7-8 AltiWare OE System Installation & Administration Manual
Description
Select from:
•
Enable Dial Tone Detection (Outgoing)—
detection of outgoing dial tone.
•
Enable Polarity Detection (Incoming)—detection
of incoming polarity. Polarity detection is used
when the CO or the connected PBX provides
polarity reversal on the tip and ring.
Select from:
•
Tone—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.
•
Polarity Reversal—a reversed battery signal. You
can set the Loop Break Signal to either 200 or 600
ms.
Slide setting adjusts the incoming volume from
-6 dB to 6 dB for every Quantum Trunk channel.
The default setting is 0 dB, and it is highly recommended
not to change this setting.
Caution: Setting the volume too high will cause
distortion in voice quality and/or missed
DTMF digits.
