The Incoming Ring Type can be single or double.
The Detect Trunk Status By Loop Current checkbox, if selected, causes
detection of the Quantum trunk status using a loop current.
Enable Caller ID Receive needs to be selected to receive caller ID digits.
Centrex Flash Duration (ms) specifies the Flash Duration time in
milliseconds, with a range from 50 ms to 1000 ms. This setting
complements the Centrex Flash Support option in the General window for
the trunk.
Trunk Seizure and Disconnection
Trunk Seizure Confirmation is one of two options:
• 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.
Similarly, Disconnect Supervision is also one of two types:
• 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.
Receiver Gain and Transmission Attenuation
The Receiver Gain and Transmission Attenuation slide settings adjust
the incoming and outgoing volume, respectively, for every Quantum trunk
or extension.
The default settings for each of these is 0 dB. Caution should be used in
changing the Receiver Gain or Transmission Attenuation, because, too
high a setting causes distortion in the voice quality.
Incoming and outgoing volume for Quantum trunks or extensions can also
be configured through the Quantum Board Channel Configuration
option in the Management Menu. See page 83.
