SECTION 2 InterReach™ Unison System
Description
2.1 System Overview
InterReach™ Unison is an intelligent fiber optic wireless networking system that is
designed to handle both wireless voice and data communications and provide
high-quality, ubiquitous, seamless access to the Cellular or Personal Communications
Services (PCS) network in any public or private facility, including:
• Campus environments
•Airports
• Office buildings
• Shopping Malls
• Hospitals
• Public Facilities (convention centers, sports venues, etc.)
Unlike other wireless distribution alternatives, Unison is an intelligent active system,
using microprocessors to enable key capabilities such as software-selectable band set-
tings, automatic gain control, ability to incrementally adjust downlink/uplink gain,
end-to-end alarming of all components and the associated cable infrastructure, and a
host of additional capabilities.
The Unison system supports major Cellular/PCS standards and air interface protocols
in use around the world, including:
• Frequencies: 800 MHz, 900 MHz, 1800 MHz, 1900 MHz, 2100 MHz
• Protocols: AMPS, TDMA, CDMA, DCS, GSM, EGSM, iDEN, CDPD, EDGE,
GPRS, WCDMA

Key System Features
•Superior RF performance, particularly in the areas of IP3 and noise figure.
•High downlink composite power (+26 dBm), IP3 (+38 dBm) and low uplink
noise figure (22 dB for a system with 8 RAUs), enables support of a large number
of channels and larger coverage footprint per antenna.
• The Main Hub and the Expansion Hub are software configurable. Thus, the fre-
quency band can be field configured.
• The system supports flexible cabling alternatives, allowing the use of either mul-
timode or single-mode fiber (in addition to standard Cat-5 or Cat-6 [Cat-5/6]
twisted pair). Cabling type can be selected to meet the resident cabling infrastruc-
ture of the facility and unique building topologies.
•Extended system “reach”. Using multimode fiber, fiber runs can be as long as
1.5 kilometers. Alternately, with single mode fiber the fiber run can be as long as
6 kilometers (creating a total system “wingspan” of 12 kilometers). And the
Cat-5/6 twisted pair cable run can be up to 100 meters recommended maximum
(150 meters with RF performance degradation).
•Flexible RF configuration capabilities, including:
• System gain:
– Ability to manually set gain in 1 dB steps on both downlink and uplink.
• RAU:
– RAU uplink and downlink gain can be attenuated 10 dB.
– Uplink level control protects the system from input overload and can be
optimized for either a single operator or multi-operators/protocols.
– VSWR check on RAU reports if there is a problem with the antenna.
• The system firmware effectively “future proofs” the product. When any modi-
fications are made to the product, including the addition of new software capabili-
ties/services, systems that have already been installed can be upgraded simply by
downloading new firmware (either locally or remotely).
•Extensive OA&M capabilities, including fault isolation to the field replaceable
unit, automatic reporting of all warnings and alarms, and user-friendly graphi-
cal-user interface OA&M software packages.

PRELIMINARY System Hardware
2.2 System Hardware
The InterReach Unison system consists of three modular components:
• 19" rack-mountable Main Hub (connects to up to 4 Expansion Hubs)
• Converts RF signals to optical on the downlink; optical to RF on the uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Software configurable band
• Simplex interface to any RF source
• System master – periodically polls all downstream units (Expansion
Hubs/RAUs) for system status, and automatically reports any warnings/alarms
• 19" rack-mountable Expansion Hub (connects to up to 8 Remote Access Units)
• Converts optical signals to electrical on the downlink and electrical signals to
optical on the uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Software configurable band (based on command from Main Hub)
• Supplies DC power to RAU
•Remote Access Unit (RAU)
• Converts electrical signals to RF on the downlink; RF to electrical on the
uplink
• Microprocessor controlled (for alarms, monitoring, and control)
• Protocol/band specific units
The minimum configuration of a Unison system is one Main Hub, one Expansion
Hub, and one RAU (1-1-1). The maximum configuration of a system is one Main
Hub, four Expansion Hubs, and 32 RAUs (1-4-32). Multiple systems can be com-
bined to provide larger configurations.

