♦ High leakage current: The Hub rack, internal or external (environmental) enclosure
must be connected to Protective Earth ground before any connection is made to +24
VDC prime power.
♦ High Voltages (110/220 VAC and 24 VDC) are present within the Hub rack or
environmental enclosure. Use extreme caution when working inside the
rack/enclosure.
♦ High voltages may exist close to the CMI location; use standard electrical industry
safety practices when working on an installed CMI.
♦ High voltages (110/220 VAC RMS) exist on the AC power input to the CMI. Use
extreme caution when removing the AC power cable to avoid coming in contact with
the center conductor.
♦ Laboratory tests conducted in accordance with ANSI/IEEE C95.1-1992 show that a
transmitting CMI poses no radiation hazard to persons in close proximity to the
transmitting antenna. However, for added safety when working near a CMI,
maintain a minimum distance of 12 inches from the transmitting antenna.
ESD CAUTION
The CMI contains circuit card assemblies that are sensitive to
Electrostatic Discharge (ESD) damage. Whenever handling the CMI, use
ESD precautionary procedures to minimize the risk of permanent ESD
damage to circuit card components. Low relative humidity level increases
the potential for damage to ESD-sensitive devices.

1.2.3 Notation Conventions in this Manual
This manual assumes that the user has a basic knowledge of the Windows NToperating
system. Several typographic conventions and standard Windows NT terms are used in
this manual when discussing the TransCell Network Manager software. They are as
follows:
Mouse Commands - The TransCell Network Manager software uses only the left mouse
button:
♦ “click” - press and release the left mouse button
♦ “double-click” - press and release left mouse button twice in quick succession
Menu Commands - Menu commands are bolded with each command level separated from
the previous one by a slash (/) mark, e.g., “Select Privileges/Modify Privileges.”
Button Names – Command button names in dialogs are underlined, e.g., “To confirm
selection, click OK.”
Key Names - Key names are spelled out and appear in small, bold capital letters, e.g.
ENTER, ESCAPE, AND CONTROL.
Dialogs and Messages - Dialog and message titles appear in all upper case (capital) letters,
and generally the name is referenced exactly as shown on the title bar, e.g., the PCS
FREQUENCY dialog. However, in cases where the dialog title varies according to privilege
level, enclosure, or sector, the title is shortened to exclude this variable information unless
the variable is important. If a dialog title is referenced that includes a specific HIC or CMI
number, the number is represented by the bracketed letter n: e.g., CMI CONTROL
PANEL: ALPHA SECTOR, CMI [n].
Dialog Options - Dialog options (text boxes and radio buttons) are shown in italics, e.g.,
“Type in the desired PCS Frequency.” All instructions to “select” or “choose” an option
imply clicking on that option, although options can be selected via the keyboard as well.
Keyboard Input - Instructions for keyboard entries start with “Type in...”, and anything
that should be typed in verbatim is shown in a contrasting font. For example, “Type in
config01.dtb in the File Name box.”
Displayed Text - Text displayed in a dialog box is shown in another contrasting font, e.g.,
“The CONFIGURATION OPTIONS dialog displays the query “Do you Want To Restore
a Pre-existing Configuration?”.

1.4 SYSTEM OVERVIEW
The TransCell 1900CB system permits the transport of CDMA PCS signals between a Base
Transceiver Station (BTS) and mobile users over fiber/coaxial cable infrastructures. The
cable network (fiber, coax, or hybrid) is used to distribute the PCS signals between the
cable Hub or hub facility and attached remote locations throughout the service area.
The TransCell 1900CB system has four primary components: Cable Microcell Integrator
(CMI), Hub Interface Converter (HIC), RF Interface Assembly (RFIA), and Hub Control
Unit (HCU) and two fiber optic peripherals: Hub Fiber Interface (HFI) and Remote Fiber
Interface (RFI). The HICs and CMIs provide the carrier frequency translation and signal
conditioning needed for the CDMA signal (single carrier or three-carrier) interfaces
between mobile user, BTS, and fiber/coaxial network. The HCU provides the operation,
administration, and maintenance (OA&M) functions for the system. The RFI and HFI
provide the conversion between light and RF energy.
As shown in Figure 1-1, in the reverse path a CMI at a remote location receives a CDMA
signal from a mobile PCS unit via the receive antennas, converts its PCS carrier frequency
to an IF frequency and sends the signal to the associated HIC at the Hub. The HIC
converts the signal carrier back to the PCS frequency and routes the signal to the BTS. The
BTS then switches the signal into the telephone network.
In the forward path, the process is inverted. The HIC receives the CDMA signal from the
BTS, translates the carrier frequency to an IF frequency and sends the signal to the CMI.
The CMI translates the signal carrier back to the PCS frequency, amplifies the signal, and
radiates it via the transmit antenna for capture by the mobile PCS unit. One HIC provides
the BTS interface for up to three CDMA sectors and may control as many as 30 CMIs.
The HICs and CMIs normally handle the transport of PCS traffic over the fiber/coaxial
network without assistance from the HCU. The HCU is used to set up frequency,
attenuation, and fault reporting parameters and to change those parameters as needed. In
normal operation, the HCU allows operators to monitor system operational status and
alarms.

