TELECOMMUNICATIONS TECHNICAL MANUAL EXHIBIT III (PRELIMINARY) BTS-7010 WIRELESS MODEM TERMINATION SYSTEM (WMTS) REV: 0 102 Rahway Road McMurray, PA 15317 USA Phone 412-941-1500 FAX 412-941-9421 ADC SYSTEM DESCRIPTION The Wireless Modem Termination System is a hub modem system that accepts full duplex 100BaseT Ethernet, arranges the incoming Ethernet data frames, multiplexes in TDM and modulates a downstream 64 QAM carrier. The 64 QAM IF output (44 MHz) signal/s is fed to the RF input/s of the Base Transceiver Station (BTS). This manual covers both Upstream and Downstream information, however only the downstream components apply to this Type Acceptance submittal. The Downstream components include the following: • WMTS Chassis • Host Card • Universal Cards (x2) • Downstream Cards (x2) Each WMTS chassis supports up to two downstream channels; therefore four-channel operation requires two WMTS chassis and corresponding circuit board cards. © Vyyo 2000 All rights reserved. v.3.

Vyyo’s flexible point- to-multipoint systems are based on the Internet Protocol (IP) used for data and voice transport over the Internet, providing cost- effective and scalable solutions to support broadband wireless services. The V3000 Wireless Hub (WMTS) serves as a data communications bridge between Vyyo’s V251 Wireless Modems installed at the subscriber’s home or office and network backbone connections (routers) located at a central office or base station. The V3000 is a carrier class wireless system that features hot-swap modification or system module replacement by the operator while maintaining continuous operation. When used in combination with the V251 Wireless Modems, the wireless hub enables radio frequency (RF) performance in any of the currently licensed or unlicensed point-to-multipoint frequency bands. This is accomplished, in part, by permitting the system operator to establish upstream sub-channels and downstream channels with various combinations of modulation techniques. The wireless hub chassis supports multiple RF modules. Each module may be either an Upstream Demodulator (receiver) module or a Downstream Modulator (transmitter) module for the V251 series modems. The downstream modules are available in single channel versions. The upstream modules are available in single or hex (6) channel versions. This gives the system engineer the flexibility to configure a system for each deployment scenario using multiple channels or sub-channels, multiple sectors or a combination. DOCSIS Standard Adapted for Wireless Systems Vyyo’s systems employ an enhanced version of DOCSIS which was adapted for wireless environments from the cable industry’s DOCSIS standard. The specification is excellent in network and data link protocols, QoS, convergence, synchronization, registration, encryption, privacy, etc. However, because DOCSIS was designed for cable TV systems, it is inadequate to address some unique characteristics of the wireless environment, e.g., frequency offset and drift, dynamic range, spurious emissions, multipath and fading immunity. Vyyo’s wireless enhancements allow robust operation over the full spectrum, including licensed or unlicensed. A few of the specific wireless enhancements that are incorporated in the V251 Wireless Modem are: • Three types of downstream modulation (QPSK, 16QAM, and 64QAM) • Two types of upstream modulation (QPSK and 16QAM) • Multiple symbol rate options upstream and downstream • Frequency compensation for offset, drift over temperature and aging • Low spurious emissions and harmonics • Extended dynamic range • Robust power control These enhancements allow the V251 Wireless Modem to meet the requirements of the FCC and to provide robust performance in the RF path.

