IP Office IP Phones: Potential VoIP Problems

1.12 User PC Connection

To simplify the number of LAN connections from the user's desk, it is possible to route their PC Ethernet LAN cable via some H323 IP phones. The LAN cable should be connected from the PC to the socket with a PC symbol () at the back of the IP phone. This port supports 10/100Mbps ethernet connections. The PC's network configuration does not need to be altered from that which it previously used for direct connection to the LAN.

Those phones that include a PC pass-through port and also provide priority to phone voice traffic over PC data traffic are normally indicated by an SW suffix in the phone name. However some phones have a PC pass-through port but do not provide switching priority.

The table below summarizes the phones:

*The 4606, 4612 and 4624 phones can be upgraded to provide voice priority switching by fitting an Avaya 30A Switch Upgrade Base to the phone. In addition, this base also allows the phone to be powered from a IEEE 802.3af Power over Ethernet source.

Gigabit Ethernet

If a 1000mbps ethernet connection is being used then a separate Gigabit Adapter (SAP 700416985) must be used. This device splits the data and voice traffic before it reaches the phone, providing a 10/100Mbps output for the phone and a 10/100/1000Bbps output for the PC. The adapter is powered from the phone's existing PoE supply or 1151 type power supply unit. Refer to the "Gigabit Ethernet Adapter Installation and Safety Instructions" (16- 601543).
