  • Page 11: Section 1 Tracer Description

    ESCRIPTION ECTION NTRODUCTION 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 12: Applications

    Mast and Rack mount RFCs may be mixed to accommodate individual system requirements. 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.

  • Page 13: 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. ODING Many different pseudorandom sequences exist.

  • Page 14: Forward Error Correction

    Error correction can be accomplished by allowing the receiver to request the re- transmission of 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.

  • Page 15: Ds1/Dsx-1 Interface

    DS1/DSX-1 I NTERFACE When connecting the interface to the public switched network, an ADTRAN-provided cross-over 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.

    ECTION 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 I NTERFACE A serial interface port using RS-232C signal levels is provided for attaching a VT-100-compatible terminal.

  • Page 19: 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.

    Figure 1-10. Mast-Mount RFC Housing TRACER Figure 1-11. Rack-Mount RFC Housing NTENNA Tracer is intended to be coupled with an antenna that is directional and provides signal gain.

    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 28: Installation

    The system power may be obtained from a DC power source if available, or an optional AC adapter available from ADTRAN. The Tracer can operate from a power supply between 21 and 56 volts DC, with either polarity referenced to ground, and consumes 30 watts of power.

  • Page 30 The LBO setting allows each DS1/DSX-1 interface transmitter to drive the interface with the correct signal strength based on the line attenuation between Tracer and the attached equipment. The LBO is independently set for each interface via rotary switches on the front panel.
  • Page 31 61280.003L1-1B NSTALLATION LANNING I M P O R T A N T 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.
  • Page 32 61280.003L1-1B ECTION NTENNA Best performance will result from the use of a parabolic dish antenna.

  • Page 37 PREADING The spreading code for each end must be the same. The choice of operating code is selectable by the operator or the installer. Tracer is shipped in a matched (default) configuration. W A R N I N G It is possible for the spreading code to be changed remotely through the VT-100 interface from the other end of the link.
  • Page 38 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 co- located receiver(s).
