COVERAGE OF CALLS REDIRECTED
OFF-NET (CCRON)
Activate Answer Detection (Preserves SBA)
On Final CCRON Cvg Point
This field appears only if the
Coverage of Calls Redirected Off-Net Enabled
field on this screen is y.
When the system redirects a call off-net at the final coverage point in a coverage path, the system can
apply no further coverage treatment even if the call is unanswered. The only reason for activating answer
detection on such a call is to maintain the simulated bridged appearance (SBA) on the principal’s phone
that allows the principal to answer or bridge onto the call. However, when the system monitors the call
through use of a call classifier port, there is an inherent cut-through delay following the detection of
answer at the far end. This field has no consequence when the off-net call is carried end-to-end by ISDN
facilities; the SBA is maintained and there is no cut-through delay.
Coverage Of Calls Redirected Off-Net Enabled
This field allows you to enable/disable the Coverage of Calls Redirected Off-Net (CCRON) feature. This
field provides a quick means of disabling this feature if the demand on the call classifier port resources
degrades other services provided by Communication Manager.

Usage
y
Directs the system to maintain a simulated bridged appearance on
the principal when redirecting to a final off-net coverage point.
n
Allows the system to drop the SBA on the principal’s phone when
the call redirects off-net at the last coverage point, eliminating the
cut-through delay inherent in CCRON calls, but sacrificing the
principal’s ability to answer the call.
