Micro Seven Inc.® model LS15-1-ETS for developing caller-ID for European market

copyrights Micro Seven, Inc.®, 2010, 2011, 2012, 2013

 

The Caller-ID features of Micro Seven model LS15-1-ETS simulates caller-ID services with north American single and multiple data format messages (Bellcore mode) and ETS mode. A calling-line's 10 digit telephone number including an area code and name are transmitted along with date and time during the first silence period of the ringing cycle at a called line. Depending on a pre-programmed condition of a calling line, a privacy or out-of-area status code may be transmitted instead of a calling number and name. However, date and time information are always transmitted. The Caller-ID features provide testing and demonstration of various caller-ID displays or receivers without obtaining caller-ID services from public telephone companies.

 

The caller-ID information which consists of date, time, calling number (or privacy status or out-of-area status), name (optional), and call qualifier (long distance indication-optional) is transmitted only once during the silent period after the first ringing cycle. If the called line represents an off-hook condition (answers the call) during the first ringing cycle or the first silent period, the transmission of caller-ID information ends. A 10-digit telephone number, or privacy status or out-of-area status for each line, is programmable by dialing a special code. The date and time are programmable by dialing a special code also. To test caller-ID display devices continuously, LS15-1-ETS may be programmed to generate caller-ID data after every ringing period.

 

The single or multiple data message format may be selected by entering a special code. The multiple data message format provides name of caller in addition to date, time, directory number, and the long-distance call qualifier. LS15-1-ETS may also be programmed to transmit Visual Message Waiting Indicator messages without ring signal. The channel-seizure period and marking-period may also be programmed in LS15-1-ETS.

Dialing:

     Telephone numbers:

          1. Primary telephone number: selected by dialing 043 or line1 or 2 as a factory default.

          2. Secondary telephone number: selected by dialing 044.

              A secondary telephone number is same as a calling number in caller-ID.

             Warning: Using secondary telephone number in a privacy mode is prohibited.

              Please read section 4.3 Programming of Caller-ID Parameters for details.

     DTMF dialing signal power: -13dBm to +5dBm per a frequency with no more than 4dB

                                                 difference between frequencies.

     DTMF dialing detection time: 45 ms

     Pulse dialing: Break period: 45 to 75 ms (60 ms nominal)

                            Make period: 30 to 60 ms (40 ms nominal)

 

Simulated PBX Mode:

     By dialing "9", dial tone returns when the Simulated PBX Mode was selected.

     Dialing "0#252*004*" for Simulated PBX Mode with dual frequency call progress tone or

     0#252*012* for Simulated PBX Mode with secondary call progress tone.

     Note that the regular dialing methods work as well here. For example, if the secondary  

     dialing method with a telephone number of  3456789012and the PBX mode are enabled,

     dialing of 3456789012 or 93456789012 would ring the other line. To return to non-PBX

     mode, dial 0#252*000* with dual frequency call progress tone or dial 0#252*008* with

     secondary call progress tone.

 

Line Characteristics:

    Input impedance at 1 k Hz: 600 ohms +/- 5%

    Signal Bandwidth: 150 HZ to 3.5 k HZ

 

Line Impairment Mode:

    When a number of 00 and line-number is dialed, line impairment circuit with additional 20dB

    of insertion loss and -55dBm of random noise are added to signals between line 1 and 2.

    Random noise amplitude is also programmable. Frequency attenuation characteristics and

    envelope delay distortion of signals are not affected.

 

Random noise amplitude programming:

    0#168*nnn*

    The random noise amplitude is set at –55 dBm as a factory default value, but it may be

    changed by the above dialing method. The factory default value is obtained with nnn=011.

    The smaller number, the lower signal power.

     i.e. nnn=176 for –31 dBm, nnn=088 for -37 dBm, nnn=044 for -43 dBm,

     nnn=022 for -49 dBm, nnn=005 for -61 dBm , nnn=000 for -67 dBm of random noise.

 

Non-impairment mode:

    When a number of 09 and a line number is dialed, the insertion loss between

    lines becomes only 1 dB, and the random noise is removed. This is the factory default

    condition.

 

Battery-feed voltage (loop voltage):

    Selection between -20 or -40 volts:

    1. -20 volts mode is selected by dialing 041, and it is a factory default condition.

    2. -40 volts mode is selected by dialing 042. The battery-feed voltage is changed to -20 volt

        mode when called line is ringing or in its off-hook state (answered). When the called line

        hangs up the line, the battery-feed voltage is returned to -40 volts.

