MECHANISM TO SUPPORT A UTOPIA INTERFACE OVER A BACKPLANE

摘要

A UTOPIA level interface over a backplane for connecting up to 31 Physicallayer devices (250, 270, and 290) to one ATM layer device (210) in a logicallypartitioned manner utilizing full bandwidth. The communications data isreceived on a first terminal at a first transfer rate. The communications datatransfer rate is reduced from the first transfer rate to a second transferrate. At the second transfer rate, the communications data is transferred overa backplane to a second terminal. On the second terminal, communications datatransfer rate is increased from the second transfer rate to the first transferrate. The first transfer rate is greater than the second transfer rate.
