144 Call Forward No Answer, Second Level
Call Forward by Call Type
To implement Call Forward by Call Type for Second Level Call Forward No
Answer eligible calls, the originating party's call type is checked. If it is
internal, the call is forwarded to the Flexible Call Forward No Answer DN
(FDN). If it is external, the call is forwarded to the External Flexible DN
(EFD).
Call Forward No Answer
Second Level Call Forward No Answer applies to the Hunt and Flexible Call
Forward No Answer options. This is implemented by defining the FNAD,
FNAT, or FNAL prompts in LD 15 as FDN or HNT. If the attendant option is
defined, an unanswered call goes to the attendant queue and is not eligible
for Second Level Call Forward No Answer.
Call Redirection by Time of Day
Existing Second Level CFNA allows unanswered calls to receive Call
Forward No Answer treatment twice. Call Redirection by Time of Day
(CRTOD) parameters are obtained from the last rung Directory Number. A
maximum of two levels of CFNA is allowed for an unanswered call.
Call Waiting Redirection
The existing Second Level CFNA treatment is applicable to Call Waiting
calls redirected by CFNA (first level) with the Call Waiting Redirection
feature which are still not answered at the last rung DN.
Calling Party Privacy
When an incoming trunk call with the Privacy Indicator is forwarded, the
Privacy Indicator is tandemed to the far end to inhibit the display of the
Calling Party Name or Number provided that the tandem node also has
Calling Party Privacy (CCP) provisioned.
If an incoming non-ISDN trunk call is forwarded to a trunk, the outgoing
trunk call from the tandem node will carry the Privacy Indicator if the
outgoing trunk route on the tandem node has the TCPP option set.
The CCP code can also be stored on the forwarding DN. If the CPP is
requested on the forwarding DN, the Privacy Indicator is outpulsed to the
terminating node to inhibit the number of the forwarding telephone (for
example, at the tandem node) from being displayed on the terminating
telephone. In this case, the forwarding station must include the CPP in the
forwarding DN (such as *67 + ACOD + the DN on the terminating node).
Directory Number Delayed Ringing
The Directory Number Delayed Ringer (DNDR) feature allows the SCN/MCN
(non ringing keys) to actually ring after a definable period of time (DNDR
prompt in LD 11). If the time before CFNA takes effect is less than the
