1.5. SAFETY INFORMATION

Personnel installing OpenSky rack-mounted components at a communication site should

be aware of a number of potential hazards. These hazards may be associated with

OpenSky electronic and Radio Frequency (RF) equipment, radio antennas used with

these components, or with the environments in which components are housed. Keep in

mind that when working in the field, hazards associated with equipment, antennas, or

environmental conditions that are part of applications other than OpenSky radio may also

present risks.

Hazards you may encounter include the following:

• RF emissions

• Electrical shock

• Lifting of heavy objects

• Falling objects

• Falls

• Poor ergonomic design

• Chemical exposure

Working around the hazards listed above does not necessarily pose any outstanding risk

to health or safety - however, knowledge of these possible hazards is vital to working

safely.

MM102225V1, Rev. B

The safety guidelines and precautions presented in this manual do not replace M/A-

COM's specific requirements. The primary responsibility for health and safety standards,

practices and guides lines in a M/A-COM project lies with the Environmental, Health &

Safety (EHS) department.

All M/A-COM managers, supervisors, or subcontractors responsible for work associated

with OpenSky equipment must be completely familiar with and prepared to comply with

all applicable EHS guidelines and requirements. Although M/A-COM's policy requires

that all contractors and visitors must be adequately trained prior to working on any M/A-

COM project, this does not mean M/A-COM is responsible for conducting or providing

this training.

The following safety precautions must be observed during all phases of operation,

service, and repair of this product. Failure to comply with these precautions or with

specific warnings elsewhere in this manual violates safety standards of design,

2.0 SITE PREPARATION

2.1 INTRODUCTION

This section provides instructions for preparing the site and other installation items,

which must be completed prior to installing OpenSky Communication equipment. The

areas covered include the following:

Antenna System - This includes installation of the antenna tower, receive and transmit

antennas, tower top amplifier and the installation of the transmission lines from the

antenna to the tower top amplifier to the equipment shelter.

Site Requirements - Information is provided concerning various factors, which may

affect the physical location of the equipment facility.

Facility Preparation - This section provides information for preparing the facility prior

to installing the equipment. This information includes proposed equipment layout,

environment, electrical power, equipment room grounding and telephone line installation.

2.2 ANTENNA SYSTEM

This section covers installation of the antenna system, including RF cables from the

antennas to the equipment room wall feedthrough.

Antenna systems are generally installed by crews trained and equipped for working on

antenna towers. As a result, this manual assumes the Antenna systems are installed by

crews with the specialized equipment and skills required for working on towers and

installing the antenna cables. However, it may be necessary for the system installer to

provide information and directions to the crew installing the antenna system and to verify

proper installation.

2.2.1 Antenna Mounting

The antenna tower must allow antenna mounting that provides isolation of at least 25 dB

between the TX and RX antennas. This is necessary to avoid interference in the trunked

receivers caused by the trunked transmitters. An isolation of greater than 25 dB is easily

obtained by placing one antenna directly above the other on the tower (minimum 10-foot

separation).

2.2.2 Transmission Lines

When installing the transmissions lines, refer to the diagrams contained in Antenna

System Maintenance Manual LBI-38983.

2.2.2.1 Length

The length of the main coaxial cable for each antenna is planned as a continuous run with

no connectors or splices between the antenna and the equipment room. Each cable

includes a 50-foot allowance for the distance from the bottom of the tower to the

equipment room. Smaller diameter, more flexible coaxial cables are used at both ends of

the main coaxial cable to facilitate installation.

MM102225V1, Rev. B

2.2.2.2 Minimum Bending Radius

Always adhere to the minimum bending requirements provided by the manufacturer. For

Andrew Products, the values are:

CABLE SIZE BENDING RADIUS

1/4-inch

1/2-inch

7/8-inch

1-5/8-inch

1-inch (25 mm)

1.25-inch (32 mm)

10-inches (250 mm)

20-inches (510 mm)

2.2.2.3 Hoisting Grips

Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable

without damaging the cable. Each hoisting grip is capable of safely lifting 200 feet of

cable without causing damage. Therefore, one hoisting grip is required for every 200-foot

section of cable. The grips may be left attached to the cable after the cable installation is

completed.

