3. INTRODUCTION
This manual describes how to install an ISM Radio Network consisting of the ISM Tower Top Radio and
the optional Backhaul Router. Because each installation is unique, this manual is designed only as a guide
for installing these products.
3.1 PRODUCT DESCRIPTION
The ISM Radio System extends the reach and signal strength of the overall OpenSky® network and
provides essential connectivity to ISM devices.
The ISM Network provides:
x Extended reach without high profile towers.
x Point-to-multipoint connectivity to extend the coverage area.
x Low-latency links with minimal impact on OpenSky network performance.
x Serial Line Internet Protocol (SLIP) and Internet Protocol (IP) packet processing.
Data and voice network controllers for the OpenSky network are located at the Operation Center. From
the Operation Center, voice and data packets are routed:
x Locally to other ISM devices.
x To another Operation Center.
x Through Interoperability Gateways to non-OpenSky networks.
Each tower site can be equipped with an ISM radio for one-hop communication directly to cell sites. In
addition, to enable the radio to function as a repeater where a link between a cell site and a tower site
cannot be made with a single hop, an additional ISM radio can be connected via fiber to an existing link.
For additionally supported configurations, refer to the ISM Radio Network Design Guide.
Cell sites are an extension of a tower site’s network of OpenSky Base Stations.
3.2 COMPONENTS
3.2.1 ISM Radio
The Tower Top ISM radio communicates with an ISM radio operating at each cell site. The Cell Site ISM
radio provides an interface to the OpenSky Base Station co-located at the cell site.
14
3.2.2 Backhaul Router
The Backhaul Router performs the protocol processing and enables an ISM radio to communicate to an
industry standard Network Access Router using an Ethernet 10base-T connection.
The Network Access Router connection (a T1 Point-to-Point microwave link) terminates at the Operation

3.3 SUB-SYSTEM COMMUNICATION LINKS
The ISM radio is a Direct Sequence Spread Spectrum (DSSS) radio compliant with the FCC Part 15.247
regulations. It operates in the unlicensed ISM frequency band available for public use, between 2.400-
2.4835 GHz.
The radio operates as a subsystem within the OpenSky network to provide point-to-multipoint
communication links between tower sites and cell sites.
The ISM link extends a tower site’s coverage area beyond the devices it can reach directly. Areas poorly
served by high profile tower sites due to budgetary constraints, remote location or topographical
challenges can be affordably and reliably served from a cell site with optional ISM repeater site(s) in an
ISM subsystem.
3.4 RADIO OPERATING MODES: MASTER AND SLAVE
The ISM radio can be configured to operate in either of two modes: Master or Slave.
MM102365V1 Rev. B
3.4.1 Master
A radio in Master mode controls the RF communications path of up to six radios configured in Slave
mode. A Master operating in Time Division Multiplexed (TDM) order initiates all RF communications.
In short, the Master radio addresses all associated Slave radios in round-robin fashion, giving each in turn
the opportunity to transmit or receive ISM addressed voice and data packets.
3.4.2 Slave
A radio in Slave mode transmits and receives segmented IP packets encapsulated with ISM headers only
when addressed by its associated ISM Master radio. The Slave radio buffers data received from its SLIP
(or fiber optic) interface until granted the time slot to transmit to its respective Master. A Slave radio has a
maximum amount of data that is transmitted in any given time slot provided by the Master.
It should be noted that an ISM Master radio is also capable of communicating with
NOTE
another ISM Master radio depending on the system design.
3.5 ISM NETWORK CONFIGURATION
Figure 3-1 shows an ISM Tower Top radio supporting six cell site ISM radios. In this configuration, the
tower site is equipped with several DCX Base Station Units and a Backhaul Router with a single Master
ISM radio acting as a hub.
15
MM102365V1 Rev. B
3.5.1 Networked Master/Slave
The Master radio communicates with up to six Cell Site (or repeater, or Slave) radios. Each operates at
2.4 GHz and burst transfers the data using a 1 Mbps half duplex air link. The Master radio manages a
Time Division Duplex (TDD) protocol to service each Slave.
