5.2.4
Some considerations about the performance are made by investigating the maximum
data rate. Further investigations are made about the bus occupancy by all busmasters
and the MUNICH32 poll access’ influence on the data rate. Finally the processing of one
frame is illustrated.
Data Rates
The data rate during transmission from the ISDN into the Ethernet was tested.
Figure 95
Data Rate
The size of one data buffer is 128 Byte. If the number of channels exceeds 24 the data
rate depends on the MUNICH32 transmitter. If the transmitter is initialized the data rate
decreases. This shows the influence of the MUNICH32 polling the Hold bit.
