Revision History

This is the second issue of this practice. Revisions to 
firmware are represented on the menu tree.

2. DESCRIPTION

The SHDSL LTU receives a G.703 signal from the 
network and transmits an SHDSL signal to 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

Figure 1.  Total Access 2W/4W SHDSL LTU

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 
Enhanced System Controller Unit (SCU), in order to 
access the SHDSL LTU menus. For more information 
regarding the SCU (P/N 1181018L1), refer to the Instal-
lation and Maintenance Practice (P/N 61181018L1-5).
