Abstract: A branch exchange comprises at least one interface module coupled to a plurality of telecommunication connections including a first telecommunication connection and a second telecommunication connection. A converter is coupled to the at least one interface module and a network interface controller (NIC). The converter is configured to communicate at least one time division multiplexed (TDM) data stream between the converter and the at least one interface module. The converter is further configured to packetize data from one of the telecommunication connections into a first plurality of data packets transmitted to the NIC by the converter. A branch exchange manager is configured to receive the data from the NIC and cause the data to be transmitted over the second telecommunication connection.

Abstract: An exercise apparatus has an auxiliary weight system which can be used with virtually any exercise machine irrespective of its stroke length and which is relatively free of resistance due to friction caused by the interaction of the weights and their guide rods.