2.3 System OA&M Capabilities
The InterReach Unison is microprocessor controlled and contains firmware which
enables much of the OA&M functionality.
Complete alarming, down to the field replaceable unit (i.e., Main Hub, Expansion
Hub, Remote Access Unit) and the cabling infrastructure, is available. All events
occurring in a system, defined as a Main Hub and all of its associated Expansion
Hubs and Remote Access Units, are automatically reported to the Main Hub. The
Main Hub monitors system status and communicates that status using the following
methods:
• Normally closed (NC) alarm contact closures can be tied to standard NC alarm
monitoring systems or directly to a base station for alarm monitoring.
• The Main Hub’s front panel serial port connects directly to a PC (for local access)
or to a modem (for remote access).

PRELIMINARY OA&M Software
2.3.1 OA&M Software
The AdminManager software runs on a Laptop PC which is either directly connected
to the DB-9 RS-232 male connector on the Main Hub’s front panel or is remotely
communicating through a modem that is connected to the DB-9 connector on the
Main Hub’s rear panel. The AdminManager communicates with one Main Hub, and
its downstream units, at a time.
• Connected locally, you can access the Installation Wizard which lets you configure
a newly installed system, or access the Configuration Panel which lets you query
system status, configure a newly added or swapped unit, or change system parame-
ters.
• Connected remotely, AdminManager initiates communications with the Main
Hub. You can access a read-only Configuration & Maintenance panel which lets
you check system status to help you determine if an on-site visit is required.
Refer to Section 7 for information about installing and using the AdminManager soft-
ware.
Alternately, an LGC Wireless OA&M software application called the OpsConsole is
available separately. The OpsConsole lets you manage, monitor, and maintain multi-
ple sites and systems from a centralized location. This software is described in the
OpsConsole User Guide, LGC Wireless part number 8701-10.
2.3.2 Configuring, Maintaining, and Monitoring Unison Locally
Each Main Hub, Expansion Hub, and RAU in the system constantly monitors itself
and its downstream units for internal fault and warning conditions. The results of the
monitoring are stored in memory and compared against new results.
The Expansion Hubs monitor their RAUs and store their status in memory. The Main
Hub monitors its Expansion Hubs and stores their status and the status of the RAUs in
its memory. When a unit detects a change in status, a fault or warning is reported.
Faults are indicated locally by red status LEDs, and faults and warnings are reported
to the Main Hub and displayed on a PC/laptop, via the Main Hub’s serial port, that is
running the AdminManager software.
Using AdminManager locally, you can install a new system or new components,
change system parameters, and query system status. The following figure illustrates
how the system reports its status to AdminManager.

PRELIMINARY Monitoring and Maintaining Unison Remotely
2.3.3 Monitoring and Maintaining Unison Remotely
• Using AdminManager Remotely
You can use AdminManager to query Unison status via a read-only Configuration
& Maintenance panel. You cannot change system parameters or configure system
components remotely with AdminManager. (Refer to Figure 2-1 on page 2-4.)
• Using OpsConsole Remotely
When monitoring the system remotely, any change of state within the system
causes the Main Hub to initiate an automatic call-out and report the system status
to the OpsConsole. If the host does not acknowledge the connection, the Main Hub
issues an automatic call-out every 15 minutes until an auto acknowledge or stan-
dard request for status (initiated by the host) is received.
Refer to the OpsConsole User Guide, LGC Wireless part number 8701-10, for
more information about using the OpsConsole for system monitoring.
The following figure illustrates how the system reports its status to AdminManager
and the OpsConsole.
Figure 2-3 Remote System Monitoring and Reporting
Expansion
Hub
The Expansion Hub checks its own status
and polls each of its RAUs for their status.
Each RAU reports its status to
the Expansion Hub.
• If a fault is detected, the
ALARM LED is red. If no fault
is detected, the LED is green.
• If a fault or warning condition
is detected, the information is
passed to the Expansion
Hub.
The Expansion Hub
receives status from
each RAU and compares
it to previously stored status.
• If a fault is detected, LEDs on
the front panel light red.
• If a fault or warning condition
is detected in the Expansion
Hub or an RAU, the informa-
tion is passed to the Main
Hub.
The Main Hub receives
status of Expansion Hub
and each RAU and com-
pares it to previously
stored status.
• If a fault is detected,
LEDs on the front panel
light red.
• If a fault or warning con-
dition is detected in any
unit, the Main Hub ini-
tiates a call to the
OpsConsole.
Use the OpsConsole to
remotely monitor and
maintain multiple systems.
OpsConsole sends an
email and/or page notifica-
tion when a change in sys-
tem status is detected.
Use AdminManager to
query status of a single

