This document describes the Internet BWA System 3200.
Overview
The 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 band
The Internet BWA System 3200 operates in the 15, 18, 23, 24/26, 28, 31 and
38 GHz frequency ranges.
Capacity
The 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 operation
Table 1-1 lists the bandwidths for the radio frequency (RF) channels.
Table 1-1

User guide NTXXXXXX Rel 3.0 Draft October 2000
1-2 System description
For 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 plan
Frequency 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

The 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.

System description 1-3
Equipment layout and main assemblies
The 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.

Outdoor unit
The 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 assembly
The 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.

Transmit signal path
The 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.
Internet BWA System 3200
NTXXXXXX Rel 3.0 Draft October 2000
System description 1-5
Receive signal path
An 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.

Trouble clearing procedures
4-
This chapter contains information for fault locating, testing, and clearing
alarms for the Internet BWA System 3200.
Testing the Radio faults
The Internet BWA System 3200 has three types of loopback tests for fault
isolation.
RF Loopback test
This 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 tributary
Loops 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 tributary
Loops 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”.

This chapter describes how to use wireless hand-held terminal (HHT). The
HHT operates on batteries and allows quick and easy monitoring and changes
to the system parameters of the Internet BWA System 3200.
Hand-held terminal description
The HHT can operate within 75 meters (225 feet) of the ODU. The LCD
display provides visual access to a series of system software menus and
parameters on two lines of 16 characters each.
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.
User guide NTXXXXXX Rel 3.0 Draft October 2000
5-2 User interface description
• 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
HHT
Refer to Figure 1-3 on page 1-5 for the location of the wireless link or coaxial
I/O port.

Procedure 6-3
Connecting the interface cables
Use this procedure to connect all interface cables to the ODU of the Internet
BWA System 3200 .
DANGER
Risk of personal injury
Incorrect or unsafe installation can result in personal injury
The interface between all user equipment and the Internet BWA System 3200
is a 100-Ohm (DS1) or 120-Ohm (E1) twisted-pair cable assembly. The
twisted-pair cable assembly provides conductors for:
• alarm telemetry information
• programmable alarms
• the RS-485 communication link
• DC power source
• transmit and receive data lines (tributaries)
The cable has a drain wire and color-coded solid conductors of 24 AWG. The
bundled pairs are wrapped in a foil shield with internal drain wire and covered
with a wire braid and insulating jacket. The outer braid and drain wire
terminate at pin 1.
Requirements
Before you begin this procedure:
• Route the customer cables to an appropriate customer interface point (for
example, a cross-connect panel).
Note: For continued compliance with applicable regulatory requirements,
the DS1/E1 lines of the system cannot directly connect to a DS1/E1
network. They must connect only behind registered terminal equipment.

Additional guidelines before the connection of the interface cable:
— When cutting the cable length, be sure to add extra length for the
service loop.
— Ensure that a strain relief is added to each cable connection.
— Ensure that the external connector is sealed and waterproof.
— Follow standard installation practices.
– Avoid sharp corners.
– Attach the interface cable to the tower members or cable runways
with the use of hanger kits or tie-wraps at one meter intervals.
— When routing the interface cable, avoid blocking the wireless antenna
pattern.

Action
If you connect less than 4 DS1 channels or less than 4 E1 channels, insulate
the ends of the unused twisted pairs with electrical tape. Then label and
fasten the ends for future identification.
CAUTION
Reduced system performance
Failure to use the correct cable types significantly
reduces system performance.
Connect the female end of the interface cable to the 31-pin male connector
on the ODU (align the connector guide pins and rotate to set the cable in
place and do not force the cable connector into the ODU connector).
Attach the wireless link antenna
Remove the 433.92-MHz antenna with reverse SMA connector from the
accessory kit.