3.5.2 Packet Path To The Tower Site
The tower site functions as a relay. IP packets destined for a cell site OpenSky Base Station are routed to
the appropriate tower site using the T1 Point-to-Point Microwave link in a manner identical to packets
destined for OpenSky DCX Base Stations at that tower site.

The Network Access Router is a component that includes a Cisco 3600 or other Ethernet
NOTE
10Base-T Router.
3.5.4 Packet Path to the Cell Site ISM Radios
The Master radio, in turn, routes the IP packets to the appropriate Slave radio. The Slave radio then passes
the IP stream to the associated OpenSky Base Station unit co-located at the cell site via an EIA-232 SLIP
interface.
The TDM system has the capacity to deliver bi-directional SLIP data at 38.4 Kbps to each Slave radio.
3.6 OPENSKY APPLICATIONS
Depending on network configuration requirements, ISM radios can operate as Standalone Repeaters or as
part of a Cell-Drop-and-Repeat setup.
3.6.1 Standalone Repeater Operation
x Two radios are used in a Repeater configuration, whether in Repeater or Cell-Drop-and-Repeat.
x Regardless of the setup, radios are always configured in Master/Slave combinations.
x A Master radio (whether at a primary tower site, repeater site or Cell-Drop-and-Repeat) can always be
configured as a multipoint radio.
3.6.2 Cell-Drop-and-Repeat Operation
In a Cell-Drop-and-Repeat setup, one radio operates as a standard Slave in communication with the
primary tower site. A second radio at a repeater site or Cell-Drop-and-Repeat site is configured as a
Master radio similar to a tower site.

5.4 SAFETY RECOMMENDATIONS
The guidelines should be studied prior to working on the Backhaul Router or any equipment powered by
electricity.
x Locate the emergency power-off switch. In the event of an electrical accident, it is necessary to turn
off the power quickly.
x Power should be turned off and cord unplugged to eliminate all chance of an electrical accident
before installing or removing a chassis or working near the power supplies.
MM102365V1 Rev. B
x Installers should not work alone if potentially hazardous conditions exist.
Jewelry must be removed (including rings, necklaces, and watches) before working on
equipment connected to power lines. Metal objects will heat up when connected to power
CAUTION
and ground and can cause serious burns or weld the metal object to the terminals.
5.5 HAZARD WARNINGS
Dangerous Voltages. The Backhaul Router uses –48 VDC or 110 VAC power. These voltages are
dangerous and can cause severe electrical shock. The following precautions must be observed when
operating or maintaining this equipment.
x Never alter or disconnect the ground connection on the unit or the power cord.
x Never connect an AC source if connected to –48 VDC.
x Never operate this equipment with the covers removed.
An electrical shock hazard exists if this device is connected to 230 VAC mains where both
sides of the AC line are floating above ground. The circuit breaker protects only one side
of the AC input line. Even if the circuit breaker opens because of high current, the other
WARNING
side of the line in a floating system is still energized.
21
MM102365V1 Rev. B
5.6 ELECTROSTATIC DISCHARGE
ElectroStatic Discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic components are handled without adequate precautions or proper earth grounding and can result
in complete or intermittent failures.
ESD-prevention procedures must be followed when removing and replacing components.
x Ensure that the chassis is electrically connected to earth ground.
x Installers must wear an ESD-preventive wrist strap and ensure it makes good skin contact. To
properly guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
x The clip must be connected to an unpainted surface of the chassis frame to safely channel unwanted
ESD voltages to ground.
x If no wrist strap is available, grounding can be achieved by touching the metal part of the chassis.
5.7 CABLING CONSIDERATIONS
When planning the installation of the Backhaul Router to a Network Access Router, it is necessary to
consider distance limitations and potential ElectroMagnetic Interference (EMI) as defined by the
Electronic Industries Association (EIA).
Each installation connection must be planned to accommodate the following unique distance limitations.
5.7.1 Ethernet Connections
The distance limitations for Ethernet 10Base-T indicate a maximum segment distance of 328 feet
(100 m).
