The information in this document guides you through configuring an ADC®
FlexWave® Prism system through its web-based Element Management System
(EMS) Release 7.1. The EMS is an embedded software application that runs on the
Host and that may be accessed via an internet connection using a web browser.
CAUTION!The instructions in this document assume that you have already installed the FlexWave
Prism units as described in their respective installation guides (see Table 1).
The Preface describes how to use the FlexWave Prism user documentation.
ADC’s FlexWave® Prism is a compact radio head utilized for precision and macro
gap coverage, which supports up to four frequency bands, while delivering
high-performance coverage with end-to-end management. FlexWave Prism is
ideal for enhancing outdoor and indoor coverage in urban, suburban, canyons,
tunnels, campuses, stadiums and other public venues.
A Prism system offers the following features:
•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.
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.
A very basic Prism system consists of a Host Unit (Host) and a Prism Remote Unit
(PRU).
•The Host is a three rack unit high chassis with multiple cards that mounts in a
standard equipment rack.
•The PRU 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 such as a passive Wavelength Division
Multiplexer (WDM) system and a Coarse Wavelength Division Multiplexer (CWDM)
system are available as accessories.
Control and monitoring functions are provided by the FlexWave Element
Management System (EMS).

Figure 5. System Block Diagram for Eight-Way Simulcast
In a FlexWave Prism system, each BTS provides the RF channel inputs and outputs
for a designated sector. Each Host may be interfaced with one or more Base
Transceiver Station (BTS).
On the forward path, the Host receives Analog RF signals from the BTS, digitizes
the designated RF bands, and then transports them over single-mode fiber to up
to 8 Remote Units. The Remote Unit(s) receives the digitized spectrum from the
Host and converts the spectrum back into an analog RF signal to be distributed via
an externally mounted antenna system.
On the reverse path, the Remote Unit digitizes the designated RF spectrum and
digitally transports it over single mode fiber or Millimeter Wave (MMW) to the
Host. The Host receives the digitized RF signals from the Remote Unit and converts
them back to Analog RF for the BTS.
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 path optical
signal and a second fiber is used to transport the reverse path optical signal.
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 6.

Figure 6. Standard Fiber Optic Transport Application
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 dB (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.
NOTE:The RF modulation used determines the maximum fiber length between the Host and
Remote units, which is dependent on how much delay that modulation type will handle.

Prism System Overview
HOST UNIT OVERVIEW
The rack-mountable Host is typically located with the RF source—a Base
Transceiver Station (BTS). The Host is DC powered and supports up to eight BTS
interfaces through DART (Digital/Analog Radio Transceiver) cards. (For further
information on DART Modules, see
The Host is designed for use within a non-condensing indoor environment, such
as inside a base-station shelter, Central Office, wiring closet, or a
controlled-environment cabinet. It is installed into a 19- or 23-inch, rack-mounted
chassis, that is 9-inches deep and can hold up to three units. All controls,
connectors, and indicators, except for the grounding point, are accessible on front
of the Host.

Prism System Overview
Serialized RF (SeRF) Digital Protocol
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 (single fiber pair).
The available RF bandwidth per timeslot is shown in Table 5.

For example, a user who wishes to transport PCS A block, Cellular A, and AWS B
block, the system would require the following:
Simulcast combining occurs when more than one Remote DART is linked to the
same Host DART. The gains of the reverse signals are reduced before summation
to prevent over-flow when the digital signals are added together. This simulcast
gain reduction is accomplished as a function of the number of Remote DARTs
linked to the Host DART (N) and the selected Reverse Gain Mode:
•Mode 1 (Noise Floor Matching)—uses an algorithm that normalizes the noise floor of
all Remote Units.
•Mode 2 (Legacy Prism/URH)—reduces the gain by 20*log10(N).
•Mode 1 (Noise Floor Matching) uses an algorithm that normalizes the noise floor
of all Remote Units.
•Mode 2 (Legacy Prism/URH)—reduces the gain by 20*log10(N).
Table 6 illustrates gain reduction for Mode 1 and Mode 2.

Reduction (dB)
Mode 1 Mode 2
Simulcast groups are restricted to using the same timeslots on the fibers to each
Remote. For example, if the first link established in a simulcast group is using
timeslots 1-3 on a fiber for the PCS A passband, timeslots 1-3 must be used for
that passband on each of the other Remotes in the simulcast group. If timeslots
1-3 are not available on a Remote's fiber, the Remote cannot be added to the
simulcast group.
To minimize timeslot conflicts, simulcast groups should be configured before other
passbands. If a conflict occurs while attempting to link a DART, an error message
displays indicating that the DART linking failed. The DART using the conflicting
timeslots must be unlinked to allow the DART in the simulcast group to be linked.

Prism System Overview
Use of Multi Fibers
The EMS provides the ability to install “multi fibers” between a Host and Remote.
This means that, in addition to the minimum single fiber pair (RX and TX) in the
Host to Remote connection, one or more additional fiber pairs are installed. This
is done to increase the bandwidth or number of timeslots between the Host and
Remote.
Each fiber pair can handle approximately 75 MHz of RF bandwidth and each fiber
is capable of supporting 12 timeslots, as described in
When a Host DART is linked to a Remote DART in a multi-fibers configuration, the
EMS uses the first fiber (in numerical order) on which the required number of
timeslots is available for the passband being linked. The EMS will not divide up the
timeslots between two fibers. So, for example, if the passband requires eight
timeslots, and only six timeslots are available on the first fiber, the EMS will bypass
the first fiber and assign all eight timeslots to the second fiber, leaving four
timeslots unused on the second fiber.
The DART type determines the maximum number of links, where there can be up
up to 8 Classic DARTs or Single SuperDARTs that support 35MHz each, or up to 4
Dual SuperDARTs that support up to 75MHz each.
E911 support may be achieved by using a configuration similar to the one shown
Figure 14. Remote simulcasting in this configuration requires analog splitting
in
and combining to and from the individual Host DARTs. External analog
splitting/combining ensures that the E911 system receives uplink signals from
each Remote location before they are combined with uplink signals from the other
Remotes in the simulcast.

Unit Identification
Figure 17 shows the Unit ID in the System Tree. The Unit ID is the hostname
(user-defined label) plus the layer address. The layered address is H-R, so the Unit
ID is <hostname>H-R, where:
•H—Host # is always 1
•R—Remote Unit # (PRU or URU), which can be 1 - 8 and is based on the SFP
You can view any parameter or alarm by navigating to the page in which the
parameter or alarm resides. To quickly find information about a parameter or
alarm:
•All parameters are listed alphabetically in this manual’s Index.
•All alarms are listed alphabetically in this manual’s Index of Alarms.
•All traps are listed alphabetically in this manual’s Index of Traps.
Alarm Color Codes
Alarms are color coded in the GUI according to the level of the alarm:
•Green—No alarm
•Blue—Information alarm, which provides information on a successful user
action, such as a change in a forward or reverse delay setting
•Yellow—Minor alarm
•Red—Major alarm
•Gray—the alarm has been disabled; see “Enable and Disable Host and Remote
Unit Alarms” on page 178
•White—a device has not been installed. For example, in Figure 18, which shows
the Unit Information > View Status page, the Module Status table shows that a DART
has not been installed in slots 3, 7, or 8. The Optical Status table shows that SFPs
are not installed in Optical ports 2 through 8.
