Cisco Certified Technician Latest Update Graded A+ ATM (Asynchronous Transfer Mode) The international standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media, such as E3, SONET, and T3. Bandwidth The difference between the highest and lowest freq...
