Full-Duplex (10Mbps or 100Mbps)
Full-duplex data transmission means that data can be transmitted in both
directions on a signal carrier at the same time. For example, on a LAN with a
technology that has full-duplex transmission, one device can be sending data on
the line while another device is receiving data. Full-duplex transmission implies a
bidirectional line (one that can move data in both directions). On the IP phones,
you can set the full-duplex transmission to transmit in 10Mbps or in 100Mbps.
Configuring Ethernet Ports 0 and 1
You can configure the Ethernet port transmission method to use on the IP phones
using the configuration files, the IP Phone UI, or the Aastra Web UI.
