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.

BT100 options and accessories

Model	Description	Function
ADU-*	Automatic Drive Unit	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.
QADU*	QAM Automatic Drive Unit	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.
TDU	Thermal Drive Unit	This board controls amplifier output levels that change with
		cable attenuation for the sensed temperature.
SFE-100-*	STARLINE Forward	This 1GHz equalizer compensates for cable properties in 1 dB
	Equalizer	increments from 0 dB through 22 dB. You must install the
		appropriate value.
SRE-*-*	STARLINE Return	This bandwidth specific equalizer compensates for cable
	Equalizer	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.
SCS-*	STARLINE Cable Simulator	This simulator compensates for cable properties. You must
		install the appropriate value.
JXP-*B	Fixed attenuator	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.
JXP-TH*C	Thermal attenuators	This option compensates for gain changes with temperature in
		the return path.
FTEC-230-R	Fast Transfer Electronic	This surge arrestor is used for overvoltage protection.
	Crowbar
ICS-II	Ingress Control Switch	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.
