Introduction:
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.
SPECIFICATIONS (advance
information-subject to change):
Dialing:
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
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 LS100-4X.
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:
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.
