Alternate Operations Support System Alarm
Number
Allows you to establish a second number for the system to call when an alarmable
event occurs. This feature is useful for alerting a second support organization,
such as INADS or OneVision.
Answer Detection
For purposes of call-detail recording, it is important to know when the called party
answers a call. The system provides three ways to determine whether the far end
has answered an outgoing call.
■ Network Answer Supervision — The central office (CO) sends back a
signal to indicate that the far end has answered the call. If a call has
traveled over a private network before reaching the CO, the signal is
transmitted back over the private network to the originating system. This
method is extremely accurate, but is not available in the United States over
CO, FX, or WATS trunks.
■ Answer Detection — A call-classifier circuit pack detects tones and
voice-frequency signals on the line and determines whether a call has
been answered. This method is fairly accurate.
■ Answer Supervision by Timeout — A timer is set for each trunk group. If the
caller is off-hook when the timer expires, the system assumes that the call
has been answered. This is the least accurate method. Calls that are
shorter than the timer duration do not generate call records, and calls that
ring for a long time produce call records whether they are answered or not.
Attendant Auto-Manual Splitting
Allows an attendant to announce a call or consult privately with the called party
without being heard by the calling party on the call. It splits the calling party away
so the attendant can confidentially determine if the called party can accept the
call.
Attendant Backup
Notifies backup attendants that the primary attendant cannot immediately pick up
a call. It provides both audible ringing and visual alerting to backup stations when
the attendant queue reaches its queue warning level. When the queue drops
below the queue warning level, alerting stops. Audible alerting also occurs when
the attendant console is in night mode, regardless of the attendant queue size.
