Although [HDSL] is attractive for replacing existing T1 lines, it is not suitable for residential subscribers because it requires two twisted pair, whereas the typical residential subscriber has a single twisted pair. [SDSL] was developed to provide the same type of service as [HDSL] by over a single twisted-pair line. As with [HDSL], 2B1Q encoding is used. Echo cancellation isused to acheive full-duplex transmission over a single pair. |
