   1. General

         This document defines the requirements from the Modular Programmable
         RF unit (MPRF). The MPRF shall include the RF to Base band receiver of
         the base station for the TELETRAC system. The MPRF is the second
         ggneration, multichannel version, of the RSDU that was integrated in the
         first gerieration base station.
         The MPRF receives BPSK signals from VLU units and FSK signal from
         Paging transmitters and outputs corresponding base—band signals to the
         digital processor (CCSP). The MPRF shall support two types of BPSK
         signals, wide band for location signals and narrow band for massaging.
         The MPRF shall support paging channels of POCSAG or ReFLEX types.

         including shielding and connectors.

         The MPRF shall include two Band—A (BSK) antenna inputs (to support
         diversity reception) and one Band—B (FSK) antenna input.
         An external duplexer similar to the one in use in RSDU (adapted to the
         shifted FSK band) will be incorporated in one of the PSK inputs and the
         FSK antenna input and the second PSK antenna shall be connected to PSK
         band—pass filter only.
         The reference clock for the overall Base Station operation will be an OCXO
         with digital frequency control. All other frequencies required by the base

                — Dual Narrow band PSK receiver.
                — FSK receiver

         The MPRF will be controlled by the CCSP. The MPRF shall contain a
         controller that will control and monitor the MPRF receivers and will be
         controlied by the CCSP. The CCSP will program the center frequency of
         each BPSK and FSK receiver. The controller will also perform diagnostics
         of the MPRF unit (controlled by CCSP).

       protocol:
        * The CCSP operates as master and the MPRF operates as slave
        * The MPRF cannot initiate a transission to the CCSP unless the CCSP sent a
          command (e.g. status request, set parameters, ..etc.) to the MPRF.
        * The MPRF should response within TBD msec.
        * The MPRF messages are divided into three categories :
          0 ACK Message
          0 NAK Message
          0 Message with data

        NOTE: The MPRF has been tested and found to comply with the limits for a Class B
        digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
        reasonable protection against harmful interference in a residential installation. This
        equipment generates, uses and can radiate radio frequency energy and, if not installed
        and used in accordance with the instructions, may cause harmful interference to radio
        communications. However, there is no guarantee that interference will not occur in a
        particular installation. If this equipment does cause harmful interference to radio or
        television reception, which can be determined by turning the equipment off and on, the
        user is encouraged to try to correct the interference by one or more of the following
        measures:
        «Reorient or relocate the receiving antenna.
        —Increase the separation between the equipment and receiver.
        —Connect the equipment into an outlet on a circuit different from that to which the receiver
         is connected.
        —Consult the dealer or an experienced radio/TV technician for help.


        Changes or modifications to this unit not expressly approved bythe Tadiran Telematics Ltd.
        could void the user‘s authority to operate the equipment.

   1. General

         This document defines the requirements from the Modular Programmable
         RF unit (MPRF). The MPRF shall include the RF to Base band receiver of
         the base station for the TELETRAC system. The MPRF is the second
         generation, multichannel version, of the RSDU that was integrated in the
         first generation base station.
         The MPRF receives BPSK signals from VLU units and FSK signal from
         Paging transmitters and outputs corresponding base—band signals to the
         digital processor (CCSP). The MPRF shall support two types of BPSK
         signals, wide band for location signals and narrow band for massaging.
         The MPRF shall support paging channels of POCSAG or ReFLEX types.

        The MPRF will be controlled by the CCSP. The MPRF shall contain a
        controller that will control and monitor the MPRF receivers and will be
        controlled by the CCSP. The CCSP will program the center frequency of

   2.1.3 FSK Receiver.

         The MPRF shall include up to two FSK receiver modules. This module will
         include single FSK receivers. This module shall be able to receive 25 KHz
         FM signals band at the 927.75—928 MHz band. The output of each receiver
         will be a FM—decoded signals (the discriminator output signal).