For installations with existing environmentally controlled indoor Hub or hub facilities, the
typical TransCell 1900CB configuration consists of up to three Hub Equipment (HE)
enclosures stacked, containing a HCU, three Hub Fiber Interface Units (HFIs), three RF
Interface Assemblies (RFIAs), and three HICs. Additional enclosures may be purchased
when more than three HICs are required at a given site. Each HIC is connected to several
CMIs which are installed on the outside fiber/coaxial network.
For ruggedized outdoor installations, the HCU and HICs are housed in an outdoor
environmental controlled enclosure.
Either the indoor or outdoor system installation may also include a network interface unit
to remote the HCU for centralized monitoring and control of PCS network operation.
1.4.1 Hub Equipment (HE) Enclosure Configurations
The HE enclosure contains these major components:
♦ Hub Control Unit (HCU)
♦ RF Interface Assembly (RFIA)
♦ Hub Interface Converters (HICs)
♦ Hub Fiber Interface Unit (HFI) (Optional)
♦ +24 VDC Power Supply (Optional)
There are three stackable enclosure configurations available. One enclosure houses the
HCU (PC, Monitor, and Keyboard). The second enclosure houses an RFIA, HIC, HFI
(optional), Power Supply (Optional), and a network interface box (remote configuration
only). The third enclosure houses two RFIAs, two HICs, and two HFIs (Optional). Section
2 of this manual contains a detailed assembly list for each enclosure configuration. The
following paragraphs describe the major assemblies that are normally installed in the
configurations along with some optional assemblies.
1.4.1.1 Hub Control Unit (HCU)
The HCU is installed in one Hub equipment enclosure. A single HCU supports up to 26
HICs. The HCU may also be installed in a central location (NOCC) and remoted to an
outside enclosure. This configuration is used for those installations in uncontrolled
environments. The major HCU hardware components are:
♦ Computer chassis
♦ Color CRT Monitor
♦ Keyboard/Touchpad/Mouse
The HCU is the monitoring and control device for the attached HIC units and their
assigned CMIs. It monitors various system parameters to verify that these units are
operational and that signal power is being maintained at the proper levels. The HCU
communicates with the HICs over an RS-485 interface via a LonWorks® card located in the
computer, and through the HICs it communicates with the CMIs. The HCU interprets all
faults reported by the HICs and CMIs into alarms, which are logged and displayed. The
computer also contains one or more modems for remote monitoring and control of the HCU
located at a central control point.

The major HCU software components are:
♦ Microsoft® Windows NT
♦ pcANYWHERE Version 8.0 or later (optional)
♦ TransCell Network Manager software
♦ Software drivers for custom HCU functions
1.4.1.2 RF Interface Assembly (RFIA)
The RFIA provides a transition from the larger and more rigid cables from the BTS and
cable plant to smaller and more flexible cables for connecting the HICs. It also provides a
stable 10 or 15-MHz reference signal for the HICs.
Depending on the site requirements these RFIA configurations provide duplexing of the RF
signals between the HIC and the BTS and the cabling between the HIC and HFI or
Fiber/Coaxial Network. One RFIA is required for each HIC installed in the enclosure(s).
Each RFIA requires +24 VDC for operation. For more detailed description and installation
instructions, see Appendix A.
1.4.1.3 Hub Interface Converter (HIC)
The HIC is the direct interface between the RFIA and Fiber/Coaxial network. It processes
up to three forward link sector of CDMA PCS signals (single carrier or three carriers) and
up to three pairs of diversity reverse link CDMA PCS signals (single carrier or three
carriers). The HIC converts the PCS frequencies from the BTS to an intermediate
frequency (IF) suitable for transmission over fiber/coaxial cable to 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 RFIA and HFI or coaxial cable network. Each
HIC supports up to 10 CMIs on each of three CDMA sectors (up to 30 CMIs total per HIC).
The HIC assigns each CMI its frequency and gain levels.
Each HIC consists of two-circuit card assemblies that contains the components for the
three sector interfaces and the digital circuitry. A DC-operated fan cools the HIC by pulling
air into the front and exhausting the air via the rear side panels.
1.4.1.4 Hub Fiber Interface (HFI)
The HFI is an interface unit that converts IF CDMA signals to/from light and interfaces
the HIC with the fiber network. The HFI contains three independent fiber optic
transceivers that may be configured to support multiple fiber optic networks. Typical
configurations are one HFI per HIC since one sector is typically designated to a
geographical area and each HIC supports three sectors. The HFI power source
requirements is +24VDC. Each fiber optic transceiver unit contains a separate laser on/off
lockable switch located on the front panel of the unit.
1.4.1.5 Cable Assemblies
Cable assemblies provided with each enclosure interconnect the installed assemblies
within the enclosure. Cable assemblies are not provided for external interconnection
between the enclosure and BTS or fiber/cable network. Refer to Section 2 for a list of cable
assemblies provided with each enclosure configuration.

1.4.1.6 Equipment enclosure
The indoor and outdoor equipment enclosure is a standard EIA design that holds and
secures standard 19-inch-wide enclosure-mounted assemblies. The equipment enclosure
dimensions are:
Indoor Enclosure Outdoor Enclosure
♦ Height 24 inches 39 inches (minus lift brackets)
♦ Depth 25 inches 26 inches
♦ Width 20 inches 24 inches
1.4.1.7 +24 VDC Power Supply Assembly (Optional)
For installation sites where an external +24 VDC prime power source is unavailable, an
optional +24 VDC Power Supply is available for enclosure installation. The +24 VDC Power
Supply operates on either 110 or 220 VAC. The +24 VDC Power Supply will be used to
power all three of the HICs installed in an enclosure.
1.4.2 Remote Fiber Interface (RFI)
The RFI is a fiber node. The unit contains a fiber optic transceiver and an AC
(110/220VAC) to DC power supply. The RFI resides at the demarcation point, between the
Hub HFI and a network of Coaxial CMIs, where the fiber no longer is available and coaxial
cable must be extended to the CMIs.
1.4.3 Cable Microcell Integrator (CMI)
The CMI is the communications link between the PCS handset and the fiber/cable network.
It processes a single forward link and single pair of diversity reverse link CDMA PCS
carriers (single carriers or three-carriers). Each CMI is controlled by its assigned HIC. The
CMI is comprised of the following major hardware assemblies:
♦ Power Extractor - routes the tapped coaxial IF CDMA signals to/from the RF
Transceiver in a coaxial CMI.
♦ Internal Fiber Interface – converts light to/from the IF frequencies to/from the RF
transceiver in a fiber CMI.
♦ Transceiver - responds to control messages from the assigned HIC and converts the
CDMA signals to the appropriate transmission frequencies.
♦ Power Amplifier - enabled/disabled by the assigned HIC; boosts the CDMA signal
sent to the PCS handset via an antenna.
♦ Power Supply - converts the 110/220VAC power to the DC voltages required by the
Transceiver, Internal Fiber Interface, and Power Amplifier.
♦ CMI Housing Assembly - environmentally sealed fireproof enclosure for all of the
four CMI assemblies.
♦ Antennas – one transmit and two receive, typically omnidirectional. Antennas are
optionally available from Transcept, depending on customer preference.

