Part 2 of 2 Issue 2, June, 2004 Microwave Digital Radios Users Manual 4-1 4 INITIAL TURNUP 4.1 SECTION INTRODUCTION This section describes the procedures required to turn up the MDR-8000 Microwave Digital Radios after installation. This provisioning part of the section describes provisioning options available with the MDR-8000 software application. Provisioning allows for the definition, editing, and storing of specific functions. The MDR-8000 provides the ability to provision equipment and facili- ties through a series of Windows™-based screens and messages. The Provisioning menu lists equipment and functions which may be provisioned. You should use only those provi- sioning screens that are applicable to your radio. Refer to the Users Guide section and applicable DS1/E1, DS3, or OC3 Initial Turnup section on the attached CD for more infor- mation. 4.2 RECOMMENDED SEQUENCE Perform the following initial turnup procedures in sequence: 1 Install software on PC. Software installed at the factory before delivery should not be overwrit- ten by downloading to the radio controller at initial turnup. Refer to Maintenance section on the attached CD for procedure to upgrade exist- ing software. 2 Establish communication between radio and USI computer. Saving provisioning on disk provides a reference for any future provi- sioning changes. 3 Provision radio. See Figure 4-1. The radio has been properly aligned and tested at the factory before shipment eliminating the need for testing after initial turn-up. The only time testing and/or adjustment is required is after a maintenance action such as removal and replacement procedure and/or constant alarms requiring corrective maintenance action. The completed maintenance action procedure(s) will reference any required test procedure(s).

EXHIBIT 9. MDR–8000 Operational Description In the transmit direction the MDR–8000 uses a modulation structure where the I and Q baseband signals modulate the in–phase and quadrature phase components of the transmitter. The DS1/E1 I/O interface converts the format of the incoming DS1/E1 data streams to I, Q, data, and clock. The DS1/E1 I/O interface module uses the DS1/E1 signals to generate 32 or 128 trellis code amplitude modulated (TCM) baseband signals The transmitter processes the TCM baseband signals to generate the modulated TCM RF signal. The RF signal is then amplified and applied directly to the antenna branching or further amplified by a solid–state amplifier (optional) and applied to the antenna branching. In the receive direction, the MDR–8000 uses a demodulation conversion structure. The received TCM RF signal is fed into a filter followed by a receiver module. The receiver module directly converts the RF signal to I and Q baseband signals and provides all of the acquisition loops. The receiver also provides countermeasures to dynamic path distortions. Clock and digital data are extracted from the analog channels and passed on to the I/O interface. The digital data is processed by the I/O interface module and converted to a DS1/E1 format. WCS development requirements: Four components need to be developed: Transmitter Receiver Power Amplifier RF filters. The Transmitter, Receiver and Power Amplifier are all modified versions of the PCS band modules. The 6 MHz bandwidth filter is intended for use at sites where other microwave transmitters are co-located and operate at frequencies very close to the MDR-8X02 receiver operating frequency. The filter is designed to provide at least 30 dB of rejection 7 MHz away from the operating frequency. Transmitter: • The main development of the Transmitter is to improve the out-of-band noise floor. • One goal is to increase the frequency flexibility of the current 2GHz Transmitter to accommodate the WCS application. • The transmitter design is based on a phase locked VCO which is a stepping stone to a synthesized transmitter in the future. • The requirements are as follows: • T/L PN: 3EM11962ADAA • PB/RF: 3EM11960ACAA • PBA/RF: 3EM11961ADA • BB ASSY: 3DH03139 • Frequency range: 2305 – 2360 MHz (WCS Band) • RF DC requirements: +/- 5 VDC, +10.5 VDC, +/- 12 VDC • Interface requirement: • Baseband interface: 20 pin, thru hole male connector • I/Q inputs:------- -10dBm • RF detect:------ 500mV +/- 50mV • DC:-------------- +10.5 +/- .2 VDC +5 +/- .1 VDC -5 +/- .1 VDC +12 +/- .2 VDC -12 +/- .2 VDC • Freq Ctrl---------- +3.0 VDC • VVA control------ 0 to 3 VDC • LO interface: 10 pin ribbon connector • LO level: --------- +10 dBm +/- 2 dB • LO monitor: BNC connector • LO level: --------- -10 dBm +/- 2 dB • RF monitor: SMA connector • Level: -------------- 0 dBm +/- 2 dB • RF monitor: SMA connector • Level: ------------- +18 dBm Receivers: • The Receiver effort will be an effort to maximize T/I performance, modifying some baseband filtering and optimizing gain/linearity of the design. The design is based on a phase locked VCO. As with the transmitter, receiver frequency flexibility is required. • The requirements are as follows: • T/L PN: 3EM11964AAAA • PB/RF: 3EM11963ACAA • PBA/RF: 3EM11964ADAA • BB ASSY: 3DH03134AKAH • Frequency range: 2305 – 2360 MHz (WCS Band) • RF DC requirements: +/- 5 VDC, +/- 12 VDC • Interface requirement: • Baseband interface: 20 pin, thru hole male connector • DC:--------------- +5 +/- .1 VDC -5 +/- .1 VDC +12 +/- .2 VDC -12 +/- .2 VDC • Freq Ctrl---------- +3.0 VDC • AFC -------------- 0 to 3 VDC • LO interface: 10 pin ribbon connector • LO level: --------- +10 dBm +/- 2 dB • LO monitor: BNC connector • LO level: --------- -10 dBm +/- 2 dB • RF input: SMA connector • Input Level: ---- -15 to -92 dBm • RF Gain: ----------28 dB max. • NF: -------------- 2.8 dB max.

For operation in the C and D blocks of the WCS band it was necessary to reduce the transmit power by 1 dB due to the increase insertion loss of the 6 MHz narrow band filter. 4. The maximum rated RF power as submitted in FCC Form 731 is 2 Watts MDR-8702-16 Private/Common Carrier Digital Radio Radio Characteristics FCC Identification JF6-8702-8 Frequency Range 2.305-2317.6 GHz and 2347.5-2.360 GHz RF Channel Bandwidth 5.00 MHz Occupied Bandwidth 2.1768 MHz Emission Designation 2M50D7W Modulation Type 128 TCM Data Range 12.62 Mb/s Baud Rate 2.02 Mbaud/s Data Efficiency 6.25 bits/Hz Transmit Power +33 dBm (2 Watts) Transmit Frequency Stability 0.005 % (-20 to +50 Degrees C.) Primary Voltage Range 24 – 48 Vdc (positive or negative) Operating Temperature Range 0 to 50 Degrees C Attached Support Documents Equipment Photograph FCCID Label Drawing Defining location of FCCID label 2.984 RF Power Output 2.985 Modulation Characteristics 2.986 Occupied Bandwidth 2.987 Emissions at Antenna Port 2.988 Field Strength of Spurious Radiation 2.989 Frequency Stability 2.990 RF POWER OUTPUT Power output is measured and set at the RF antenna port of the transmitter using an HP 436A Power Meter with an HP 8481 B High Power sensor. The transmit power is set at the desired level by adjusting the Power Amplifier GAIN ADJ at the front of this module. The Power Amplifier has the following characteristics: Alcatel Part Number: 3EM 09037 ADAA Type Design: Solid State DC Power Requirement: +10.5 VDC @ 7.3A -12 VDC @ 100 mA -5 VDC @ 100 mA Gain: 25 dB typical Output Power: +33 dBm transmit power at the RF antenna 2.991 MODULATION CHARACTERISTICS The modulation employed in this equipment is 128 and 32 TCM (Trellis Coded Modulation). This modulation was selected to achieve good BER (bit error rate) performance while maintaining …
