MINI-PBX
SIMULATOR model LS200-2D, provides a 2-line simulated telephone-line simulator
for testing telephone products under various telephone company characteristics
by programming loop current, loop voltage, ring signal frequency, ring signal
amplitude, and insertion losses between lines in a 19-inch rack-mount
configuration. LS200-2D contains RS232 interface and/or Ethernet Interface with
provided control software. LS200-2D contains true line impairment features for
providing envelope delay distortion, frequency attenuation, and signal
attenuation in typical long-distance telecommunication line. Amount of envelope
delay distortion and amount of random noise insertion is also programmable.
A
similar picture of model LS200-8A is shown above.

Disconnect Signal:
There
is interruption of loop current for 0.5 sec, which is programmable by control
software, when the other line terminates a call. For example: assuming that the
line 1 and 2 are connected. The loop current of line 1 is interrupted for 0.5
sec when the line 2 hangs up.
