    							Answer Detection
    Issue  3   March 1996
    3-97
    Answer Detection
    Feature Availability
    Answer Detection is available with all Generic 3 releases except G3vs/G3s ABP. 
    Description
    Improves the accuracy of the call duration in CDR call detail record s by 
    detecting the state of outgoing trunk calls that do not receive Network Answer 
    Supervision.
    A timer is used to d etermine when the called party has answered. Since Network 
    Answer Supervision may or may not be sent back, a normal outgoing trunk call 
    without the Answer Detection feature relies upon the Far End Answer 
    Supervision timer once an outgoing call is placed.
    The Far End Answer Supervision timer is an internal, a dministrable timer that 
    estimates when the far end should have answered the call. The interval for the 
    Far End Answer Supervision timer is specified on the ‘Trunk Group’ form. As soon 
    as the specified Far En d  Answer Supervision time interval is reached, CDR 
    generates a call detail record. However, if the call terminates before the timeout 
    interval is reached, CDR does not generate a call detail record .
    Answer Detection allows the system administrator to set the answer supervision 
    timeout to larger values while g enerating CDR call d etail reports on short d uration 
    calls.
    The Answer Detection feature uses a port on the Call Classifier circuit pack to 
    detect various tones and voice-frequency signals received from the outgoing 
    trunk, and classifies the call as answered, unanswered, busy, etc. based on this 
    tone detection.   A call that has been classified as answered by this tone 
    detection c a pability is assumed to have been answered for the purpose of 
    generating a CDR call record, even if Network Answer Supervision has not been 
    received and/or the Far En d Answer Supervision timer has not been timed out.
    This provides a more accurate time of call duration and therefore imp roves Call 
    Detail Recording and any subsequent billing based on CDR records. 
    NOTE:
    A CDR call record is generated if a call classifier is involved and the call is 
    classified prior to the Far End Answer Supervision timer expiring. 
    						
    							Feature Descriptions
    3-98Issue  3   March 1996 
    Considerations
    The Answer Detection feature does not accurately detect all types of tones 
    especially in countries whose tone schemes are not similar to the US. For a 
    normal answered call, the call will usually be correctly classified as answer. 
    However, some calls may be misclassified as Fast Busy when they are actually 
    answer. Miscellaneous tones, such as the PBX tones (that is, confirmation) will b e 
    classified as answer. In addition, loud background noise may activate Answer 
    Detection, causing the call to be classified as answer, even if the call is not 
    connected. If Answer Detection is accidentally activated, but the call is not 
    connected, the call is recorded in CDR records on the PBX. If Answer Detection 
    is accidentally a ctivate d and the call is connected, the caller is b illed erroneously 
    for the time that elapses between Answer Detection activating and the called 
    party answering.
    Administration
    While Answer Supervision is a system-wide option, the timer interval that a p plies 
    to a particular trunk must be administered on a trunk group basis. Only trunks 
    administered as CO, FX, or WATS trunks receive this treatment.
    Interactions
    The following features interact with the Answer Detection feature.
    nCallVisor ASAI
    Answer Detection competes with CallVisor ASAI switch-classified calls for 
    ports on the Call Classifier circuit pack. Answer Detection triggers 
    reporting of a Connect Event to ASAI.
    nCall Promp ting
    Answer Detection comp etes with Call Promp ting for ports on the Call 
    Classifier circuit pack.
    nCDR 
    Answer Detection provides more accurate CDR records where tone 
    detection is possible and Network Answer Supervision is not received. 
    Answer Detection trig gers reporting of a Connect Event to ASAI. 
    Hardware and Software Requirements
    Requires a TN744 Call Classifier circuit pack. 
    						
    							Attendant Auto-Manual Splitting
    Issue  3   March 1996
    3-99
    Attendant Auto-Manual Splitting
    Feature Availability
    This feature is available with all Generic 3 releases.
    Description
    Allows the attendant to announce a call or consult privately with the called party 
    without being heard by the other party on the call.
    This feature is activated automatically when the attendant, active on a call, 
    presses the S
    TART button, a Hundreds Select button and a Direct Extension 
    Selection button (if provided), or a Trunk Group Select button. Any of these 
    actions temp orarily separates the party on the call from the connection and 
    allows the attendant to call and talk privately with another party.
    The connection is reestablished when the attendant presses one of the following 
    buttons:
    nCancel — Cancels the call attempt and reconnects the attendant and the 
    separated party.
    nSplit — Esta blishes a three-way conversation with the attendant, the 
    separated party, and the called party.
    nRelease — Connects the separated party and the called party and 
    disconnects the attendant.
    Considerations
    Attendant Auto-Manual Splitting provides for splitting the calling party away so 
    attendant can confidentially determine if the called party can accept the call.
    Administration
    To use Auto-Manual Splitting, one SPL I T button must be assigned per console 
    and “Auto Start’’ must b e  disabled on ‘‘System Parameter’’ form for G3i-Global, 
    G3rV1, G3V2, G3V3, G3V4, and later releases.
    Hardware and Software Requirements
    No a d ditional hardware or software is required.

