The configuration and labelling of the adapter wires
The POTS telephony boards audio output may be used for monitoring purposes
on the portable OPERA™ systems. To accomplish this, connect the POTS
telephony board audio output to the on-board audio input of the portable
machine, and the on-board line out signal to the speaker input, which is located
next to the power supply fans on the left side of the machine. All connections
here are using 3.5mm jacks and should be preconfigured. Again, be careful not
to mix up the on-board sound and the audio output of the POTS telephony
board with the optional high quality sound board. Next, the volume should be
adjusted. This needs to occur in two locations. First, the hardware control on
the right side of the portable OPERA™ system, and second, by using the mixer
control of windows. If the set-up is correct, double-click on the "Monitor Line
X" icon on the desktop, after pressing start in OptiCall, what is happening on
the telephone line X can then be heard.
Although the signalling on analog telephone networks differs significantly from
country to country and between individual PBXs, OPERA will usually
successfully establish test calls under most circumstances. Nevertheless it is
possible to adapt OPERA systems exactly to most networks. Preinstalled on all
OPERA systems is a variety of country/PBX specific settings. To change the
settings, open an Explorer window and go to:
