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:
a Computer, Rack Mountable Pentium 100 MHz
- Monitor, Rack Mountable
- Keyboard, Rack Mount
0 Mouse, PS/2
. Computer Power Cord
0 Monitor Power Cord
The HECU monitors and controls the CMI and BIG 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 Hle over an 125-485 interface via a Lonworks® card
located in the computer.
The major software HECU components are:
0 Microsoft® DOS Version 6.22
. Microsoﬁ® Windowsm 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 +24V and 15-MHz input for operation. The distribution assembly accepts a single
lS-MHz input from the Base Transceiver Station (BTS) and provides 16 reference outputs
for distribution to the HICs. 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 BIG 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 Hack
The equipment rack is a standard ELA design that holds and secures standard lB-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:
0 Height 76 inches
- Depth 30 inches
- 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 H105 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 8303750G1, is comprised of the following major hardware
CMI assemblies:
- Power Extractor Module
0 Transceiver Module
- Power Supply Module
- Power Ampliﬁer Module
0 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.

1.2.2.1 Power Extractor Module
The Power Extractor is available in two conﬁgurations:
- The Single Made 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 Dual Mode 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-IO attenuator
pads or equivalents and Scientiﬁc Atlanta model number EQ750 equalizers or equivalents.
The Power Extractor routes the following signals:
- External 60-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 TranscelverModu/e
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 Vrrns) 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 overeat-rent protection, the AC
input is fused in the Power Supply Module. The fuse is accessible With the power supply
cover removed.

2.6.2 Expansion Rack Installation
An expansion rack may be used in conjunction with the primary rack. The expansion rack
houses and provides the site with additional HIC units. The major difference between the
primary and expansion rack is that the expansion rack does not contain an HECU and
certain cable assemblies. Therefore, the expansion rack must interface with a primary rack
for operation.
The rack installation procedures in the previous are applicable to the expansion rack
conﬁguration as well, with few differences. Table 24 lists the installation procedures
applicable to the expansion rack. Differences in the procedure that affect expansion rack

2.7.6 Cable Installation Between HIC, BTS and Cable Plant
The following are recommended procedures for interconnecting the BIOS with the BTS and
the cable plant Headend.
NOTE
The cables needed for a full rack occupy a great deal of
space and can interfere with normal equipment
servicing by obscuring view and blocking access. As each
HIC is installed, special care should be taken to bundle
and route the cables in a manner that minimizes the
space used.
2.7.6.1 CDMA Forward Link Input from BTS
rl'he BTS provides the CDMA forward link input signal to the installed HICs. Each installed
HIC is divided into three sectors, designated alpha, beta, and gamma. The sectors operate
independent of each other, communicating over separate cables with three BTS sectors,
also designated alpha, beta, and gamma
CAUTION
Because some BTS units are capable of generating an
extremely high forward link power level, it is important
to measure the forward link output of the BTS prior to
connecting it to the HIC input.
a. Connect a Forward link RF cable to the alpha sector (SI) Forward link CDMA
output port of the BTS and route the cable over to the vicinity of the selected
HIC in the HEE rack. Do not connect the cable at this time.
b. Secure the cable to the appropriate cable troughs to eliminate any strain on the
cable connectors.
0. Using a spectrum analyzer, measure the power level at the output of the cable.
Verify that the CDMA Forward link input level from the Alpha sector of the BTS
is between +3 dBm and -9 dBm (Pilot only) at the input to the HIC in the HEE
rack. (CDMA levels are to be measured in a 1,23-MHz bandwidth.)
d. After the level has been verified, connect the Forward link cable between the
BTS alpha sector and the D/S alpha BTS IN port on the rear panel of the
selected HIC (Figure 2-9).
e. Repeat steps a through 2 for the beta and gamma sectors to complete one
HIC/BTS pair (The BTS beta sector is $2 and the gamma sector is S3.)

3.3 CMI HARDWARE INSTALLATION GUIDE
WARNING
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 cable 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 Ogenlng the Assembly
WARNING
The CMI hinged cover (road side) contains the Power
Supply and therefore is heavy. If a CM] 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 a 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.

3.3.2.2 Closing the Assembly
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

3.3.3.1 CMI CATV Part Configurations
There are two possible port conﬁgurations, each using either a housing-to-F adapter or a
housing-to-hardline 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 3-4) 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.

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.
If the installation requirements dictate the use of housing-h) F-adapteﬂs), 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 housing-to-hardline adapter center conductor aﬁer the adapter is
installed, The CATV coax is joined to the housing-to-hﬂrdline adapter after the adapter is
secured to the CMI. The adapter must be 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 ALT/FWD
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 mode] number PP~0 to PP-IO attenuator
pads or equivalents and Scientiﬁc Atlanta model number EQ750 equalizers or equivalents.
3.3.3.3 AC Power Connection Optlons
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.

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 cable
plant ﬁber node with respect to all other CMIs on the CATV network. Therefore, when all
CMls 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.
3.5.1.1 Adjusting Upstream Gain at the CMI Site
a. Open CMI per paragraph 332. Verify that both attenuator pads and equalizer
pad, 0 dB or other calculated values, are installed in Power Extractor.
b. 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 Reach 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 of+40 dBmV.

1". After the measurements and calculations are made at the headend, insert
attenuator pad of calculated value into REV/UP A’I'I'EN receptacle of Power
Extractor.
g. Replace REVTEST test point CATV plug, and close CMI per paragraph 343.2.
Adjusting Upstream Gain at the HIC
3. Connect a Type F test cable to a spectrum analyzer (75 Q 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
3.5.2
£ . Have CMI technician install an attenuator pad with the calculated value in
REV/UP A'l'l‘EN receptacle of Power Extractor.

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 setpoint 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.