    3-100Issue  3   March 1996 
    Attendant Call Waiting
    Feature Availability
    This feature is available with all Generic 3 releases.
    Description
    Allows an attendant originated or extend e d calls to a busy single-line voice 
    terminal to wait at the called terminal.  The attendant is free to handle other calls.
    Attendant Call Waiting is activated for a single-line station whenever an attendant 
    originates or extends a call to a busy single-line voice terminal. The attendant 
    hears a Call Waiting ringback tone and the busy voice terminal user hears a call 
    waiting tone. This burst tone is heard  only by the called voice terminal user. The 
    number of bursts (one, two, or three bursts) is administrable in G3i-Global, G3V2; 
    and later releases.
    When the Attendant Call Waiting is a ctivate d the attendant may choose to c ancel 
    the call, release the call, or hold the call on the console. However, releasing an 
    attendant-originated call results in the call being dropped completely. If the 
    attendant activates the Attendant Call Waiting feature, and the administered 
    Return Call Time-Out or Time d Reminder on Hold interval expires without the call 
    being answered, the call returns to the console.
    The call in progress at the voice terminal can be placed on hold. In order to 
    answer the waiting call, after receiving recall dial tone, the user then d ials the 
    answer call waiting access code. After answering the waiting call, the voice 
    terminal user can use the Hold feature to return to the held call or toggle back 
    and forth b etween the two calls.
    As an example of how Attendant Call Waiting is used, assume extension 123, a 
    single-line voice terminal, is b usy.  An attendant extends a call to extension 123 
    and hears the Call Waiting Ringback Tone which indicates that Attendant Call 
    Waiting is activated.  The attendant may choose to announce the call waiting 
    condition to the calling party. However, after d oing this, the attendant cannot 
    cancel the call. The attendant could cancel the call and ask the calling party to 
    call again later, or the attendant could release the call or place the call on hold at 
    the console. This allows the attendant to handle other calls.  The voice terminal 
    user at extension 123 hears a two-burst tone and knows a call is waiting.  The 
    voice terminal user at extension 123 can then terminate the call in progress, or 
    place the call in progress on hold, and answer the waiting call.  If the waiting call 
    is not answered before a preassigned time interval (Return Call Timeout or Time d 
    Reminder on Hold) expires, the call returns to the attendant. 
    						
    							Attendant Call Waiting
    Issue  3   March 1996
    3-101
    Considerations
    Attendant Call Waiting allows an attendant to originate or extend calls to a busy 
    single-line voice terminal while allowing the attendant to handle other calls.  
    Since the attendant is able to handle other calls while a c all is waiting, more c alls 
    can be answered.
    Attendant Call Waiting a p plies only for calls to single-line voice terminals within 
    the system. Only one call per voice terminal can wait at a time.
    Interactions
    The following features interact with the Attendant Call Waitin g  feature.
    nAutomatic Callback
    If Automatic Callback is activated at the called voice terminal, Attendant 
    Call Waiting is denied.
    nCall Coverage
    Attendant Call Waiting  calls can be redirected to coverage if the called 
    voice terminal has Data Privacy or Data Restriction activate d. If one of 
    these conditions exist, and
    nCall Coverage is assigned to a voice terminal, and
    nSend All Calls is activated or coverage criteria are met,
    the call does not wait and can be redirected to the coverage path.  In 
    some cases, the call can wait and then be redirected to coverage.  In 
    other cases the call returns to the console, rather than be redirected to 
    coverage.  The operation is as follows:
    — The Coverage Don’t Answer interval (two to nine ringing cycles or 
    the equivalent time) specifies how long a call remains directed to 
    the called voice terminal b efore redirecting to coverage.  This 
    interval a p plies to b oth the Busy and Don’t Answer criteria. If 
    Attendant Call Waiting is a p plicable on the call, this feature is active 
    for the duration of the Don’t Answer interval only.  At the expiration 
    of this interval, the call redirects to coverage.
    — If the Return Call Timeout (Timed Reminder) interval expires before 
    the Don’t Answer interval expires, the call does not go to coverage 
    but returns to an attendant console.  If the Don’t Answer interval 
    expires first, the call redirects to coverage, but can still return to the 
    attendant console if a coverage point does not answer the call 
    before the Return Call Time-out. 
    — If Send All Calls is active or if the redirection criterion is Cover All 
    Calls, the call immediately redirects to coverage instead of waiting.
    — An attendant can release from an extended call at any point during 
    the call, without affecting the preceding operations.

