Ethernet to ADSL adapter
First Claim
1. An Ethernet to ADSL adapter for controlling data communication between an Ethernet port and an ADSL modem connected to an ADSL channel, comprising:
- a first buffer for storing data packets received at the Ethernet port;
means for transmitting said data packets from said first buffer to the ADSL modem at a first ADSL transmission rate;
means for transmitting a jamming signal from the Ethernet port when said first buffer contains a first predetermined number of data packets and data packets are not available for transmission to the Ethernet port, wherein transmission of additional data packets to the Ethernet port by other Ethernet nodes is inhibited by said jamming signal; and
means for transmitting data packets received from the ADSL modem to the Ethernet port at a second ADSL transmission rate.

Abstract
An Ethernet ADSL adapter controls data communication between an Ethernet port and an ADSL modem connected to an ADSL channel. The adapter includes a first buffer for storing data packets received at the Ethernet port, a second buffer for storing data packets received from the ADSL modem and a controller. When the first buffer contains a first predetermined number of data packets and data packets are not available for transmission to the Ethernet port, a jamming signal is transmitted from the Ethernet port. The jamming signal inhibits transmission of additional data packets to the Ethernet port by other Ethernet nodes until space is available in the first buffer. When the second buffer contains a second predetermined number of data packets, a pause signal is transmitted to the ADSL modem. The pause signal inhibits further transmission of data packets to the ADSL modem on the ADSL channel until space is available in the second+buffer. When a pause signal is received from the ADSL modem, transmission of data packets to the ADSL modem is inhibited.