1.4.3.1 Power Extractor
The CMI Power Extractor is available in two configurations:
♦ Single (or Combined) Mode, Sub-Split: Basic frequency range - 5 to 42 MHz
♦ Single (or Combined) Mode, Mid-Split: Extended frequency range - 5 to 52 MHz
The Power Extractor routes the following signals:
♦ Reverse link signals from the Transceiver module, 5 to 42 MHz (basic) or 5 to 52
MHz (extended)
♦ Forward link signals to the Transceiver module, 450 to 750 MHz
NOTE
References to reverse link frequency range in this manual imply a range of 5
to 52 MHz. However, if a single mode sub-split (basic) Power Extractor
module is installed in a CMI, the range for that CMI will be 5 to 42 MHz.
The relationship between the Power Extractor configuration and the way in which the CMI
is electrically connected to the coaxial cable is as follows:
♦ The Single Mode is configured to operate with both the forward and reverse link
signals on a single interface port (FWD/REV). The CMI is configured in this mode
by installing the Single Mode, Sub-Split (basic frequency range) or the Single Mode,
Mid-Split (extended frequency range) Power Extractor module.
The Power Extractor accommodates field-replaceable, plug-in attenuator pads for both the
forward and reverse paths, and a field-replaceable, plug-in equalizer (should be zero for
typical installations) in the forward 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
numbers PP-0 to PP-10 attenuator pads, or equivalent, and Scientific Atlanta model
number EQ750 equalizers, or equivalent.
1.4.3.2 Internal Fiber Transceiver
The Internal Fiber Transceiver converts 1310nm-laser light to IF energy that feeds the RF
Transceiver in the forward direction. In the reverse direction, the unit converts IF energy
from the RF Transceiver to 1550nm light (2mW max). The power interface to the Internal
Fiber Interface is DC power coming from the power supply. The fiber optic cable is
connected to the fiber network via a coupler and passes through a housing interface and
connected directly to the Internal Fiber Transceiver.

TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE PAGE
1.4.3.3 Transceiver
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 coaxial/fiber network, to a Hub location. Forward link signals, originating at
the Hub, travel via the coaxial/fiber network to the CMI where they are processed by the
transmitter and sent to the Power Amplifier.
The Transceiver has four LED indicators on its outer surface, clearly visible when the CMI
cover is open. One LED is normally lit to indicate presence of +5 VDC power, while the
other three are normally unlit. These three LEDs light only to indicate particular
Transceiver fault conditions. The Transceiver is available in three different PCS frequency
band sets (A/D, B/E, C/F) (see Table 3-2); the desired band set is selected at the time of
order.

TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE PAGE
1.4.3.4 Power Supply
The Power Supply requires a 110/220VAC, 50/60-Hz voltage input. It produces four DC
voltages, +25V, +15V, +5V, and -15V, for use by the Transceiver and Power Amplifier. For
overcurrent protection, the Power Supply AC input is fused. The fuse is accessible with the
power supply cover removed.
1.4.3.5 Power Amplifier
The Power Amplifier operates in one of three 20-MHz pass bands corresponding to the
selected Transceiver frequency band for a single carrier CMI. For a multi-carrier (three)
unit, the power amplifier covers the entire 60MHz pass band. Power Amplifier parameters
include:
• Gain Approximately 60 dB
• Power Output +35.0 dBm/+39.0dBm max
• Power Output Dynamic Range 15 dB minimum
1.4.4 CMI Antennas
The CMI requires three antennas for operation: two receive and one transmit. For typical
aerial operation, 6-dBi gain antennas, approximately 8 inches in length, are used. The
receive antennas are installed on brackets and extend below a messenger strand. The
transmit antenna is installed on a bracket and extends above a messenger strand. A
separation of six feet between the diversity receive antennas is recommended to achieve
reasonable spatial diversity. The use of the 6-dBi gain antennas with a minimum transmit-
to-receive antenna distance of 36 inches will achieve the required transmit-to-receive
antenna isolation in excess of 40 dB. See the paragraph 3.3.5.2 for installation procedures.
1.4.5 Outdoor Enclosure Unit)
The outdoor enclosure configuration is a ruggedized equivalent of an indoor enclosure
without the HCU, used for installation in uncontrolled environments. The enclosure
accommodates a network interface unit, HIC, an RFIA (timing reference source), a
+24VDC power supply (optional), and a heating/cooling unit. All modules in the enclosure
are either rack mountable or mounted on 19-inch trays. The maximum footprint of the
pedestal is 24 x 26 inches. The maximum height of the cabinet is 45 inches (including lift
brackets). The enclosure conforms to NEMA 3R requirements.

2.4 POWER REQUIREMENTS
Both the indoor and outdoor enclosures require external 110/220 VAC, single phase, 50/60
Hz with use of power supply and HCU, or +24 VDC for prime power.
2.4.1 Typical Prime Power Requirements
When both 110/220 VAC, single phase, 50/60 Hz and +24 VDC are available at the
installation site, an enclosure with 3 HICs/HFIs installed requires approximately 8
amperes of +24 VDC power. The HCU requires approximately 2.0 amperes of 110 VAC,
50/60 Hz (or approximately 1.0 ampere of 220 VAC, 50/60 Hz), single phase power.
2.4.2 Protective Earth Grounding
The Hub Equipment Enclosures must be properly grounded to protect installers and
operators from electrical shock. For this purpose there are two-1/4 in. x 20 ground studs
located on the left and right rear of the enclosure floor panel. These studs are used to
ground the internal components to the enclosure and to connect the enclosure 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 one of the ground stud by means of a properly sized ring
terminal. The enclosure is supplied with a split washer and a 1/4-in. x 20 nut to secure the
grounding cable ring terminal to the stud.
2.5 HUB EQUIPMENT CONFIGURATION AND SPACE REQUIREMENTS
2.5.1 Suggested Floor Space Requirements
Figure 2-1 shows the suggested floor space to support the Indoor Hub Equipment enclosure
installation, operator workspace, and service area.
2.5.2 Floor Loading Requirements
In order to safely support the weight of a fully loaded enclosure unit, the floor of the
installation site must be rated for a load of 150 pounds per square foot or more .
2.5.3 Typical Enclosure Configuration
Figure 2-2 shows a typical enclosure configuration as it appears before installation of the
rack-mounted assemblies. The indoor enclosure configurations use the same enclosures
and are stackable up to three high. Each individual enclosure is 24 inches high, 25 inches
deep, and 20 inches wide (outside dimensions). A minimum of 36 inches of clear space
behind the enclosure is recommended for servicing and proper ventilation. The HCU
contains an extendable keyboard tray, which adds another 36 inches of clearance

