(1) Multi-Channel Configuration Installation Wiring Notes

This section provides detailed information on the external interface and system 
connections involved in the installation of an HSD-128 and HSD-X transceivers for 
Multi-Channel configuration operation.

Table 3–33, Table 3–34, Table 3–35, and Figure 3–38 illustrate the interconnection 
and contact assignment details of a Multi-Channel HSD configuration. 

This section provides detailed information on cable loss considerations, the splitter 
for the receive path, and the combiner for the transmit path.