Some situations may require more hoisting grips, such as:

• An installation to a tower which is on top of another structure.

• Any installation where the length of cable that must be lifted is greater than the

height of the tower.

In these situations, additional hoisting grips should be ordered.

WARNING

Under NO conditions should RF connectors be used to attach a rope or cable.

2.2.2.4 Hangers and Adapters

Coaxial cables on the tower should be secured at intervals of 3 feet (maximum).

Securing 7/8-inch and 1 5/8-inch diameter coaxial cables is accomplished by using either

hangers or hanger-adapter combinations. The hangers secure the cables to the tower

structure by using prepunched holes or attachment adapters.

When the tower structure is prepunched with 3/4-inch holes, snap-in hangers are used

(preferred method).

When the tower is prepunched with 3/8-inch holes, the hanger is secured by a 3/8-inch

bolt.

For towers without prepunched holes, the hangers are attached with adapters. The type of

adapter depends on the type of tower structure. Adapters are available for either angle

tower members or round tower members.

MM102225V1, Rev. B

Adapters for each antenna system are selected when ordering the system. If the coaxial

cable must be attached to a structure that is not compatible with any of the above hangers

or adapters, then additional materials or other special considerations may be required.

To secure 1/4-inch or 1/2-inch vertical or horizontal coaxial cables of any size, use UV

resistant, black nylon cable ties.

2.2.2.5 Weatherproofing

A kit of weatherproof tape is provided to protect coaxial connectors from the outside

elements. One roll of tape is sufficient to weatherproof four exposed outside connector

joints (More than four are required with a Top Tower Antenna).

2.2.2.6 Antenna Grounding

Grounding kits are installed to prevent the radio system from being damaged by

lightning. A grounding point should be installed at the top end of each coaxial cable run

on the tower. A second grounding point should be installed on each cable at the bottom of

the tower and a third grounding point on the cable at the point where the cable enters the

building, if the tower-to-building length is greater than 20 feet. For cable runs on the

tower greater than 200 feet, additional grounding points should be installed at each 200-

foot interval. Grounding points should be installed at the Tower Top Amplifier as well.

2.3 TOWER TOP AMPLIFIER

The Tower Top Amplifier (TTA) should be installed near the receive antenna in order to

improve the receive (inbound) channel performance. The amplifier should be mounted to

the tower structure with corrosion resistant hardware and grounded to the tower structure

with a #6 AWG solid or stranded copper conductor. All TTA ground connections,

whether to tower frame (angular or circular) or a tower ground buss, should be made with

corrosion resistant hardware.

For the TTA a "drip loop" in the RF cable from the antenna is recommended.

2.4 SITE REQUIREMENTS

This section provides information for preparing the facility prior to installing the

equipment. This information includes proposed equipment layout, environment, electrical

power and telephone line installation.

2.4.1 Floor Plan

Direct access to the area (for antenna cables and personnel) between the tower and the

equipment room is necessary. Standard floor plans for the equipment cabinets are side-

by-side cabinets. Lengths of interconnect cables supplied are based on these standard

floor plans. If a floor plan other than a standard floor plan is used, longer interconnect

cables may be required.

2.4.2 Operating Environment

The equipment room where the base station equipment is installed must meet the

environmental conditions listed in the Station Specifications section of this manual.

MM102225V1, Rev. B

Although the temperature requirements for individual pieces of trunked equipment may

be broader, when several units are assembled together in a cabinet more heat is generated.

Because of this condition, the ambient room temperature outside the cabinet must be

lowered to ensure the temperature inside the cabinet does not exceed the limits for the

equipment.

2.4.3 Electrical Power

Normally, OpenSky equipment is powered by –48 VDC. If the OpenSky cabinet is

equipped with an AC power supply and an AC power cord, a 20-amp circuit breaker for

each AC supply is recommended.