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 chance of overexposure to RF emissions when working near a
CMI, maintain a minimum distance of 12 in. from the transmitting antenna.
3.3.1 CMI Access
3.3.1.1 Opening the Assembly
WARNING
The CMI hinged cover (roadside) 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 a 1/2-inch socket wrench. Open the cover
carefully, keeping in mind that the cover (roadside) portion contains the Power Supply and
therefore is heavy.
3.3.1.2 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
internal wiring is clear of the housing seal. Torque the eight captive bolts to 140–145 in-lb
in the sequence shown in Figure 3-3.

There is Coaxial CMI configurations uses either a housing-to-F adapter or a housing-to-
hardline connector (shown in Figure 3-4). One or both ports are used, based on installation
requirements. The housing-to-F adapter or the housing-to-hardline connector is threaded
into the CMI housing, with its center conductor secured and connected to the internal CMI
circuits by a seizure screw. The procedure for cutting the center conductor to proper length
is shown in Figure 3-5. The seizure screw is accessed by removing a threaded plug located
at the rear of the CMI chassis (curbside). The seizure screw is tightened using a medium

The coaxial CMI configuration uses the FWD/REV port for the RF signal interface. The
other ALT/FWD port is used to supply source power to the unit (110/220VAC).
If the installation requirements dictate the use of housing-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 75-ohms coax and housing-to-hard-line adapter to CMI is
determined by mechanical constraints. Figure 3-6 shows an exploded view of these items.
The housing-to-hard-line adapter must be threaded into the CMI housing; therefore, it
must be separate from the 75-ohms coax during installation or removal. The seizure screw
is tightened against the housing-to-hard-line adapter center conductor after the adapter is
installed. The 75-ohms coax is joined to the housing-to-hard-line adapter after the adapter
is secured to the CMI. The adapter must be torqued to 30 in-lb.

3.3.2.2 Power Extractor Options
This document uses the terms single interface mode (also referred to as the combined
interface mode) in describing how the CMI is interfaced to the 75 Ohms coaxial network.
These terms are further defined as follows:
The CMI Power Extractor module is available in the configuration, as defined below:
♦ Single Interface Mode with frequency ranges as follows:
• Basic Frequency Range or Sub-Split - 5 to 42 MHz
• Extended Frequency Range or Mid-Split - 5 to 52 MHz1
The Power Extractor module is shown in Figure 3-7. The outward appearance of the two
configurations are identical except for the serial number. The eighth digit from the left of
the serial number is always 1 for the single interface mode (basic frequency range)
configuration; always 2 for the single interface mode (extended frequency range)
configuration. (The seventh digit from the left of the Power Extractor serial number is
always 2). For example, serial number 989T00210000 indicates a single (combined)
interface mode (basic frequency range) configuration.
The Power Extractor accommodates field-replaceable, plug-in attenuator pads for both the
forward and reverse coaxial paths, and a field-replaceable, plug-in equalizer in the forward
coaxial path (typically, the equalizer is set to 0dB). 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-0 to PP-10 attenuator pads or equivalents and Scientific Atlanta
model number EQ750 equalizers or equivalents. For typical installations, either
configuration of the Power Extractor will meet the requirements.
1 With this Power Extractor configuration, no other forward link services are allowed below 150 MHz.

3.3.3 Coaxial or Fiber Network Interface to the CMI
A coaxial network typically connects to the CMI through a 75 Ohms tap or coupler. The
tap or coupler is selected by the required loss between the Hub and the CMI at that
location.
A fiber network typically connects to the CMI in a similar manner as a coaxial network.
The fiber drop is coupled in to the network via a fiber splice. The operational range of the
fiber CMI (10 to 20 dBo; Hub to/from CMI) determines the coupled value required. The
fiber passes through the CMI housing via a Gilbert connector (PN NS7270-n; 1,5,9,or 11) or
equivalent.
3.3.4 Power Extractor Reverse Link/Forward Link RF Attenuation (Coaxial Installation)
The Power Extractor plugs into the CMI chassis and Connector Plate. It is secured by one
captive screw. As shown in Figure 3-7, the Power Extractor contains two plug-in
attenuator pad receptacles, one for adding reverse link attenuation and one for adding
forward link attenuation. It also includes a plug-in equalizer receptacle for forward path
equalization.
The Power Extractor is shipped with no pads or equalizer installed. It is recommended that
both attenuation and equalization values be initially set to 0 dB. The pad receptacles will
accept Scientific Atlanta model numbers PP-0 to PP-10 attenuator pads or equivalent. The
changing of pad values is discussed as part of the installation adjustments in paragraphs
3.5. The equalizer receptacle will accept Scientific Atlanta model number EQ750 equalizers
or equivalent. (Pads and equalizers may be provided by Transcept at the initial
installation, at customer request.)

