Horizon Compact Release 1.01.00 Wireless Ethernet Product User Manual – Volume 2
3.4 Pause Frames
Pause frames are generated by the weaker (slower) link when its forward pipe gets full. Pause frames
inform the upstream device to “pause and stop sending traffic for a period of 5 msec”. When the Pause
Frame feature is enabled, Horizon Compact generates pause frames to the Ethernet switch when the
Horizon Compact receiving buffer hits the internally set threshold. The receiving buffer threshold is close
to 100 msec at GigE rate. At data rates lower than GigE, the data buffer will accommodate a lesser
amount of data. The Pause Frame feature can be used when CoS/QoS is enabled or disabled.
