There are no manual option settings on the HRE.
HRE operating power is derived from an HTU-C,
independent of line impedance or wire gauge. The
operating power from the HTU-C is also used to
span power the Low Voltage HTU-R.
The HRE operates at line losses up to 35 dB at 196
kHz, in both directions from the extender and
regenerates the 2B1Q signals to meet the
transmitted power spectrum of Bellcore
TA-NWT-0001210.
