This section provides a basic description and application and configuration
information about the FlexWave Prism system. Throughout this publication, all items
referenced as “accessory items” are not furnished with the basic product and must
be purchased separately.
ADC’s FlexWave™ Prism is a compact radio head for macro gap coverage that
supports up to four frequency bands delivering high-performance coverage with
end-to-end management.
The FlexWave Prism enhances wireless networks in outdoor locations and large
venues in an easy and cost-effective manner. Based on patented technology and
ADC’s 15-year leadership in outdoor wireless distributed antenna system (DAS)
technology, FlexWave Prism offers mobile operators a small, light, and flexible
solution for extending macro network coverage for 2G, 3G, and 4G services.
The new FlexWave Prism system is ideal for enhancing outdoor and indoor coverage
in cities, suburbs, canyons, tunnels, campuses, stadiums, and other public areas. It is
35 percent lighter and up to 60 percent smaller than the FlexWave URH product it
replaces, and is available in four different cabinet sizes to support one, two, three or
four frequency bands. Operators can future-proof their deployments by purchasing
a larger cabinet and adding more frequency bands when needed. FlexWave Prism uses
ADC’s proven radio head technology and management system along with an IP-65
rated remote.
1.1.1Product Features
••Management under the same host end equipment and EMS as the FlexWave URH,
allowing operators to scale legacy URH deployments with the FlexWave Prism
••ADC’s patented RF-over-fiber transport eliminates installation-dependent gain or
fiber length adjustments
••Improved manageability for installation and upgrades
••Smaller size to ease placement and zoning approvals
••4G readiness with Four Band remote, which is ideal for incorporating 2G and 3G
services with needs of 4G technologies such as LTE
••The unique capability to support digital RF as well as baseband compatibility into
a single fiber pair and remote radiating point
••Support for millimeter wave backhaul
••With its unique use of wideband digital RF transport, FlexWave Prism delivers
reliable and consistent performance in all environments. Signals are not affected
by reflection, dispersion, or frequency attenuation over fiber. FlexWave Prism
delivers a reliable signal at every remote location.
A very basic Prism system consists of a Host Unit (Host) and a Remote Unit (Remote):
••The Host is a three rack unit high chassis with multiple cards that mounts in a
standard equipment rack.
••The Remote consists of multiple electronic and optical modules mounted in an
outdoor enclosure.
On an optional basis, the Prism system supports reverse path diversity. In addition,
various accessory items including a passive Wavelength Division Multiplexer (WDM)
system, Coarse Wavelength Division Multiplexer (CWDM) system, and expansion
panels are available as accessories.
Control and monitoring functions are provided by the FlexWave Element
Management System (EMS).
Some examples of FlexWave Prism Systems are shown in Figure 1-1, Figure 1-2,
ADC’s FlexWave Prism provides a Multi-Host feature that allows a Prism Remote to be
shared by multiple Host Units. To accomplish this:
••One Host is designated as the IP Manager for a set of Remotes; this Host can serve
as IP manager for multiple Remotes. As the IP Manager, the managing Host
controls the exchange of management data with the Remote(s).
••There is no Host to Host connectivity.
••A Prism Remote can receive bands over multiple fibers that originate on different
Hosts. However, only one Host, the IP Manager, can manage the Remote. If a Host
attempts to manage a Remote already under the management of an IP Manager,
the second Host causes an IP Conflict fault (see “Viewing Host SeRF Optical Ports”
on page 224).
••All the Hosts in a Multi-Host network can be configured to serve as clock master.
Each Host will be configured with a priority level in the range of

DARTs are linked back to one or more Hosts in a Multi-Host system.
Digital/Analog Radio Transceiver (DART) cards provide the interface between base
station equipment and the SeRF. There are three types of FlexWave DART cards:
••Classic
••Single SuperDART
••Dual SuperDART.

