VERSION 1.55 iMPLEMENTA TION MANUAL Document No. 3337147
1.2.1.1 Headend Control Unit (HECU)
The HECU is only used in the HEE primary rack conﬁguration. The major HECU
hardware components are:
- Computer, Rack Mountable Pentium 100 MHz
- Monitor, Rack Mountable
- Keyboard, Rack Mount
0 Mouse, PS/2
0 Computer Power Cord
- Monitor Power Cord
The HECU monitors and controls the CMI and HIC units. It monitors various system
parameters to verify that the units are operational and that the power levels are at the
proper level. The HECU is the primary control/monitoring system that handshakes with
the other units.
The HECU communicates with the HICs over an RS-485 interface via a Lonworks® card
located in the computer.
The major software HECU components are:
- Microsoft® DOS Version 6.22
o Microsoﬁ® Windows?“ Version 3.11
- Software Drivers for custom HECU functions
1.2. 1.2 15 MHz Distribution Assembly
The 15 MHZ Distribution Assembly is used in both rack conﬁgurations. The assembly
requires +Z4V and 15-MHz input for operation. The distribution assembly accepts a single
15AMHz input from the Base Transceiver Station (BTS) and provides 16 reference outputs
for distribution to the BIOS. Signal ampliﬁcation for each 15-MHz output is approximately
unity gain (0 dB). Unused ports are terminated with 50 ohms. Each installed HIC uses the
15-MHz reference signal.
1 .2. 1.3 Headend Interface Convener (HIC)
The HIC is the direct interface to the Base Transceiver Station (BTS) and CATV cable
plant. It converts the PCS frequencies from the BTS to an Intermediate Frequency (IF) to
communicate with its associated CMIs, and it converts the IF signals from the CMIs to PCS
frequencies for the BTS. The HIC uses rear panel connectors to interface with the BTS and
CATV cable plant. One HIC supports multiple CMI units. The HIC assigns each CMI its
frequency and gain levels. Each HIC supports up to three Code Division Multiple Access
(CDMA) channels.
Each HIC consists of a single circuit card assembly (CCA) that contains the components for
the three sector interfaces. A DC-operated fan cools the HIC by pulling air into the front
and exhausting the air via the rear side panels.

1.2.1.4 Cable Assemblies
Cable assemblies provided with the various racks interconnect the installed assemblies
within the rack. Cable assemblies are not provided for external interconnection between
the rack and BTS or CATV plant. Refer to Section 2 for cable assemblies that are provided
with each rack.
1.2.1.5 Equipment Rock
The equipment rack is a standard EIA design that holds and secures standard 19-inch-wide
rack-mounted assemblies. For the PCS-Over-Cable equipment, each rack conﬁguration
uses the identical equipment rack for assembly mounting. The equipment rack dimensions
are:
. Height 76 inches
. Depth 30 inches
n Width 23 inches
- Weight 290 pounds (unpopulated)
1.2.1.6 +24 V Power Supply Assembly
For installation sites that do not provide an external +24V prime power source, an optional
+24V Power Supply, part number 8303743G1, is available for rack installation. The +24V
Power Supply operates using 115 Vac and provides +24V for the rack internal distribution.
(With the power supply installed in a rack, the maximum number of HICs allowed is 12).
1.2.2 Cable Microcell Integrator
The CMI is the communications link between the PCS handset and the CATV cable plant‘
The CMI Assembly, part number 830375061, is comprised of the following major hardware
CMI assemblies:
- Power Extractor Module
- Transceiver Module
' Power Supply Module
0 Power Ampliﬁer Module
- Chassis
The power extractor routes the CATV power to the power supply and CATV cable signals to
the internal CMI transceiver module. The power supply converts the CATV cable plant
power to power levels required on the transceiver module assembly and by the power
ampliﬁer.
The CMI is controlled by the HIC assembly in the HEE. The power ampliﬁer is
enabled/disabled by the assigned HIC unit and is used to boost the CDMA signal sent to
the PCS handset via an antenna. The transceiver module assembly performs the
handshaking with the assigned HIC unit and converts the CDMA signals to the
appropriate frequencies.
The chassis is an environmentally sealed ﬁre enclosure.

