Abstract
An UTOPIA level 2 interface over a backplane for connecting up to 31 Physical layer devices to one ATM layer device in a logically partitioned manner utilizing full bandwidth. The communications data is received on a first terminal at a first transfer rate. The communications data transfer rate is reduced from the first transfer rate to a second transfer rate. At the second transfer rate, the communications data is transferred over a backplane to a second terminal. On the second terminal, communications data transfer rate is increased from the second transfer rate to the first transfer rate. The first transfer rate is greater than the second transfer rate.
