61280.003L1-1B PAGE 1 SECTION 1 TRACER DESCRIPTION INTRODUCTION The Tracer provides dual T1 transport by way of a 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 (BBP) and the radio frequency converter (RFC).
PAGE 2 SECTION 1 61280.003L1-1B APPLICATIONS Any application that would typically use metallic T1 as a transport can use the Tracer instead. The figure below illustrates a typical application.
61280.003L1-1B PAGE 3 TRACER DESCRIPTION DIRECT 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. CODING Many different pseudorandom sequences exist.
PAGE 4 SECTION 1 61280.003L1-1B The transmitter at one end (TxA) of a link will 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 half. Thus, a system will operate in one of 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 will be on Plan B.
61280.003L1-1B PAGE 5 TRACER DESCRIPTION For the T1 receiver to operate correctly, a minimum number of “1s” 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 bipolar 8 zero substitution (B8ZS) scheme, a string of eight “0s” is replaced by a special sequence of eight bits that contains a bipolar violation. The receiver, upon recognizing this sequence, reinserts the eight “0s” and the data is recovered intact.
PAGE 6 SECTION 1 61280.003L1-1B Tracer SYSTEM CONFIGURATION A Tracer system is composed of three major subsystems -- a baseband processor, a radio frequency convertor, and an antenna. The following section describes the system components. BASEBAND PROCESSOR OR BBP The BBP (ADTRAN part number 1280.003L1) is a 1-U, 19" rackmountable unit that provides the system electrical interfaces, user controls and indicators, and performs the spread spectrum processing for the system.
61280.003L1-1B PAGE 7 TRACER DESCRIPTION The interfaces are illustrated in the BBP Block Diagram below. The functions of the BBP are partitioned into three printed circuit boards or PCBs, all contained in the same enclosure. RS-232 UART T1A T1 Baseband Processor Board µC T1C Multiplex T1B Spread Spectrum Data Pump Viterbi Encoder/ Decoder T1 Fc = 140 MHz IF Filter Σ DSP 90 Fc = 70 MHz 90 IF Interface Board -48Vdc Figure 1-5.
PAGE 8 SECTION 1 61280.003L1-1B For connections to other CPE-type equipment, such as an ADTRAN TSU-100, a straight-through T1 cable is provided by ADTRAN (part number 3127.004) and is included with the BBP. VT-100 RS-232 INTERFACE A serial interface port using RS-232C signal levels is provided for attaching a VT-100-compatible terminal. The connection is made via a DB-25 connector on the rear panel. The data rate is configured for 9600 bps, 8 data bits, no parity, and 1 stop bit.
61280.003L1-1B PAGE 9 TRACER DESCRIPTION AC/DC POWER The unit receives power via one of two connectors. Power for the entire system is provided by these interfaces. The three-pin circular DIN connector is provided to connect an optional ADTRAN desktop AC adapter (ADTRAN part number 1360.DSK24VL1), providing 24 volts DC. The three-pin terminal block allows the connection of any DC power source providing between 21 and 56 volts DC. The power consumption of the entire system is 30 watts.
PAGE 10 SECTION 1 61280.003L1-1B The LEDs associated with the DS1/DSX-1 interfaces are listed below. There are two sections of identical indicators -- one for each DS1/DSX-1 interface. BPV .............. Red if the incoming T1 stream contains bipolar violations RED ............. Red if there is no signal present at the T1 interface LPBK ............ Yellow if the T1 interface is in loopback YEL/AIS .......

PAGE 12 SECTION 1 61280.003L1-1B 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 provided 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 BBP and the RFC and a coax connection between the RFC and the antenna. The “IF” connector provides the connection between the BBP and the rack or mast-mounted RFC.

61280.003L1-1B PAGE 15 SECTION 2 INSTALLATION RADIO FREQUENCY INTERFERENCE STATEMENT This equipment has been tested and found to comply with the limits for an intentional radiator, pursuant to Part 15, Subpart C of the FCC Rules. This equipment generates, uses, and can radiate radio frequency energy. If not installed and used in accordance with the instructions, it may cause interference to radio communications.
PAGE 16 61280.003L1-1B SECTION 2 FCC OUTPUT POWER RESTRICTIONS The FCC does not require licensing to implement this device. However, the FCC has established restrictions regarding maximum output power and the adjustments required when employing directional gain antennae. (Refer to “Setting the Transmitter Power” in Section 2 of this manual). These restrictions are detailed in FCC Part 15.247 (b)(1), (b)(3)(i), and (3)(iii).
61280.003L1-1B PAGE 17 INSTALLATION UNPACK, INSPECT Carefully inspect the Tracer for any shipping damages. If damage is suspected, file a claim immediately with the carrier then contact ADTRAN Customer Service. If possible, keep the original shipping container for use in shipping the Tracer back for repair or for verification of damage during shipment. Before beginning installation, verify that all of the following components are present.