VERSION 1.85 IMPLEMENTATION MANUAL Document No. 8337147
1.2.2.1 Power Extractor Module
The Power Extractor is available in two conﬁgurations:
o The SiLigle Mode conﬁguration allows the CMI to operate with both the forward and
reverse link CATV signals on a single CATV interface port (FWD/REV). In this mode
the CMI can be conﬁgured to accept AC prime power from either CATV interface port.
- The W conﬁguration allows the CMI to operate with the forward and reverse
link CATV signals on separate CATV interface ports. The forward link CATV signals
are interfaced to the ALT/FWD CATV interface port and the reverse link CATV signals
are interfaced to the FWD/REV CATV interface port. In this mode the CMI can be
conﬁgured to accept AC prime power from either CATV interface port.
The AC power switch on the Power Extractor allows the installer/maintainer to select AC
prime power for the CMI from either CATV interface port. The AC power switch also allows
the user to shut off AC prime power to the Power Supply module without removing the
Power Extractor.
The Power Extractor features a delay circuit that prevents a power surge on the reverse
link when AC power is applied to the CMI. DC voltage for the delay circuit is routed to the
Power Extractor through an integral two-conductor cable.
The Power Extractor accommodates ﬁeld-replaceable, plug-in attenuator pads for both the
forward and reverse CATV paths, and a ﬁeld—replaceable, plug-in equalizer in the forward
CATV path. These component locations are accessible when the CMI housing cover is open
without the need to remove the Power Extractor. The CMI is shipped with no pads or
equalizer installed. It will accept Scientiﬁc Atlanta model number PP-O to PP-lO attenuator
pads or equivalents and Scientiﬁc Atlanta model number EQ750 equalizers or equivalents.
The Power Extractor routes the following signals:
- External GO-Hz Quasi Square Wave input to the CMI Power Supply Module
- External 5-42 MHz CATV RF Reverse Link signals from the Transceiver Module
0 External 52—750 MHz CATV RF Forward link signals to the Transceiver Module
1.2.2.2 TransceiverModule
The Transceiver contains a dual receiver and a transmitter, and incorporates both analog
and digital signal processing and control. Reverse link RF signals, originating in the PCS
wireless domain, are received by both the primary and diversity receivers, processed and
sent, via the CATV cable plant, to a remote headend location. Forward link signals,
originating at the headend, travel, via the cable plant, to the CMI, are processed by the
Transmitter, ampliﬁed by the Power Ampliﬁer, then broadcast to the PCS wireless users.
There is one LED to indicate +5 Vdc and three LEDs to indicate status codes.
1.2.2.3 Power Supply Module
The Power Supply Module requires a 60»Hz Quasi-Square Wave (45—90 Vrms) input AC
voltage. The power supply produces four DC voltages: +25V, +15V, +5V, and -15V. Test
points are available for all input and output voltages. For overcurrent protection, the AC
input is fused in the Power Supply Module. The fuse is accessible with the power supply
cover removed.

2.4 POWER REQUIREMENTS
Each rack requires external 115V, single phase, 60 Hz, and +24V for prime power. Each
rack has the option of installing a DC power supply in lieu of the external +24V. The +24V
supply is required to operate the installed HICs.
2.4.1 External Prime Power Installation
At the installation site when both 115V, single phase, 60 Hz and +24V are available, a fully
loaded rack with 14 HICs installed requires approximawa 30 amperes for +24V. The
primary rack conﬁguration also requires approximately 2.0 amperes of 115 V, 60 Hz, single
phase power for the HECU assemblies.
2.4.2 Internal Prime Power Installation
If the +24V is not available at the installation site, an optional +24V Power Supply, part
number 8303743G1, is installed in the rack. Each rack uses the internal +24V Power
Supply to power the rack assemblies in the absence of the +24V prime power at the
installation site.
2.4.3 Protective Earth Grounding
The HEE rack(s) must be properly grounded to protect installers and operators from
electrical shock. For this purpose there are two 114 in. x 20 ground studs located on the left
and right rear of the rack ﬂoor panel. The right stud is used to ground the internal
components to the rack. The left stud is used to connect the rack to the site ground The site
grounding cable should consist of UL-approved wire of no less than 14 gauge. The wire
should attach to the ground stud by means of a properly sized ring terminal. The rack is
supplied with a split washer and a 1/4 in. x 20 nut to secure the ground cable ring terminal
to the stud,
2.5 .HEE CONFIGURATION AND SPACE REQUIREMENTS
2.5.1 Suggested Floor Space Regulrements
Figure 2-1 shows the suggested ﬂoor space to support HEE primary and expansion rack
installation, operator work space, and service area.
2.5.2 Typical Rack configuration
Figure 2-2 shows a typical rack conﬁguration as it appears before installation of the HECU
and individual HICs. Both rack conﬁgurations use the identical equipment rack. The rack
is 76 inches high, 30 inches deep, and 23 inches wide. A minimum of 36 inches of clear
space behind the rack is recommended for servicing and proper ventilation. As shown in
Figure 2-3, the primary rack conﬁguration contains the HECU. For this conﬁguration,
when the HECU keyboard tray is extended, another 40 inches is suggested for operator
workspace. It is recommended that the rack be bolted to the ﬂoor.
When the optional +24V Power Supply is installed in the racks, it occupies the two top
positions (the two top panels), thereby reducing the maximum number of HICs per rack
from 14 to 12.

