Feature interactions 297
When a second call goes to a telephone that already has a Call Waiting
call, the second call is recalled to the attendant if it is not answered by the
number of rings defined in the Customer Data Block (RTIM prompt, field zz).
An analog (500/2500 type) telephone user who has received a Call Waiting
call routed from the attendant cannot reconnect to the original call until it
has been released from the console.
Attendant Administration does not support the Internal Call Waiting feature.
If a call is waiting and Call Waiting is deactivated using the Call Waiting
Deactivate (CWGD) FFC, the call that is waiting is allowed to continue
waiting while any new calls will not be allowed to wait.

Advice of Charge for EuroISDN
When an Advice of Charge call is transferred to a busy set with Call Waiting
Allowed, the transferring station is charged until the call is answered.
Attendant Blocking of Directory Number
If a set that has the Station-to station Call Waiting feature active (CLS SWA
and a Call Waiting (CWT) key for digital sets) is idle when an Attendant
Blocking of DN attempt is made, the Attendant Blocking of DN attempt is
allowed and processed as normal. If the DN is idle and there is an active
call on the Call Waiting key, the Attendant Blocking of DN attempt is allowed.
If a set has the Station-to-station Call Waiting feature active and the DN to
be blocked is busy when an Attendant Blocking of DN attempt is made, the
Attendant Blocking of DN attempt is canceled and busy tone is returned.
For a set that has the Call Waiting (or Station-to-station Call Waiting) feature
active and a DN is blocked due to the Attendant Blocking of DN feature, any
incoming call to the blocked DN will receive busy tone.
Attendant Break-In
If the destination DN has a camped-on incoming trunk call, the attendant
cannot extend the urgent incoming call as a Camp-On call.

Attendant Incoming Call Indicators

The ICI feature is used with the Call Waiting feature to recognize, answer,
