Abstract:
1. A method for selectively sending data upstream comprising: detecting whether a response from a local device is available to be sent upstream; detecting whether a downstream device is providing a data packet be sent upstream; detecting whether data from a local storage unit is available to be sent upstream; coupling, via a bypass multiplexer, a transmission port to the local device when the response from the local device is available to be sent upstream; coupling the local storage unit to the downstream device to temporarily store the data packet provided by the downstream device while the transmission port is coupled to the local device, wherein a length of the data packet depends on a type of data being transferred; coupling, via the bypass multiplexer, the transmission port to the local storage unit while the temporarily stored data packet in the local storage unit is sent upstream; and coupling, via the bypass multiplexer, the transmission port to the downstream device after the temporarily stored data packet in the local storage unit is sent upstream.
