Srcnm. 1 TRACER Descmlmouv 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. Preliminary 12/18/98 Pro: 2 Simon 1 Armcmons Any application that would typically use metallic T1 as a transport can use the Tracer instead. The figure below illustrates a typical application. men nip-band Peon-slur mum-noun; w. mt unto angular! PM. .. Hut and he): nun: arc; my a. muted ma ices-mane individual sys 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. ”A1 86/8 2400 MHZ 244! MN: 2483.5 MHz Figure 1-2. Bandwidth Division Preliminary 12/ 18/98 Past 4 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. 081 /DSX-1 Imeltme When connecting the interface to the public sWitched network, an ADTRAN-provicled cross-over cable (part number 3125.M011@A) is required to meet FCC part 68 and 1C C503 requirements This cable is required to cross-over the Tx and Rx pairs to meet the connecting arrangement of a network interface device. This cable is included with the BB? and is labelled “Tl Ctossoverf' lJNE Bnmur on LBO tmuud The DSl/DSX 1 interface provides two different types of line- buildouts (LBOs) respectiver When set for D51, LBOs for 0 dB —7. 5 dB -15 dB and -22 dB are available.

Au“ Connors Two sets of alarm contacts are provided on the rear of the BBP: major alarm and minor alarm, A major alarm indicates the radio link is not operational. A minor alarm indicates that system performance is degraded or that the Tl interfaces are experiencing errors Normally-open and Normallyvclosed contacts are provided for both alarm typs. Under normal operating conditions there is no continuity between the Normally-open and Common contacts, and, under an alarm condition. continuity between those contacts exists. The Normally-closed and Common contacts normally have continuity. while under alarm conditions. these contacts are open.

GND Rum Fneoumcv CONVERTER on RFC The radio frequency converter or RFC (ADTRAN part number 1280.005Ll) provides the RF interface between the BBP and the antenna. The RFC module is illustrated in the figure below. 86/81/21 brutmllud 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 indicator or R551. The volmge (relative to the GND test point) present on this test point represents the level of the received signal, Pm; 12 Stet-rm I 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 “ANTENNA" connector proVides the connection between the RFC and the antenna. A block diagram of the RFC functions is shown in the figure below.

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. ~ The low power transmitter is intended to be used with a high- gain antenna [or long links.