In a typical Prism system the Host is connected to the Remote using two single-mode
optical fibers. One fiber is used to transport the forward pathh optical signal and a
second fiber is used to transport the rev erse pathh optical signal. With the diversity
option, the div ersity rev erse pathh optical signal is sent on the same reverse path
fiber. (However, the diversity signal can also be transmitted on a separate fiber pair
if more than 12 timeslots are required at a single Remote.) Because the optical signal
is digital, the input and output RF signal levels at the Host or the Remote are not
dependent on the level of the optical signal or the length of the optical fiber. A
diagram of the standard fiber optic transport system for both a non-diversity and
diversity system is shown in Figure 1-9.
The maximum length of the optical links is dependent on the loss specifications of
the optical fiber and the losses imposed by the various connectors and splices. The
system provides an optical budget of 25 dBB (typical) when used with 9/125
single-mode fiber. There must be at least 10 dB of optical loss to prevent over-driving
and possible damage to the optical receiver.

Figure 1-9. Standard Fiber Optic Transport Application
The SeRF (Serialized RF) digital protocol consists of digitized RF, Fast Ethernet, and
Host to Remote communication and management. The protocol provides you with
full access to the 100BASE-T (Ethernet) connection between the Host and each
Remote, and the ability to provision the RF spectrum of the DARTs. The digitized RF
portion of the SeRF protocol is divided into 12 timeslots, with each timeslot
representing roughly 5 MHz of digitized RF spectrum. Utilizing the full 12 timeslots
yields between 60 and 75 MHz of total digitized RF on each SeRF Small Form-Factor
Pluggable (SFP) laser connection.
Ea ch fiber p air supports 12 timeslots, or up to 75 MHz of bandwidth. Table 1-2 shows
the maximum bandwidth versus the number of timeslots.
If more than 70 MHz is required per Remote, up to three additional fiber pairs can be
brought to the Remote to get up to up to 280MHz per Remote (or 300MHz if all four
are GSM-1800). This supports applications where there are two Classic DARTs or
Single SuperDARTs or one Dual SuperDART in a Remote RF Module.
The SeRF (Serialized RF) digital protocol consists of digitized RF, 100BASE-T Ethernet,
and Host to Remote communication and management. The protocol provides you
with full access to the 100BASE-T Ethernet connection between the Host and each
Remote, and the ability to provision the RF spectrum of the DARTs. The digitized RF
portion of the SeRF protocol is divided into 12 timeslots, with each timeslot
representing roughly 5 MHz of digitized RF spectrum. Utilizing the full 12 timeslots
yields between 60 and 80 MHz of total digitized RF on each SeRF SFP laser connection.
In the FlexWave Prism system, there are different Bandwidths from which to select,
ranging from 5 to 75 MHz. The different bandwidths allow you to configure the
system to use any contiguous or non-contiguous blocks within the 35 MHz of a single
Host 6-timeslot DART or 60-75 MHz using a 12-timeslot DART. DART bandwidth
options are shown in Table 1-3.
For DART cards, if you need to use non-contiguous blocks within a given 35 MHz,
then the selected bandwidth must span both of these blocks, even if the blocks in
between are not used. For example, if you want to use both PCS DD and EE blocks, select
the BB block is effectively unused.
PCS D and E are only 10 MHz of spectrum, four timeslots are required since the actual
transported spe
, which spans 25 MHz. This allows both PCS DD & EE to be transported and
ctrum is 25 MHz for the PCS D, B, E block, as shown in Table 1-3.
The Dual-AWS and Dual-PCS DARTs allow you to span non-contiguous bands:
••the Dual-AWS DART comprises two 6-Timeslot AWS DARTs that span the full 45
MHz of the AWS band
••the Dual-PCS DART provides two PCS blocks over the entire 70 MHz PCS
spectrum.
In the forward path, the two Remote DARTs are summed together before being sent
to the Linear Power Amplifier (LPA). In the reverse direction, the Low Noise Amplifier
(LNA) is split providing the full PCS or AWS spectrum to each DART. Each DART is
responsible for transporting its own spectrum, as shown in an the following example
for a PCS configuration.
If the application requires both the A and C block, in the Remote the forward path of
the PCS A band is combined with the forward path of the PCS C band and these
signals are sent to the LPA to be amplified. In the reverse direction, the Duplexer/LNA
passes/amplifies the entire PCS band. The first DART digitizes the PCS A block
reverse path and the second DART digitizes the PCS C block reverse path and then
sends them back to the Host to be reconstructed back into RF.
The installer needs to provide the separate connections at the Host location either by
splitting already combined signals to/from each DART, or by providing them
independently.
If the tw o PCS reverse path blocks are combined at the Host location, then they must be
separated by
other during the re- combin
at least 5 MHz to insure that the reverse paths do not interfere with each
The ADC FlexWave Prism family of products is a Distributed Antenna System (DAS)
that provides ADC’s patented technology—bidirectional transport of digitized RF
spectrum over fiber. The high-speed digitalization of a wideband portion of spectrum
allows for transport of RF signals over extended distances, without the RF
degradation that normally results when analog systems are impacted by optical
effects. The basic function of the FlexWave Prism platform is to transport via fiber
optic cable RF signals from a Base Transceiver Station (BTS) to an antenna interface
allowing communication to a mobile device. Multiple BTS communication paths are
allowed over a single Prism system. Each link consists of a Host that provides the
interface between the base station RF ports and the optical fiber, and at least one
Remote that provides the interface between the optical fiber and the remote antenna.
A block diagram of the system is shown in Figure 2-1.
The basic function of FlexWave Prism simulcast (point-to-multipoint) is to transport,
via fiber optic cable, RF signals from a Base Transceiver Station (BTS) to multiple
antenna interfaces allowing communication to a mobile device (see Figure 2-2). Up to
8 simulcast Remotes are supported.

