Introduction:
The Micro Seven Models LS100A and LS200A
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. 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.
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.
SPECIFICATIONS
Dialing:
Telephone numbers:
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
nominal)
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.
Line
Characteristics:
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
Ring
Signal:
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
LS100-4B.
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:
1.
Dual-frequency
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.
2. Secondary 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.
