90 Call Forward All Calls
When you use Multiple Appearance DNs (MADNs), call redirection is
determined based on the Terminal Number (TN) order in your DN block. To
determine the TN order, print the DN block from LD 20 or LD 22 (TYPE =
DNB). When a call comes in to an MADN, the system begins a search
to determine how the call is handled. Using the TN list you printed, the
system performs the following search, beginning at the bottom of the TN
list, and working up.
1. Searches for the first Prime DN appearance of the MADN with Call
2. If there are no Prime DN appearances, the Call Forward All Calls cannot
The search does not necessarily determine the lowest numerical TN. The
search starts at the bottom of the TN list.

Operating parameters

The forwarding of a call depends on the access limitations assigned to the
telephones and the trunks involved in the call. If call forwarding results in
a connection that is not permitted by the assigned access limitations, the
incoming call is not forwarded.
The customer can specify which telephone determines the successful
completion of the call: the originating telephone or the forwarding telephone.
Internal Call Forward requires a programmable feature key. Therefore,
Internal Call Forward is not supported on BRI telephones.
LD 17 CFWS allows telephones to have their CFW status saved as part of
the data dump routine and then reinstated following a SYSLOAD. For more
information, refer to the Call Forward Save feature RL.
Call Forward Reminder Tone does not apply to telephones that have a visual
indication of active CFW status.
The Reciprocal Call Forward All Calls option prevents the situation whereby
an infinite loop is caused in a network-wide Call Forward configuration
resulting from telephone A being call forwarded (all calls) to telephone B at
another node, which in turn has been call forwarded back to telephone A.
A check is provided using the Flexible Orbiting Prevention Timer (FOPT),
which prohibits any telephone from call forwarding more than one call off
node for a period of 14 seconds.