Figure 2-2. System Block Diagram for Eight-Way Simulcast
The Host is designed for maximum RF flexibility to address Carriers’ changing and
evolving spectrum needs, making the most use of cost efficient resources for serving
multiple remotes such as simulcast architecture and sharing of common functions
such as power, control and management over multiple Hosts. Each Host may be
interfaced with one or more Base Transceiver Station (BTS). Each BTS provides the RF
channel inputs and outputs for a designated sector.
The Host is designed as a compact package that reduces rack space required within
a BTS Hotel. The Host is a three rack-unit high single-unit assembly that mounts in a
standard 19- or 23-inch equipment rack. Its front access interfaces with the BTS for
transport to subtended Remotes, and performs the analog to digital and electrical to
optical conversions for transport to a Host and subtended Remotes. Each Host can
support up to eight Remotes. The Remote is a modular self-contained outdoor
enclosure that houses various electronic components.
2.2.1Host Front Panel.
The Host is designed for use within a non-condensing indoor environment such as
inside a wiring closet or controlled environment cabinet. All controls, connectors, and
indicators (except the grounding point) are mounted on the Host front panel and
allows vertical cable guides to be installed over the mounting brackets on either side.
The Host user interface on its front panel comprises the connectors, switches,
terminals, and LEDs that are described in Figure 2-3 and Table 2-1.
The Host can be mounted in either a 19- inch or 23- inch EIA or WECO equipment rack.
Unless noted other
brackets in the 23- inch position. The defa