2.6 INSTALLATION OF ASSEMBLIES IN EQUIPMENT RACK
Paragraph 2.6.1, Primary Rack Installation, provides step-by-step instructions for
installing hardware assemblies, cables, wiring, etc. Since the installation instructions for
the two rack conﬁgurations are similar, paragraph 2.6.2 covers only the differences
between installation of the expansion rack and the primary rack and references paragraph
2.6.1 for installation procedures.
2.6.1 Primag Flack Installation
For installation sites that do not provide an external +24V power source, an optional
internal +24V Power Supply , part number 8303743G1, must be installed in the primary
rack. Paragraph 2.6.1.1 gives the instructions for modifying the rack to install the +24V
Power Supply. If the installation site provides +24V power, proceed to paragraph 2.6.1.3.

2.6.3.5 CATV Headend Measurements
This procedure measures the HIC Downstream levels at the Headend input prior to
connecting to the CATV headend. It veriﬁes that the losses from the HIC to the Headend
are not excessive and that the level will not interfere with the live CATV network.
Downstream ampliﬁcation may he added at the Headend if required
a. Observe the Downstream signal at the Headend, after Video Combining. Verify
that the Reference Tone amplitude is 15 dB below the Video Reference Level.
1) If the level is within 5 dB of the required level, adjust the attenuation at the
REFERENCE AND CONTROL TONES dialog.
2) If the level requires more than 5 dB of adjustment, install the appropriate
device (ampliﬁer or attenuator) between the HIC output and the Headend
input to reduce the error to less than 5 dB, then adjust the Attenuation
Setting at the REFERENCE AND CONTROL TONES dialog.
3) Record the ﬁnal amplitudes and settings for:
— Reference Tone amplitude
— Reference and Control Tone attenuator setting
- Video Reference Level
b. Observe the Downstream CDMA signal at the Headend, after Video Combining.
Verify that the Downstream CDMA Pilot Level is 22 dB below the Video
Reference Level.
2) If the level is within 5 dB of the required level, adjust attenuation at the HIC
DOWNSTREAM POWER Dialog.
3) If the level requires more than 5 dB of adjustment, install the appropriate
device (ampliﬁer or attenuator) between the HIC output and the Headend
input to reduce the error to less than 5 dB, then adjust attenuation at the
HIC DOWNSTREAM POWER Dialog.
4) Record the CDMA Pilot Level.
5) Record the final Downstream attenuator setting.
c. If a CMI is installed for use with this HIC, proceed with CMI installation
checkout, otherwise, continue installing HIC/BTSICable Plant cabling.
d. If alarms occur and the cable plant/BTS signals are connected and at the correct
levels, refer to Table 2-6 for a list of the alarms recognized by the HECU

3.3 CMI HARDWARE INSTALLATION GUIDE
MBNINQ
Potentially dangerous High Voltage exists on the AC
power cable to the CMI Assembly that could cause
bodily injury or even death. During a line surge or fault
condition, High Voltage also could be present on the
antenna connectors. Use extreme care and required
safety precautions while Working on the CMI
installation and handling the AC power cable.
To avoid any possibility of overexposure to RF emissions
when working near a CMI, maintain a minimum
distance of eight inches from the transmitting antenna.
3.3.1 CATV Cable Interface to the CMI
CATV coaxial cable typically connects the CMI to the CATV cahle plant through a
directional coupler referred to as a cable tap. Each CMI uses a separate tap, with tap
coupling varying according to the tap location in the cable plant.
AC voltage supplied by the cable plant is present on the coax center conductor along with
the RF signals. The CMI internal Power Extractor routes the AC voltage to the CMI Power
Supply and routes the reverse link and forward link RF signals between the cable plant
and the appropriate CMI Transceiver ports.
3.3.2 CMI Access
3.3.2.1 Ogening the Assembly
WARNING
The CMI hinged cover (road side) contains the Power
Supply and therefore is heavy. If a CMI must be opened in
the installed position, always support the cover with one
hand when releasing the last captive screw to avoid
equipment damage and/or personal injury.
The hinged CMI Assembly housing is secured with eight captive bolts. Place the CMI on
any ﬁrm surface and release the bolts, using 5 1/2-inch socket Wrench. Open the cover
carefully, keeping in mind that the cover (road side) portion contains the Power Supply and
therefore is heavy.