of its downstream units)
and determine if a site visit
is required.

PRELIMINARY System Connectivity
2.4 System Connectivity
The double star architecture of the Unison system, illustrated in the following figure,
provides excellent system scalability and reliability. The system requires only one
pair of fiber for 8 antenna points. This makes any system expansion, such as adding
an extra antenna for additional coverage, potentially as easy as pulling an extra
twisted pair (instead of pulling additional fiber).

Unison Main Hub Unison Expansion Hub RAU
Downlink Path: The Main Hub receives downlink RF signals from a base station, repeater, or MetroReach Focus system
via coaxial cable. It converts the signals to optical and sends them to up to four Expansion Hubs via fiber optic cables.
The Main Hub also sends OA&M communication to the Expansion Hubs via the fiber optic cable. The Expansion Hubs, in
turn, communicate the OA&M information to the RAUs via Cat-5/6 cable.
Uplink Path: The Main Hub receives uplink optical signals from up to four Expansion Hubs via fiber optic cables. It converts
the signals to RF and sends them to a base station, repeater, or MetroReach Focus system via coaxial cable.

3.1.3 LED Indicators
The unit’s front panel LEDs indicate fault conditions and commanded or fault lockouts.
The LEDs do not indicate warnings or if the system test has not been performed. Use
the LEDs as a go/no go test or as a backup when you are not using AdminManager.
Upon power up, the Main Hub goes through a five-second test to check the LED
lamps. During this time, the LEDs blink through the states shown in Table 3-2, letting
you visually verify that the LED lamps and the firmware are functioning properly.
NOTE: Refer to Section 10 for troubleshooting using the LEDs.
Unit Status LEDs
The Main Hub status LEDs can be in one of three states, as shown in Table 3-1.
These LEDs can be:
steady green

Unison Expansion Hub
Unison Main Hub RAU
Downlink Path: The Expansion Hub receives downlink optical signals from the Main Hub via fiber optic cable. It converts
the signals to electrical and sends them to up to eight Remote Access Units (RAUs) via Cat-5/6 cables.
Also, the Expansion Hub receives configuration information from the Main Hub via the fiber optic cable and relays configu-
ration information to the RAUs via the Cat-5/6 cable.
Uplink Path: The Expansion Hub receives uplink IF signals from up to eight RAUs via Cat-5/6 cables. It converts the sig-
nals to optical and sends them to a Main Hub via fiber optic cable.
Also, the Expansion Hub receives RAU status information via the Cat-5/6 cable and sends it and its own status information
to the Main Hub via the fiber optic cable.