  

Ring Signal:

    20 +/- 2% Hz sine wave. Normally 2 sec on 4 sec off with exception of distinctive ringing

    features programmed.

   Amplitude: 67V RMS into open circuit. It is 66 V RMS into RN=0.1, 56 V RMS into RN=0.5,

        48V RMS into RN=1, and 40V RMS into RN=1.7.

        According to the FCC-part 68 rule, the RN=7000/(equivalent resistive value in ohms)

       for ring signal of 20Hz +/- 3%.

   The ring signal at a called line is disabled by dialing *0. To enable back to ringing at a called

   line, dial *0 again.

 

Distinctive ring signal features:

    The following distinctive ringing pattern is enabled instead of standard 2 sec on/ 4 sec off

    ringing pattern:

    (a). Dialing 0 * 1 + (line number): 2 sec on/ 4 sec off   (default condition)

    (b). Dialing 0 * 2 + (line number): 0.8 sec on, 0.4 sec off, 0.8 sec on, 4 sec off

    (c). Dialing 0 * 3 + (line number): 0.4 sec on, 0.2 sec off, 0.4 sec on, 0.2 sec off, 0.8 sec on,

          4 sec off

    (d). Dialing 0 * 4 + (line number): 0.3 sec on, 0.2 sec off, 1 sec on, 0.2 sec off, 0.3 sec on,

           4 sec off

 

Off-hook impedance requirement: 400 ohms maximum DC, 600 ohms nominal AC

 

Call Progress Tones:

    Standard dual-frequency call progress tones: nominal -16 dBm.

        Dial Tone: 350 Hz + 440 Hz, continuous unless programmed for stutter dial tone

        Ring-back Tone: 440 Hz + 480 Hz, 2 sec ON/4 sec OFF.

        Busy Tone: 480 Hz + 620 Hz, 0.5 sec ON/0.5 sec OFF.

        Accuracy in frequency component: +/- 1%.

 

    Secondary Call Progress Tones: (480 Hz +/- 1%)

        Dialing 07 enables the secondary call progress tones. Instead of generating dual

        frequency call progress tones, single-frequency tone of 480 Hz is produced with signal

        power of –18.5 dBm. Dialing 07 switches back to the dual frequency call progress tones.

 

Stutter dial tone:

    Dialing 046 enables stutter dial tone with three of 0.1 seconds on/off period following with

    continuous dial tone.

    Dialing 045 disables the stutter dial tone. It is a factory default condition.

 

Line Input Jacks: USOC-RJ11-C, standard modular phone jacks

 

Power Switch: on when the switch is pushed in, off when the switch is pushed out.

 

Hot Line Mode:

    Dialing 06 enables the Hot Line mode, which calls the other line without dialing a number. To

    return to non-hot-line mode, dial 06 during the first 0.5 seconds right after off-hook.

 

Network response delay:

    Time delay between the end of dialing and ring-signal application is programmable by the

    following dialing:

         0#170*nnn*, where nnn is a 3-digit decimal number between 1 and 255. The time delay is

         determined by 8.6 ms x (nnn-1). The number, nnn, should not be zero.

         The factory default is 0 seconds.

 

Forced called-party disconnect:

    When two lines are connected and one line hangs up, disconnect signal is generated to both

    lines.

 

Programmable disconnect signal:

    The disconnect signal, which is interruption of loop current at the end of call when one line

    hangs up is programmable by the following dialing:

         0#169*nnn*, where nnn is a 3-digit decimal number between 1 and 255. The time delay is

         determined by 8.6 ms x (nnn). The number, nnn, should not be zero.

    The factory default is 320 ms.

 

AC/DC Adapter: 117VAC +/- 5%, or 220VAC +/- 5%(for 220V unit)

 

AC/DC Adapter or Car Battery Adapter input (also as a battery charger): 12VDC

    unregulated, 800mA maximum 

 

Line Status Display: red LED for each line to indicate off-hook status (continuous on)

    or ringing status (blinking)

 

Calibration: not required

 

Power On Indicator: green LED display on front panel

On-hook and off-hook (call-waiting caller-ID) caller-ID FSK Generation:

    Single message and multiple message-format caller-ID FSK generations are supported.

    Programming parameters includes telephone number, name, date and time, telephone

    number length, name length, privacy/out-of-area, call qualifier on/off, visual message on/off,

    marking period before FSK data, silence period after the first ring, continuous caller-ID

    generation on/off, and wrong checksum generation on/off.  No ring signal is

    produced for the visual messages. It also includes an FSK data expansion capability of

    caller-ID data.