2.2.2Host Network Connection
The SeRF front panel has a Network port that creates a network connection between
the Host and the network to monitor and configure the FlexWave Prism system
through the FlexWave EMS.
The network interface connection between the Host and the network is supported by
a Gigabit Ethernet (10/100/1000) RJ-45 jack with integrated green ACTIVITY and
LINK LEDs. The Network port supports a maximum cable length of 100 meters (328
feet) to a switch or back-to-back nodes. CAT5 or better cable should be used when
making this connection. The Ethernet connection should not be connected to an
Ethernet circuit used outside the building.
For further information on using the Network port and the FlexWave EMS, see
“System Setup and Management.”
2.2.3Host RF Signal Connections
The RF signal connections between the Host DART cards and the BTS are supported
through two (FWD RF IN and REV RF OUT) QMA-Type female connectors. One
connector is used for the forward path RF signal. The other connector is used for the
reverse path RF signal. In some installations, it may be necessary to install a
Conditioning Panel and/or Duplexing Panel (accessory items) to support the interface
between the Host and the BTS. The Host should be as close as possible to the BTS to
minimize cable losses.
The System Card contains the fan controller, the clocking circuitry (internal or
external), the temperature sensor and the DCC contacts. Its front panel provides
connections for alarm outputs, 10 MHz output, and status LEDs. This card may be
used to provide a 10 MHz clock reference to which the SeRF's Master clock is
frequency locked from the internal crystal oscillator. When the internal clock is not
used the clock can be obtained from an external 10 MHz input.
The Remote, shown in Figure 2-4, controls RF emissions, interfaces with the FlexWave
Host and performs the optical to electrical conversions for transport to the antennas.
The Remote is an environmentally-sealed unit that houses the electronic assemblies
such as the DART board and the Power Amplifier, and seals out dirt and moisture.
The Prism uses fans located on the top of each unit to cool the chassis. The antenna
cable connectors, fiber connectors, AC power connector, and the unit status indicator
are located on the bottom of the unit.
The FlexWave Remote supports or provides the following basic functions:
••Receives on the forward path the digitized spectrum from the Host and converts
the spectrum back into an RF signal to be distributed via an externally mounted
antenna system. On the reverse path, the Remote digitizes the designated RF
spectrum and digitally transports it over single mode fiber or Millimeter Wave
(MMW) to the Host.
••Provides RF interface (antenna port) for the antennas.
••Accepts AC power input.
2.3.1Handset Interface
The Remote interfaces with the handsets (cell phones) through an antenna. In the
reverse path, the Remote receives RF signals from each handset (see Figure 1-3 on
page 9). The Remote digitizes the RF signals and then converts them to digital optical
signals for transport to the Host over the optical fiber link. In the forward path, the
Remote receives digital optical signals from the Host. The Remote converts the
optical signals to RF signals for transmission to the handsets.
2.3.2Remote Components
Prism Remotes are shipped ready to accept easy to install RF Modules. The following
sections describe the Remote components listed below and shown in Figure 2-5.
The Remote has an internal Duplexer that is optimized to provide the desired RF
band-pass filtering and in-band equipment isolation between FWD and REV paths.
The Duplexer contains up to two REV path Low Noise Amplifiers (LNA for PRI and/or
SEC reverse paths). Each LNA (shown in Figure 2-8) is a high quality low noise
amplifier providing the Prism reverse path with nominal 30dB REV gain and system
NF of 5dB per RX path. The Duplexer and its LNA are housed in the RF Module, and
are not field servicable.

2.3.2.3Remote Power Supply and Cable Assembly
The Remote is powered by 100 to 240 VAC (nominal 120 or 240 VAC), 50 to 60 Hz
power. The AC power is supplied through a 15-foot (4.6m) three-wire power cable
that is provided with the unit. The power cable connects to a 3-pin AC power
connector mounted on the bottom of the Remote.
The stub end of the power cable must be routed to an external junction box (not
provided) for connection to the AC power source. A circuit breaker rated at 20 Amps
(120 VAC) should be used to provide over-current protection for the Prism power
circuit. It is also recommended that an external AC outlet (not provided) be installed
near the Remote to power test equipment and tools.
The Remote model determines the number of power supplies.
••The Single-Band Remote is powered by one power supply.
••The Dual-Band Remote is powered by two power supplies.
••The Tri- and Quad-Band Remotes are powered by three power supplies.
There are up to four switches that independently control DC power for each RF
Module. These switches are labeled MOD A, MOD B, MOD C, and MOD D and
correspond to the RF Module shelves, from bottom to top, that are labeled the same.