SECTION 6 Installing Unison Components
6.1 Installation Requirements
6.1.1 Component Location Requirements
Unison components are intended to be installed in indoor locations only.
6.1.2 Cable and Connector Requirements
The Unison equipment operates over standard Category 5 or 6 (Cat-5/6) screened
twisted pair (ScTP) and industry-standard single-mode fiber (SMF) or multimode
fiber (MMF) cable.
These cables are widely used industry standards for Local Area Networks (LANs).
The regulations and guidelines for Unison cable installation are identical to those
specified by the TIA/EIA 568-A standard and the TIA/EIA/IS-729 supplement for
LANs.
LGC Wireless recommends plenum-rated Cat-5/6 ScTP and fiber cable and connec-
tors for conformity to building codes and standards. ScTP is required in order to meet
FCC and CE Mark emissions requirements.
6.1.3 Neutral Host System Requirements
As in any Unison system, a neutral host system requires one pair of fiber strands
between each Main Hub and each Expansion Hub, and one Cat-5/6 cable between
each Expansion Hub and each RAU. To help achieve the cost savings possible in a
neutral host system, it is advantageous to install additional cables for future growth.

PRELIMINARY Safety Precautions
6.2 Safety Precautions
6.2.1 Installation Guidelines
Use the following guidelines when installing LGC Wireless equipment:
1. Provide sufficient airflow and cooling to the equipment to prevent heat build-up
from exceeding the maximum ambient air temperature specification. Do not com-
promise the amount of airflow required for safe operation of the equipment.
2. Be careful when servicing these products. If you are removing the system, turn it
off and remove the power cord first. There are no user-serviceable parts inside the
components.
3. The internal power supply has internal fuses that are not user replaceable. Con-
sider the worst-case power consumption shown on the product labels when provi-
sioning the equipment’s AC power source and distribution.
6.2.2 General Safety Precautions
The following precautions apply to LGC Wireless products:
• The units have no user-serviceable parts. Faulty or failed units are fully replaceable
through LGC Wireless. Please contact us at:
1-800-530-9960 (U.S. only)
+1-408-952-2400 (International)
+44(0) 1223 597812 (Europe)
• Although modeled after an Ethernet/LAN architecture and connectivity, the units
are not intended to connect to Ethernet data hubs, routers, cards, or other similar
data equipment.
• When you connect the fiber optic cable, take the same precaution as if installing
Ethernet network equipment. All optical fiber SC/APC connectors should be
cleaned according to the cable manufacturer’s instructions.
• When you connect a radiating antenna to an RAU, DO NOT over-tighten the SMA
connector. Firmly hand-tightening the connector is adequate.
WARNING: To reduce the risk of fire or electric shock, do not
expose this equipment to rain or moisture. The components are
intended for indoor use only. Do not install the RAU outdoors. Do not
connect an RAU to an antenna that is located outside where it could
be subject to lightning strikes, power crosses, or wind.

6.2.3 Fiber Port Safety Precautions
The following are suggested safety precautions for working with fiber ports. For
information about system compliance with safety standards, see Appendix C.
WARNING: Observe the following warning about viewing fiber
ends in ports. Do not stare with unprotected eyes at the connector
ends of the fibers or the ports of the hubs. Invisible infrared radia-
tion is present at the front panel of the Main Hub and the Expansion
Hub. Do not remove the fiber port dust caps unless the port is going to be used.
Do not stare directly into a fiber port.
•Test fiber cables: When you test fiber optic cables, connect the optical power
source last and disconnect it first. Use Class 1 test equipment.
•Fiber ends: Cover any unconnected fiber ends with an approved cap. Do not use
tape.
•Broken fiber cables: Do not stare with unprotected eyes at any broken ends of the
fibers. Laser light emitted from fiber sources can cause eye injury. Avoid contact
with broken fibers; they are sharp and can pierce the skin. Report any broken fiber
cables and have them replaced.
•Cleaning: Be sure the connectors are clean and free of dust or oils. Use only
approved methods for cleaning optical fiber connectors.
•Modifications: Do not make any unauthorized modifications to this fiber optic
system or associated equipment.
•Live work: Live work is permitted because LGC Wireless equipment is a Class 1
hazard.
•Signs: No warning signs are required.
•Class 1 laser product: The system meets the criteria for a Class 1 laser product
per IEC 60825-1:1998-01 and IEC 60825-2:2000-05.
•CAUTION: Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure.
This label appears on the front panel of the
Main Hub and the Expansion Hub.