    3-102Issue  3   March 1996 
    nData Privacy
    If Data Privacy is activated at the called voice terminal, Attendant Call 
    Waiting is denied.
    nData Restriction
    If Data Restriction is activated at the called voice terminal, Attendant Call 
    Waiting is denied.
    nDDC and UCD
    Calls to a DDC or UCD group do not wait; however, such calls can enter 
    the group queue, if provided.
    nLoudspeaker Paging Access
    If Loudspeaker Paging Access is activated at the called voice terminal, 
    Attendant Call Waiting  is  denied.
    nMusic-on-Hold Access
    Music-on-Hold can be heard by the calling party, if the call is a trunk 
    transferred call and this typ e of call is administered to receive 
    Music-on-Hold for call waiting calls.  Otherwise, the calling party does not 
    hear Music-on-Hold, but hears ringing.
    nRecorded Telephone Dictation A ccess
    If Recorded  Telephone Dictation Ac cess is activated at the called voice 
    terminal, Attendant Call Waiting is denied.
    nTimed Reminder
    The Timed Reminder interval d etermines how long a call waits before 
    returning to an attendant console.  If the call is not answered or does not 
    redirect to coverage before this interval expires, the call returns to the 
    attendant console.
    Administration
    Attendant Call Waiting is a standard system feature. Attendant Call Waiting is 
    assigned to single-line voice terminals on a per-terminal basis.   The call waiting 
    interval is administered through the Time d Reminder and Attendant Timers 
    feature by the System Manager. Also, transferred trunk calls that are waiting to 
    be answered can be administered to receive Music-on-Hold.
    Hardware and Software Requirements
    No a d ditional hardware or software is required. 
    						
    							Attendant Control of Trunk Group Access
    Issue  3   March 1996
    3-103
    Attendant Control of Trunk Group 
    Access
    Feature Availability
    This feature is available with all Generic 3 releases.
    Description
    Allows the attendant to control trunk groups, and prevents voice terminal users 
    from directly accessing a controlled trunk group.
    Each attendant console has 12 designated Trunk Hundreds Select buttons to be 
    used with the Attendant Direct Trunk Group Selection feature. Each console 
    may have up to 12 of its feature b uttons administered as additional Trunk 
    Hundreds Select buttons, for a total of 24 Trunk Hundreds Select b uttons per 
    console. The attendant gains direct access to an outgoing trunk group by merely 
    pressing the button assigned to that trunk group.
    All Trunk Hundreds Select buttons (including any administered on the console’s 
    feature b uttons) have a Busy lamp  which lights when all trunks in the associated 
    trunk group are busy.  If one of the two-lamp feature buttons on a basic console 
    is administered as a Trunk Hundreds Select b utton, the bottom lamp  is used as 
    the Busy lamp (the top lamp is not used).  Six of the designated buttons (basic 
    console) or all 12 designated buttons (enhanced console) have two a d ditional 
    lamps that are used for Attendant Control of Trunk Group Access.  The two 
    a d ditional lamps are as follows:
    nWarn (warning) lamp
    Lights when a preset numb er of trunks are busy in the associated trunk 
    group (the busy threshold of the trunk group is reached).
    nCont (control) lamp
    Lights when the attendant activates Attendant Control of Trunk Group 
    Access for the associated trunk group.
    The attendant activates Attendant Control of Trunk Group Access by  pressing a 
    C
    ONT ACT (Control Activate) button followed by the d esired Trunk Hundreds 
    Select button. The Trunk Group Select b utton used must have a Cont. (control) 
    lamp. If a user attempts to access a controlled trunk group directly, the call 
    automatically redirects to the attendant.  If the attendant decides to allow the call 
    to go through, the attendant can connect the user to the desired trunk group by 
    pressing the associated Trunk Group Select  button.   The  attendant can then 
    release the call or hold the call on the console.
    Calls already in queue for a trunk are not affected by the activation of Attendant 
    Control of Trunk Group Access for that trunk group.  For example, if an attendant  
    						