SECTION 4.
BTS INTERFACE AND NETWORK OPTIMIZATION
4 BTS INTERFACE AND NETWORK OPTIMIZATION
4.1 INTRODUCTION
The purpose of this section is to configure a CDMA PCS Base Transceiver Station (BTS) to
operate a group of Cable Microcell Integrators (CMIs) in simulcast. The BTS may or may
not operate a conventional tower configuration in simulcast with the CMI simulcast sector.
The CMI distributed antenna system allows a PCS provider to connect multiple
transceivers to a single sector of a BTS. To allow this, the BTS must be configured to
compensate for the additional delay induced by the transport medium between
transmitters. The BTS has several tools in place to accomplish this, and when configured
properly, the distributed antenna system will be transparent to the network in terms of
timing delay.
If the BTS is to simulcast a conventional tower antenna (macrocell) with a number of
CMIs, the impact to the link budgets of both macrocell and CMIs must be assessed.
4.2 MEASUREMENT/CALCULATION OF CMI DELAYS
Base stations that process PCS calls through TransCell 1900CB equipment require
nonstandard settings due to additional delay in the forward and reverse links. More
specifically, the delay results from the addition of a CMI, a Hub Interface Converter (HIC)
and a coaxial, fiber, or HFC network in the RF path.
For the following four applications, the time delay (that is, coaxial/fiber lengths) between
the forward and reverse links must be determined. The induced delay is either equal or
unequal depending on the coaxial/fiber distances in the forward and reverse paths. The
CMIs involved can be on multiple fiber nodes and/or coax with passive splitters/combiners.
The applicable BTS settings are on a sector basis for each case:
a. Sector dedicated to TransCell 1900CB - Timing equal
b. Sector dedication to TransCell 1900CB - Timing unequal
c. Sector for TransCell 1900CB simulcasting with tower - TransCell 1900CB timing
equal
d. Sector for TransCell 1900CB simulcasting with tower - TransCell 1900CB timing
unequal
4.2.1 Sector Dedicated to TransCell 1900CB - Timing Equal
4.2.1.1 Description
The architecture in Figure 4-1 shows three sectors of a BTS dedicated to TransCell
1900CB. The HFC physical layer for the forward and reverse links is either shared or
parallel and has the same delay times from the BTS to the CMI antenna.

Figure 4-1. Sector Dedicated to TransCell 1900CB with Equal Timing Links
The delay added by the CMI and the HIC is the same for the forward link as it is for the
reverse link. Since timing is equalized on the network and TransCell 1900CB equipment,
and all PCS communications to the wireless handset are conducted through the CMIs, the
BTS does not have to account for any differential timing on the forward and reverse links
other than that internal to itself.
4.2.1.2 Basic BTS Settings for Dedicated Sector with Equal Timing
For the dedicated sector with equal timing, two TIA/EIA-95-B settings must be taken into
account, time reference and search window size. The BTS sets the search window in which
the mobile unit searches for usable multipath components of the set of appropriate pilot
signals. The following procedures are recommended for determining the setting of these
two parameters.
Regarding the time reference, section 6.1.5.1 of TIA/EIA-95-B states that the personal
station time reference “…shall be within ± 1 µs of the time of occurrence of the earliest
multipath component being used…” This establishes a common reference for system time
when searching for multiple BTS pilot signals.
For a dedicated sector implementation of TransCell 1900CB, the earliest multipath
component in the reverse link would typically appear at the antenna of the CMI that has
the least amount of delay to the base station. To determine which CMI this is, the delay
between each CMI antenna and the BTS input must be determined, either by measuring or
calculating the delay to each CMI antenna. The delay calculation or measurement is made
in a single direction if the timing in the dedicated sector implementation is equal in either
direction. To calculate the delay to a CMI antenna, the following formula is employed:
DTOTAL = DCMI/HIC + DFIBER + DCOAX + DLINE AMP [1]
TransCell 1900CB Installation Manual Document No. 1000070A
4-3
TRANSCEPT PROPRIETARY - DATA ON THIS PAGE SUBJECT TO RESTRICTIONS CITED ON COVER AND TITLE PAGE
where: DCMI/HIC is the group delay in one direction of the CMI and the HIC = 12 µs
DFIBER is the fiber delay at 5 µs/km of fiber (2.04 x 108 m/s). Actual value can be
obtained from fiber/cable specification sheets. It will be slightly different for the
different types of fiber or coaxial cable.
DCOAX is the coaxial delay at 3.8 µs/km (2.74 x 108 m/s). Actual value can be
obtained from fiber/cable specification sheets. It will be slightly different for the
different types of fiber or coaxial cable.
DLINE AMP is the delay added by all the line amps = 10 ns x no. of line amps
(actual value can be obtained from amplifier manufacturer or specification
sheets)
Once all the calculations have been made, the lowest delay value is then used for the time
reference setting on the BTS. This will move 0-system time out to the CMI antenna that is
nearest timewise. The calculated or measured value should be added to the default value
for both “Tx_offset” and Rx_offset”.
NOTE
For the time reference calculation, DAIR is 0 for a handset within 25 feet of the
nearest (timewise) CMI antenna.
The second setting that must be adjusted for TransCell 1900CB is the search window size.
This again is caused by the delay inherent with TransCell 1900CB. The settings affect the
active search window, the neighbor search window, and the remainder search window, if
active. Section 6.6.6.2.1 of TIA/EIA-95-B defines the establishment of search windows and
details the available base station settings and the resultant window sizes. TIA/EIA-95-B
states that: “The search window size for each pilot in the Active Set and the Candidate Set
shall be the number of PN chips specified in Table 6.6.6.2.1-1 with the window centered
around the earliest arriving multipath component of the pilot.”
The window size determines the number of chips off of center that the handset searches
when looking for PN offsets (set of pilot signals). This should be sized according to the
expected delay. The same holds true for the neighbor list and the remainder list. Table 4-1
lists the window size settings in Table 6.6.6.2.1-1 of TIA/EIA-95-B along with the
equivalent delay length.
For the dedicated sector with equal timing, the search window setting is selected from
Table 4-1 after calculating, with Equation [1] above, the delay for both the most delayed
CMI and the least delayed CMI in the sector and calculating the differential. This then is
the range through which the search window must repeatedly pass to pick up all CMIs in
the sector. Equation [2] determines the search window size. The search window is centered
on the CMI antenna that is nearest timewise. This calculation is made with a maximum
over-air propagation delay of 5.1 µs (1.5 km) to the most delayed CMI and a minimum over-
air delay of 0 µs to the least delayed CMI (the CMI whose nearest antenna is 0 system time
set point). Hence the search window size is calculated as shown in Equation [2] in terms of
µs and Table 4-1 determines the setting.

