User guide NTXXXXXX Rel 3.0 Draft October 20001-1System description 1-This document describes the Internet BWA System 3200. OverviewThe Internet BWA System 3200 establishes high-speed, reliable point-to-point wireless links. The Internet BWA System 3200 uses a 4-FSK modulation scheme and carries up to four E1 (2.048 Mbits/s) or up to four DS1 (1.544 Mbits/s) signals.Frequency bandThe Internet BWA System 3200 operates in the 15, 18, 23, 24/26, 28, 31 and 38 GHz frequency ranges. CapacityThe capacity upgrade is software programmable from 2xE1 to 4xE1 and from 1xDS1 to 2xDS1 to 4xDS1. The capacity upgrade affects traffic because the upgrade changes the following parameters:• occupied bandwidth• receive baseband filters• data rate of operationTable 1-1 lists the bandwidths for the radio frequency (RF) channels.Table 1-1RF channel bandwidthsCapacity Channel bandwidth (MHz)2 x E1 3.5 (for all frequencies)4 x E1 7.0 (for all frequencies)1 or 2 x DS1 2.5 (for all frequencies)4 x DS1 5.0 (for all frequencies)
1-2 System descriptionInternet BWA System 3200 NTXXXXXX Rel 3.0 Draft October 2000For systems with a specific capacity (for example, a 4 x E1 capacity), the activation of a new tributary within that capacity is software programmable, either locally or remotely. The activation of a new tributary within an existing capacity does not cause any errors to the existing traffic. Inactive tributaries do not cause alarms. Frequency planFrequency plans are in accordance with:• current ITU-R recommendations and annexes as applicable for international products• FCC rules, part 101 (as amended on October 1, 1997, replaces parts 21 and 94)• Industry Canada (SRSP-314.5, SRSP-318.5, SRSP-321.8) for North American productsTable 1-2 lists the frequency plans.System featuresThe Internet BWA System 3200 provides:• scalable channel capacity to precisely match traffic volume• scalable channel selection (digital synthesizer set in 250 kHz steps)• selectable AMI or B8ZS line coding for DS1 signals (E1 signals use HDB3 coding only)• selectable framing type (Unframe, Frame or ESF for DS1 signals)• hand-held wireless terminal to perform configuration, maintenance, and performance monitoring of the outdoor unit (ODU)• receive signal strength indicator (RSSI) on the outdoor unit to guide service personnel in antenna alignment• forward error correction (FEC) and link ID codes• common ODU and frequency synthesizer to minimize the number of spare units and cost• simple installation and maintenance from the “twist and lock” design of the outdoor unit.Table 1-2Frequency plansFrequency band 15 GHz 18 GHz 23 GHz 24/26 GHz 28/29 GHz 31 GHz 38 GHzFrequency range (MHz) 14.4- 15.35 17.7- 19.7 21.2- 23.6 24.25- 26.5 27.5- 29.5 31.0- 31.3 37.0- 40.0
System description 1-3User guide NTXXXXXX Rel 3.0 Draft October 2000Equipment layout and main assembliesThe Internet BWA System 3200 includes an outdoor unit (ODU), an antenna and a mounting assembly (see Figure 1-1). A terminal site requires one Internet BWA System 3200 to handle the radio signals for both the east and west directions. Figure 1-1Internet BWA System 3200—physical layoutMOP0082t.epsOutdoor unitThe outdoor unit contains a Modem, an RF module, a power supply and a remote communication link. Removal of the outdoor unit is possible without the need to realign the antenna. Mounting assemblyThe Internet BWA System 3200 includes a mounting assembly to hold the radio to a pipe mount. The mounting assembly design provides three 30° elevation adjustment increments for a 90° elevation adjustment range. The mounting assembly design also provides two 45° azimuth adjustment increments for a 90° azimut adjustment range. MountingassemblyInterface cableassemblyOutdoor unitAntenna