Receptacles must be installed within reach of the power cord(s). This can be on the wall

behind the cabinets, in the floor under the cabinets, or in the cabinet top cable ducts. Each

station power supply power cord is about 3 meters (9.8 feet) long, starting at the back of

each power supply (two or three different heights) within the rear of each station cabinet.

Each cord plugs into an AC Outlet which has a cord length of about 3 meters (9.8 feet)

long.

When required, the AC power supplies are omitted from the station cabinet. In this case,

DC power must be supplied to the base stations from an external -48 VDC power source

through a separate 30-amp circuit breaker for each base station.

Additional equipment may be required if other types of power sources are used, or if the

power source is not within reach of the individual AC power cords.

2.4.4 Equipment Room Grounding

Ensure all equipment and facilities meet the requirements for grounding and lightning

protection.

Installation Manual AE/LZT 123 4618/1 - Standard For Site Grounding and Protection

provides instructions for proper grounding of sites and radio equipment. These

procedures should be observed in order to protect the equipment and service personnel

from lightning and other sources of electrical surges. This manual is included as part of

system documentation.

2.5 ANTENNA SYSTEM QUALITY AUDIT

Before installation of the antenna begins fill out APPENDIX J- INSTALLER PROFILE

DATA SHEET. After the Antenna System is installed it should be inspected before the

installers leave. A checklist of tasks performed on the antenna system is provided in

APPENDIX K - ANTENNA SYSTEM INSTALLATION CHECKLIST. Be sure to

complete this visual inspection before the installers leave, so any obvious errors can be

corrected.

1. Using field glasses (if necessary) view the Antenna System from various positions on

the ground. Using copies of the Antenna System Installation Checklist found in

APPENDIX K, fill out a checklist for each antenna as you go through the following

inspection procedure. This will provide a record of the inspection, and of some

antenna information for future reference.

2. Record the make of antenna.

3. Record the type of antenna (omni or directional).

MM102225V1, Rev. B

4. Record the design gain of the antenna.

5. If the antenna is directional, record the bearing of the main lobe, using the magnetic

declination for True North. If it is Omni, write "Omni" in the data entry line.

6. Record the height of the antenna above ground.

7. Confirm that cable-hoisting grips were installed as required to prevent damage to the

coaxial cable. Hoisting grips should have been installed at the antenna end of the

cable plus one for each 200 feet of cable length.

8. Confirm the cable is secured to the tower at intervals, which do not exceed 3 feet.

9. Confirm the cable is grounded at the top of the tower.

10. Confirm the cable is grounded at the point where it leaves the tower.

11. Confirm the cable is grounded at the point where it enters the building.

12. Confirm the coaxial cable run looks OK. The cable must be tight (nothing to flap in

the breeze), have no dings or kinks, be one continuous run (no connectors or splices),

and not exceeding the minimum bending radius on any bend.

13. Confirm the cable weather tight feedthrough is properly installed where the cable

enters the building.

14. Confirm the coaxial connectors have been properly weather sealed.

15. Confirm the cable entrance to the building has been properly weather sealed.

MM102225V1, Rev. B

3.0 BASE STATION INSTALLATION

The following sections present the steps required for installation of populated OpenSky

base station equipment racks at a communications site.

To a certain extent, installations must be planned site-by-site, because of the wide variety

of installation conditions and configurations. Installers will encounter many types of

equipment enclosures and tower site equipment configurations. The Site Deployment

Order (SDO) should include an accurate site layout map, information to designate rack

locations, and other necessary installation information.

3.1 BEFORE INSTALLATION OCCURS

Before the antenna installation date, collect the information from the Site Deployment

Order specific to site access. Site-specific information includes the following:

• Permission to access the site

• Directions to the site

• Keys and lock combinations to access the site and equipment shelter, or points of

contact to obtain them

• A drawing or description of each site showing where the equipment is to be installed

inside the enclosure

• Information about work practices needed to work safely at the site

The installation procedure below assumes that the installation team has secured

permission to access the communications site and has obtained the necessary keys or lock

combinations.

CAUTION

Keep working environment clean!

Control dust, dirt, and shavings for safety, and to protect equipment.

Be sure to follow installation procedures carefully!

3.2 BASICS

Generally, the OpenSky base station fits into two or more equipment racks. Each rack is

nominally seven feet high and twenty-four inches wide. The populated racks must be

installed inside a weatherproof enclosure near the base of a communications tower. If an

OE-100 Outdoor Enclosure is used, the OpenSky equipment is mounted to the mounting

rails provided within the enclosure (Refer to OE-100 Outdoor Enclosure Maintenance

Manual MM102226V1). The Base Station installation procedure addresses the following:

• Installing the equipment racks after they have been transported to the

communications site and moved into the equipment shelter

• Making inter-rack cabling connections

MM102225V1, Rev. B

• Connecting the power supply and site subsystems external to the OpenSky equipment

racks

3.3 SECURING EQUIPMENT RACKS TO THE FLOOR

Move the racks into the designated positions and prepare to bolt them to the floor. In rare

cases, bolting to the floor may be prohibited. In those cases, bolt the racks to each other

for stability.

Procedure:

1. Using a template, mark bolt locations for each equipment rack to be installed.

2. Drill pilot holes (Drill any required pilot holes to the specified depth of 1-1/2").

3. Drill 1/2" diameter holes for wood and concrete floors.

4. Move racks into position over bolt marks. In general, racks are placed side-by-side in

numerical order, with Rack #1 leftmost when viewed from the front.

5. If necessary, level the racks. The racks should be, at a minimum, approximately

level. If necessary, shim the racks so they are level by eye (use of an actual level is

better).

6. Align the front of the racks.

7. Bolt equipment racks to the floor. Follow the procedure below corresponding to the

type of floor in the shelter. In general, equipment installers will encounter four types

of floor: concrete, concrete covered with linoleum, wood, and raised floors. The

procedure for each type is as follows:

• For concrete floors, use 1/2" drop-in expanding anchors with an insulating nylon

washer under the fastener head to anchor the racks (see Figure 3-1: Bolt

Assembly Hardware and Figure 3-2: Nylon Washer and Bolt Assembly).

1. Drill pilot holes for the anchors using the appropriate-sized carbide-tipped

drill bit. The pilot holes must not exceed 1-1/2" in depth.

2. Insert the anchors into the pilot holes.

3. Place insulating phenolic strip(s)2 and under the cabinets/racks before bolting

them in place.

4. Place the cabinet/rack over the holes.

5. Assembly the bolts, fender washers and nylon washers.

6. Insert the bolt and washer assemblies into the pilot holes.

7. Tighten the bolts until firmly set (see Figure 3-3: Concrete Floor Mounting

and Figure 3-4: Bolt Assembly Used to Bolt Rack to Concrete Floor).

CAUTION

Be careful not to over tighten bolts to avoid breaking the phenolic bushings.

2 Phenolic strips are only required if the floor is pure concrete. Concrete floors covered with linoleum do not require phenolic

strips.

• For wood floors, use a lag bolt with an insulating nylon washer under the head to

bolt the racks to the floor. Insulating phenolic strips under the racks are not

required. No pilot hole is needed on wood floors.

• For raised floors, the rack attachment procedure is quite different. The first and

last racks in the row are bolted to the sub-floor as shown below. The remaining

racks are bolted to the end racks, to each other, or both. Insulating phenolic strips

must be placed under each rack (see Figure 3-5: Raised Floor Rack

Attachment).

3.4 CABLING EQUIPMENT RACK COMPONENTS

Once the racks have been installed, interrack cable connections must be made, and racks

must be connected to a power source and grounded, as well as connected to external

communications sub-systems such as antennas. Follow this procedure in accordance with

M/A-COM, Inc. Quality Standards Manual GQM0221. Possible rack-ups of equipment

cabinets are shown in Figures 6 and 7.

overhead ladders, routing cables under raised floors, and so on.

4. Route DC power cables together and maintain at least two inches (2") spacing

between the DC power cable bundle and other types of cables.

MM102225V1, Rev. B

3.4.4 Connect Grounding Cables to Equipment Racks

Attach a ground cable to each rack.

1. Run #6 Green grounding cable (stranded copper) from each rack ground directly to

the single-point ground bar in each enclosure.

CAUTION

All bends in the grounding cables must be < 70-degrees.

All bends in the grounding cables must have minimum bend radius of 8 inches.

See the M/A-COM Quality Standards Manual (GQM0221) for more information.

2. At a single point cabinet ground, use a two-hole lug to attach the ground cable. Route

the cables as specified by the installation procedure, using existing cable trays and

overhead ladders, routing cables under raised floors, and so on (see Figure 3-20:

3. Route the ground cables together and maintain at least two inches (2") spacing

between the ground cable bundle and other types of cables.

3.4.5 Connect Antenna Cables to Equipment Racks

Attach the antenna cables to the communications equipment.

1. Prior to the communications equipment installation, one or two antennas will have

been installed at the site. The antenna cables will have been terminated inside the

enclosure onto a metal plate (ground plane).

• For single antenna sites, the incoming antenna cable terminates in a

PolyPhaser® (surge protector) attached to the ground plane.

• For dual antenna sites, both the transmission and receiving antennas' incoming

cables terminate in a PolyPhaser (surge protector). Systems with tower-top

amplifiers require a special DC Injection/DC Path Protector (PolyPhaser

#DC50LNZ+30-MA). The 1-5/8" cable is the TX cable and the 7/8" cable is the

RX cable when used with a Tower Top Receive Amplifier.

Figure 3-22: Dual Antenna PolyPhasers (Surge Protectors)

2. Attach drop cables from the PolyPhaser to the appropriate antenna connection points

in the OpenSky equipment racks.

3. Route the cables appropriately, or as specified by the installation procedure, using

existing cable trays and overhead ladders, routing cables under raised floors, and so

on.

4. Maintain at least two inches (2") spacing between the antenna cables and other

cables.

MM102225V1, Rev. B

3.4.6 Connect the T1 Network

Connect the high-speed digital T1 (telephone) network Interface to the Site Access Server

as defined by the Site Deployment Order.

NOTE

In most installations, this connection goes to microwave equipment.

3.4.7 Site Clean Up

Before leaving, remove any debris, such as wire clippings, metal shavings, dust mounds,

etc. from the site.

3.5 COMPLETING THE INSTALLATION

Once the OpenSky equipment has been installed, perform field testing as detailed in

Section 4.0 SITE TEST PROCEDURES to verify operation according to specifications of

installed equipment racks with externally connected subsystems such as antennas.

Procedures:

1. Perform testing to verify correct operation and performance of the installed

equipment racks, following the procedures specified in Section 4.0 SITE TEST

PROCEDURES.

2. Set HPA transmission power level, following the procedure specified in Section

7.06.7 -TX POWER CALIBRATION (MANDATORY).

3. If problems occur during installation, describe them and detail how they were

resolved. If the installation could not be completed, describe the obstacles and clearly

explain what was done and what remains to be done.

MM102225V1, Rev. B

4.0 SITE TEST PROCEDURES

4.1 PURPOSE AND SCOPE

This section describes post installation tests required for compliance testing of the M/A-

COM Wireless Systems OpenSky Digital Base Station. This section defines and details

the test plan and methodology for each test.

Objective: This test confirms a base site receive channel is not corrupted by site specific

noise or interference. Site installation and site gain optimization should be completed

before this test is performed. The NIMCAS site optimization program provides an

expected difference between terminated and antenna connected quieting tests. Measured

results should be within 2 dB of this value.

This section covers tests that perform two functions:

• Verify that all contractual requirements as detailed in the system Requirements

Traceability Verification Matrix, (RTVM), are met. These tests are identified as

mandatory and are linked to the relevant section for the RTVM.

• Ensure that the site, as installed, is operating at optimum performance. These tests are

not mandatory but clearly have impact on some of those that are.

To ensure that the system is installed and configured correctly, the following procedures

must be performed. In addition, several tests are performed to validate the RF

performance of the station and to ensure compliance with the station FCC license.

