Attribute Value Description

Legend: Loop = analog/digital loop; GS = ground start; DID = DID; E&M = E&M; BRI = BRI; DPNSS

= DPNSS; VoIP = VoIP; TL = Target. Note: PRI fields are all included under the main table.

Signaling		DID	E&M
	WinkStart		Select the signal type for the line. The immediate setting does
	Immediate		not appear for T1 E&M or T1 DID trunks connected to a DTM if
			the Dial mode is set to tone.
	DelayDial
			Make sure that this matches the signal type programmed for the
			trunk at the other switch.

Link at CO	Loop (analog
	only)
	<check box>	Some exchanges respond to a Link signal, also called hook
		flash (FEATURE 71), by providing an alternative line for making
		outgoing calls.
		Enabling Link at CO causes the system to apply the restrictions
		on outgoing calls to the digits dialed after the Link signal. As
		well, the call on the alternative line is subject to all restrictions.
		Disabling Link at CO prevents a Link signal from resetting the
		BCM450 restrictions in cases where the host exchange does
		not provide an alternative line.
Line Tuning Digit	drop-down menu	Select the line tuning digit to use. When a trunk is connected,
		the BCM450 starts a call and sends this digit to the CO to turn
		off the dial tone signal, and then tests the line to optimize the
		trunk levels. The default digit is 1. You may need to change the
		default digit if your CO uses the digit 1 to route the call to a
		special service or to a second dial tone or busy/re-order tone.
		Select the digit that will result in silence on the trunk.

Preferences

The Preferences tab shows information that may vary from trunk to trunk. Most of this information needs to coordinate with the line service provider equipment.

The Preferences tab is shown in Figure 11.