The WMTS provides full duplex 100BaseT Ethernet interface to the network. The WMTS arranges the incoming Ethernet data frames, multiplexes (TDM) and modulates the downstream carrier to produce a 64 QAM, 44 MHz IF output signal that feeds the input of the BTS-7010 Broadband Booster. The WMTS can support up to two downstream output channels per chassis. Single channel downstream operation requires the following cards: Host Card Two Universal Cards - Unpopulated Universal Card (automatically functions as Carrier and Forward Card) - Populated Universal Card (w/ Downstream Card) Downstream Card Power Supply Card (second power supply card may be added for redundancy) A second downstream channel may be added with the addition of a second Universal Card and Second Downstream Card. The input signal enters the system through a 100BaseT connector located on the front panel of the Carrier and Forward Card. This card manages the entire WMTS and runs an SNMP administrator management interface program. The signal is passed to the appropriate Downstream/Universal Card which sends the signal, still in digital format, to the Downstream Card. The Downstream Card converts the signal to the appropriate modulated format (64 QAM) and frequency (44 MHz). The Host Card provides bus arbitration, system clock and timing. A second Host Card may by added for redundancy. The Power Supply Card is an auto-ranging AC supply (90 – 264VRMS) from 47 – 63Hz. A second Power Supply Card may be added for redundancy. 2.0TECHNICAL DESCRIPTION 2.4 Circuit Description - continued Frequency Agile QAM Upconverter For complete description of QAM Upconverter see Exhibit IV (BTS-7010, Frequency Agile QAM Upconverter). The Wavecom MA4040D frequency agile upconverter is a fully agile IF upconverter designed for cable, MMDS and LMDS applications. The MA4040D is a modular circuit card designed to be used in a MA4002D card chassis with up to 10 independent MA4040D frequency agile upconverters. The cards are powered with a common MA4011D power/control module. The MA4040D upconverts a 44 MHz IF input signal to any selectable 6 MHz channel from 53 to 857 MHz. Front panel push buttons are used to select the output frequency which is variable in 12.5 KHz steps. Using advanced design, the MA4040D maintains a phase noise specification that exceeds the DOCSIS requirements for 64/256 QAM. Low out of band noise performance and low spurious are achieved through high level mixing, a microwave frequency IF and multiple levels of filtering. The MA4040D uses an automatic IF AGC circuit to correct for input level changes and provides a high level output of +61 dBmV. Local oscillators are frequency synthesized and locked to a common internal high stability reference. The Power/Control Module contains a auto ranging switching power supply that operates from 100 to 240 VAC and local control via an LCD and 4 soft touch push buttons. AN RF Output port, RF Sample Port and IF Input port are located on the rear of the card. 2.0TECHNICAL DESCRIPTION 2.4 Circuit Description - continued Broadband Booster The BTS-7010 is a complete MDS/MMDS/ITFS multi-channel booster capable of operating as digital television/data transmitter in a N+1 redundant configuration. The unit is comprised of four main transmitters or Sectors and a back-up Sector. Each transmitter sector is comprised of a Multiplexer Assembly, , Upconverter Assembly, Power Amplifier Assembly, Bandpass Filter Assembly and Downstream Controller Assembly. The Back-up sector is comprised of a Downstream Switch Assembly, Back-up Upconverter Assembly, Back-up Amplifier Assembly, and Transfer Switch Assembly. Back-up operation is directed and controlled by the Automatic Back-up System (ABS) Controller Assembly. System Monitoring is provided by the System Monitoring Assembly and a reference frequency is provided by the 10 MHz Reference Assembly. Power to the system is provided by the Power Supply Assembly. The Power Supply Assembly is a dual output supply capable of operating in a redundant N+1, hot swap application with a second or third supply. Each of the Assemblies are described in detail below. Multiplexer Assembly The 6MHz wide, 222 to 408 MHz IF output signal from the MA4040D Frequency Agile Upconverter is applied to one of four IF input jacks (J211, J212, J213, J214) on the rear of the BTS1.0 transmitter. These four jacks provide the inputs to each of the four transmitter sectors of the BTS1.0. Each of the four sectors are identical in design and function and therefore only one will be described. This IF input signal is then fed to the Multiplexer Assembly (1113588) at Jack J1 pin 22. The IF (222-408 MHz) signal is filtered then split into two signals by IC splitter U1. One output (J34-11) is fed to the Downstream Switch in the back-up section of the unit. The main output (J34-5) is fed to the Upconverter Assembly. Upconverter Assembly The IF input from the Multiplexer is applied to the Upconverter at J4 and can range fro…

ADC TELECOMMUNICATIONS EXHIBIT X ALIGNMENT PROCEDURE 2.0TECHNICAL DESCRIPTION 2.5 Alignment Procedure In the following procedure, the complete transmitter is adjusted for optimum performance, beginning with the start up procedure of the QAM modulator, followed by the QAM agile upconverter, then the digital transmitter, starting at the base band input and adjusting each circuit for its specified performance while observing the appropriate output parameters of the board or subassembly being adjusted. Because of the broadband nature of most of the amplifier stages, this is a straightforward procedure, easily accomplished if base band, IF, and RF test equipment is available. In this procedure, the input signals are first connected and each circuit is adjusted in sequence by connecting the test equipment to the specified point. Equipment Needed Spectrum Analyzer RF Power Meter 30 dB Directional Coupler 10 dB Directional Coupler Volt Meter 50Ω Load Adjust the spectrum analyzer for the following settings: 1. Resolution BW = 30 KHz 2. Video Averaging (ON) 3. Span = 20 MHz 4. Video Bandwidth = 30 kHz 5. Center Frequency = 44 MHz The average power of a modulated QAM digital signal, with the specified analyzer settings, is +23dB higher than the displayed signal. The measurements in this alignment procedure will be given in average levels. Example: Analyzer reading of –30 dBm Average power = -30 dBm + 23 dBm = - 7 dBm. 2.0TECHNICAL DESCRIPTION 2.5 Alignment Procedure - continued WMTS (QAM MODULATOR TRAY) Follow the steps listed in Sections 2.2.1 and 2.2.2 of Exhibit III to bring the WMTS modulator online.
