Chapter 12: Trunk Configuration

Parameter	Description
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/	Slide setting adjusts the gain from -6 dB to 6 dB for every
Transmission Gain	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	The measurement for hybrid echo return loss (displayed
Loss	after you click the Diagnose button or the Match
	Impedance button). Acceptable range for Hybrid Echo
	Return Loss is less than -6 dB.
