Résumé des résultats (Abstract) (Anglais)

Main Objectives of the BONAPARTE project
The main objective of the project is to demonstrate the reliability, flexibility and cost-effectiveness of APON systems by conducting the user trials involving the real users and applications. Through such user trials the project planned to prove that broadband ATM access is a viable way to introduce integrated broadband communication to small business and residential customers.
Technical approach
To achieve the set objectives the project was organised in 4 superworkpackages: trial site operation and interconnection (SWP1), Users and applications (SWP2), System enhancements and upgrades (SWP3), Experiments, user feedback and evaluation (SWP4).
Ascom's contribution
Ascom's main contributions were in SWP3 with supporting function in SWP1 for trials (SWP4).
The major contribution of Ascom was the development of a key building block for the upstream TDMA transmission subsystem (Time Division Multiple Access), the Bit & Slot Synchronizer (BSS). The BSS is very critical in terms of system reliability. The specification, design, and final realisation of this complex high speed ECL ASIC (Emitter Coupled Logic, Application Specific Integrated Circuit) has been achieved using the SH 100G Gate Array from Siemens. The input data signal with a data rate of 620 Mbit/s coming from the burst mode receiver is sampled with a rate of 5Gigasamples per second. Number of BSS modules were delivered to the consortium for the project use. The board level integration, test and performance measurements were done both in labs and test sites. It was necessary to build up a complete testbed in Ascom's laboratory in order to be able to test independently the whole TDMA subsystem including the BSS ASIC. BSS is now part of the enhanced system at present and will be used for developing next generation access system.
Ascom was the workpackage leader of VB5 specification, design and implementation. The major contribution from Ascom was the definition of open interface VB5 for facilitating the deployment of mulitvendor system in the access area. Ascom implemented the SAAL part of VB5, which is one of the major task in the implementation activity. The work was contributed to standards and the contributions are now part of internationally agreed standards. Thanks to close collaboration of EXPERT project the project could demonstrate theVB5 interface operating across access node and service node. Only access part was developed in BONAPARTE. The enhanced BONAPARTE system was demonstrated from TURIN testbed, involving multiple users from the hospitals and university. BONAPARTE is the first project to implement such an interface and pave a way for full service access network (FSAN) that has been initiated by industrial fora. The results were contributed to the VB5 guidelines of the NI chain group.
