The User Manuals delivered with the system describes the installation of the entire system but does not include stand-alone operation of the individual components of the system. Therefore, this document describes the equipment setup and operation employed for stand-alone operation of the CPE Roof Unit transceiver, as applicable to compliance testing. For stand-alone testing such as functional checkout or compliance testing, this user’s manual provides the instructions so that the Roof Unit transceiver may be operated at maximum rated output power with automatic power control disabled. In addition, the Roof Unit may be commanded to various operating frequencies within the allocated band of operation and modulated with actual or simulated IF input signals. Exhibit 8 FCC ID: NNSRTU2000-00 4/05/00Page 2 of 4 Instructions for Stand-Alone Operation of the CPE Roof Unit Transceiver Version 2.0 1.0 Scope This document provides the instructions for operation of a single CPE Roof Top Unit transceiver for test purposes (i.e., without the control of the SpectraPoint System). 2.0Introduction The CPE Roof Unit transceivers, when operating under control of the SpectraPoint System, receives QPSK (quadrature phase shift keying) modulated RF signals (downstream telephony, digitized video or digital data) from one or more SpectraPoint Node Transmitters (LMDS Base Station). The CPE Roof Unit likewise transmits a QPSK modulated RF signal (upstream) from the CPE Network Interface Unit (NIU) to the SpectraPoint Node Receivers (LMDS Base Station). For test purposes, the QPSK modulated input signal to the Roof Unit transmitter, at the appropriate center frequency, modulation, bandwidth and level must be provided by test hardware and software which is defined in this document. 3.0Interconnection of Support Equipment The interconnection of the CPE Roof unit with the test fixture and support equipment is shown in figure 4-1. Operational parameters for setup of the support hardware and software is provided in Table 4-1. Using this support test equipment, the CPE Roof Unit will produce a single QPSK phase modulated output at user-selected bandwidths (as in the SpectraPoint System). 4.0 Description of the Test and Support Equipment The support equipment required to operate the CPE Roof Unit in a stand-alone mode is shown in Figure 4-1 and consists of: • DC power source for the Roof Unit electronics card • Transmit enable signal • DC Blocks for both the transmit and receive cables to protect the signal sources and test equipment • Source of the QPSK digitally-modulated signal (Rohde & Schwarz AMIQ Arbitrary Waveform Generator and SMIQ Vector Signal Generator) • Personal Computer with WinSim software to generate the QPSK I and Q Signals at the AMIQ Exhibit 8 FCC ID: NNSRTU2000-00 4/05/00Page 3 of 4 Personal Computer (WinSim Software) (IEEE-488 Interface) AMIQ Arbitrary Waveform Generator SMIQ Vector Signal Generator CPE Roof Unit Test Fixture CPE Roof Unit 75 Ω Cable I/F Input to Transmit Portion and Transmit Enable 75 Ω Cable I/F Output from Receive Portion and DC Power HP 8564E Spectrum Analyzer 120 VAC 60 Hz Power Input Figure 4-1 CPE Roof Unit Test and Support Equipment Exhibit 8 FCC ID: NNSRTU2000-00 4/05/00Page 4 of 4 4.1 Generation of QPSK Test Signals Test signals for the CPE Roof Unit, simulating I/F input from the SpectraPoint Network Interface Unit (NIU), are generated in the AMIQ and transferred by operator command to the SMIQ. The WinSim software program is launched by double-clicking on the WinSim icon or by selection from the Windows Program Start menu. The modulation parameters may be manually entered through the PC keyboard or recalled from predefined parameters stored on disk. The NIU is capable of generating QPSK-modulated signals ranging from approximately 1.5 MHz bandwidth to 10.0 MHz bandwidth depending on a variety of operating rates and error correction schemes required for reliable operation of a SpectraPoint LMDS installation. The CPE Roof Unit test and support equipment has the capability to simulate these complex signals and provide the DC power and enable command to operate the unit for test and analysis. 4.2 QPSK Test Signals Two QPSK signals are stored as data files on disk, one having a low data rate representing the narrowest bandwidth signal that will be produced by the NIU in operation, and one having a high data rate representing the widest bandwidth signal that will be produced by the NIU in operation. Refer to Table 4-1 for these parameters.

