Introduction:
Micro Seven Model LS25, the Cheapest Line
Simulator, CO simulator, or MINI-PBX SIMULATOR, provides complete telephone
line simulation including 30Hz square-wave ring signal, dual frequency call
progress tones, battery-feed, DTMF& rotary-pulse dialing, and programmable
telephone number in a smaller case than LS15 family products. Model LS25 is
powered by a standard equipped AC/DC adapter. An international power adapter option
for LS25 provides four different power plugs (US/Japan, BK, Australian, and
Continental European) for 90-250V power range. An optional car battery adapter
may be used to power model LS25. The application of model LS25 includes modem
and telephone sets testing in engineering, manufacturing, and fields. The LS25
contains dual frequency call progress tones, 30Hz square wave ring signal,
short primary or programmable secondary telephone number, caller-ID signal,
stutter dial tone, network response delay, disconnect signal, hot-line mode,
PBX mode, and secondary dial-tone. The LS25 also contains a
pseudo-line-impairment mode generating random noise. The programmable
parameters include telephone numbers, network response delay, caller-ID
parameters, call progress tones and disconnect signal period. All the
programmable parameters in non-volatile memory are restored when the power
switch is turned off. Please note that LS25 provides telephone line simulator
function for one direction only. Model LS15-C1, LS15-1 and LS15 provide
telephone line simulator functions for both calling directions.
SPECIFICATIONS
Dialing Telephone Numbers:
1. Primary telephone number as a factory
default.
2. Secondary telephone number (programmable up to more than eleven digits
long). Please note that a number can not start with 0.
Dialing Method:
DTMF 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.
Line Characteristics: Input impedance at
1 k Hz: 600 ohms +/- 5%
Signal Bandwidth: 150 HZ to 3.5 k HZ
Line Impairment Mode: Line impairment
circuit with additional 20dB of insertion loss
Battery-feed voltage (loop voltage): -20
volts
Ring Signal: 30 +/- 2% Hz square wave.
Normally 2 sec on 4 sec off.
Amplitude: 75VRMS minimum
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%)
Secondary call progress tones may be selected instead of generating dual
frequency call progress tones, single-frequency tone of 480 Hz is produced with
signal power of -18.5 dBm.
Stutter dial-tone: enable/disable
Line Input Jacks: line 1: call
originating line, line2: call receiving line, USOC-RJ11-C, standard modular
phone jacks
Power Switch
Hot Line Mode: In hot Line mode lifting a
handset at line 1 calls line 2 automaticallyline without dialing a number. Note
that the hot line mode is not restored in power up.
Pseudo line impairment condition mixing
random noise into 2-way voices is entered by dialing “002” at line 1
(originating line). Ideal telephone line condition without random noise is
obtained by dialing “092”.
Network response delay: Time delay
between the end of dialing and ring-signal application is programmable.
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.
All programming of telephone numbers,
call progress tones, random noise amplitude and other parameters are doe by
dialing unique codes starting “0”.
Power input: receiving 24VDC with 2.1mm
connector
AC/DC Adapter: provided as a standard
accessory for 117VAC +/- 5%, or optional for 230V or international power
adapter
Calibration: not required
Power On Indicator: green LED display on
front panel
Dimensions: 6.5 cm (2.5") W x 3.3 cm
(1.5") H x 18 cm (5") L
Weight: about 250g (about 0.5 lbs.)
Environmental: Operating temperature: 0
to 35 degree C, Humidity: 85% RH at 35 degree C
Warranty/Service: 6 months limited
warranty. No warranty if any factory seal is broken. Service is performed at
the factory, usually within 5 working days.
Options and Accessories:
Car Battery Adapter
International power adapter option (117V
input unit is a standard.)