Figure 1-2 shows a block diagram of the Internet BWA System 3200 components.Figure 1-2Internet BWA System 3200 components—block diagramF6357p.epsTransmit signal pathThe transmitter side of the RF module consists of a frequency modulated source at the T/R spacing frequency of 1260 MHz. The output of the frequency-modulated source is then upconverted to an X-Band frequency by a local oscillator that can be set for low side or high side injection. Next the RF signal is multiplied to a frequency within the operating band of 37.0 to 39.5 GHz. Harmonic mixing using a local oscillator (LO), at half the output transmit frequency, down-converts the incoming remote site RF input signal to an IF of 1260 MHz. Internal RF frequency settings will determine if the RF input signal frequency is above or below the transmitter RF frequency. NRZ baseband modulation is imparted on and recovered from the 38 GHz carrier via a proprietary scheme that permits using a single multi-channel frequency synthesizer.MicroprocessorControl,TemperatureandMonitor FunctionSynthesizerandLockDetectorModulationFilter, Gainand D/AUpconverterChainFMModulatedSourceMultiplierOutputPowerDetectorPowerControland MuteModulationRemovalI/QBasebandGain Adjustand A/D'sReceiverMixerandIF LNAIF AGC,IF FiltersandIF DetectorIntegratedParabolicAntennaModemDSPFunctionsBattery (-)Battery (+)Tx DataTwisted pairRx DataTwisted pairRS485 ARS485 BSummary Alm(NC/NO)CableInterfaceBNC InterfaceAGC voltage& Coaxial I/Oor Wirelesslink I/OTwisted pair120 Ohm
System description 1-5User guide NTXXXXXX Rel 3.0 Draft October 2000Receive signal pathAn analog AGC voltage is applied in the IF circuitry under microprocessor control to reduce the dynamic range of the A/D input signal. Both broadband and narrow-band detection is employed. Broadband detection is analog detection at 1.26 GHz. Narrow-band detection is within the DSP. This design enables the receiver to cope with large adjacent channel signal levels and provides excellent A/D dynamic range to recover the desired signal.System interfacesFigure 1-2 shows the interfaces on the outdoor unit (ODU).Figure 1-3Outdoor unit interfacesF6358p.epsPort for coaxial I/O andwireless link I/OInterfacecablepinsGroundconnectionMountingscrew(4 places)Top ViewBottom ViewPolarization indicator(2 places)

Testing the Radio faultsThe Internet BWA System 3200 has three types of loopback tests for fault isolation.RF Loopback testThis loopback retunes the receiver to the transmit frequency. RF leakage through the diplexer assembly prompts the local receiver to synchronize with the local transmitter. This loopback test provides an unambiguous check of all active circuitry in the Internet BWA System 3200.Unwanted emissions are squelched by the transmit diplexer (out-of-band of the RF bandpass filter). This loopback test is used for troubleshooting purposes. To use this function, refer to Chapter 5, “User interface description”. Loopback test for the local tributaryLoops the tributary input (data from customer) back onto tributary output (data to customer) at local terminal. This test checks connection to the customer equipment. To use this function, refer to Chapter 5, “User interface description”.Loopback test for the remote tributaryLoops the remote tributary output (data to customer) back into remote tributary input. This test checks the radio link operation. This loopback test does not include the remote tributary line driver or the remote tributary line receiver. To use this function, refer to Chapter 5, “User interface description”.

The HHT gives access to a series of menus with provisioning, monitoring, control, maintenance and query commands for the Internet BWA System 3200. • The HHT remains active until the user logs off or the HHT loses communication with the Internet BWA System 3200. • When viewing or setting parameters, the HHT powers down 60 seconds after the last entry. • Under normal operating conditions, normal battery life is 25 hours with the use of industrial-grade alkaline cells, .• The HHT can lock up when the batteries are weak or not correctly installed. If the HHT locks up, remove and insert the batteries again.
5-2 User interface descriptionInternet BWA System 3200 NTXXXXXX Rel 3.0 Draft October 2000• If you enter incorrect data, “Invalid Value” appears on the LCD. The circuit is usually in a muted state. The channel opens when the HHT issues a command. The HHT can communicate to the ODU of the Internet BWA System 3200 with the use of either:• a wireless channel (418 MHz or 433.92 MHz channel with the use the of whip antennas on the ODU and on the HHT)• a coaxial cable (RG-58U cable) that connects between the ODU and the HHTRefer to Figure 1-3 on page 1-5 for the location of the wireless link or coaxial I/O port.
