Paper Abstract

The Broadband Access Facility (BAF) is an affordable method of providing broadband services for the local loop. It is based on the transport of ATM Cells over a shared fiber passive optical network (PON) with a passive optical tree and branch topology. The PON supports 622 Mbits/s over 32 network terminations (BAF-NTs) using a passive optical splitter/combiner. The management architecture of the BAF is based on the CCITT Telecommunications Management Network (TMN) recommendations. The management and control requirements have been analyzed using the OSI decomposition into five functional areas: configuration management (controls the `ranging' procedure which compensates for different distances between the BAF-NTs and the BAF-LT); performance management (manages the allocation of bandwidth between the subscribers to provide statistical gain and monitors network parameters to measure how well the BAF MAC protocol provides the agreed service); fault management (set of functions which enables the detection, isolation, correction of abnormal operation); security management (supports encryption cells which is necessary due to their broadcasting to all the BAF-NTs); and finally, accounting functions.
