AltiGen comm ACM 5.1 manual Receive from CO, DB Gain

Chapter 12: Trunk Configuration

Parameter	Description
Incoming Ring	Single—Default setting for North America
Type	Double—For countries using Ring-Ring-Silent type of ring
	pattern
Centrex Flash	Specifies the Flash Duration time in milliseconds, with a range
Duration (ms)	from 50 ms to 1000 ms. This setting complements the Centrex
	Flash Support option in the General tab for the trunk.
Detect Trunk	When selected, the analog trunk will check the loop current
Status By Loop	and if connected will change the state to “Idle.” If not selected,
Current	the trunk will check circuit DC voltage to determine the trunk
	status. Do not change this setting without consulting with
	AltiGen Technical Support.
Enable Caller ID	When selected, the system will wait for caller ID FSK signal
Receive	before answering the incoming call. In North America,
	typically it takes two rings to receive the caller ID from the CO.
	If your trunk does not have caller ID service, you can uncheck
	this box to speed up the answering process.
Out of Service With	When checked, if the trunk is set to Out of Service, the system
Trunk Seizure	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.)
Call Setup	Select from:
	• 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.
Disconnect	Select from:
Supervision	• Tone—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.
	• Polarity Reversal—a reversed battery signal.
	Loop Break Signal either 200 or 600. 600 ms is common
	in North America.
Receive from CO	Slide setting adjusts the gain from the CO to the trunk from
(dB Gain)	0 dB to 7 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.
