5. SBC Laboratories 5 1 Mar-04 ©SBC Laboratories, Inc., 2004 SBC’S Interest in BPON Only “future-proof architecture” – one network for all services –Voice –High–Speed Data –Video (HDTV, Video-on-Demand, etc.) Effective service life of fiber vs copper Falling technology costs –Cost-effective solution in new construction –Overbuild is still a challenge Increased reliability –No outside plant electronics Home builders demand fiber SBC competitors are providing full-service solutions

11. SBC Laboratories 11 1 Mar-04 ©SBC Laboratories, Inc., 2004 Required Properties of the EMS for SBC – Not just a gateway Fully functional management system, capable of managing the NEs within its jurisdiction. Not just a gateway. Greater reliability than any single NE. Highly available. Tightly synchronized with NE configuration data and NE state and status conditions. Reliable event channels high throughput and processing capabilities. Able to store at least one week’s worth of logged information including alarm log records, user task logs, performance statistics. Maintains relationship between Service Instance Id and supporting network resources. Supporting sub-network management and abstraction. Possessing GUI design optimizing user efficiency and minimizing training.

12. SBC Laboratories 12 1 Mar-04 ©SBC Laboratories, Inc., 2004 Initially specified by operator with future migration under control of operator. EMS presents services to the NMS, more sophisticated services than database manipulations. To the greatest extent possible, these interface objects should be “technology neutral”, so that the interface and system behavior of EMS and NMS doesn’t churn as new technologies are introduced. Adequate exception raising. Session Layer protocol mechanisms. Standards-based if appropriate standards exist. EMS Interfaces
