Connecting a PC to an IP Telephone
You can connect a PC to some IP telephones using the IP telephone’s secondary
port. In this case, only a single port from the LAN’s network interface (switching hub) is required to connect
both the IP telephone and PC to the LAN.
Note
• Use an Ethernet straight cable with an RJ45 connector to connect a PC to the IP telephone. 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.
• Only a PC can be connected to the secondary port of an IP telephone. Other IP telephones
or network devices such as routers or switching hubs, cannot be connected.
• In cases where a PC is connected to the secondary port, if the IP telephone connection to the PBX is
disconnected or reset, LAN communication to the PC will also be disrupted.