Exhibit 12 Page 1 of 3FCC ID: NNSRTU2000-00 4/05/00 Exhibit 12 – Operational Description Customer Premises Equipment Roof Unit 2.0 FCC ID: NNSRTU2000-00 Model Number : RTU2000-28-3 Information Provided in this Exhibit: Operational description of CPE Roof Unit Exhibit 12 Page 2 of 3FCC ID: NNSRTU2000-00 4/05/00 Operational Description of CPE Roof Unit The SpectraPoint ® LMDS system is designed to transport a variety of broadband wireless services to customers. This LMDS system is capable of delivering up to 360 MHz of contiguous bandwidth of data services to customers in an area of up to 5 Km radius from a central base station. The same frequency spectrum may be reused in similar sectors throughout a given metropolitan area. The two basic parts that make up the SpectraPoint ® LMDS system are the Base Station and Subscriber Terminal equipment. The block diagram in Figure 1 shows the relationship of the Customer Premises Equipment (CPE) Roof Unit to the total system. In the diagram, the downstream direction is defined from the RF Transmitter to the Roof Unit. The reverse signal direction is defined as upstream. In operation, the DS3 data interface to the Channel Group is processed and then Quadrature Phase Shift Key (QPSK) modulated onto an L-Band Intermediate Frequency (IF) carrier. The IF is input to the RF Transmitter where it is upconverted to the 27.50 – 27.86 GHz within the authorized LMDS frequency band. The RF is transmitted downstream through one of 4 orthogonal sectors. Each sector reuses the same frequency spectrum analogous to a cellular phone system that has no moving components. ATM Switch Channel Group RF Transmitter Roof Top Unit Channel Group RF Transmitter Network Interface Customer Access Device Channel Group RF Receiver Subscriber Terminal DS3c Base Station Figure 1: LMDS Block Diagram Down Stream > > > < < < Up Stream The CPE roof unit serves as a transceiver at the customer premises location for the subscriber terminal equipment. The CPE roof unit receives a downstream carrier and down converts the RF signal from 27.50 – 27.86 GHz back to L-Band IF in the 1100 to 1460 MHz range. The L-Band QPSK modulated carrier is input to the Network Interface Unit (NIU) where it is demodulated into data streams to interface with customer T1, 10BaseT LAN, and digital video data equipment. In the upstream direction, the customer interface to the Network Interface Unit (NIU) is made up of T1 data lines, 10BaseT local area network data, or digital video data. The NIU combines the data into a single data stream and QPSK modulates the data on to an Exhibit 12 Page 3 of 3FCC ID: NNSRTU2000-00 4/05/00 L-Band IF carrier between 1590 – 1950 MHz. This IF carrier is then input to the transmit side of the CPE Roof Unit Transceiver. The CPE Roof Unit upconverts the L-Band signal to the 27.99 – 28.35 GHz within the authorized LMDS frequency band for transmission upstream to the RF Receiver. The RF Receiver then down converts the RF to the L-band frequency in a reverse of the Base Station downstream process. Finally data is reassembled into a DS3 ATM format for interfacing with the a network switch. Frequency stability of the CPE roof unit is maintained through high stability crystal based internal oscillator. Power to the CPE roof unit is supplied through the RF coaxial cable interface to the receiver IF connector. The CPE operates from 12 VDC nominal at a maximum current of 2.4 amps. A transmitter enable voltage of +5 VDC is supplied through the RF coaxial cable interface to the transmitter IF connector. The Roof Unit transmitter operates in a power control mode with power levels controlled through a closed loop with the Base Station. This loop senses signal strength variations due to changes in path parameters and adjusts power levels of the CPE roof unit transmitter. In case of total loss of the link, or oscillator not ready condition, the transmitter portion of the CPE Roof Unit will be disabled.
