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 Basics.3 ATM Model.3 ATM Headers.3 ATM Addressing.5 Cisco ATM Addressing.5 ATM Adaptation Layer.5 Quality of Service.6 Service Categories.6 Frame Relay Basics.7 Voice Basics.8 Analog to Digital Conversion.9 Optimization.9 Signaling.10 General Installation.12 Tools Required.12 Installation Outline.12 Command Line Interface CLI .13 BPX 8600 Series.17 Card Types.17 Installing BPX Cards.17 Initial Configuration.20 IGX 8400 Series.22 Card Installation.22 Initial Configuration.26 MGX Series Installation.29 MGX 8220.29 Card Installation.30 Initial Configuration.32 MGX 8850.32 Card Installation.33 2001 All Rights Reserved - BrainBuzz.com 1 TM Cramsession Cisco WAN Switching Certification ÖrainÖUZZ.COnL MGX 8850 Interface Cards.35 Initial Configuration.38 Cisco WAN View.38 Cisco Wan Manager CWM .40 Components.40 Additional Features.41 Software and Firmware Upgrades.42 Downloading from CWM workstation.43 Download from a Switch.43 2001 All Rights Reserved - BrainBuzz.com 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.
