for worldwide telecommunications for at least the next two or three decades. T1/E1 A 1.544 Mbps point to point dedicated, digital circuit provided by the telephone companies. T1 lines are widely used for private networks as well as interconnections between an organizations LAN and the telco. A T1 line uses two pairs of wire one to transmit, and one to receive. and time division multiplexing (TDM) to interleave 24 64-Kbps voice or data channels. The standard T1 frame is 193 bits long, which holds 24 8-bit voice samples and one synchronization bit with 8,000 frames transmitted per second. T1 is not restricted to digital voice or to 64 Kbps data streams. Channels may be combined and the total 1.544 Mbps capacity can be broken up as required. T3/E3 A T3 line is a super high-speed connection capable of transmitting data at a rate of 45 Mbps. A T3 line represents a bandwidth equal to about 672 regular voice-grade telephone lines, which is wide enough to transmit 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, universities with high-volume network traffic and for the backbones of the major Internet service providers.