4.2.2 Sector Dedicated to TransCell 1900CB - Timing Unequal
4.2.2.1 Description
This architecture, shown in Figure 4-2, is similar to that shown in Figure 4-1 except that
the forward and reverse paths have different timing. As with section 4.2.1, the BTS sectors
are dedicated to CMIs. Although three sectors are shown, one or two sectors can be
dedicated to TransCell 1900CB with the remainder dedicated to towers. The CMIs can be
on multiple fiber nodes. The HFC physical layer for forward and reverse links is neither
shared nor parallel and has different delay times from BTS to CMI antenna. Since timing
is not equal on the HFC network and all PCS communications to the wireless handset are
conducted through the CMIs, the BTS has to account for the differential timing between
the forward and reverse links on the TransCell 1900CB physical layer. This can be
accomplished through either search windows or differential timing settings. Both are
discussed in the following paragraphs.

4.2.2.2 Basic BTS Settings for Dedicated Sector with Unequal Timing
For the dedicated sector with unequal timing, the two basic TIA/EIA-95-B settings already
discussed—time reference and search window size—must be taken into account, and
possibly differential timing as well. The following procedures are recommended for
determining the setting of the two basic parameters.
Time reference is calculated in the same manner as it was in section 4.2.1.2, except that it
is established by determining the delay along both links to each CMI and comparing them.
The delay calculations are made in each direction utilizing Equation [1]. The time reference
is determined by taking the delay that is the smallest and represents the nearest CMI
timewise. The forward path timing delay (Equation [1]) should be added to the default
setting for “Tx_offset”. The reverse path time reference should be added to the default
setting for “Rx_offset”.
The search window size is set in the same manner as it was in section 4.2.1.2. Equation [2]
is used to determine the search window size in µs based on the longest delay path and the
shortest delay path regardless of which link they are on. The shortest delay path is also at
the CMI whose nearest antenna is 0 system time set point. These two values are calculated
with Equation [1]. Table 4-1 is then referred to for the setting once the window size is
determined.

4.2.3 Simulcasting with a Tower - Timing Equal Within TransCell 1900CB
4.2.3.1 Description
This architecture, shown in Figure 4-3, is similar to that shown in Figure 4-1 except that
the BTS interface is through a coupled port. The RF for the alpha sector is split between
TransCell 1900CB and the tower antenna. This is a tower-CMI simulcast and can be done
on all three sectors, although Figure 4-3 shows it only for the alpha sector. The HFC
physical layer for forward and reverse links is either shared or parallel and has the same
delay times from BTS to CMI antenna.
Timing between links is equalized on the HFC network and TransCell 1900CB equipment
but not with the tower antenna. There will be a significant delay to the CMI because of the
HFC network and TransCell 1900CB group delay. PCS communications to the wireless
handset on the alpha sector can be through either the CMIs or the tower, and they can
hand off to each other. In handing off from the tower to the CMI, the BTS would regard the
CMI signal as a delayed multipath. To discriminate signals from the CMI to the tower, the
BTS would regard the tower signal as an advanced multipath.
4.2.3.2 Basic BTS Settings for Shared Sector with Equal Timing
For the shared sector, two basic TIA/EIA-95-B settings must be taken into account as in
the previous cases, time reference and search window size. The following procedures are
recommended for determining the setting of the two basic parameters.
Time reference is determined at the tower antenna, not the CMI, and assumes that tower
antenna distance from the BTS is less than the distance to the first CMI. This avoids
negative time and meets the TIA/EIA-95-B standard definitions for absolute time. The
delay is calculated from Equation [1] using only the DCOAX term, which defines the delay
over the heliax that runs from the BTS to the tower antenna.

The search window size is set in the manner similar to that in paragraph 4.2.1.2 except
that the window is centered around the absolute time at the tower antenna where the time
reference is set. Equation [2] is used to determine the search window size in µs based on
the longest delay path out to the furthest CMI (calculated with Equation [1]) and the
shortest delay path at the time reference antenna (0 second delay). Table 4-1 is then
referred to for the setting once the window size is determined.
It should be noted in this situation that the search window will be opened up more than it
would be for the tower alone. Thus in an established network, where the search windows
have been set prior to the addition of TransCell 1900CB, the search window sizing of
adjacent sectors that can hand off to the CMIs must be reset. The neighbor search windows
for these sectors must be set at the same value as the active search window for the sector
that contains the CMIs since the same delay rationale applies whether it is a handoff
across sectors or within a sector.
4.2.4 Split Sector - Timing Unequal Within TransCell 1900CB
4.2.4.1 Description
This architecture, shown in Figure 4-4, is similar to that shown in Figure 4-2 except that
the BTS interface is through a coupled port. The RF for the sector is split between
TransCell 1900CB and the tower antenna. This is a tower-CMI simulcast and can be done
on all three sectors, although Figure 4-3 shows it only for the alpha sector. The HFC
physical layer for forward and reverse links is neither shared nor parallel and has different
delay times from BTS to different CMI antenna. This is not the case with the tower, which
will have identical timing on the forward and reverse links. Also, as in section 4.2.3, there
will be a significant delay to the CMI as compared to the tower because of the HFC
network and TransCell 1900CB group delay. PCS communications to the wireless handset
on the alpha sector can be through either the CMIs or the tower and they can handoff to
each other. As in section 4.2.3, handing off in either direction is not a problem with the
proper time reference and window settings.

For the shared sector, two basic TIA/EIA-95-B settings must be taken into account as in
the previous cases, time reference and search window size. The following procedures are
recommended for determining the setting of the two basic parameters.
As in section 4.2.3, time reference is determined at the tower antenna, not the CMI. The

over the heliax which runs from the base station to the tower antenna.
The search window size is set in the manner similar to that in section 4.2.1.2 except that
the window is centered around the absolute time at the tower antenna where the time
reference is set, and calculations must be made for both the forward and reverse link of all
CMIs. Equation [2] is used to determine the search window size in µs based on the longest
delay path out to the furthest CMI (calculated with Equation [1]) and the shortest delay
path at the time reference antenna (0 second delay). Table 4-1 is then referred to for the