CAUTION
When closing the CMI Assembly, ensure that all internal
wiring is clear of the housing seal before securing captive
screws to avoid possible equipment damage.
NOTE
To restore the watertight seal on a. CMI Assembly, the
captive bolts must be torqued to 140-145 in-lb, in the
proper sequence.
Place the CMI Assembly on any ﬁrm surface. Carefully close the cover, ensuring that all
internal wiring is clear of the housing seal. Torque the eight captive bolts to 140—145 in-lb,

There are two possible port conﬁgurations, each using either a hausing-to-F adapter or a
housing-tovhardline connector. One or both ports are used, based on installation
requirements. The housing-to—F adapter or the housing-to-hardline connector (shown in
Figure 34) is threaded into the CMI housing, with its center conductor secured to the
internal CMI circuits by a seizure screw. The seizure screw is accessed by removing a
threaded plug located at the rear of the CMI chassis (curb side).The seizure screw is
tightened using a medium ﬂat-blade screwdriver.

Figure 3-4. Typical Housing Adapter Interface
One conﬁguration uses only the FWD/REV port and the other uses both the FWD/REV and
ALT/FWD ports. Either port can accept AC voltage from the cable plant for the CMI. The
FWD/REV port must be used to carry reverse link signals and can carry forward link
signals. The ALT/FWD port may be used as an alternate to FWD/REV for forward link
signals.
\ 5/5 x 24 THREAD
If the installation requirements dictate the use ofhousing-to F-adapter(s), it is strongly
recommended that the adapter installation be performed on the ground prior to installing
the CMI on the cable strand.
The assembly sequence of CATV coax and housing-to-hardline adapter to CMI is
determined by mechanical constraints. Figure 3-5 shows an exploded view of these items.
The housing-to-hardline adapter must be threaded into the CMI housing; therefore, it must
be separate from the CATV coax during installation or removal. The seizure screw is
tightened against the housingto-hardline adapter center conductor after the adapter is
installed. The CATV coax is joined to the housing-to-hardline adapter after the adapter is
secured to the CMI. The adapter must he torqued to 30 in-lb.

3.3.3.2 Power Extractor Options
The CMI is supplied from the factory with either a Single-Mode or a Dual-Mode Power
Extractor. The Single-Mode conﬁguration allows the CMI to operate with both the forward
and reverse link CATV signals on the FWD/REV interface. The Dual-Mode conﬁguration
allows the CMI to operate with the forward link CATV signals interfaced to the ALme D
interface port and the reverse link CATV signals interfaced to the FWD/REV interface port.
With either conﬁguration, the CMI can be conﬁgured to accept AC prime power from either
CATV interface port.
The Power Extractor module is shown in Figure 3-6. The outward appearance of the two
conﬁgurations is identical except for the serial number (visible without removing the Power
Extractor from the CMI): The eighth digit of the serial number for the single-mode
conﬁguration is always 1, while the eighth digit of the serial number for the dual-mode
conﬁguration is always 2, (The seventh digit of the Power Extractor serial number is
always 2.) For example, serial number 969T00210000 indicates a single—mode
conﬁguration.
The Power Extractor accommodates ﬁeld»replaceable, plug-in attenuator pads for both the
forward and reverse CATV paths, and a ﬁeld-replaceable, plug-in equalizer in the forward
CATV path. These component locations are accessible when the CMI housing cover is open
without the need to remove the Power Extractor. The CMI is shipped with no pads or
equalizer installed. It will accept Scientiﬁc Atlanta model number PP—O to PP-10 attenuator
pads or equivalents and Scientiﬁc Atlanta model number EQ750 equalizers or equivalents.
3.3.3.3 Ac Power Connection Options
The AC voltage supplied by the cable plant can be connected to the CMI through either
CATV port. The position of the switch on the Power Extractor (see Figure 3-6) controls
which port provides the AC voltage: The FWD/REV UP/DOWN position provides AC power
through the FWD/REV port, and the ALT/FWD ALT/DOWN position provides it through
the ALT/FWD port. The OFF position removes prime power from the CMI starting at the
Power Extractor output. Refer to paragraph 3.3.2 for CMI access instructions.
AC voltage is routed from the Power Extractor to the AC input connector on the Power
Supply via an integral cable with keyed 5-pin connector. The Power Supply AC input
connector is shown in Figure 3-7.

