LIFELINE status-monitoring system, you can attenuate the return path through the line
extender by 6 dB or by 38 dB. By reducing the ingress level at the headend or monitoring point,
you can further isolate the ingress source. After an ingress source is isolated to the last possible
amplifier, node, or line extender, you can shut the return path off at that location. This limits
the impact of the ingress on the remainder of the network while eliminating the source of
ingress.

The factory ships the amplifier as a fully functional unit, but you must configure it
appropriately for the field-location requirements. You must install the correct equalizer or
broadband cable simulator to place the unit into service. Section 3, "Amplifier Setup" provides
information to help you select the correct equalizer or broadband simulator. Use model JXP-*T
pads to control field signal levels. To compensate for temperature, install the automatic drive
unit (ADU) or thermal drive unit (TDU) before placing the unit in service. You can install other
items, such as a return amplifier and additional surge protection at your discretion, but these
options do not render the unit inoperative if they are not included.
Table 2-1 provides a comprehensive list of options and accessories for the BLE*/* and Figure 2-9
illustrates their locations.

This board automatically controls amplifier output levels that
change with cable attenuation and hybrid output. The selection of
a pilot frequency is required.
This board controls amplifier gain and slope for changes in cable
attenuation for the sensed temperature.
This kit enables two-way operation and includes a high-or low-gain
return hybrid and jumpers.
These equalizers are not bandwidth restricted and compensate for
0 dB and 1 dB of cable, respectively, from 5 MHz to 1 GHz.
This bandwidth specific (750 or 870 MHz) equalizer compensates
for cable properties in 1 dB increments from 2 dB through 22 dB.
The appropriate value must be installed. See the product catalog
for additional information.
This equalizer compensates for cable attenuation in 1 dB
increments from 0 dB through 12 dB for S-split (2 dB increments
for all other splits). The appropriate value must be installed. See
the product catalog for additional information.
This simulator compensates for cable properties. The appropriate
value must be installed. See the product catalog for additional
information.
This pad attenuates excessive input signal. It is available in 0.5 dB
increments from 0 dB through 26 dB. The appropriate value must
be installed.
This option compensates for gain changes with temperature in the
return path.
