Abstract: Methods for testing multiple data packet signal transceiver devices under test (DUTs) with a shared tester. The DUTs transmit their data packet signals until predetermined numbers of data packets have been transmitted or predetermined time intervals expire, following which, each DUT awaits a synchronization request to begin transmitting data packets to the tester. Alternatively, the tester determines when its receiver is available for receiving data packets, following which, synchronization requests are sent to respective DUTs to initiate their transmissions of data packets to the tester. Further alternatively, power levels among data packets initially transmitted from the DUTs are monitored to determine when they are indicative of them having settled. As each DUT data packet signal power settles, a status signal indicating the settled nature of each DUT is provided to the tester which then begins receiving the respective DUT data packet signals, as they settle in power, for analysis.

The port switch SWP2 may receive frames from the user switch SWU1, and when the frames are to be originally transferred from a port P1 to the fabric switch SWF1, the frames are transferred though the redundancy port Pr to the port switch SWP1 if there is a fault on the port P1 side. The port switch SWP1 transfers the frames received from the port switch SWP2 through the redundancy port Pr to the fabric switch SWF1 that is the original transfer destination.

Abstract: In the subject system for polarity detection, link initialization between a primary device and a secondary device may be performed in at least two stages, a half-duplex stage when only the primary device transmits initialization signals and any encoded handshaking signals may be set to false, and a full-duplex stage when both devices may transmit initialization signals. The secondary device may perform polarity detection during the half-duplex stage. If the secondary device determines that the polarities of the received signals are reversed, the secondary device may reverse the polarities of any signals subsequently received from, and transmitted to, the primary device. In this manner, the polarities can be corrected for both devices during the half-duplex stage by the secondary device. The secondary device may initiate the full-duplex link initialization stage, during which any handshaking signals may be exchanged, by transmitting signals to the primary device.