lice it. Do not use a splicer that uses light to align the cores.
2.3.2.8Remote Antenna Cable Connections
The TX0/RX0 antenna cable connections are through 50-ohm N-type female
connectors. The Remote includes an internal Duplexer which allows a single antenna
cable to carry both forward and reverse path RF signals between the antenna and the
Remote. The RX1 diversity antenna cable connections are through 50-ohm N-type
female connectors.
2.3.2.9Remote Grounding
A double-ground stud and ring lug is supplied with the unit. A #6 copper wire
terminated with the provided ring terminal must be provided to link the Remote to
an earth ground source.
For proper and safe equipment operation, an approved earth ground connection must
be provided. The re
commended minimum w ire size is #6 AWG copper wire.
2.3.2.10 Remote Cooling
The electronic compartment of the Prism is sealed to the environment. Prism
conducts its heat to a rear heat sink and the front doors. Two external
environmentally hardened fans are controlled and monitored by the system. When
turned on, these fans pull air over the external surfaces of the enclosure to ensure
the electronics run within their rated temperature. The fans run at three different
speeds depending on the internal temperature of the system. An alarm is generated
if a high temperature condition occurs within the enclosure.
The maximum ambient operating temp is 50°C (122°F).
This section provides a brief description of various accessory items that are available
separately. The accessory items may or may not be required depending on the
application.
An externally-mounted lightning surge suppressor is available separately as an
accessory for the Remote. To reduce the chance of damage to electronic components
should a lightning strike occur, install a lightning surge suppressor at each antenna
port that connects to an outdoor antenna. The surge/antenna connector on the
lightning suppressor is an N-type female connector. The Prism Remote Unit must be
properly grounded for the lighting surge suppressor to function properly.
2.4.2Uninterruptible Power Supply (Accessory)
Any power interruption without an external Uninterruptible Power Supply (UPS)
system will potentially result in an RF power outage. If a UPS is required it should be
designed into the site plan during the engineering process.
2.4.3Wavelength Division Multiplexer System
(Accessory)
In some applications, it may be desirable or necessary to combine the forward path
and reverse path optical signals from a single Host/Remote pair onto a single optical
fiber. This can be accomplished by using a passive bi-directional Wavelength Division
Multiplexer (WDM) system. The optical wavelengths used in the Prism system are
1550 nm for the forward path and 1310 nm for the reverse path. Because different
wavelengths are used for the forward and reverse paths, both signals can be
combined on a single optical fiber. A WDM application is shown in Figure 2-15.
The WDM Host module mounting shelf and Host module are shown in Figure 2-16.
The WDM module is shown in Figure 2-17. WDMs at the Remote are in the fiber patch
cord and placed in the enclosure.

2.4.4Course Wavelength Division Multiplexer System
(Accessory)
Prism Coarse Wavelength Division Multiplexer (CWDM) systems are pre-configured
with the correct wavelength SFPs installed as well as the correct wavelength OADM
module. SFPs installed in the Host provides the following optical wavelengths:
The Host is connected to a CWDM chassis that contains the CWDM Mux/DeMux Units
that multiplex the wavelengths from the transceivers onto a single fiber in the
Forward path and de-multiplexes the wavelengths from the Remotes into their
respective wavelengths. The Remote within a CWDM system requires an internal
Prism CWDM Fiber Cable Assembly. Figure 2-18 on Page 52 shows the CWDM
Mux/DeMux unit and Figure 2-19 shows the CWDM Fiber Cable Assembly. For further
information on the Prism CWDM system, see the ADC FlexWave™ Prism Coarse Wavelength Division Multiplexer User Manual (ADCP-75-353).

