The transmission mode of the Ethernet interface is defined here. On phones with a configurable switch the PC and the LAN port can be configured.

Configuration

The auto transmission mode is pre-selected:

auto: Automatic selection of the transmission speed.
10m-hdx: Corresponds to 10 MBit Half Duplex.
10m-fdx: Corresponds to 10 MBit Full Duplex.
100m-hdx: Corresponds to 100 MBit Half Duplex.
100m-fdx: Corresponds to 100 MBit Full Duplex.


Status

In addition, the status of the interface (Up or Down) and the Autonegation used (for example, 100m-fdx) are displayed.

Ethernet MDX

IP400, IP21 and IP3000 the ethernet interface has a switch to configure the port to be connected to a hub/switch or terminal.

On gateways with 2 ethernet interfaces ETH0 can be connected directly to a switch port, ETH1 can be connected directly to terminal. Other connections are possible if auto-MDX is supported in the switch or in the gateway or if a crossover cable is used.

Ipphones have a ethernet switch, form the firmware this is seen as a single ethernet interface. Again, the first interface can be connected directly to a switch, the second directly to a terminal ( e.g. a PC ).

IP800 (hardwarebuild below 108) and IP6000 (hardwarebuild below 200) and IP21 support Auto-MDX. Ipphones generaly do not support Auto-MDX, only the ipphones with gigabit ethernet support Auto-MDX.
