Document Cautions and Notes

Two types of messages, identified below, appear in the text:

CAUTION! Caution text indicates operations or steps that could cause personal injury, induce a

safety problem in a managed device, destroy or corrupt information, or interrupt or stop

services.

NOTE: Note text contains information about special circumstances.

General Safety Precautions

CAUTION! Wet conditions increase the potential for receiving an electrical shock when installing or

using electrically powered equipment. To prevent electrical shock, never install or use

electrical equipment in a wet location or during a lightning storm.

CAUTION! This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can

seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do

not look directly into the optical transceiver of any digital unit or exposure to laser

radiation may result. Use an optical power meter to verify active fibers. Immediately

place a protective cap or hood over any radiating transceiver or optical fiber connector to

avoid the potential of dangerous amounts of radiation exposure. This practice also

prevents dirt particles from entering the adapter or connector.

CAUTION! This system is a RF Transmitter and continuously emits RF energy. Maintain a minimum

clearance of three feet (91.4 cm) from the antenna while the system is operating.

Wherever possible, shut down the RAN before servicing the antenna.

Standards Certification

FCC: This equipment complies with the applicable sections of Title 47 CFR, Part 22 (800 MHz Cellular), Part 24 (1900 MHz - PCS), Part 90 (800/900 - SMR), and Part 27 (700 MHz, 2100 MHz - AWS).

IC: This equipment complies with the applicable sections of RSS-131 (800/900 – SMR), RSS-132 (800 - Cellular), and RSS-133 (1900 – PCS). The term “IC:” before the radio certification number only signifies that Industry Canada Technical Specifications were met.

The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.

NOTE: The U.S. Federal Communications Commission (FCC) has developed guidelines for

evaluation of human exposure to RF emissions. The guidelines incorporate limits for Maximum Permissible Exposure (MPE) for power density of transmitter operating at frequencies between 300 kHz and 100 GHz. Limits have been set for portable, mobile, and fixed equipment. ADC products fall in the category of fixed equipment; products intended to be permanently secured and exposures are evaluated for distances greater than 20cm (7-7/8”). Portable devices fall into exposures of less than 20cm, where SAR evaluations are used.

Preface

Antenna gain is restricted to 1.5 W ERP (2.49 W EIRP) in order to satisfy RF exposure compliance requirements. If higher than 1.5 W ERP, routine MPE evaluation is needed. The antennas should be installed to provide at least 20cm from all persons to satisfy MPE requirements of FCC Part 2, 2.1091.

UL/CUL: This will be installed in a restricted access location. This equipment complies, per UL and CUL 50, Standard for Enclosures for Electrical Equipment.

UL/CUL: This equipment complies with UL and CUL 60950-1 Standard for Safety for Information Technology Equipment, including Electrical Business Equipment.

UL: This equipment is UL Plenum rated under UL 2043.

CAUTION! Modifications not expressly approved by the party responsible for compliance could void

the user's authority to operate the equipment.

PRODUCT OVERVIEW

InterReach Spectrum supports up to eight frequency bands in a single system. Each antenna location supports those bands in modular, group pairings. Each location includes a Main Remote Access Unit (MRAU), which can power up to three additional Secondary Remote Access Units (SRAUs). An MRAU supports two frequency bands, and each SRAU can support up to two frequency bands, for a total of up to eight frequency bands. MRAUs and SRAUs are grouped logically, based on common service provider groupings and include, as an example:

• 850/1900

• 700/700 MIMO

• 800/900 SMR

• 1900/AWS.

To add more frequency bands, you connect an SRAU to the existing MRAU.

Figure 1 illustrates how RF and IF signals are sent between Spectrum units and

modules.

Product Overview

Main Remote Access Units

The Main Remote Access Unit (MRAU) receives FWD IF signals from an IF Expansion Unit (IFEU), which is part of the Spectrum Expansion Module Group, using 75 a passive RF antenna using 50 configuration information and power from and sends its status information to the IFEU.

The MRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable. It converts the signals to IF and sends them to the IFEU using 75 cable.
