Abstract:
1. A circuit module comprising: a loop switch comprising: a port bypass circuit connected to the transmit port and the second receive port of the second retiming element; wherein the port bypass circuit is configured to receive a reconditioned data signal from the transmit port of the second retiming element and to transmit that reconditioned data signal to a second output port of the circuit module; wherein the port bypass circuit is further configured to receive a data signal from a second input port of the circuit module, recondition that data signal, and transmit the resulting reconditioned data signal to a third output port of the circuit module; wherein the port bypass circuit is further configured to receive a data signal from a third input port of the circuit module and transmit that data signal to the second receive port of the second retiming element of the loop switch; and wherein the second retiming element of the loop switch is configured to recondition the data signal transmitted to its second receive port.
