Triton Analog Trunk GS/LS Properties
MaxCS 7.5 Administration Manual 151
Match Result button
Shows the result obtained the last time the Match Impedance button
was clicked for that trunk.
Disable Impedance Match
During System Startup Check to disable automatic impedance matching during system
startup.
Caller ID Receiving
Select as None, FSK or DTMF for receiving caller ID digits. For North
America, the caller ID is FSK signal on analog trunk.
Centrex Flash Duration (ms)
Specifies the Flash Duration time in milliseconds, with a range from 150
ms to 1000 ms.
Out of Service With Trunk
Seizure
When checked, if the trunk is set to Out of Service, the system will busy
out the trunk. The CO will treat this trunk as a busy line and WILL NOT
place a call to this trunk. (By default, this option is unchecked.)
Enable Dial Tone Detection
(Outgoing) When enabled, the trunk channel must detect outgoing dial tone prior
to making the call.
Enable Answer Debounce
(Incoming) Enables a timeout period of 2 seconds (for ignoring false CO
disconnect signal), after answering an incoming call.
Loop Break Duration (ms)
Disconnects signal if CO breaks loop current. You can set the duration
from 200 to 1000 ms. 600 ms is common in North America.
Tone Disconnect
Busy tone (reorder tone, fast busy tone, error tone, and so on) or dial
tone (continuous tone, and so on). This should be used in conjunction
with drop in loop current. For COs who cannot guarantee loop break,
this may be the only option.
Receiver/Transmission Gain
Slide setting adjusts the gain from -6 dB to 6 dB for every Triton Analog
Trunk channel.
The gain is not adjustable, by default. The user needs to run the
diagnosis first to change the gain. The diagnosis process determines
the max gain based on the diagnosis results.
The default setting is
0 dB , and it is highly recommended that you not
change this setting.
Caution!
Setting the volume too high will cause distortion in voice
quality and/or missed DTMF digits.
Trunk to Trunk Gain
This configuration is to set Gain for calls that involve two analog trunks
(one in and one out). Because an analog trunk typically has energy loss
of 3-12 dB, a two-trunk operation, like VM out call and MobileExt, may
have low volume issues because energy loss is doubled. This configu-
ration can compensate for the energy loss. The valid range is 0 to 6 dB.
Recommended value is 3 dB.
Caution : Setting the Gain too high may cause distortion in voice quality
and DTMF tone. Your CO may not be able to recognize the dialing
number if DTMF tones are distorted.
Last Diagnosis Time The last time the Diagnosis button was clicked.
Diagnose button
Use this button to view the Noise Level, Echo Return Loss, and Hybrid
Echo Return Loss, measured using the current Impedance setting.
Noise Level
The noise level (displayed after you click the Diagnose button or the
Match Impedance
button). Acceptable range for Noise Level is less
than -67 dBm in value. For example, Noise Level of -72 dBm is good
and -63 dBm is poor. You may experience high background noise and
low voice volume if Noise Level is poor.
Echo Return Loss
The measurement for echo return loss (displayed after you click the
Diagnose
button or the Match Impedance button). Acceptable range
for Echo Return Loss is less than -12 dB. For example, Echo Return
Loss of -19 dB is good and -8dB is poor. The IP phone users may hear
their voice coming back (echo) if Echo Return Loss is poor.
