PLANET IPX-1500 - Manual (Page 52)

manually
Adjust Tone Table parameters manually
If you are sure that the busy tone frequency has been properly set, but the IPX-1500 still cannot release
the line port in three seconds, try to adjust the busy tone sensitivity. The default value is “Median”, the
“High” sensitivity will decrease the qualify condition of busy tone and make it more easy to detect busy
tone. And the “Low” sensitivity will make it more difficult to recognize busy tone. Sometimes, human
speech may cause DSP false recognize as busy tone. If so, lower sensitivity will reduce such problem.
But in any case, if the line port of IPX-1500 was locked, please use “disconnect” in CO & EXT selection
to release the line locked

CO & Ext Setup
This menu lists all CO lines and extensions. However, it does not mean that all these lines have
physical connections. For an unconnected or unused CO line, you should enter its setup menu and set
its operation mode to “Disabled”. This way the system knows which CO line(s) should never be
accessed. To set up a CO line or an extension, clicking on its icon.