This section is therefore divided into the following areas:

• Verification Testing

• Equipment Configuration

• Compliance Testing

• Performance Testing

• Operational Testing

• Network Connectivity

• Final Operating Capability

• Appendices: Supplemental information on equipment configuration and control

access.

⇒ Base Site Configuration Procedure should also be consulted for configuration

questions (see APPENDIX F - TYPICAL BASE STATION

CONFIGURATION).

⇒ Installed Site Cavity Tuning Procedure should also be consulted for Filter Tuning

(see APPENDIX H - VERIFICATION TESTING – TRANSMIT FILTER

TUNING).

MM102225V1, Rev. B

4.2 OVERVIEW OF OPENSKY BASE SITE EQUIPMENT

An OpenSky base station consists of a variety of products and includes radio transmitting

and receiving equipment, RF distribution equipment and network communications

system interface equipment.

OpenSky is a digital system and has some significant differences in terms of fixed

network connectivity to that commonly seen with conventional analog systems. In

particular, base station controllers (BSCs) communicate via an access server and are

connected back to a central office or dispatch center via digital circuits.

OpenSky base station equipment is available in five primary RF configurations. This

document covers Types 1, 2, 3, and 4 listed below. Type 5 is covered separately.

1. Primary site with separate transmit and receive antennas: Referred to as a Tower Top

Site.

2. Primary site with a single antenna for transmit and receive: Referred to as a Duplexed

Site.

3. Outdoor Enclosure with separate transmit and receive antenna.

4. Outdoor Enclosure with a single antenna for transmit and receive.

5. Low profile site providing coverage fill: Referred to as a Cell Site.

4.3 TEST METHODOLOGY

Equipment configuration and testing must be performed in accordance with the

instruction given in this document. Tests must also be conducted in the order given in this

document as adjustments made during certain procedures may affect the results of other

tests.

Testing an installed base site comprises performing standard forward and reverse channel

tests to ensure correct operation of the entire installation. Testing also verifies physical

and application layer connectivity to the Regional Operations Center serving the site

under test via a communications link.

Required specifications are verified using one of the following methods:

1. Inspection: An observation or examination of an item against the applicable

documentation to confirm compliance with the requirements.

2. Analysis: Interpretation, interpolation, or extrapolation of analytical or empirical data

under defined conditions of reasoning to show theoretical compliance with stated

requirements.

3. Demonstration: Verification of an operational or functional capability by one or

more performances before qualified witnesses, as designated by the customer.

Instrumentation or data recording beyond that provided indigenously by the elements

to be verified shall generally not be required.

4. Objective Test: Performance of a functional operation under specific conditions

involving the use of instrumentation, special test software, and/or special test

equipment to generate, acquire, and/or record data. This method may include an

analysis of test data.

MM102225V1, Rev. B

4.4 PREPARATION

To prepare for the start of testing, it is important that all test equipment be powered up

now and allowed to thermally stabilize. Begin by powering up the Communications Test

Set HP 8920.

Record the specifics of each of the system components.

Before testing the complete system, verify that the system is cabled correctly. The tower-

mounted receive amplifier will not power up until it senses that the indoor control panel

has been connected via the RF feed cable and the multi-conductor control cable. The

initial sections of this procedure describe how to check for correct installation,

particularly those areas that were disturbed as part of the shipping process.

4.5 RECORDING TEST RESULTS

The main body of this document provides space for the recording of all test results and

equipment configuration parameters. These must be supplemented where indicated by

equipment configuration hardcopy printouts taken for each RF channel being tested.

CONNECTING A PC TO A BASE STATION23

There are three ways to connect a personal computer to OpenSky Base Station equipment:

1. Direct connection to the RS-232 port of the device under test.

2. Direct connection to the Console Port of the Access Server and telnet to the device under test.

3. Direct connection to the Ethernet port of the Access Server and telnet to other devices.

Direct connection to any device is the simplest approach, but requires cables to be swapped and various

configurations for the terminal emulation application used as the PC user interface. The table below

provides connection details for all rack equipment.