A Millimeter Wave (MMW) system with a data rate of not less than 3 Gbps (that meets
the FlexWave Prism data rate performance and BER requirements) may be used in
applications where it is desirable or necessary to bridge an open span and where it is
impractical to lay a fiber optic cable. One MMW transceiver unit may be mounted on
the Host side of the open span and the other MMW transceiver unit may be mounted
on the Remote side of the open span. A system diagram of an MMW application is
shown in Figure 2-22. MMW systems are available from various equipment
manufacturers.

A mmw link (3GBps) is required for 12 timeslots worth of RF traffic between the Host
and the Remote. This is roughly 60 - 75MHz depending on the modulation. If a
Remote has more bandwidth requirements (such as 210MHz of RF), there would need
to be 3 point-to-point mmw links.
This section provides the installation procedures for the Host and the WDM Host
module (accessory item). Installation of the Remote components may proceed
separately from installation of the Host.
This chapter guides you through installing a Prism Host, which requires 70 steps that
are divided into 11 sections. Follow the steps in the order in which they are provided.
3.3.1Unpacking and Inspection
This section provides instructions for opening the shipping boxes, verifying that all
parts have been received, and verifying that no shipping damage has occurred.
11Inspect the exterior of the shipping container(s) for evidence of rough handling
that may have damaged the components in the container.
22Unpack each container while carefully checking the contents for damage and
verify with the packing slip.
33If damage is found or parts are missing, file a claim with the commercial carrier
and notify ADC Customer Service (see “Contacting ADC” on page 335). Save the
damaged cartons for inspection by the carrier.
44Save all shipping containers for use if the equipment requires shipment at a
future date.
3.3.2Install Host in Equipment Rack
A pair of reversible mounting brackets is provided that allow the Host to be mounted
in either a 19-inch or 23-inch EIA or WECO equipment rack. When installed, the Host
front panel is flush with the front of the rack.

Use the following procedure to install the Host in the equipment rack:
55The Host is shipped with the mounting brackets installed for 19-inch rack
installations. If mounting the Host in a 19-inch rack, proceed to Step 6. If
mounting the Host in a 23-inch rack, proceed to Step 8.
66Remove both mounting brackets from the Host (requires TORX screwdriver with
T20 bit) and save screws (six-screws on each side) for reuse.
77Reinstall both mounting brackets so the long side of the bracket is flush with the
Host front panel as shown below. Use the screws removed in Step 6 to re-attach
the brackets to the Host chassis.

88Position the Host in the designated mounting space in the rack (per system design
plan) and then secure (but do not tighten) the Host to the rack using the four
machine screws provided (use #12-24 or M6 x 10 screws, whichever is
appropriate).
99Locate two vertical cable guides, not provided with the Host.
A v ertical cable guide kit is available separately as an accessory.
100 Back out the Host mounting screws just enough to provide clearance for
installation of the cable guides.
111 Slide each cable guide into position for installation and then securely tighten the
The outside plant (OSP) fiber optic cables should be routed between the Host
distribution panel and Remote outside plant cabinet and terminated before the
equipment is installed. A diagram of a typical OSP cable routing is shown in
Figure 3-1. At the Host, the OSP cable should be terminated at a fiber distribution
panel and spliced to fiber patch cords. Jumper patch cords may then be used to link
the Host optical ports to the OSP cable terminations. Whenever possible, a guideway
such as the FiberGuide system should be provided to protect the fiber optic patch
cords from damage and to prevent excessive bending. The procedures for connecting
the OSP cable optical fibers to the Host is provided in “Optical Connections Without
WDM System” on page 74. and “Optical Connections For Systems With a WDM” on
page 76.

