Options and Accessories
The factory ships the BT100 as a fully functional unit, but you must configure it appropriately
for the field location requirements. You must install the correct forward equalizer or broadband
cable simulator and input pad to place the unit into service. Section 3, "Amplifier Setup"
provides information to assist you in this task. Use model JXP-*B pads to control field signal
levels. To compensate for temperature, install the ADU, QADU, or TDU before placing the
BT100 into service. You can install other items such as return thermal attenuators or ICSs at
your discretion, but these do not render the BT100 inoperative if they are not included.
Table 2-1 provides a comprehensive list of options and accessories for the BT100 amplifier. See
Section 3, "Amplifier Setup," or the Motorola online product catalog for additional information.

Function
By monitoring changes in level of the selected pilot carrier, this
board automatically controls amplifier output levels that
change with cable attenuation and hybrid output for the sensed
temperature.
This board automatically controls amplifier output levels that
change with cable attenuation and hybrid output. The selection
of a pilot frequency (QAM modulated digital channel) is
required.
This board controls amplifier output levels that change with
cable attenuation for the sensed temperature.
This 1GHz equalizer compensates for cable properties in 1 dB
increments from 0 dB through 22 dB. You must install the
appropriate value.
This bandwidth specific equalizer compensates for cable
attenuation in 1 dB increments from 0 dB to 12 dB for S-split (2
dB increments for all other splits). You must install the
appropriate value.
This simulator compensates for cable properties. You must
install the appropriate value.
This pad is used to attenuate excessive input signal and can
be used to adjust amplifier gain. It is available in 1 dB
increments from 0 dB to 26 dB. You must install the
appropriate value.
This option compensates for gain changes with temperature in
the return path.
This surge arrestor is used for overvoltage protection.
This option enables remote monitoring, isolation, and reduction
of ingress on the return path by providing signal attenuation of
6 dB or cutoff of 38 dB typical. The unit is shipped with
jumpers in these locations. The ICS can be ordered separately
and customer installed. To control the ICS, you must install the
LIFELINE status monitor available from AM Networks.
