GENERAL
The HDSL2 repeater (H2RX), as shown in
Figure 1
and
of HDSL2 transmission beyond the Carrier Serving Area (CSA) distances. The Version B
H2LXC and Version B H2LXR modules provide a maximum reach of 12,000 feet over 24
gauge wire or 9,000 feet over 26 gauge wire, without a repeater (which meets the CSA
requirement). When an H2RX is placed mid-span between a Version B or later H2LXC and a
Version B or later H2LXR, the maximum reach can be doubled to 24,000 feet over 24 AWG
wire; or 18,000 feet over 26 AWG wire.
