Item Functionality

Meets Reqs?

Requested training pattern is embedded in a packet or used to terminate a packet

1A. ACTION: Moves from the port OK state to the input error-stopped state

1B. ACTION: Sends a packet-not-accepted control symbol to the sending device

1C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

1D: ACTION: Moves from the input error-stopped state to the port OK state

Device encounters S-bit parity failure

2A. ACTION: Moves from the port OK state to the input error-stopped state

2B. ACTION: Sends a packet-not-accepted control symbol to the sending device

2C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

2D: ACTION: Moves from the input error-stopped state to the port OK state

Device encounters incorrect CRC for a packet

3A. ACTION: Moves from the port OK state to the input error-stopped state

3B. ACTION: Sends a packet-not-accepted control symbol to the sending device

3C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

3D: ACTION: Moves from the input error-stopped state to the port OK state

Device encounters unexpected ackID value in a packet

4A. ACTION: Moves from the port OK state to the input error-stopped state

4B. ACTION: Sends a packet-not-accepted control symbol to the sending device

4C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

4D: ACTION: Moves from the input error-stopped state to the port OK state

Device encounters a packet that exceeds the 256 byte maximum packet size limit

5A. ACTION: Moves from the port OK state to the input error-stopped state

5B. ACTION: Sends a packet-not-accepted control symbol to the sending device

5C. ACTION: Device silently discards all packets until a restart-from-error (link-request/input-status)

control symbol is encountered

5D: ACTION: Moves from the input error-stopped state to the port OK state
