  • Page 3: Connection Possibilities

    FT635 Telephone Line Interface The FT635 telephone line interface (UELE) consists of a CPU card of Europe with an attached TIM (telephone interface module). There are 3 different housings available. The standard version is a flange aluminum housing. There also is a 19“ plug-in unit and a special version in the FT635 system housing.The version in the system housing has a connector which is pin-compatible to FT633UELE to the two-way radio.In the standard version only the most important connectors are available as sockets on the front.

  • Page 4: Connection Examples

    Connection examples There are different applications for the operation of a FT635 UELE: - automatic call forwarding from the telephone network to the radio - automatic call forwarding from the radio to a telephone Automatic call forwarding from the radio to the telephone two-way radio network resp.

  • Page 5: Carrier Detection

    Carrier detection The FT635UELE offers different possibilities of carrier detection. The carrier input can be low or high active and a pull-up resistance can be activated additionally. Alternative possibilities are the AF controlled carrier and the phantom control. For phantom control the solder jumper JP2 has to be resoldered.

  • Page 6: Transmitter Follow-Up Time

    Transmitter lead-up time The lead-up time is defined as the time between the activation of the transmitter and the start of the signaling (e.g. tone sequence). It can be adjusted from 0 to 990ms. Ex factory it is set at 100ms. Reg.

  • Page 7: In- And Outputs

    In- and outputs The FT635UELE has 16 in- and outputs and the carrier input, which can be used for special functions. The 16 in- and outputs can be programmed as either input or output. Ex factory I/O0-7 are configurated as open collector outputs and I/O8-15 as inputs with 27kOhm pullup to 5V.

  • Page 8: Outputs

    Outputs If the I/Os are configured as output, then there currently there are 3 possible functions: - additional PTT output - output for telephone active - digital output by tone sequence (see section Digital output control) Up to 4 I/Os can be programmed with digital output functions. Reg.

  • Page 9: Af-Signals (Telephone To Radio)

    AF-signaling pathways All AF pathways are switched wear-free with analog switches. The radio in-and outputs (except discriminator input and CTCSS output) are galvanically decoupled using a transformer. AF-signals (telephone to radio) The level of the incoming telephone signal is adjusted in register 620. The AF signal is transferred from here to the the radio output by means of the output level adjustment.

  • Page 10: Tone Sequence Encoder And Decoder

    Calling the mobile ID via telephone is started with the end key or automatically after the complete input of the mobile ID. Ex factory telephone dialing uses DTMF, but pulse dialing is also possible. Specifications for the DTMF encoder and decoder can be adjusted in the TIM, if problems arise.
  • Page 11 Incoming tone sequences are checked for conformity with the decoders T1-T10. If there is a match, this decoder is processed and all the following decoders with lower priority are not checked anymore. The correct number of tones and conformity with the key tones is necessary for decoding.

    to be received not later than after 15 seconds and each further tone not later than after 5 seconds. All DTMF-tones received from the radio user are buffered so that fast incoming DTMF-tones can be processed. After entering the telephone number completely the dialing process is started by pressing the END key (normally the #-key).

    be completely comprised in the tone sequence or it is composed of variable digits in the tone sequence and fixed digits in the register. After the tone sequence has been identified correctly the line is seized and according to the configuration it will be checked if there is a call tone (see section Call tone detection).

    Reg. Function 367 1.- 3. digit: maximum receiving time for Simplex nnn * 1s Modulation monitoring The connection is disconnected after N seconds without speech modulation and the line is free. The maximum duration of a call without speech modulation is adjustable from 1 to 99s or can be turned off with 0.

  • Page 18: Voice Announcement (Option)

    There are two different ways of compressing speech. The A-Law compression halves the resolution from 16 Bit to 8 Bit and half the Baud rate reduces the sampling rate from 28,8kHz to 14,4kHz. For especially long delays both compression methods can be combined. Ex factory the operation mode "Simplex (Vox)"...

  • Page 19: Example For The Configuration

    Example for the configuration 1. 5-Tone sequence system with mixed vehicle- and telephone numbers and dialing from the speed dial memory - mobile call ID 12100-12149, two digit input - telephone numbers 12150-12199, speed dialing register 050-099 - register 320 = 121FFFFF: decodes all tone sequences which begin with 121 - register 330 = 52045000: 1.

  • Page 20: Call Progress Tone Detection

    programmed vice versa, then the starting call 12199 would be decoded as direct dialing tone sequence and would be discarded, because it does not fulfill the condition for the 1. dialing number. A further comparison with the lower decoders 2-10 will not take place after that.
  • Page 21 Reg. Function 368 1.- 3. digit: maximum duration of dial tone nnn * 1s Configuration table for call progress tones There is a configuration table for call progress tone detection in the EEPROM. In this table you can define which tone/pause ratio will be detected as dial tone or busy tone. Ex factory this table has already been programmed with two possible dial tones and with four possible busy tones.

An additional receiver is necessary for Duplex or Semi-Duplex operation, which monitors the transmitting channel. Carrier detection on the transmitting channel has to be read via an input. The normal carrier input can be used for Simplex operation.