4.3 ASSESSMENT OF BTS SECTORS
Prior to connecting any TransCell 1900CB equipment to the BTS, verify that the applicable
BTS sector has been acceptance tested to the customer’s satisfaction. Also, if the CMIs are
to be simulcast with a macrocell tower antenna, the link budgets of the CMIs and the
macrocell must account for additional degradation in sensitivity and the resulting impact
to the RF footprints of both the tower and the attached CMIs. The BTS coverage tests
should be constructed to adequately address this issue.
All of the RF signal parameters are with respect to a single carrier. If total power is
measured (ie., via a power meter), the user is required to correlate the measurements to a
single carrier (ie., a single carrier is 4.75dB less than a three carrier signal).
4.4 PHYSICAL INTERFACES WITH BTS
The following are recommended procedures for interconnecting the HICs with the BTS and
the Hub.
NOTE
The cables needed for a full enclosure occupy much 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 space use.
In order to complete the following HIC integration procedure, network
technician on-site support is required.
The procedures that follow provide the initial checks and adjustments needed to
integrate an installed (acquired) HIC with the BTS in both Forward and Reverse
directions.
is provided for reference for the Forward link level check, and Figure 4-7 for the Reverse
link level check.
Cross-reference tables for PCS channel number-to-frequency and HIC channel number-to-
frequency are provided in Appendix B and Appendix C, respectively.
a. At HUB CONTROL PANEL: SUPER-USER dialog, double-click on desired installed

NOTE
The CMI data sheet at the end of this manual may be reproduced and used
for recording the measured levels specified in the following procedures.
4.4.1 Measurement of HIC Reverse Link Output
This procedure assumes that the reverse link from the network has been tested with active
CMIs per paragraphs 2.8.1.
a. For sector to be measured, disconnect RFIA BTS OUT PRI/DIV output cables from
RFIA (if applicable).
b. Disconnect HIC Input cable for sector to be measured (if applicable).
c. Using a 75Ω cable, connect a signal generator to HIC input port of sector to be
measured. Set signal generator as follows with RF output DISABLED:
• Frequency: CMI reverse link Primary (or Diversity) pedestal center frequency
for the sector being measured.
• If measuring RFIA/HIC REV Primary BTS output, set the signal generator to
CMI REV Primary pedestal center frequency; if measuring RFIA/HIC REV
Diversity BTS output, set to the CMI REV Diversity pedestal center frequency.
• RF Output Power Level: -39 dBm Connect spectrum analyzer to HIC BTS OUT
PRI/DIV output terminals using 50 Ω connectors, and set spectrum analyzer as
follows:
• Center Frequency: REV PCS CDMA Channel (Chan. 150 = 1857.5 MHz)
• Scale: 2 dB/div
• Span: 6 MHz
• RBW: 1.25 MHz (or 30 kHz)

d. Enable RF output of signal generator to inject CW signal into HIC CATV IN port.
e. Determine if reverse link output level of CW signal is between -50 and -60 dBm.
Adjust reverse link attenuator of HIC until the CW signal is -55 dBm ± 1 dB.
4.4.1.1 HIC CDMA Reverse Link Output to BTS
NOTE
This procedure assumes all connections between the HIC and the network
have been made and the external equipment, RF signals, and
communications are functioning properly.
The Reverse output power of the HIC is -50 to -60 dBm (nominal of -55 dBm)
with –93 dBm injected at CMI receive ports. Depending on cable length and
Reverse BTS input power level specification, external attenuator pads may be
necessary for optimal performance.
The RFIA/HIC provides the CDMA Reverse link input signals to the BTS. Each HIC
provides a pair of reverse link signals for each sector, designated PRI (Primary) and DIV
(Diversity).
a. Connect an RF cable to alpha sector reverse link Primary (Rx - S1D0) input port of
BTS, and route cable to selected RFIA/HIC in the Hub enclosure.
b. Secure cable to appropriate cable troughs to eliminate any strain on cable
connectors.
c. Verify that both reverse RFIA/HIC output levels (primary and diversity) are within
specification in accordance with paragraph 4.4.1.
d. Connect cable to REV alpha BTS OUT PRI port on rear panel of selected RFIA.
(Figure 4-10).
e. Connect an RF cable to alpha sector reverse link Diversity (Rx - S1D1) input port of
BTS, and route cable to selected RFIA/HIC.
f. Connect cable to REV alpha BTS OUT DIV port on rear panel of selected RFIA.
g. Repeat steps a through f for beta sector of RFIA/HIC and BTS, connecting to S2D0
and S2D1 ports on BTS.
h. Repeat steps a through f for gamma sector of RFIA/HIC and BTS, connecting to
S3D0 and S3D1 ports on BTS.

4.4.2 CDMA Forward Link Input from BTS
The BTS provides the CDMA forward link input signal to the installed RFIA/HICs. Each
installed RFIA/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. The following procedure is used to
measure the HIC forward link CDMA Input Power level after interfacing with the BTS.
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 alpha sector (S1) forward link CDMA output
port of BTS, and route cable over to vicinity of selected RFIA/HIC in the Hub
enclosure. Do not connect cable at this time.
b. Secure cable to appropriate cable troughs to eliminate any strain on cable
connectors.
c. For sector to be measured, connect HIC forward link CDMA input cable (after
RFIA) from BTS to spectrum analyzer input (50 Ω).
d. Set spectrum analyzer as follows:
• Center Frequency: FWD PCS Channel Frequency
(PCS Ch. 25 = 1931.25 MHz)
• Span: 6 MHz; 1.25 MHz (or 30 kHz RBW)
• Scale: 2 dB/div
• Input Impedance: 50 Ω
• Units: dBm
• Video Averaging: 100 Averages

Maximum +5.0 dBm -2.0 dBm
Minimum -2.0 dBm -9.0 dBm
Single CDMA Carrier, 30 kHz RBW

Maximum -12.7 dBm -19.7 dBm
Minimum -19.7 dBm -26.7 dBm
f. Record measured level.
g. After level has been verified, connect Forward link cable between RFIA alpha
sector and FWD alpha BTS IN port on rear panel of selected HIC (Figure 4-10).
h. Repeat steps a through g for beta and gamma sectors to complete one
RFIA/HIC/BTS connection. (The BTS beta sector is S2 and the gamma sector is
S3.)
4.4.3 CDMA Forward Link Output to Coaxial Network
The HIC provides the CDMA Forward link signal to the coaxial network or fiber network
through the HFI. Each HIC provides a single forward link signal (one or three carriers),
the combined output of all three sectors.
a. Connect a forward link RF or Fiber cable from appropriate forward link device in
Hub; route cable to selected HIC or HFI in Hub enclosure.
b. Secure cable to appropriate cable troughs to eliminate any strain on cable
connectors.
c. Connect coaxial cable to FWD CATV OUT port on rear panel of selected HIC for a
coaxial installation (Figure 4-10) or connect the fiber cable to the appropriate HFI
transceiver port.

