FEATURE OPERATION:
This feature is activated/deactivated by the customer dialing an activation 
code and the remote DN or the deactivation code.  The codes are in the same 
format as Call Forwarding Variable (*XX). 

Customer control of Call Forwarding Busy Line/Don't Answer is a central office
software capability that allows a subscriber to have an incoming call redirected
to another Directory Number (DN) if the number dialed (the subscriber's number)
is in a busy condition or is not answered.  The service is activated by the 
subscriber dialing an activation code, much in the same manner as Call 
Forwarding Variable, and entering the remote number that calls will be forwarded
to.  The called number and the redirected number do not have to be in the same 
switch.  The service and forwarded-to number are deactivated by dialing the 
deactivation code.

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	1AE10.09*	5E2(2)	BCS27

* References to switching system generics that have not yet been released by the
vendors are based on our current information about which features are planned 
for inclusion in those generic releases.  If the vendors change the availability
of any features for future generic releases that are referenced in this 
document, the availability of some services may be affected.

2. Multiline customers can have CFBL/DA - Customer Control on each line
   if desired.

3. The maximum number of digits that can be programmed are:
   1A ESS - 16 digits
   5ESS - 24 digits
   DMS-100 - 24 digits

4. Subscribers may have CFBL with CFDA, Call Forwarding Variable (CFV), and
   Call Waiting (CW).  If a station has CFV and CFBL or CFDA active, then CFV
   will override the CFBL and/or CFDA features.  In the 1A ESS Call Waiting
   takes precedence and does not interact with CFBL.  Un-answered Call Waiting
   calls do not revert to CFDA in either the 1A ESS or the 5ESS.
