See Figure 4 - 16. Checking the box next to
function willing to stop receiving traffic. When the radio input buffers approach overflow,
the function sends a pause message to the ink partner that is transmitting data to the
radio, telling the device to temporarily stop sending data. The link partner will stop send-
ing data if the device has and is provisioned with the Allow Option Pause function.
If the link partner is either not equipped with or is not provisioned for input pause, data
overflowing the registers in the radio will be lost, regardless of the provisioning for input
pause in the radio. Any time there is an overflow, the radio will alarm and indicate
Dropped Frames on the Performance Monitor screens.