adjusting CATV video reference level.
g. At FWDTEST test point, verify that HIC forward link Reference Tone level is
approximately -26 dBmV : 5 dB. Record this level and pad value.
h. Replace FWDTEST test point CATV plug, and close CMI per paragraph 3.3.2.
3.6 REVERSE LINK CMI INSTALLATION MEASUREMENTS AND ADJUSTMENTS
3.6.1 U stream Gain Ad ustment
This procedure determines the upstream pad value in the CMI power extractor module in
order to set up a consistent upstream gain between the CMI and its corresponding cahle
plant ﬁber node with respect to all other CMIs on the CATV network Therefore, when all
CMIs are set to the operating upstream setpoint level, they will operate at roughly the
same upstream output power level.
NOTE
The Upstream Gain Adjustment procedure assumes
that all ﬁber nodes on the reverse link of the CATV
Plant have been adjusted for a consistent gain between
Fiber Node and HIC, in preparation for CMI
deployment.
3.6.1.1 Adjusting Upstream Gain at the CMI Site
a, Open CMI per paragraph 3.3.2. Verify that both attenuator pads and equalizer
pad, 0 dB or other calculated values, are installed in Power Extractor.
h. Remove the REVTEST CATV plug from CMI.
c. Insert a Long Reach Test Point Adapter through access hole to mate ‘with Power
Extractor test point.
d, Connect a Type F test cable between Long Beach Test Point Adapter and test
signal generator 75-ohm output.
e. Inject a CW signal into the CMI REVTEST port at the assigned upstream CATV
frequency for the CMI, using a power level 0f+40 dBrnV.

f. After the measurements and calculations are made at the headend, insert
attenuator pad of calculated value into REV/UP AT'I'EN receptacle of Power
Extractor,
g. Replace REV‘TEST test point CATV plug, and close CMI per paragraph 3.3.2.
3.6.1.2 Adjusting Upstream Galn at the HIC
a. Connect a Type F test cable to a spectrum analyzer (75 0 input).
b. Connect a Type F test cable to the HIC UPSTREAM TEST POINT of
appropriate sector for CMI being measured.
c. Set up spectrum analyzer to upstream frequency for CMI being adjusted and
measure injected CW signal.
d. Perform a peak search or set marker to CW signal to be measured. Record the
power level (in dBmV).
NOTE
Given the injected level at the CMI of +40 dBmV, the
nominal level of the CW signal expected at the HIC test
port is -35 dBmV. This value assumes 35 dB of cable
plant loss between the upstream ﬁber node and the HIC
input and 40 dB of combined loss for the CMI and HIC
test ports: +40 dBmV injected power level at the CMI
Test Port minus 75 dBmV of total loss = -35 dBmV.
e. Determine attenuator pad necessary to adjust the upstream gain between the
CMI and ﬁber node using the following equation:
(Measured CW Level) - (-35 dBmV nominal level at HIC Test Port) = UP pad value
f. . Have CMI technician install an attenuator pad with the calculated value in
REV/UP A’I'I‘EN receptacle of Power Extractor.
3.6.2 Actlvate CMI
This procedure, also referred to as CMI acquisition, adds the selected CMI to the database
for monitoring and control by the HECU via the assigned HIC. The procedure also shows
that the HIC and CMI are communicating and that all cable interconnections appear to be
satisfactory.
a. Ensure that Headend primary rack is turned on and appropriate HIC is active.
h. At HEADEND CONTROL PANEL dialog, select Alarms, then CMI Out Of
Service Control.
c. At CMI OUT OF SERVXCE dialog, select gut 91 Service Indicator OFE to
disable all Out Of Service alarms, then select QK.

