Figure 1-2. Example: Using a DSLPipe DSU as COE

The DSLPipe DSU in Figure 1-2 accepts HDLC data from V.35 Router A. The unit converts the data into SDSL format and sends it, via a WAN link, to another DSLPipe DSU that is configured as CPE. That unit then sends the data to V.35 Router B.

Figure 1-3. DSLPipe DSU architecture

The DSLPipe DSU driver picks up the HDLC data and sends it to the Ethernet

controller for processing. The data is sent via the bus to the SDSL chip. The chip

converts the data to RFC 1490 packets and sends it across a WAN link to another

device.
