• Manufacturer Part Number: AX88615
• Description: 5-Port 10/100BASE Ethernet Switch
• Manufacturer: ASIX [ASIX Electronics Corporation]

threshold, the MAC of port will send out a PAUSE frame with maximum delay. The switch will send out a PAUSE
frame with zero delay after below FlowControlActive threshold.
For the receiving channel, the switch will not transmit the next packet whenever received a PAUSE frame with non-zero
delay. The switch will resume packet transmission either after the pause timer expired or a PAUSE frames with zero
delay received.
In half-duplex mode, the switch will receive and transmit the packet in accordance to 802.3 CSMA/CD. If the occupancy
of the buffer memory is above the FlowControlActive threshold, the MAC of port will send out JAM pattern .