NOTE
Aﬁer all CMIs installed for a given sector or node have
been checked and adjusted individually per the
procedures above, perform the following procedures for
all CMIs assigned to a given HIC.
3.6.5 Setting CMI Reverse Link Signal Level Setmint at H":
This procedure, or the alternate procedure in paragraph 3.6.7, is used to determine the
target reverse link (upstream) output level for all the CMls assigned to a given HIC in a
given sector. This target level is otherwise known as the upstream autogain setpoint. The
ideal target level for a single CMl in a simulcast will depend on the number of CMIs in the
simulcast.
a. Measure the reverse link video reference at HIC UPSTREAM TEST POINT for
sector of interest (Alpha, Beta, Gamma). Record this value.
h. At HEADEND CONTROL PANEL dialog, select Alarms, then CMI Out Of

disable all Out Of Service alarms, then select QK.
d. At HEADEN'D CONTROL PANEL dialog, select the ﬁrst HIC to be worked on.
e. At HIC CONTROL PANEL dialog, select CMI Group Qt] and disable all
functions except Alarms for all sectors that have CMIs attached, then select QK.
f. At the HIC CONTROL PANEL dialog, select WWW.
g. With all CMIs disabled, at appropriate HIC UPSTREAM TEST POINT, measure
reverse link CATV noise ﬂoor over intended frequency range. (The noise ﬂoor at
this point will represent the combined noise effects of each ﬁber node in the
' sector)
h. Calculate the Rough Target for a single CMI by the following formula:
Rough Target = Video Reference - 3] - 1010g(n)
where n is the number of CMls in the sector. Record this value.
e. If Rough Target is less than 5 dB above CATV noise ﬂoor, then alternate
balancing method must be used (paragraph 3.67).
f. If Rough Target is greater than or equal to 5 dB above the noise ﬂoor, proceed to
the Upstream Setpoint Initialization procedure, paragraph 3.6.6.
3.6.5 Umream Setgolm Initialization
a. At HIC CONTROL PANEL dialog, select Sector and CMI to be set.
b. Connect Spectrum Analyzer to appropriate sector UPSTREAM TEST POINT on

Analyzer.
f. Observe the average levels of Primary and Diversity pedestals If one is below
the Rough Target Display Line, increment UP the appropriate setpoint control in
the US SETPOINT INITIALIZATION dialog to move Upstream pedestal near
mid-screen. If one is above the Rough Target Display Line, increment DOWN the
appropriate setpoint control. (Each increment of the Up/Down indicator is equal
to approximately 0.5 dB).
Select update button.
h. Observe Status indicator: It is red while updating is in progress and turns green
when the update is complete. Wait a few moments for new Upstream Setpoint to
take effect, then observe Spectrum Analyzer to determine if another adjustment
is required. Continue this process until the ﬁnal US Setpoint selected produces
pedestal levels that average out to Rough Target value 1 0.25 dB.

. At the CMI OUT OF SERVICE dialog, select Mergigelndigamr—Oﬂ and
select all desired alarms, then select QK.
Alternate Balancing Method
In some cases the target level of a single CMI may be close to—or even beneath—the
combined CATV noise ﬂoor. In these cases the pedestal cannot be used to balance the CMI.
Instead a test signal is used.
a. At HIC CONTROL PANEL dialog, select Stop U5 setpoint Initialization.
b. At CMI UPSTREAM POWER dialog, activate desired CMI by enabling receivers
and setting combined reverse link attenuators to nominal values: Primary: 5;
Diversity: 5; Combined: 44.
. With spectrum analyzer connected to the HIC upstream test point of interest,
verify that pedestals are at least 10 dB above noise ﬂoor. If necessary, adjust
attenuator settings at CMI UPSTREAM POWER dialog.
. At CMI CONTROL PANEL dialog, select Bing. At the resulting PING CMI
dialog, enable test signals on desired CMI.
. Measure power levels of the two test signals and average power of pedestals.
Record these values.
Calculate power difference between the test signals and the pedestals, Record
these values.
. Calculate ﬁnal target levels for the two test signals of a single CMI by adding
Rough Target level—measured in paragraph 3.6.5—to the difference between
test signals and the pedestals. (In this way, the test signals are used to gauge
when the pedestals are at the desired setpoiut for the sector, since the
appropriate level is too close to the noise ﬂoor to be accurately measured. Note
that there will be a separate target level for each CMI signal, Primary and
Diversity.) Record ﬁnal target levels.
. With a single CMI enabled, enable test signal and adiust upstream attenuators
at CMI UPSTREAM POWER dialog until both primary and diversity test signals
are at desired target level. Save these attenuator settings to EEPROM, and
record these values.
At TRANSCEIVER CONTROL dialog, disable all functions for CMI just
adjusted.
Repeat this procedure for each CMI in sector.
