response time of the Aastra 800 communications system is not impaired by other
programs or server processes running simultaneously. Usually, the keyboard and
monitor hooked up to the server computer are protected against unauthorized
access and are only available for administrative purposes.

monitor hooked up to the server computer are protected against unauthorized
access and are only available for administrative purposes.
Furthermore, standard PC systems are possibly more likely to be optimized for
more obvious features while information on system failure dependability and pos-
sible length of operation are not provided. There are system components available
for purchase specialized towards increasing reliability of server operation. Using
such system components is recommended.

3.2.2 Capacity Characteristics
The Aastra 800 communications system is based on system software that has been
used reliably for years for hardware-based communications systems (PABX). These
specialized devices generally provide less CPU capacity, less RAM memory and less
hard-drive space than standard up-to-date PCs available in stores. However,
standard store PC systems do not have specialized hardware components which
have to be taken over by the PC's CPU for certain communication applications. The
CPU will thus have to offer sufficient performance capacity.

One example: With the normal VoIP system telephony, the system terminals com-
municate with each other directly. The Aastra 800 communications system is only
involved in switching the connection. This does not require much CPU capacity.
For a conference call, the voice data of all conference users have to be processed
by the CPU. This requires a substantially higher amount of CPU capacity.
