Type Acceptance Information for TS4000 Radio Modem with 3422 TransceiverProposed FCC ID JWFTS4000CTeledesign Systems, Inc Confidential Information Page 1PURPOSEThe purpose of this document is to provide information in support of type acceptance testing andreport generation in pursuit of a Grant of Equipment Authorization under FCC Parts 15 and 90 andIndustry Canada RSS-119, RSS-210 and ICES-003 for Teledesign’s TS4000 Radio Modem.INTRODUCTIONThe TS4000 is a high-speed radio modem that consists of a modem board, radio transceiverboard and metal enclosure. The radio transceiver board connects to the modem board with aflexible printed circuit.Radio Transceiver BoardThe radio transceiver board for this application is an E.F. Johnson DL3422. This device is beingused without any modifications. The DL3422 has received FCC type acceptance with an FCC IDof ATH2423422-007. All circuit descriptions and details for the radio transceiver can be found inthe type acceptance document for the DL3422. A copy of this has been included with thisapplication. The radio transceiver is available in a frequency range from 132-174 MHz andincludes a temperature stable reference oscillator with a frequency stability of ± 2.5 PPM.Modem BoardThe modem board provides the serial data interfaces that the user’s equipment interfaces to. Themodem board also controls the operation of the radio transceiver. This control includescontrolling the radio power and frequency and also controlling the modulation, data rate andfrequency deviation of the transmit signal. Note that it is this transmit signal that defines theemission bandwidth and spectral efficiency.Radio Flex CircuitA flex circuit is used to interconnect the radio transceiver board to the modem board. This flexcircuit is also used to interconnect the serial port 2 connector to the modem board. The J11interconnecting diagram included with the modem board schematic provides the specificconnections provided by the flex circuit for connecting the radio transceiver to the modem board.Configuration SoftwareIBM compatible configuration software is used to control all aspects of configuration, tune up andtest of the TS4000 radio modem.General InformationManufacturer: Teledesign Systems Inc.2635 North First Street, Suite 205San Jose, CA 95134408-232-0180Contact Person: Mark HubbardProduct Trade Name: TS4000 Radio ModemProduct Model Number: TS4000-05Cff where: ff - indicates frequency rangeProposed FCC ID: FCC ID: JWFTS4000CProduction Plans: Teledesign Systems Inc. plans to produce this product inquantity (greater than 1) production runs.Radio Transceiver Manufacturer: E.F.

The 4 level FSK modulation is provided to allow a high spectral efficiencyfor a given channel bandwidth. The GMSK modulations are provided in order to be compatiblewith other products and data communications standards.Channel Bandwidths:Our goal is to certify the TS4000 at four different channel bandwidths: 20K0, 16K0, 11K2 and6K00 (the use of the 6K00 bandwidth is limited to the subparts shown above). This is to allow theTS4000 to be setup for the most efficient operation for a given channel bandwidth that a user islicensed for.4 Level FSK 20K0F1D:Channel Baud Rate (B) = 32000 bpsModulation Frequency (M) = B (1/8) = 4000 HzPeak Deviation (D) = 6000 HzBandwidth Calculation = 2 (D) + 2 (M)Bandwidth Calculation = 2 (6000) + 2 (4000)Bandwidth Calculation = 12000 + 8000Bandwidth Calculation = 20000 or 20K016K0F1D:Channel Baud Rate (B) = 24000 bpsModulation Frequency (M) = B (1/8) = 3000 Hz
