Chapter 12: Trunk Configuration
162 AltiWare ACM 5.1 Administration Manual
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
configuration can compensate 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 tone is 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.
Hybrid Echo Return
Loss
The measurement for hybrid echo return loss (displayed
after you click the Diagnose button or the Match
Impedance button). Acceptable range for Hybrid Echo
Return Loss is less than -6 dB.