4.4.3.1 HIC Forward Link CDMA Pilot Level
This procedure verifies that the CDMA Pilot Level at the HIC FWD CATV OUT port is
between -26 and -36 dBm.
NOTE
CDMA levels should be measured in a 1.23-MHz resolution bandwidth.
However, a 30-kHz RBW can be used by adding a 16.1-dB correction factor to
the measured level in order to obtain the actual level.
(16:1 = 10LOG 1.23 MHz/30 kHz)
a. Connect a spectrum analyzer to HIC FORWARD TEST POINT (75 Ω).
b. Set spectrum analyzer as follows:
• Center Frequency: FWD HIC Channel
• Scale: 2 dB/div
• Span: 6 MHz
• RBW: 1.25 MHz (or 30 kHz)
c. Adjust span and/or center frequency so that forward CDMA pedestals for all sectors
can be seen.
d. Measure HIC forward CDMA output at HIC FORWARD TEST POINT with
spectrum analyzer, using display line and 100 averages. Determine if forward link
CDMA power levels are within range:
Single CDMA Carrier, 1.25 MHz RBW
65% Pole Pilot Only
Maximum -19 dBm -26 dBm
Minimum -29 dBm -36 dBm
Single CDMA Carrier, 30 kHz RBW

Maximum -35 dBm -42 dBm
Minimum -45 dBm -52 dBm
e. Adjust attenuation as needed in HIC FORWARD POWER dialog (Figure 4-12) to

4.5 INITIAL SETTING OF BTS PARAMETERS
4.5.1 Initial Conditions
a. The BTS should be installed and connected to the RFIA/ HIC.
b. The CDMA power levels should be set in both directions throughout the TransCell
1900CB system to meet nominal operating conditions.
c. The link budgets associated with the RF footprint of each CMI and macro sector (if
simulcasting with CMIs) should have been evaluated prior to CW testing. The bases
for the link budgets will be verified with the fine-tuning of the BTS parameters
(paragraph 4.6).
4.5.2 Guidelines for Initial Setting of Parameters
The delay to each CMI should be measured/calculated as described in paragraph 4.2. This
measurement/calculation will be used only as a means of establishing an initial phone call
over the TransCell 1900CB system; the actual delay will be measured later.
The forward delay value should be added to the manufacturer’s default forward delay (BTS
hardware delay) in the Tx_offset_fine parameter. The reverse path delay estimate will be
incorporated into the Rx_offset_fine parameter by adding the estimate to the manufac-
turer’s default value. Note that these values may be in either decimal or hexadecimal
depending on the BTS manufacturer. Typically, the values will be entered in units of 1/8
PN chip (approximately 101.75 ns).
The BTS uses a parameter called the access time-out to determine how long to wait for a
given phone to respond to a paging message when originating calls. This parameter may
need to be increased for use with a TransCell 1900CB sector. The parameter to be changed
is called ACC_TMO and defines the access time-out by the equation:
TA = (2 + ACC_TMO) * 80 ms
Typically, an increase of 2 or 3 units will be sufficient. A larger increase can be used
initially, then stepped down later during system optimization.
At this point it should be possible to place a call at the nearest CMI location using the CMI
transport system in both directions. A mobile diagnostic monitor can be used to verify that
the forward link signal is using the CMI path, rather than an “over-air” path from a
distant tower. In the reverse direction, the CMI receivers can be disabled to verify which
CMI path is being utilized.
Once it is confirmed that the call is using the CMI transport path in both directions, a call
trace should be initiated on the given test phone and used to monitor a phone call for
several seconds. The switch log of the call trace will record round trip delay from the
channel cards in the BTS through the mobile unit. This value will be used to refine the
earlier delay estimates.
The round-trip delay divided by 2 will yield a preliminary one-way delay. (Note: It is very
important that the physical transport path be identical in both directions. If this is not the
case, then a BTS correction factor is needed to compensate for BTS propagation delay
differences in the two directions. (i.e., Tx_Delay offset, Rx_Delay offset).

A-3 EQUIPMENT DESCRIPTION
The RF Interface Assembly (RFIA) provides an interface between the HIC, BTS, HFI, and
Coaxial Network. It also generates a stable 15-MHz reference signal to the HICs installed
in the indoor enclosure and the outdoor enclosure.
The RF Interface Plate Assembly (see Figure C-1) serves as a transition point within the
Hub equipment enclosure to convert the larger and more rigid cabling from the BTS and
coaxial network to smaller and more flexible cabling to the HIC. One RFIA is required for
each HIC installed. This configuration is mounted in the rear of the enclosure directly
above the associated HIC and occupies space the size of one HIC.
This panel provides the interface between the HIC (“TNC” connectors), the BTS (“N”
connectors) and the coaxial network or the HFI (“F” connectors). There are nine type N
connectors that interface the signals for the three sectors from the BTS to the HIC and four
type F connectors that interface the reverse IF signals and the forward IF signal for all
three sectors to the HIC. A 15 MHz oscillator on the assembly provides a reference
frequency for the HIC.

Figure C-1. RF Interface Plate Assembly
The RFIA configurations provide duplexing of the RF signals between the HIC, the BTS
and the coaxial network or HFI. When necessary, amplifiers may be inserted to increase
the power levels of the signals between the HIC and BTS.
A duplexer is used to permit coupling of transmit and receive signals through a single port.
This device is used primarily for those installations that require the interfacing a single
BTS sector to a single HIC, or two or three sectors of a BTS to a single HIC.
One RFIA is required for each HIC installed. Each RFIA requires +24 VDC for operation.
