The network parameters must be set for the IP telephone before it can be used.Connecting an IP Telephone to a Switching HubWhen connecting an IP telephone to the LAN, connect it to a switching hub.Note• Use an Ethernet straight cable with an RJ45 connector to connect the IP telephone to a switchinghub. The cable should be a CAT 5 (Category 5) or higher for 10BASE-T/100BASE-TX, or CAT 5e(Enhanced Category 5) or higher for 1000BASE-T.• When using the VLAN feature on the network, make sure that the switching hub to be connected isIEEE 802.1Q compliant and is configured for VLANs. In addition, the port of a switching hub that theIP telephone is connected to must be set to "Trunk" port, to allow VLAN tagging. Consult your net-work administrator for details.• Since an IP softphone is installed and operates on a PC, the PC must be connected to the LAN touse the IP softphone on the network.The diagram below is for connecting an P-SIP to a switching hub.
