Micro Seven, Inc.®, 2004
Micro
Seven, Inc. model LS15-E contains both Alarm-Receiver Simulator and PBX
simulator/telephone-line simulator functions. Micro Seven, Inc. model LS15-E+
contains Alarm-Receiver Simulator for simulated CO line and modem port to
accept alarm messages either directly from alarm panels or via PBX/telephone
port. The Alarm-Receiver Simulator function provides simulated telephone-line
and alarm receiver for testing and demonstrating alarm panels for the Ademco®
(registered trade mark by ADEMCO Group, a division of Pittway) Contact ID
Protocol. The simulated telephone-line functions include generation of
dual-frequency-type dial and ring-back tones, detection of DTMF and
rotary-pulse dialing pulses, and battery-feed function. The LS15-E and LS15-E+
provide functions of generation of handshake tones and kiss-off tones,
receiving alarm messages, check-sum calculation, and transmitting alarm
messages in ASCII format at RS232C interface to a PC. Telephone numbers and
signal attenuation are programmable by control software that is provided with
LS15-E, and the programmed parameters are stored in non-volatile memory inside
LS15-E. It operates with an AC adapter that is provided with LS15-E.
The features of the model LS15-E+ is
slightly different from model LS15-E. The model LS15-E+ accepts alarm messages
from simulated CO line at line 1 or from modem port at line 2. Alarm panels may
directly be connected to line 1 of LS15-E+ with a telephone cable. Connection
is made to PBX inside line at line 2 of LS15-E+. Alarm panel messages are sent
via PBX line to line 2 of LS15-E+. Handshake signals, kiss-off tone, ASCII data
output, and Ademco protocol is identical to simulated CO line at line 1. In
addition to unique modem port at line 2, LS15-E+ is also equipped with an Audio
Monitor with a built-in speaker and external audio jack to monitor handshake
signals, kiss-off tones, and DTMF tones.
Model LS15-E contains PBX
simulator/telephone-line simulator function, which simulates two dial-up
telephone lines for testing and demonstrating telecommunication equipment, is
available from line 2 calling line 1. When a correct telephone number is dialed
at line 2, ring signal is produced at line 1. When the call is answered at line
1, bi-directional signal paths are established between two lines. The
telephone-line simulator features are very similar to ones in LS15-C. Many
features include 20HZ sine-wave ring signal, dual frequency and single
frequency call progress tones, switching extra 20 dB signal attenuation on/off,
primary and secondary telephone numbers, stutter dial tone, PBX mode, hot-line
mode, distinctive ring, network delay, and disconnect signal.

Introduction
of alarm-receiver function
Traditionally,
when alarm panels are tested in the manufacturing or demonstrated in the sales
offices, alarm receiver with two public telephone lines are required in
addition to a computer. The Micro Seven model LS15-E eliminates an alarm
receiver and two telephone lines by combining both of telephone line simulator
and alarm receiver functions for the application. Here, an alarm panel is
connected to the line 1 of LS15-E. The RS232C port of a PC is connected to the
rear panel connector of LS15-E with special cable and connector that are
provided with LS15-E. Micro Seven’s LS15-E control software provides a tool to
display incoming alarm messages. First, the alarm panel goes off-hook at line
1. The loop current is flowing at the line 1. Then, the alarm panel dials
either primary telephone number "2" (single digit) or secondary
telephone-number that is assigned for line 2(programmable one) depending on which
telephone number scheme is selected. When the dialed number is correct, the
LS15-E provides ring-back tone for two seconds. Then, there is no sound for
four seconds. And ring-back tone is generated for two seconds. After 0.6
seconds, the LS15-E transmits handshake tones of 1400 and 2300Hz for 100 ms
each separated with 100 ms silence period. When the alarm panel receives the
handshake tones, the alarm panel transmits a string of alarm message in DTMF
tones with a check-sum at the end. When the alarm message with correct
check-sum is received by LS15-E, it transmits the kiss-off tone to the alarm
panel. LS15-E also transmits the ASCII equivalent of the alarm message at the
RS232C interface to the PC. Then, the alarm panel either transmits a new alarm
message after a short delay or hangs up with the telephone line to terminate
the call. If the alarm panel did not receive the kiss-off tone, the alarm panel
may repeat transmitting the same alarm message four times. When LS15-E sees the
on-hook-state, it turns off the loop current for a few hundred milliseconds as
a disconnect signal. Then, LS15-E is now ready for a new call from the alarm
panel. LS15-E is compatible with the Ademco ® Contact ID Protocol for
Alarm System Communications. LS15-E may be programmed to accept alarm messages
both from alarm panels at line 1 and line 2. LS15-E+ accepts alarm messages
from alarm panel at line 1 or via PBX line at line 2.

Introduction
of PBX simulator/telephone-line simulator function for LS15-E
The PBX
simulator/telephone-line simulator function is for testing and demonstrating of
telecommunication equipment in engineering, manufacturing, and fields. It
contains dual frequency call progress tones, 20Hz sine wave ring signal, short
or programmable telephone number, stutter dial tone, and distinctive ring
signals. It also contains a line-impairment mode with extra insertion losses.
The LS15-E may also be operated by an external DC source with Car Battery
Adapter or the AC/DC adapter, which is provided with the instrument. Car
Battery Adapter and 220V version of AC/DC adapter are available as options. The
LS15-E is also equipped with a forced-disconnect feature where disconnect
signals are sent to calling and called lines. Programmable network response
delay simulates time delay after completion of dialing. Simulated PBX mode
returns dial tone after dialing 9. The secondary call progress tone generates a
single-frequency tone instead of dual-frequency call progress tone. The
programmable disconnect signal changes duration of the disconnect-signal.
