Imotwcnou
The Ttacer provides dual Tl transport by way ola spread spectrum
microwave link for distances up to 20 miles or more depending
on path engineering, System performance is determined, in part,
by the engineering of the microwave link, Each end of a Tracer
link is composed of two units —- the baseband processor (BB?)
and the radio frequency converter (RFC). Two DSl/DSX-l (T1)
interfaces are provided on the rear of the BBR which can be
mounted in a 19" rack. The DSl/DSX- 1 interface provides
connections up to 6000 feet from T1 equipment. A single coaxial“
cable connects the 58? to the RFC and another connects the RFC R
to the antenna
ISM an Spam Specnwu
l/Zl mug-nun
The Federal Communications Commission (FCC) has established g
several portions of the radio frequency (RF) spectrum for use inm
Industrial Scientific and Medical (ISM) applications Part 15. 247
of the FCC rules describes the requirements of systems that operate
in these bands. The three bands set aside. 902~928 MHz.
HOG-2483.5 MHz, and 5725-5850 MHz, are designated for use
by spread spectrum transmitters, either frequency hopping or
direct sequence. The Tracer operates in the 2400 to 2483.5 MHz
hand using direct sequence spread spectrum (DSSS) transmission.

Figure 1-1. Typical Application
The Tracer can be used in any application requiring that data be
shared at a high rate of speed. In addition to telephony
applications. Tracer can be used in data communications such as
inter-networking, video conferencing, and telemetry
Sum Sncmuu
Spread spectrum is a form of communication in which the
bandwidth of a message signal is intentionally increased or
“spread." The FCC rules allow two methods of spreading --
frequency hopping and direct sequence. Tracer employs direct
sequence spread spectrum.
PAGE 3
CHANNEL SELECTION
TRluR Drscmwmn
Dutrcr SequeNce
A direct sequence transmitter spreads the signal by mixing the
data with the output of a pseudorandom number generator which
changes state at a rate higher than the data rate. This rate is called
the “chipping" rate. The Tracer chipping rate is twelve times the
data rate.
Comma
Many different pseudarandom sequences exist. The sequences
are called pseudorandom because, although they appear noise-
like, they are determinant and repeat alter a specific number of
chips. The longer a code is, the better correlation characteristics
it possesses. These traits allow multiple spread spectrum systems
to operate in the presence of one another With minim] interference
if they are operating with different sequences, The Tracer allows
the selection of one of ten different lZO-bit long sequences.
uituilajd
The FCC has allocated 83.5 MHz of spectrum in the band in which °‘
the Tracer operatesr A Tracer system fully uses the available _
bandwidth -- transmitting in one half and receiving in the other. __
The figure below illustrates the bandwidth division.

Section I
The transmitter at one end (TxA) oi a link wtll transmit in the
lower half of the spectrum. Consequently the receiver at the other
end will receive in the lower half of the band and transmit in the
upper hallr Thus, a system will operate in one ol two frequency
plans -- transmit in the upper and receive in the lower or vice
versa. These two plans are called Plan A and Plan B. One end of
a path will be on Plan A and the other wrllbe on Plan B, Shipment
of a link will consist of an A and a B unless specified otherwise.
Fotrwmn Ennon Connecmm
With the addition of overhead data. error detection and correction
capability can be added to a data stream. Error correction can be
accomplished by allowing the receiver to request the re-
transmission ol‘ an errored block once detected. The Tracer, on
the other hand, implements forward error correction (FEC) which
adds enough overhead data for the receiver to detect and correct
errors in the data stream. This capability comes at the cost of
bandwidth. The addition of FEC decreases the required signal-
to-noise (SIN) ratio by approximately 5.5 dB to achieve a given
bit error rate (BER).
T1 Omanuu
quc
The data in a Tl stream is delimited by framing bits. The pattern
of the framing bits follows one of two formats -- extended
superframe (ESF) or superlrame (SF), The T1 interface must be
prepared [or the format that will be used.
means
A mark in the data stream is coded as a pulse on the T1 line. A
space is coded as “no activity“ on the T1 line As a form of error
detection, subsequent marks in the data stream are coded as pulses
of alternating polarity, either positive going or negative going. This
type of line coding is called alternate mark inversion (AMI),
PAGE 5
Tmcfl't Dtscmvnm
For the Ti receiver to operate correctly. a minimum number of
"ls" must exist on the T1 facility. If the data cannot be guaranteed
to meet this requirement, then another line coding format is used.
In the bipolar8 zero substitution (13825) scheme, a string ofetght
“Os" is replaced by a special sequence of eight bits that contains a
bipolar violation. The receiver, upon recognizing this sequence,
reinsers the eight “0s" and the data is recovered intact.

Figure 1-3. RFC Module
The RFC is partitioned, functionally, into two major components
-- the transmitter and the receiver. It is partitioned physically into
three printed circuit boards,
The major connections illustrated are the transmit signal, receive
signal, and the lF signal connection.
The three SMA connectors located on the RFC module provide
the transmitted RF. received RF, and [F connection points, Two
test points are provided [or monitoring the received signal strength

This signal is used to align the antenna during installation and to
verify that the link is performing as designed. A third test point is
pronded to monitor the transmitter output power during system
configuration.
The only connections that must be made in the field are a coax
connection between the BB? and the RFC and a coax connection
between the RFC and the antenna
The “IF" connector provides the connection between the BB? and
the rack or mast-mounted RFC. (A blue 6-inch IF cable [ADTRAN
part number 3125.001@AI is provided for rack-mount systems.
ADTRAN does not provide IF cable for mast-mount systems.) The

Tracer is intended to be coupled with an antenna that is directional m
and provides signal gain. There are several reasons for this
requirement:
- Tracer operates in painblo-poinl applications: therefore, an
omnidirectional antenna is not needed.
- The FCC provides no recourse in this band in the event of nearby
interference, so a highly directional antenna reduces the
likelihood of interference in the antenna pattern.

gain antenna [or long links.

this operation. Attach an RF power meter to the N-type antenna
connector on the RFC, and adjust the power by way of the
potentiometer or VT-lOO until the desired transmitter power ts
obtained For convenience, the transmitter power adjustment
should be made before the RFC is installed on the mast.
Szmne m: RFC Fnrqvmcv PLAN
The frequency plan designates on which frequencies the Tracer
transmits and receives. Plan A corresponds to a transmitting (Tx)
frequency of 2422 MHz and a receive (Rx) frequency of 2462 MHz.
Plan B corresponds to a Tx frequency of 2462 MHz and a Rx
frequency of 2422 MHz. Shipment ofa link consists of one RFC
set to Plan A and the Other set to Plan 5 unless specified otherwise.
The RFC plan can, however. be changed in the field if required.
This procedure involves two steps:
- Configuring the RFC interconnect
- lnlorming the EBP of the correct Plan
To reconfigure the RFC interconnect. do the following:
1. Remove the [our screws which retain the RFC cover and remove
the cover.
fiG/BI/Zl Kmututnud
2. The RF unit may be identified by following the connection from
the port labelled “lF” on the rear of the RFC. This connection
