* If client-server applications handling a huge number of packets per second are used (> 1000pps:
CAD type application/specific database access), it is not advisable to connect the workstation to the
6731i PC port: use instead a direct connection from the workstation to the network switch or the PC
port of a 675xi/6735i/6737i/6739i/53xxip type model.
** Supports headset instead of handset
