Ethernet Cable
WAN port is used for composing VoIP network. VOSS12 WAN port provides
Auto-MDIX(Medium-Dependent Interface Crossover) so can apply direct and
cross cable, and can use 10BaseT, 100BaseTX connection. For 10BaseT
connection, use Category-3 cable, and for 100BaseTX connection, use Category-5
cable.
One end of Ethernet cable should be connected to VOSS12 WAN port and the
other end should be connected to Hub or Switch. However, sometimes IP
duplication can be happened in internal network, so connect one end to VOSS12
then refer to the web management chapter for the other end connection.
If the connection doesn’t support 100M connection, please check Hub or Switch
capacity.

with PSTN telephone line which is connected to PBX or a Key Telephone System.
One end of cable is connected to FXO port on VOSS12 and the other end is
connected to PBX, Key Telephone System(KTS) or Wall Jack.
