The HiGain System provides a cost-effective, easy-to-deploy method for delivering G.703 High Capacity Digital
Service (HCDS) over metallic pairs. Customers can deploy fiber-like quality service over two unconditioned,
non-loaded copper pairs without using conventional span repeaters or cable pair conditioning and without the need
to separate pairs or remove bridged taps.
G.703 Plug-in Connections
The ADC HCP-322 Connector Panel, List 1 and List 2 (
), can be used to connect up to 22 G.703
circuits to HiGain ELU-319 line units housed in the HMS-318 shelf. The ADC HCP-322 List 1 panel has 44 BNC
connectors for connecting G.703 75
W
circuits to ELU-319 List 1, List 5 and 5D line units. The ADC HCP-322
List 2 panel contains 22 DB-15 connectors for connecting G.703 120
W
circuits to ELU-319 List 6 and 6D line
units. The ADC HCP-322 List 2 panel also includes wire-wrap pins for optionally connecting the connector case
of each receive (RCV) pair to frame ground. A typical application of the HCP-322 Connector Panel is shown in
Figure 8.
