The DSLPipe DSU (SDSL) is a modem that allows you to send data across two dissimilar devices. The unit converts data to an SDSL format and sends it to the destination device.You can use the unit for high-speed symmetrical data transmission (from 144 Kbps to 2320 Kbps) on a single copper twisted-pair wire.

Note: You cannot use a DSLPipe DSU for channelized services such as voice transmission.

The DSLPipe DSU uses 2B1Q line encoding with echo cancellation to transfer at a high data rate. It also provides high immunity to background noise. The size of the wire, in part, determines the maximum transmission rate and distance, as shown in Table 1-1.
