AltiGen comm ACM 5.1 Parameter Description Incoming Ring, Caller ID Receiving, Centrex Flash

	Chapter 12: Trunk Configuration
Parameter	Description
Incoming Ring	Single—Default setting for North America
	Double—For countries using Ring-Ring-Silent type of ring
	pattern
Impedance	The resistance of electrical current to alternating current,
	measured in Ohms. Impedance occurs when power or
	signal is transferred from one circuit to another. When a
	trunk interface impedance is greatly mismatched with the
	CO analog line, it may result in static noise and echo heard
	by IP phone users. The system automatically selects the
	impedance profile that best matches the Triton trunk
	interface with the CO. In the rare case where you are not
	getting the best match, you can disable this feature by
	checking Disable Impedance Match During System
	Startup, and you can set the Impedance manually.
Match Impedance	Changes the Impedance setting to the best match for the
button	selected trunk channel, and then measures noise and
	returned echo with this impedance setting. Results are
	displayed in the Diagnosis section of the dialog box. The
	system automatically runs a matching test upon system
	startup, unless you disable the feature. If later you
	connect a new analog line to an empty port or replace an
	existing line, you need to click this button to best match
	the impedance.
Match Result button	Shows the result obtained the last time the Match
	Impedance button was clicked for that trunk.
Disable Impedance	Check to disable automatic impedance matching during
Match During System	system startup.
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	Specifies the Flash Duration time in milliseconds, with a
Duration (ms)	range from 150 ms to 1000 ms.
Out of Service With	When checked, if the trunk is set to Out of Service, the
Trunk Seizure	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	When enabled, the trunk channel must detect outgoing
Detection (Outgoing)	dial tone prior to making the call.
Enable Answer	Enables a timeout period of 2 seconds (for ignoring false
Debounce (Incoming)	CO disconnect signal), after answering an incoming call.
Loop Break Duration	Disconnects signal if CO breaks loop current. You can set
(ms)	the duration from 200 to 1000 ms. 600 ms is common in
	North America.
