ATM is a packet-switched technology based on a 53-byte packet called a cell. Each cell is divided into a 5-byte header and a 48-byte payload. The short, fixed length cell reduces delay and jitter, allowing time sensitive information such as voice and video to be transported along with data. There are various transmission media and rates available with bandwidth measured in megabits to gigabits. | TM Cramsession Cisco WAN Switching Certification brainhuzzconv Contents Contents . 1 ATM ATM ATM ATM Cisco ATM ATM Adaptation Quality of Service Frame Relay Voice Analog to Digital General Tools Installation Command Line Interface CLI .13 BPX 8600 Card Installing BPX Initial IGX 8400 Card Initial MGX Series MGX Card Initial MGX Card 2001 All Rights Reserved - 1 TM Cramsession Cisco WAN Switching Certification MGX 8850 Interface Initial Cisco WAN Cisco Wan Manager CWM .40 Additional Software and Firmware Downloading from CWM Download from a 2001 All Rights Reserved - 2 TM Cramsession Cisco WAN Switching Certification ATM Basics ATM is a packet-switched technology based on a 53-byte packet called a cell.

Similar to the OSI model B-ISDN uses a seven-layer model. ATM redefines the lower 3 layers into the Physical Layer the ATM Layer and the ATM Adaptation Layer.
