Maximum station delay
The maximum station delay (max. TSDR) specifies the longest interval required by
a node in the subnet between receiving the last bit of an unacknowledged frame
and sending the first bit of the next frame. After sending an unacknowledged
frame, a sender must wait for the max. TSDR to elapse before sending a further
frame.
Minimum station delay
The minimum station delay (min. TSDR) specifies the minimum time that the
receiver of a frame must wait before sending the acknowledgment or sending a
new frame. The min. TSDR takes into account the longest interval required by a
station in the subnet for receiving an acknowledgment after sending a frame.