5.7.2 ISM Radio Power/Fiber Optic Connections
The distance limitations for the ISM radio power and fiber optic cable indicate a maximum cable length
of 600 feet (183 m). The distance is limited primarily to the voltage drop due to current resistance loss in
the power cable.
5.7.3 Maintenance Port Connection
The maintenance port interface is the EIA/TIA-232 (RS-232C). Travel distance for EIA/TIA-232 signals
is determined by bit rate. Generally, the slower the data rate, the greater the distance a signal can travel.
Table 5-1 shows the standard relationship between baud rate and maximum distance.
22
MM102365V1 Rev. B
Table 5-1: EIA/TIA-232 Baud for Distance Rates
DATA RATE (BAUD) DISTANCE (FEET) DISTANCE (METERS)
2,400 200 60
4,800 100 30
9,600 50 15
19,200 50 15
38,400 50 15
NOTE: The baud rate for the maintenance port is fixed at 19,200 baud, so the maximum
cable limit shall not exceed 50 feet or 15 meters.

6. INSTALLATION
6.1 TOWER TOP ISM RADIO ENCLOSURE INSTALLATION
The Tower Top ISM Radio Enclosure is designed for mounting outdoors on rooftops and poles, building
sides and the sides of telecommunications towers. It must be properly mounted, cabled, dressed and tied
off, and all grounding cables and interconnections must follow the instructions provided.
Do not proceed with installation until earlier sections of this manual have been studied and
safety precautions and hazard warnings read and understood.
Failure to follow installation guidelines could pose physical danger along with the risk of
CAUTION
Cable clamps, mounting brackets, ground clamps and cables for both the radio and Backhaul Router must
follow the specifications set out in this manual as regards the following:
x Chassis ground cables for Tower Top ISM Radio Enclosure, #6 AWG or larger, 7 strands or larger.
permanently disabling equipment.
Qualified professional technicians should install this equipment only.
x Grounding of outer conductor on RF cable, clamps to use, grounding cable to use.
x Rack grounding cable Backhaul Router.
x Lightning protection device on DC power grounding specifications.
x Fiber Optic cable clamps: what to use, where to tie off and how many feet apart.
x Brackets, bolts etc for mounting radio.
x Termination of antenna port if not used.
6.1.1 Power and Grounding Requirements
The radio operates using +12 VDC to +16 VDC input voltage. Its maximum power requirement is 12
Watts. DC Power is provided via the Fiber Optic Cable assembly (MAIROS0002-XXXXX).
The Enclosure has a grounding lug on the bottom of the chassis. This grounding lug must be connected to
a ground reference using #6 AWG stranded wire or heavier gauge.
6.1.2 Lightning Protection
The Tower Top ISM Radio Enclosure contains integral lightning protection. For tower top installations,
or any installation in which the radio is not co-located with a Backhaul Router, no additional precautions
should be required to protect against lightning.
24
MM102365V1 Rev. B
Figure 6-1: ISM Tower Top Radio Enclosure
6.1.3 ISM Radio Co-Located with the Backhaul Router
The ISM radio requires DC power in the range of +12 VDC to +16 VDC. The Backhaul Router provides
+15 VDC on its rear panel. When the Backhaul Router is present, it is the preferred power source for the
ISM radio.
Because it is often co-located with a Backhaul Router in a ground-level enclosure, special care must be
taken to protect the Backhaul Router and other co-located equipment from lightning surges and spikes.
25
MM102365V1 Rev. B
A lightning suppressor should be well grounded and mounted at the egress point to the building (or
enclosure) that houses the Backhaul Router.
A Polyphasor (part number IS-17 VDC-30A-FG) or comparable component may be used to provide
lightning protection on the +15 VDC power lines.
6.1.4 Connect Radio to Another ISM Device
The devices that constitute the ISM network are ISM Master radios, ISM Slave radios, and Backhaul
Routers. An ISM radio can be connected to another ISM device via the RF link, the Network Port, or the
SLIP port. Additionally, the radio uses its SLIP port to connect to an OpenSky Base Station Refer to the
Assembly Diagram in Section 12.2.
Where two ISM Cell radios reside at the same site, only the first radio requires an RF link to
