Patent ID: 6944587

Claim:
An Ethernet adapting apparatus for data transfer between a standard Ethernet data pump and an Ethernet medium access controller via telecommunication medium, comprising: (a) a dual mode media independent interface which emulates in a PHY-mode the standard Ethernet medium access controller and which emulates in a MAC-mode the Ethernet medium access controller; (b) a switching device for setting the dual mode media independent interface in the PHY-mode or in the MAC-mode; (c) a data buffer for storing at least one Ethernet data package to be transferred between the standard Ethernet data pump and the Ethernet medium access controller; and (d) a 10BASES® data modem connected to the telecommunication medium, wherein the 10BASES® data modem reframes the data stored in the data buffer to 10BASES® data frames sent via the telecommunication medium; and wherein the dual mode media independent interface comprises a serial management interface connectable via a SMI-data line to an Ethernet medium access controller or a standard Ethernet data pump for the exchange of SMI-data frames including SMI-messages, and a data flow interface connectable via a data bus to an Ethernet medium access controller or a standard Ethernet data pump for the exchange of Ethernet data packages.