PAGE 18 61280.003L1-1B SECTION 2 INSTALLATION LOCATION Install the Tracer in a location that requires minimal antenna feedline length (the loss in this cable directly affects overall system performance). When the DS1/DSX-1 interface is configured for DS1 line buildouts, it can operate at lengths up to 6000 feet. POWER REQUIREMENTS The system power may be obtained from a DC power source if available, or an optional AC adapter available from ADTRAN.
61280.003L1-1B PAGE 19 INSTALLATION The supplementary equipment grounding conductor shall not be smaller in size than the undergrounded branch-circuit supply conductors. The supplementary equipment grounding conductor shall be connected to the product at the terminal provided, and shall be connected to ground in a manner that will retain the ground connection when the product is unplugged from the receptacle.
PAGE 20 61280.003L1-1B SECTION 2 interface circuitry is broken. The monitor jacks provide access to monitor the transmitted and received signals without interference. When connecting either T1 interface to the public switched network, an ADTRAN-provided crossover cable (part number 3125.M011@A) is required to meet FCC part 68 and IC CS03 requirements. This cable is required to cross-over the Tx and Rx pairs to meet the connecting arrangement of a network interface device.
61280.003L1-1B PAGE 21 INSTALLATION LINK PLANNING IMPORTANT The appropriate transmitter power must be calculated as part of the link planning. The factors that must be taken into account when planning a link are optimal received signal level, transmitter power, antenna feedline loss (each end), antenna gain (each end), free space path loss, and required fade margin. IMPORTANT The optimal signal level for the receiver is -60 dBm.
PAGE 22 61280.003L1-1B SECTION 2 ANTENNA GAIN Best performance will result from the use of a parabolic dish antenna. Antenna gain is determined by the size of the dish, with typical figures detailed below. Dish manufacturers will be able to supply gains for other types of antenna. Dish Diameter Gain (in feet) (in dBi) 2 ...................... 21 4 ...................... 27 6 ...................... 31 8 ...................... 33 10 ..................... 35 12 .....................
61280.003L1-1B PAGE 23 INSTALLATION PATH AVAILABILITY The availability of a path can be expressed by: availability = (1 - C x T x 2.5 x 10-6 x f x D3 x 10-F/10) x 100% where C is the climate factor T is the terrain factor f is the frequency in GHz D is the path length in miles F is the fade margin in dB Climate factors are given below. Climate Climate Factor Very Dry .............. 1/8 Temperate ............ 1/4 Humid .................
PAGE 24 61280.003L1-1B SECTION 2 SETTING THE TRANSMITTER POWER The FCC specifies the maximum transmitter power that may be used for antennae of a given gain. FCC rules Part 15, Subpart 247 allow for a maximum power of 1 watt into antennae of a gain less than or equal to 6 dBi. For every 3 dB of gain over 6 dBi, the transmitter must be reduced by 1 dB. The following table lists the maximum transmitter power for given antennae gains. Antenna Gain 6 dBi ......... 12 dBi ....... 18 dBi ....... 24 dBi .......
61280.003L1-1B PAGE 25 INSTALLATION To reconfigure the RFC interconnect, do the following: 1. Remove the four screws which retain the RFC cover and remove the cover. 2421 Anten na PLAN A 2462 2. The RF unit may be identified by following the connection from the port labelled “IF” on the rear of the RFC. This connection terminates at the RF unit. The diplexer may be identified by following the connection from the “Antenna” port on the rear of the RFC.
PAGE 26 61280.003L1-1B SECTION 2 9. Re-attach the cable assemblies from the ports labelled “Tx” and “Rx” on the RFC, and the ports labelled “2422” and “2462” on the diplexer. Cable connections should be aligned to each other as follows. Plan A Tx = 2422 Rx = 2462 Plan B Tx = 2462 Rx = 2422 10. Replace and secure the RFC cover. CONNECTING THE BBP AND THE RFC The BBP and the RFC are connected by an IF cable, either supplied by ADTRAN (for rack-mount assembly) or by the customer (for mast-mount assembly).
61280.003L1-1B PAGE 27 INSTALLATION SETTING THE BBP FREQUENCY PLAN Upon the initial application of power, the BBP will default to the factory-preset Frequency Plan, or to the Frequency Plan in use when the unit was last powered-down. The BBP attached to the RFC configured for Plan B must be set to Plan B by pressing the “Plan” switch on the front panel. The LED will indicate which frequency plan is active.
PAGE 28 61280.003L1-1B SECTION 2 3. If the systems are from different manufacturers, set the transmit frequencies as close as possible with different spreading codes. Other manufacturers may not use the exact frequency plans as the Tracer system, but keeping the frequencies close will reduce the probability of the transmitter(s) interfering with the colocated receiver(s). This equipment is authorized under CFR 47 Part 15.247.
61280.003L1-1B PAGE 29 INSTALLATION than the other. Changing the spreading code at each end may also allow interference to be mitigated. REMOTE BERT The Tracer includes a Bit Error Rate Tester (BERT) to verify that the installed system is operating correctly. When the “Remote Test” button is pushed on the local BBP, the remote end will send a BERT pattern for approximately ten seconds. The “Remote TST” indicator will turn yellow and remain on for the duration of the test.