Installing Passive Antennas
Refer to the manufacturer’s installation instructions to install passive antennas.
Passive antennas are usually installed below the ceiling. If they are installed above
the ceiling, the additional loss due to the ceiling material must be considered when
estimating the antenna coverage area.
Considerations:
• Use coaxial cable with the least amount of loss possible.
• Keep iDEN and 800 MHz cellular antennas at least 6 to 8 meters (20 to 26 ft)
apart.
Connecting the Antenna to the RAU
Connect a passive antenna to the SMA male connector on the RAU using coaxial
cable.
CAUTION:When connecting to the SMA female connector on
the RAU and passive antenna, DO NOT over-tighten the connec-
tor. Firmly hand-tightening the connector is adequate.

Powering On the Expansion Hub
1. Connect the AC power cord to the Expansion Hub.
2. Plug the power cord into an AC power outlet.
3. Turn on the power to the Expansion Hub and check that all the LED lamps are
functioning properly.
Upon power-up, the LEDs will blink for five seconds for a visual check that they
are functioning. After the five-second test:
•The
POWER and UL STATUS LEDs should be green.
•The
E-HUB STATUS and DL STATUS LEDs should be red because the Main Hub
is not yet connected.
• All port LEDs should be off because no RAUs are connected yet.
NOTE: Leave the dust caps on the fiber ports until you are ready to connect the fiber
optic cables.
Testing and Connecting the Fiber Cables
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
3 dB optical budget.
• If fiber distribution panels are used, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished).Using any
other connector type will result in degraded system performance and may damage
the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are
not SC/APC, see “Splicing Fiber and Pigtail” on page 6-18.)
NOTE: Observe all Fiber Port Safety Precautions listed in Section 6.2.3 on page 6-4.
To test the fiber cables:
1. Perform cable testing and record the results.
Test results are required for the final As-Built Document.
2. Make a note of which cable you will use for uplink and downlink.
This information is needed when connecting the cables to the Main Hub.

PRELIMINARY Installing Expansion Hubs
To clean the fiber ports:
Use compressed air to blow dust out of each fiber port before you insert the SC/APC
connector. Note that compressed air should not leave any residue as this will contam-
inate the fiber port.
To clean the fiber connectors:
Be sure that the fiber cable’s SC/APC connectors are clean and free of dust or oils. If
the fiber connector front face is not free of dust or oils, follow the manufacturer’s rec-
ommendations for cleaning it.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. In addition to these
labels, you should add a code that identifies which port on the Main Hub is being
used and which Expansion Hub the cables are intended for. This differentiates the
connectors for proper connection between the Main Hub and Expansion Hubs.
If the fiber jumper is labeled with 1 or 2:
1. Connect 1 to UPLINK on Expansion Hub.
2. Connect 2 to DOWNLINK on Expansion Hub.
3. Label both ends of each cable with which Main Hub port is used.
For example:
First pair to Main Hub port 1: 11 (uplink), 12 (downlink);
Second pair to Main Hub port 2: 21 (uplink), 22 (downlink);
Third pair to Main Hub port 3: 31 (uplink), 32 (downlink); and so on.
4. Record which number you connected to UPLINK and DOWNLINK.
This information is needed when connecting the other end of the fiber cable to the
Main Hub’s fiber ports.
If the fiber jumper is color-coded (for example, “blue” or “red”):
1. Connect “blue” to UPLINK on Expansion Hub.
2. Connect “red” to DOWNLINK on Expansion Hub.
3. Label both ends of each cable with which Main Hub port is used.
For example:
First pair to Main Hub port 1: 11 (uplink), 12 (downlink);
Second pair to Main Hub port 2: 21 (uplink), 22 (downlink);
Third pair to Main Hub port 3: 31 (uplink), 32 (downlink); and so on.
4. Record which color and port number you connected to UPLINK and DOWNLINK.
This information is needed when connecting the other end of the fiber cable to the
Main Hub’s fiber ports.

