1093 Call Forwarding Don't Answer After Call Waiting (CFDA After CW)

Call Forwarding Don't Answer After Call Waiting is a central office software
capability that allows a client to utilize the Call Forwarding Don't Answer
(CFDA) feature even though the client's line is also equipped with Call
Waiting (CW).

CFDA/CW interaction was initially designed for CW to be dominant over CFDA.
For a busy line equipped with both features (CFDA and CW), receiving an incoming
call invoked the CW tone, but did not transfer to the CFDA forward-to number.
This resulted in the CFDA feature being effective only when the line was not
busy and not answered.

* This capability is inherent with Call Forwarding Don't Answer in switches
  which have been modified.  Check wire center deployment report for 
  availability.

FEATURE OPERATION:
The new feature interaction allows a client to subscribe to both CFDA and CW,
and receive the benefits of both features.  An incoming call to a busy line
will invoke the CW tone.  The client can place the existing call on hold and
answer the call, or by not answering the call, can allow the CFDA feature to
assume control of the new call and transfer it to the CFDA forward-to number.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. This feature is available in the following central office switches:

Switch Type			1A ESS		5ESS	DMS-100
Earliest Generic Release	1AE10.11	5E7	BCS32

2. This feature is activated on a office basis.  The AT&T switches (1A ESS and 
   5ESS) have a line-by-line override parameter to accommodate any customer
   situations where the capability may not be desired.  

3. In the DMS-100 switch, the feature only affects those CFDA and CW customers 
   served by RES.  There is no line-by-line override parameter in the DMS-100 
   switch.

4. The line specific CFDA features (number of rings, inter/intraoffice 
   forwarding) will operate the same as though the line were on-hook and not 
   answered.

5. Standard CFDA and CW operation applies.

6. References: not available

This service, if offered as a BSE, is associated with the Circuit Switched Line
basic serving arrangement.
