G. MAINTENANCE AND TROUBLE SHOOTING
The BTS-7010 Multi-Channel Booster is a digital broadband booster designed to operate with a maximum
of four simultaneous input signals. The BTS-7010 is capable of operating as a wireless video/data
transmitter at a nominal power level of 5.0 watts (total average). The unit is comprised of a 64 QAM
modulator (Vyyo V300 Wireless Modem Termination System), frequency agile QAM upconverter
(Wavecom MA4040D) and BTS-7010 Multi-Channel Booster. The WMTS receives full duplex Ethernet
data frames (100BaseT), multiplexes the signal in TDM and modulates the signal to a 64 QAM, 44 MHz
IF carrier. The IF output from the QAM modulator is upconverted to the superband (222 to 408 MHz)
frequency of the desired channel by the QAM upconverter then directed to the input to the multi-channel
booster where it is upconverted and amplified to the MMDS/ITFS frequency range (2500.00 MHz to
2690.00 MHz). The unit is utilizes ALC circuitry to automatically maintain output power and is designed
to operate in a system with other identical booster units in an N+1 redundant configuration.
This manual covers the description, installation, set-up, operation, schematic and interconnect drawings, as
well as other useful technical information.
TECHNICAL MANUAL DESCRIPTION
This manual has been provided to assist with the set-up, operation, and maintenance of the transmitter.
This manual also offers a brief system description, block diagrams, interconnect, front panel description,
rear panel description, and a specification sheet. If after reviewing this manual, you still have questions,
please contact the ADC Service Company at (724) 941-1500. A Customer Service Technician will be glad
to assist you.

ADC certifies that upon leaving our facility, your equipment was undamaged and in proper working order.
Please inspect all material upon arrival for any sign of damage. The shipping container should be examined
for obvious damage indicative of rough handling. Remove the sled modules and all other material from the
shipping container and check for damage: dents, large scratches, or broken connectors etc. Open the
translator and remove all packing material from inside the unit and inspect for damage. Any claims against
in-transit damage should be directed to the Carrier.
SITE CONSIDERATIONS
The BTS-7010 is provided with an environmentally controlled cabinet and therefore may be operated both
indoor and outdoor. It is very important to verify that adequate AC power is available to the system.
Complete the following for equipment installation:
The unit is supplied with a cabinet, carefully remove the cabinet from the shipping container. If the
individual sleds and chassis has been shipped separately, the internal shipping material must be removed
from inside the cabinet before the tray is installed. Cut and remove the cable ties or cords which hold the
tray harness breakouts to the tray slides. Carefully remove the foam packing material from around the
cables, and connectors. Do not use a knife or other sharp object, as these may cut into the harness wires.
Once the cabinet has been properly positioned, the trays can now be installed.
If each of the chassis do not align evenly, loosen the hardware holding the chassis in place. Move the tray
accordingly and tighten the hardware again. Repeat if necessary until the all chassis are aligned evenly.
SYSTEM CHECK OUT AND OPERATION PROCEDURE
ELECTRICAL INTERFACE PROCEDURE
With the unit properly installed and adjusted in the equipment rack, the process of electrically interfacing
the transmitter can begin. The following steps should be completed:
INSTALL AC LINE CORD.
A line cord is provided with each BTS-7010 Unit .. Insert the female connector of the line cord into the
tray's AC input connector (J220). Make certain that the rear panel power switch is in the "OFF" position,
then plug the line cord into an appropriate AC outlet to power the unit.
An alternate hard wire input is provided at jack J221. This alternate AC input may be used to connect
directly to the system AC.
NOTE:The BTS-7010was designed for 220 VAC 50/60 Hz. operation.
CAUTION:Never remove the RF output coaxial
cables or otherwise unload the RF
outputs while operating. This may
cause harmful exposure to RF
radiation.
CONNECT RF OUTPUTS AND RF INPUTS:
Connect the output coaxial cables from the Bandpass Filter RF Outputs (J201-J204) to the transmit
antenna. Connect the UHF (222 to 408 MHz) output of the UHF tunners to the IF input of the BTS 1.0
(JJ231 – J234).
Connect the GPS antenna feed to the GPS Antenna input (J250). Connect 10 MHz input (J251) to 10
MHz reference if used.
INITIAL TURN ON PROCEDURE
Before beginning routine operation, the unit should be given a step-by-step check of its functions to verify
proper interface and operation. This will give the operator a chance to become familiar with the unit. The
following procedure should be followed for the initial turn-on of the unit:
1.APPLY AC POWER TO BTS-7010 UNIT.
Move the translator rear panel AC switch to the ON position. The Power Failure
Warning and Switching Supply LEDs on the front panel of the Power Supply
sleds will illuminate green. This indicates that the power supply is functioning
normaly. If this is not the case, you should then refer to the troubleshooting
section of this manual.
2.OPERATE UNIT
After System starts, observe LCD display on front panel of System monitoring
sled. Select the appropriate transmitter sector (1 thru 4) by pressing the uparrow. After selecting the desired sector, press the Operate (OPR) button. This
should cause the transmitter to go into the Operate mode. (if not, refer to
troubleshooting section).
3.MONITOR FORWARD OUTPUT POWER.
Now that the control and DC functions of the translator have been established as
operative, observe the Forward power meter readings on the LCD display for the
transmitter sector selected and check that the reading is approximately 100%.
4.MONITOR REFLECTED POWER.
Observe the Reflected power meter readings on the LCD display for the
transmitter sector selected and check that the reading is below 5% ..
5.RECORD LEVELS ON LOG SHEET
Once the transmitter is operating at full power, record all metered levels of the
transmitter on a dated and initialed sheet. This sheet can be used for future
comparison of the unit's operation. Comparing this information to the factory test
data is always a good practice.
