Chapter 1 Solution Overview
Solution Features
Automatic Callback (AC) – Repeat Dialing
AC, also called repeat dialing, allows the user to request the system to automatically call the most
recently dialed number. The system will keep attempting to call the number for up to 30 minutes, and
the remote station will be rung automatically when the called party becomes idle. The system alerts the
user with distinctive ringing. Up to 20 AC requests can be active at any time. The service provider can
set up this service for the user, or the user can access it on a usage-sensitive basis.
Automatic Recall (AR) - Call Return
AR, also called Call Return, allows the user to request the system to automatically redial of last incoming
call (that is, the station that called the user) when that station becomes idle. The system will keep
attempting to call the number for up to 30 minutes, and the remote station will be rung automatically
when the called party becomes idle. The system alerts the user with distinctive ringing. Up to 20 AR
requests can be active at any time. The service provider can set up this service for the user, or the user
can access it on a usage-sensitive basis.
Call Block (Reject Caller)
The call block (reject caller) feature allows the user to block incoming calls from the DN of the last
received call. For the call block feature to work, the user must already be subscribed to the selective call
rejection (SCR) feature. Once call block is activated against a specified DN, that DN remains in the SCR
list of the subscriber. A subscriber who wishes to block callers (like sales calls, etc.) but does not know
the caller's DN, can use this feature. Call block can be provided to POTS, CENTREX and MLHG
subscribers.
The user can deactivate call block for this DN by removing the DN from their SCR list. This is done by
using the screen list editing (SLE) function of the SCR feature.
Call Waiting (CW)
CW informs a busy station that another call is waiting through the application of a 300 ms, 440 Hz tone.
Ten seconds after the initial tone, a second tone is applied if the waiting call has not been answered. To
answer the waiting call and place the original call on hold, the user presses the Flash button or
hookswitch. A subsequent flash returns the user to the original call. Additional flashes can be used to
toggle between the two calls as long as they are both still connected. The waiting call hears ringing until
it is answered.
When a waiting call is accepted, there are two active sessions. To end the currently active session, the
user goes on hook. The user’s phone will then ring to indicate that the other caller is still holding. The
user can pick up the phone to resume that session.
Only one instance of CW can be active for a given subscriber line at any given time. Thus, if a subscriber
line were involved in both an active call and a waiting call, then an additional incoming call attempt
results in the caller receiving a busy tone or being forwarded (CFB). The user involved in the CW call
is not aware of the additional incoming call attempt.
Cancel Call Waiting (CCW)
CCW allows a user to disable CW, which also disables the calling identity delivery/call waiting
(CIDCW) feature for the duration of a call. CCW is normally included as an integral part of a service
package containing the CW and CIDCW features. CCW is useful when the user does not want to be
interrupted during an important call or during an outgoing data/fax call. After the current call is
completely released, the CW service will be back in effect automatically.
