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.

Signaling
DID E&M
WinkStart
Immediate
DelayDial
Select the signal type for the line. The immediate setting does
not appear for T1 E&M or T1 DID trunks connected to a DTM if
the Dial mode is set to tone.
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.