Splicing Fiber and Pigtail
The fiber cable must have SC/APC connectors. If it does not, you can splice a pigtail,
which has SC/APC connectors, to the fiber cable.
There are two different pigtails: 1 for single-mode fiber (PN 4013SCAPC-3) and 1
for multimode fiber (PN 4012SCAPC-3).
To splice the fiber optic cable to the SC/APC pigtail: Option A
1. Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed
immediately adjacent to the Hub.
2. Prepare the fiber end by ring-cutting the polyethylene jacket, cutting back the
Kevlar strands, and stripping back the fiber cladding.
Ensure that sufficient slack is maintained in order to be able to reach the fusion
splicer.
3. Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.
4. Cleave the unclad fiber to the length prescribed by the fusion splicer’s specifica-
tion sheets.
5. Repeat steps 2 through 4 for the SC/APC pigtail.
6. Pass the splice sleeve onto the fiber strand.
7. Position both fiber ends in the fusion splicer and complete splice in accordance
with the fusion splicer’s operation instructions.
8. Ensure that the estimated loss for the splice as measured by the fusion splicer is
0.10 dB or better.
9. Slide the fusion splicing sleeve over the point of the fusion splice.
10. Place the sleeve and fused fiber into the fusion splicer’s heater.
11. Allow time for the splice sleeve to cure.
12. Return fiber splice to the splice tray, store the sleeve in a splice holder within the
tray, and store excess cable length in accordance with the tray manufacture’s
directions.
After successfully testing the fiber, plug the SC/APC pigtail into the proper opti-
cal port on the Hub.

carrier(s) together, then the 800 MHz cellular carrier(s), and so on.
Connecting to base stations and repeaters is the same as described in Section 6.6 on
page 6-29 and Section 6.6.1 on page 6-33.

6.5 Starting and Configuring the System
Connecting a Laptop and Starting the AdminManager Software
Considerations:
• The AdminManager software is installed on a laptop computer that meets the
requirements that are listed on page 7-2.
• Null modem cable with female connectors is needed.
To connect the laptop and start the AdminManager software:
1. Connect the null modem cable to the laptop and then to the RS-232 port on the
Main Hub’s front panel.
2. Turn on the laptop and start the AdminManager software.
The main Installation Wizard window is displayed when the software is ready.
Powering On the Main Hub
After mounting the Main Hub in the rack, connect it to the AC power. You may use
multiple outlet surge protectors for multiple Main Hubs.
1. Connect the AC power cord to the Main Hub.
2. Plug the power cord into an AC power outlet.
3. Turn on the power.
Upon power-up, the LEDs will blink for five seconds for a visual check that they
are functioning. After the five-second test:
•The
POWER LED should be green.
•The
MAIN HUB STATUS LED should be red because a band has not been pro-
grammed.
• All fiber port LEDs should be off, indicating that no fiber cables are connected.
NOTE: Leave the dust caps on the fiber ports until you are ready to connect the fiber
optic cables.

PRELIMINARY Starting and Configuring the System
Connecting the Fiber Cables to the Main Hub
Considerations:
• Before connecting the fiber cables, confirm that their optical loss does not exceed
3 dB optical budget.
• If fiber distribution panels are used, confirm that the total optical loss of fiber
cable, from the Main Hub through distribution panels and patch cords to the
Expansion Hub, does not exceed the optical budget.
• Make sure the fiber cable’s connectors are SC/APC (angle-polished). Using any
other connector type will result in degraded system performance and may damage
the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are
not SC/APC, see “Splicing Fiber and Pigtail” on page 6-18.)
NOTE: Observe all Fiber Port Safety Precautions listed in Section 6.2.3 on page 6-4.
To clean the fiber ports:
Use compressed air to blow dust out of each fiber port before you insert the SC/APC
connector. Note that compressed air should not leave any residue as this will contam-
inate the fiber port.
To clean the fiber connectors:
Be sure that the fiber cable’s SC/APC connectors are clean and free of dust or oils. If
the fiber connector front face is not free of dust or oils, follow the manufacturer’s rec-
ommendations for cleaning it.
To connect the fiber cables:
The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection
between the Main Hub ports and the Expansion Hub ports, refer to the numbering or
color-coded connections you recorded when installing the Expansion Hub(s).
If the fiber jumper is labeled with 1 or 2:
1. Connect 1s to UPLINK ports on the Main Hub.
Refer to the connections you recorded, or the cable label, when the Expansion
Hub(s) were installed to know which Main Hub UPLINK port to use.
2. Connect 2s to DOWNLINK ports on the Main Hub.
Refer to the connections you recorded, or the cable label, when the Expansion
Hub(s) were installed to know which Main Hub DOWNLINK port to use.
If the fiber jumper is color-coded (for example, “blue” or “red”):
1. Connect “blue” to UPLINK ports on the Main Hub.
Refer to the connections you recorded, or the cable label, when the Expansion
Hub(s) were installed to know which Main Hub UPLINK port to use.
2. Connect “red” to DOWNLINK ports on the Main Hub.
Refer to the connections you recorded, or the cable label, when the Expansion
Hub(s) were installed to know which Main Hub DOWNLINK port to use.

Checking the Main Hub’s Fiber Port LEDs
•The LINK LED should be green if the fiber is connected to the Expansion Hub, and
communication and optical power are okay.
•The
E-HUB/RAU LED should be red because a band has not been programmed.
• If the LINK LED is red and the E-HUB/RAU LED is off, there is no communica-
tion with the Expansion Hub. Check the fiber cables (downlink first); a cable
may be broken or the optical link budget may be exceeded.
• If the PORT LEDs are blank (off), the Main Hub does not recognize the pres-
ence of an Expansion Hub. Check the fiber cables (uplink first); a cable may be
broken or the optical link budget may be exceeded. Check to ensure that the
cables are connected at the Expansion Hub, and that the Expansion Hub’s
power is on.
NOTE: Refer to Section 10 for troubleshooting.

PRELIMINARY Connecting Contact Alarms to a Unison System
6.7 Connecting Contact Alarms to a Unison System
The Unison Main Hub can generate (source) two contact alarms as well as sense an
external contact alarm.
• Alarm Source
The Main Hub has two alarm contacts, major and minor errors. These contacts are
normally-closed (NC) and will open when an internal alarm is detected.
• Major error is active when any faults or disconnects are detected.
• Minor error is active during a lockout or warning, or when the end-to-end sys-
tem test is not valid.
•Alarm Sense
The Main Hub can monitor an external alarm contact using this feature. The port
can be configured for normally-open (NO) or normally-closed (NC) contacts. The
interface expects a set of floating contacts. An external voltage source is not
required for this interface. AdminManager or OpsConsole is used to monitor the
port status.
The following table lists the alarm types, equipment that Unison is connected to,
cable(s) used, and the errors (major and/or minor) that are detected.
Note that only major errors are supported on MetroReach and LGCell, and that the
5-port Daisy-Chain Alarm Cable supports only major errors as well. Therefore, using
the 5-port Daisy-Chain Alarm Cable with equipment that supports both major and
minor errors will result in only major errors being detected. This is also the case when
using the Alarm Source Daisy-Chain Cable, which supports both major and minor
alarms, with MetroReach or LGCell because these systems only support major errors.

to the sense input pins on the Unison Main Hub. You must use this adapter cable, as
illustrated in Figure 6-11, with the 5-port Daisy-Chain Alarm Cable or the Alarm
Source Daisy-Chain Cable when connecting LGCell to Unison.
