152 Call Forward No Answer/Flexible Call Forward No Answer
telephone that does not answer within the specified number of ring cycles
is forwarded to the Flexible Call Forward No Answer DN (FDN) associated
with that telephone.
The Flexible Call Forward No Answer operation applies only to individual
DN calls of analog (500/2500 type) telephones, and not to Automatic Call
Distribution (ACD) calls.
A call is forwarded under the following conditions:
The Class of Service of the dialed telephone is Forward No Answer
allowed.
Flexible Call Forward No Answer is enabled at the customer level.
The call has rung the specified number of times.
The Call Forward No Answer DN (FDN) is valid and has been assigned.
System or telephone features such as Hunting and Call Forward All Calls
may result in the presentation of a call to a telephone that is different from
the dialed DN. In these cases, if the call is eligible for Flexible Call Forward
No Answer, it is forwarded to the DN specified for the dialed DN, not the
ringing DN.
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 a 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.
Step Action
1Search for the first Prime DN appearance of the MADN with Call
Forward All Calls activated.
2If there are no Prime DN appearances, the TN at the bottom of the
list controls call redirection.
The search does not necessarily determine the highest or lowest
numerical TN.

Calls are forwarded one step only. For Call Forward No Answer