The RF interface between the Host DART card and the EBTS/BTS is supported through
two type QMA female connectors mounted on each DART front panel. One connector
provides the coaxial cable connection for the forward path (downlink) signal and the
other connector provides the coaxial cable connection for the reverse path (uplink)
signal.
In most installations, it is usually necessary to insert an external attenuator into the
forward path link between the Host and the BTS. Before completing the forward path
connection at the BTS, verify that the composite forward path RF signal level at the
Host is between –25 and +5 dBm.
The Host should be mounted as close as possible to the EBTS/BTS to minimize cable
losses. Use the following procedure to route and connect the forward and reverse
path coaxial cables to the Host DART cards:
177 Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial
communications cable (RG-400 or equivalent) for all coaxial connections.
188 Route the forward and reverse path coaxial cables between the Host and the BTS
interface (per system design plan) and cut to the required length. Allow sufficient
slack for dressing and organizing cables at the Host and for installing an external
attenuator in the forward path link.
199 Terminate each cable with a QMA-Type male connector following the connector
supplier’s recommendations.
200 If required, install an external attenuator in the forward path.
The composite forward path RF signal lev el at the Host must be between –25 and + 5
dBm. Do not connect

211 Connect the forward and reverse path cables as shown in the following graphic.
aaConnect the forward path cable to the FWD RF IN connector on the Host DART
front panel.
bbConnect the reverse path cable to the REV RF OUT connector on the Host DART
Optical connections between the Host SeRF card and the Remote are supported
through Small Form-Factor Pluggable (SFP) transceivers. The optical interfaces are
standard single-mode duplex LC (flat polished UPC). One SFP comes with the
Host—additional SFPs (up to 7) must be ordered separately as needed.
There are two fiber connections—one FWD and one REV—for each SFP. As the SeRF
holds up to eight SFPs, there is a total of 16 connections: eight FWD and eight REV.
The FWD path is 1550nm (from the Host to the Remote) and the REV path is 1310nm
(from the Remote to the Host).
Each FWD port provides an optical connection for the forward path (downlink) signal.
Each REV port provide an optical connection for the reverse path (uplink) signal. Each
REV port can also provide the optical connection for the diversity reverse path
(uplink) signal.
The optical connections are dependent on whether or not a WDM Host module
(accessory) is installed:
••If the installation does not include a WDM module, proceed to Section 2.9.2 for
the optical connections procedure.
••If the installation includes a WDM module, proceed to Section 2.10 for the optical
connections procedure.

••Overdrive: >-9dBm
••Underdrive: <-27dBm
••RX No Light condition: <-34dBm
The receiver’s specification is -9 to -27dBm. Based on typical fiber runs, there's
usually only a few dB of loss, so the 15dB LC attenuator (Figure 3-2) ships with each
Host to put the receive level in the optimum receive range.

3.3.10System Alarm Connections
The alarm interface between the Host and an alarm system is supported by
twelve-terminal plug (with screw-type terminals) that connects to a receptacle
mounted on the Host System card front panel. The terminal plug provides
connections to normally open (NO) and normally closed (NC) dry type alarm contacts
for both major and minor alarms. A category 3 or 5 cable is typically used to connect
the Host System card to the alarm system.
577 Connect the Minor alarm wire pair to the MINOR COM/NC or MINOR COM/NO
terminals (whichever is required by the alarm system) on the Host System card
alarm terminal connector (as shown above and in Table 3-1).
588 Connect the Major and Minor alarm wire pairs to the appropriate terminals on the
external alarm system.
599 Dress and secure cable per standard industry practice.
3.3.11Power Connections
The Host has a modular DC to DC power supply located on the lower left side of the
chassis, which is secured by turning its screws clock-wise until tight.
An On/Off switch is provided on the Host power supply module front panel
(Figure 3-3).
Figure 3-3. Host Power Connector
The Host is powered by ± 20 to ± 60 Vdc power (nominal ± 24 or ± 48 Vdc), which is
fed to the Host through a connector located on the front of the module. Power to the
Host must be supplied through a fuse panel (available separately). Each Host must be
protected with a fuse.
A three position terminal block is provided for connecting the power wires. The
power is fed to the Host Power Supply module through the Power Connector located
on the Host front panel (Figure 3-3). Power to the Host must be supplied through a
fuse panel such as the 20 position PowerWorx GMT Fuse Panel (available separately)
and the power must be protected with an appropriate GMT fuse:
