2. DESCRIPTION
The SHDSL LTU receives a G.703 signal from the

customer. The G.703 and SHDSL signals are trans-
mitted/received via the chassis backplane connectors.
The SHDSL LTU supports loop rates from 192 kbps to

2.048 Mbps. The unit is 100 percent compliant with the
ITU recommendation (G.991.2) for SHDSL trans-
mission, ensuring spectral compatibility and interopera-
bility.
The Total Access 3000/3010 shelf must contain the
