Flash Download advisements
• Since the Flash Downloading feature of the M3900 takes some
bandwidth from the system signaling path while it is operating, it is
recommended that downloading be scheduled in off-peak hours for best
results. There is some real time impact to the system since the system
processor is busy doing the downloads. However, there is no impact to
call processing, since call processing has a higher priority. Therefore,
downloads take longer during peak traffic times because the system
processor is busy doing call processing and cannot devote as much time
to the M3900 downloads. There is no difference between large and small
systems for this.
