Reference:Configuration/ETH/Link
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.
