Preface P REFACE This manual provides installation instructions for ADC® InterReach Spectrum™ Remote Access Units. InterReach Spectrum User Documentation The InterReach Spectrum user documentation is intended for system administrators, engineers and installers responsible for planning, administering, configuring, and maintaining ADC InterReach Spectrum systems. Table 1 lists the manuals that correspond to this InterReach Spectrum release. Table 1.
Preface 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).
Product Overview P RODUCT O VERVIEW 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.
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 CATV cable. The MRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The MRAU also receives 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.

Product Overview Secondary Remote Access Units A Secondary Remote Access Unit (SRAU) receives FWD IF signals from the MRAU, using 75 CATV cable. The SRAU converts the IF signals to RF and sends them to a passive RF antenna using 50 coaxial cable. The SRAU, through the MRAU, also receives configuration information and power from and sends its status information to the IFEU. The SRAU receives REV RF signals from a passive RF antenna using 50 coaxial cable.

Off • During initial power up, SRAU is powering up and waiting for IFEU communications. Green • Unit has no alarms or a Minor alarm is active.
Install the RAUs and Antennas NOTE: RAUs are suitable for use in environmental air space in accordance with Section 300-22(c) of the National Electrical Code, and Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, CSA C22.1. NOTE: You can place the RAU, without its fastening hardware, on a flat surface, such as a shelf, desk, cabinet, or any other horizontal surface that allows stable placement, with the mounting base facing down to the mounting surface.
Install the RAUs and Antennas Connect the IFEU to the MRAU NOTE: The IFEU should be powered up before starting this procedure; see the InterReach Spectrum Expansion Module Group Installation Guide (ADCP-77-167). 4 Follow these rules for the CATV cables when connecting the IFEU to the MRAU: • The FWD and REV cables should be close to the same length. • The FWD and REV cables should be the same cable type (both RG6 or both RG11). • A pair of CATV cables connects each MRAU to the IFEU.

Install the RAUs and Antennas Connect the MRAU to SRAUs CAUTION! To prevent interference, do not install an 850/1900 MRAU antenna near an 800/900 SRAU. The 850 MHz band must be 20 feet away from the 800/1900 SRAU’s passive antenna. 7 Use one of the following 6’ and 20’ CATV RG6 jumpers, available for purchase from ADC, to connect an MRAU to SRAUs. ADC Part Number Description Note 300469-0 6’ RG-6 Cable; F Male to F Male CATV cable that connects the MRAU to SRAUs. Two cables required per SRAU.
