MINI-PBX SIMULATOR, model LS100-4X is shown in the above picture.
MINI-PBX SIMULATOR, model LS200-8X, 8-line is shown in the above picture.
The Micro Seven Models LS100-4X and LS200-8X Mini-PBX Simulators provide multiple independent simulated telephone lines. Features include programmable telephone numbers, call progress tones, pseudo-line impairment mode with random noise, simulated PBX mode, stutter dial tone, programmable disconnect signal, programmable network response delay, and distinctive ringing features (for LS200-8X, not for LS100-4X). They are still specially designed to let engineers and technicians test modems and fax machines without obtaining extra in-house telephone lines. The LS100 is a small portable unit, and provide four telephone lines. The LS200 is a rack-mount unit, and provides eight lines.
The difference between models LS100-4A and LS100-4X or between models LS200-8A and LS200-8X is that models LS200-8A and LS200-8X contain alarm receivers for each line. Maximum four alarm panels for LS100-4X or maximum eight alarm panels for LS200-8X are installed. Each alarm panel may be installed for any lines in LS100-4X and LS200-8X. When alarm panel is triggered with events, telephone interface in an alarm panel goes off-hook, detects loop current, detects dial tone and dials a programmed telephone number. If the dialed number matches with required telephone number, LS100-4X or LS200-8X generates certain audio signals that are needed for the alarm panel. Then the alarm panel transmits alarm messages to LS100-4X or LS200-8X, which in turns transmits kiss-off tones for indicating receipt of the message. LS100-4X or LS200-8X then transmits received alarm message in ASCII formats to PC/server for processing. For Contact-ID alarm messages, alarm receiver software is included for LS100-4X and LS200-8X. The alarm receiver software displays all alarm messages received from lines of LS100-4X and LS200-8X. Alarm message format may be Contact-ID or pulse format 4+2.
Each line may be assigned a single-digit telephone number, corresponding to its line number, or programmable telephone number. Both rotary pulse and DTMF (tone) dialing are accepted for dialing. Features include dial tone, ring-back tone, and busy tone at the calling station. The ring signal is generated at the called line. A line connection is established between two stations when a call is answered. Pseudo line impairment circuit is selected when dialing unique numbers by providing additional 20 dB insertion losses for both signal directions and generating random noise. A transmit-power adjust potentiometer is provided for each line to lower signal output for testing telecommunication equipment at much lower signal levels. Indicators are included for POWER ON (front panel LED), and OH/BUSY for all lines (rear panel of LS100, front panel of LS200).
The models LS100 and LS200 provides many programmable features including telephone number method, telephone numbers, random noise amplitude, call progress tones (LS100 and some LS200 models), network response delay, disconnect signals, PBX mode, and stutter dial tone.
Telephone numbers for connecting alarm messages: The first digit requires “*”.
Handshake signal, dial tone/ring-back tone, and kiss-off tone generation:
Bypassing ring-back tone generation and generation of handshake signal is switch selectable feature. Generation of handshake signal for pulse format 4+2 optional. Generation of handshake signal for Contact-ID format is always enabled. More detail feature of alarm receiver, please check specification of Contact-ID and 4+2 alarm receiver, model LS15E+/4+2.
Telephone numbers for MINI-PBX:
1. Primary telephone number: A single-digit telephone number, which is equal to a line number
of a called line. selected by dialing 043 or line1 or 2 as a factory default.
2. Secondary telephone number: selected by dialing 044.
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
Note: simultaneous dialing from multiple lines is prohibited by suppressing generation of dial tones to more than one line because there is one DTMF receiver circuit in a box. Multi-line DTMF dialer option for LS200 eliminates the inconvenience of dialing restriction, and enables all lines to dial in DTMF and/or rotary-pulse method simultaneously.
Programming secondary telephone number: 022 (telephone number)
The factory default condition is 123456789+(line number).
Telephone number digit: 0 # 096 * n n n *, where nnn forms a 3-digit decimal number.
The default value is 10 digit. The maximum number is 18.
Simulated PBX Mode:
By dialing "9", dial tone returns when the Simulated PBX Mode was selected. Dialing "0#097*004*" for Simulated PBX Mode with dual frequency call progress tone or 0#097*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#097*000* with dual frequency call progress tone or dial 0#097*008* with secondary call progress tone.
Input impedance at 1 k Hz: 600 ohms +/- 5%
Signal Bandwidth:150 HZ to 5 k HZ without high-frequency option, 150 HZ to 150 k HZ with high-frequency option
Transmit Power Adjustment: A potentiometer for each line, accessible through a rear panel (LS100) or front panel (LS200) hole, provides a control range of 0 to -40 dB(maximum at full clockwise).
Pseudo-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. Note: Generic Line Impairment Options are also available for frequency attenuation characteristics and envelope delay distortion.
Random noise amplitude programming: 0#091*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=017.
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-pseudo-Line 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) and loop current: -20 volts and 25 mA
60 +/- 2% Hz sine wave. Normally 2 sec on 4 sec off with exception of distinctive ringing features programmed. 20Hz ring signal option (adjustable ring signal option) is available to adjust frequency and amplitude of ring signal. 30Hz ring signal (square wave) is available in LS100-4X.
Distinctive ring signal features only for LS200-8X (not for LS100-4X):
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
Signal power: nominal -20 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%.
Caution: When dual-frequency call progress tones are selected, new dial tone will not be
generated until a called line is answered or a calling line aborts a call.
Caution: The dual-frequency call progress tones are not available as a standard feature in LS200 with Multi-Line DTMF Dialer Option, but they are available as an All-line Dual
Frequency Call Progress Tone Option.
Call Progress Tones
Frequency: 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 . Dialing 07
switches back to the dual frequency call progress tones.
Note: The secondary call progress tone is a factory-default condition.
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 rear panel
Network response delay:
Time delay between the end of dialing and ring-signal application is programmable by dialing: 0#095*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, must be non-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#094*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.
