Description
The resistance of electrical current to alternating
current, measured in OHMs. Impedance occurs when
power or signal is transferred from one circuit to
another. The setting options are:
•
600 OHMs (domestic setting)
•
900 OHMs (international setting, depending on
the country)
•
Complex (for handling multi-component AC
circuits used by CO)
Can be single or double.
Select as None, FSK or DTMF for when receiving
caller ID digits.
Specifies the Flash Duration time in milliseconds,
with a range from 150 ms to 1000 ms.
When enabled, the system automatically takes the
trunk out of service whenever the trunk is seized.
Detects outgoing dial tone.
Enables a time-out period of 2 seconds (for ignoring
false CO disconnect signal), after answering an
incoming call.
Disconnects signal if CO breaks loop current. You
can set the duration from 200 to 1000 ms.
Busy tone (reorder tone, fast busy tone, error tone,
etc.) or dial tone (continuous tone, etc.). This should
be used in conjunction with drop in loop current. For
COs who cannot guarantee loop break, this may be
the only option.
