Abstract: An apparatus is provided which comprises: an input/output (I/O) port; a first circuitry to update an in-band presence detect field, based on communication via an in-band channel; a second circuitry to update an out-of-band presence detect field, based on communication via an out-of-band channel; and a third circuitry to update a presence detect state change field, wherein the third circuitry is to selectively ignore the out-of-band presence detect field and utilize the in-band presence detect field, while the third circuitry is to update the presence detect state change field.

Abstract: An enhanced general input/output communication architecture, protocol and related methods are presented.

Abstract: A method includes providing a device under test (DUT) which has an input port and an output port. The DUT also has a squelch detector which is coupled to receive a signal from the input port. The DUT also has a receiver amplifier coupled to receive a signal from the input port. In addition, the DUT also has a transmitter to transmit data signals from the output port. The method further includes providing a loopback connection from the output port to the differential input port. The method also includes controlling the transmitter to transmit a test signal from the output port to the input port. The method includes monitoring at least one of respective outputs of the receiver amplifier and the squelch detector to determine whether a leakage condition exists in the DUT. Other embodiments are described and claimed.

Abstract: A system and method are described for detecting packet loss using an error checking signature, such as a cyclical redundancy check (CRC), while transmitting packets between a sender and a receiver. A counter is present on both the sender and the receiver, the two counters initially synchronized with each other. The CRC is generated using a sequence number provided by the counter at the sender. As the packets are sent, the sender counter is incremented. The receiver uses a sequence number from the receiver counter to decode the CRC. If all the packets are received, the sequence number to decode should match the sequence number to encode. Therefore, if the CRC does not decode properly, a packet has been lost or corrupted. A message to resend the packets is sent to the sender. The receiver counter is not incremented until the proper packet is received and decoded.
