Using network ports more efficiently
OpenStage 60/80 SIP has a built-in 10/100 Mbps Ethernet switch.
OpenStage 60 G/80 G SIP has a 1000 Mbps Ethernet switch. This means
that you can directly connect one additional network device in each case
(e.g. a PC) via the telephone with the LAN. The telephone-PC connection
option must first be activated on the telephone by administrator.
Using this connection option saves one network port for each switch used
and requires fewer or shorter network cables when arranged correctly.
