5005 Call Waiting (NYNEX Region Specific)

The Call Waiting (CW) feature informs a busy station user, by a burst of tone, 
that another call is waiting.  The busy station user may hang up and answer the
second call or can place the original call on hold and answer the second call.

FEATURE OPERATION:
An incoming call to a busy line with CW receives audible ringing.  The line
with Call Waiting receives a CW tone that is repeated once about 10 seconds
after the initial burst of tone.

The line with CW may respond to the CW tone in one of three ways.  The called
party may disconnect from the existing call.  The telephone will then be rung 
and, if answered, the called party will be connected to the waiting call.  The 
second alternative allows the line with Call Waiting to flash the switch-hook 
(.75 to 1.5 seconds) and, thereby, place the original call on hold and connect
to the incoming call.  The party with CW may alternate between calls by flashing
the switch-hook.  The third alternative is not to respond to the CW tone. 

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	1AE8	5E2	BCS17

2. If a line has Call Forwarding Busy Line (CFBL) and CW, the CW service
   normally takes precedence.

3. Given that a line has both CFBL and CW and is in the talk state, the
   first call attempting to terminate is treated as a CW call.  Subsequent
   termination attempts are call forwarded.

4. On a line with both a make-busy key and CW, make-busy key takes 
   precedence when the key is activated.
