Micro Seven LS100

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.
