tailieunhanh - The Avidia Advantage Series Subtending: Reduce Equipment Cost and Complexity

In today’s competitive telecommunications environment, you are faced with the challenge of minimizing the cost and complexity of equipment at the network edge. To meet this need, the ADC Avidia Integrated Access Switch (IAS) combines the functionality of an ATM edge switch with a DSLAM. Then, through subtending, in which several systems are viewed and managed by a single management platform, deployment of Avidia allows you to lower equipment and network management costs. Avidia concentrates multiple traffic streams to a single network uplink, enabling the elimination of expensive ATM edge switches. By reducing the number of network elements, you can reduce the number of element management systems,. | The Avidia Advantage Series Subtending Reduce Equipment Cost and Complexity white paper Executive Summary In today s competitive telecommunications environment you are faced with the challenge of minimizing the cost and complexity of equipment at the network edge. To meet this need the ADC Avidia Integrated Access Switch IAS combines the functionality of an ATM edge switch with a DSLAM. Then through subtending in which several systems are viewed and managed by a single management platform deployment of Avidia allows you to lower equipment and network management costs. Avidia concentrates multiple traffic streams to a single network uplink enabling the elimination of expensive ATM edge switches. By reducing the number of network elements you can reduce the number of element management systems eliminating associated overhead costs such as training and staffing. Through subtending you can lower the cost of delivering high-speed services to remote customers. This white paper explores subtending in more detail by discussing two different configuration types daisy-chain and star exploring both Central Office CO and remote cabinet deployment showing the economic benefits that deployment of the ADC Avidia platform provides. Subtending Overview Avidia subtending allows multiple systems to be viewed and managed as if they were one system through either a star or daisy-chain configuration. In either implementation multiple systems connect to one system that aggregates the transmission of all the attached systems and provides one network uplink. The aggregating system is known as the subtending or source system and each of the systems connected to it are known as the subtended or destination systems. The figure below illustrates example star and daisy chain systems and are just a few of the many configurations available through subtending. The subtending systems in each configuration aggregate the transmissions of the subtended systems and provide a network uplink through OC3
