Class500-SMS is designed to simulate all kind of telephone network included SMS SMSC, CID type I, type II, Line feeding, tone generation, tone detection, ringing signal and charge metering pulse etc.. As it uses digital signal processing, the output signals are adjustable with high precision and over wide ranges.

Class 600-SMS
A SMS SMSC Simulator And SMTE Emulator

For the first time combined SMS network simulator, SMS terminal emulator and an universal PSTN Line simulation all in one, Class600-SMS is an enhanced version of Class500-SMS, it offers a full single port features of Class500-SMS with extra SMS SMTE simulation mode. As a terminal simulator, the Class600-SMS in quiescient state is ready to receive Caller ID and SMS. It can establish a loop state, dialing with independent DC resistance and AC impedence.

Globecall Caller ID tester has built in 60 sets of single-test and 3 sets of multi-test programme. It supports multi-country standards. With stable quality, portable size, easy to operate and competitive price, Globecall is the best choice for development and production caller ID products.

Globecall 2000 is an extremely flexible protocol generator. It is intended to assist greatly in the design of telecommunication products for use with the caller display service.

The tester has 14 built in test sequences, which can be set to cover a variety of specification requirements. The user can vary parameters by use of a PC in Terminal mode, or by using the optional orster hand held terminal. The factory defaults can be changed by the user, to customize the tester for particular applications. Globecall 2000 offers multi-country testing with the one version of tester, there is no need to buy different options for different countries both fsk and DTMF caller ID is catered for on-hook and off-hook (call waiting) signal can be generated.

MASC SMS is designed for connecting in parallel to Public Switched Telephone Network to captures the traffic, decodes and displays FSK or DTMF Caller ID information and SMS information on PC for both on-hook and off-hook data transmission.
MASC SMS can be left on site or transferred from site to site for both real-time reporting and local data-capture.

Euro-SIM is an exchange simulator with full facilities to test and demonstrate a wide range of telecommunication apparatus in many different countries. Euro-SIM has many possible applications: simple telephones, answering machines, payphones, modems, fax machines, messaging systems, callloggers, autodiallers, PC diallers etc..

The GS100 universal ringing generator is capable of generating most call signals that are present on telephone networks all over the world.
The signal can be polarise or non-polarised. It is adjustable for frequency and amplitude, and the sequence repetition rate has four individually adjustable elementary time values.

Fully micro-computer controlled. Driver compatible with National Instruments LabWindows CVI environment is available

With exceptional simplicity and precision it is used to characterize in real time any signal between 10 Hz and 20 kHz in amplitude, frequency and duration and with time/date stamping.
Its high performance is based on powerful signal processor (DSP) with algorithms optimized for telephony. Computer controlled.

Double FFT from 10Hz to 20kHz translated into 10 more representative lines. Precision 1 Hz.
Input dynamic range : 90dB - 16 bits.
Range X1 : from -60 dBm to +19 dBm
Range X10 : -40 dBm to +39 dBm
Spectrum display : lower limit from -60 dBm to -20 dBm, dynamic range : 40 or 60 dB.
Recorder display : time/date stamping of events. Memory size of 200 events.
time/date stamping resolution : 5 ms. Floating zero point.
Specific numerical filters : V23 UART (Caller ID), Tones, DTMF (Q23), 4.8 kHz carrier, taxation 12 ou 16 Khz.

The ATS 1000 is intended for use in compliance or pre-compliance laboratories for checking analogue terminals against the relevant approval requirements. Although, designed specifically for tests against CTR-21, this does not preclude it from use for tests against other specifications.
