Description
Service level agreements guaranteeing quality of service have helped your organization to keep old customers and win new ones over. Although it may be easy for the sales department to ink a service level agreement, you have to handle the constant problems of phase fluctuations, jitter, and wander, that threaten the quality of service spelled out in these service level agreements. By showing you how to properly set up a network, test its performance, and troubleshoot any systems glitches, this book is an on-the-job companion that you can turn to time after time to ensure quality network service. This implementation, maintenance, and troubleshooting manual goes beyond overview books and standards guides to give you the technical insight and hands-on knowledge you need to know to deploy today's digital networks and keep them running 24/7. From the principles of digital technology and SDH, to network synchronization and ADSL qualification, this practical resource provides in-depth coverage of the most critical areas. Over 300 illustrations support key topics.