    							Feature Descriptions
    3-104Issue  3   March 1996 
    activates Attendant Control of Trunk Group Access for a specific trunk group 
    while a user is waiting in queue for an outside trunk in that trunk group, the call is 
    not affected .  The call remains in queue until an idle trunk becomes available, at 
    which time the call is connected to that idle trunk.
    The attendant deactivates Attendant Control of Trunk Group Access by pressing 
    the C
    ONT DEACT (Control Deactivate) button followed by the desired Trunk 
    Hundreds Select b utton. [The Trunk Group Select button used must have a Cont. 
    (control) lamp.] Attendant Control of Trunk Group Ac cess is activated and 
    deactivate d separately for each trunk group.
    After an attendant presses a C
    ONT ACT or CONT DEA C T button, the attendant can 
    perform other operations before pressing the desired Trunk Hundreds Select 
    button.  This has no effect on the activation or deactivation of the feature.  For 
    example, if the attendant presses the C
    ONT ACT b utton and then has to answer 
    another call, the desired Trunk Hundreds Select button can b e pressed after 
    answering the call. Attendant Control of Trunk Group Access is then activated for 
    the associated trunk group.
    Considerations
    By activating Attendant Control of Trunk Group Access, the attendant obtains 
    control of access to specific trunk groups.  This allows the attendant to monitor 
    the use of these trunk groups.  By watching the lamps associated with the trunk 
    groups, the attendant can determine if the number of busy trunks in a specific 
    trunk g roup has reached a preset warning level and if all trunks in a specific trunk 
    group are busy.  The attendant can then handle other calls to these trunk groups 
    accordingly.
    This feature can be activated for any trunk group assigned to a Trunk Group 
    Select button with an associated control lamp. Each attendant in the system can 
    control access to six (basic console) or 12 (enhanced console) different trunk 
    groups.
    If Attendant Control of Trunk Group Access is activated, and no attendant is 
    assigned, or the attendant is later removed, calls to a controlled trunk group 
    route to the attendant queue.
    Interactions
    The following features interact with the Attendant Control of Trunk Group 
    Access feature.
    nAttendant Direct Trunk Group Selection
    This feature must be assigned with Attendant Control of Trunk Group 
    Access feature. 
    						
    							Attendant Control of Trunk Group Access
    Issue  3   March 1996
    3-105
    nAttendant Display
    When a call redirects to the console because Attendant Control of Trunk 
    Group Access is activated, the alphanumeric disp lay identifies the calling 
    party and shows that the call has attempted to access a controlled trunk 
    group.
    nAutomatic Route Selection and Automatic Alternate Routing (ARS/AAR)
    Activating Attendant Control of Trunk Group Access removes the 
    controlled trunk group(s) from the Automatic Route Selection and 
    Automatic Alternate Routing patterns.  Deactivating the feature reinserts 
    the group(s) into the patterns. Automatic Route Selection calls are not 
    routed to the attendant.
    nTrunk Group Busy/Warning Indicators to Attendant
    This feature keeps the attendant informed of trunk group status. This 
    status can be used to determine when to activate control.
    nUniform Dial Plan (UDP)
    Activating Attendant Control of Trunk Group Access removes the 
    controlled trunk group(s) from preferences. Deactivating the feature 
    enables the (UDP) to access the trunk groups.
    nAuthorization Codes
    When a trunk group has an incoming destination set to the Attendant, 
    authorization codes are 
    not collected.
    Administration
    Attendant Control of Trunk Group Access is assigned on a per-attendant console 
    basis by the System Manager.  The following items require administration:
    nAttendant Console
    — Trunk groups which are to be controlled
    — The Control A ctivate button is 
    ACT-TR-GRP and the Control 
    Deactivate button is 
    DEACT-TR-GRP.
    nControlled Trunk  Groups
    — Busy Threshold
    Hardware and Software Requirements
    No a d ditional hardware or software is required.

    Attendant Direct Extension Selection
    With Busy Lamp Field
    Feature Availability
    This feature is available with all Generic 3 releases.
    Description
    Allows the attendant to trac k extension status (idle or busy) and to place or 
    extend calls to extension numb ers assigned to the system without having to dial 
    the extension numb er. The attendant can use this feature in two ways:
    nUsing standard Direct Extension Selection (DXS) access. If you use an 
    attendant c onsole that has one or more Hundreds Select buttons, you can 
    press a Hundreds Select button and a DXS button to access a station.
    nUsing enhanced DXS access. The functionality is useful when:
    — You use an attendant console that does not use Hundreds Select 
    buttons.
    — You use an attendant console with Hundreds Select buttons, but 
    you have one or more hundreds groups not administered by a 
    Hundreds Select button. In this case, you can use a Group Select 
    button and dial the first two or three d igits of the station and then 
    use the DXS button to access the station. Please see the 
    Enhanced DXS Tracking subsection below.
    In both cases (using a Hundreds Select b utton or the Group Select button), when 
    the system is tracking a group of extensions, the attendant can place or extend 
    subsequent calls to extensions in that group simply by pressing the DXS button, 
    without having to reselect the group. Both of these c a pabilities eliminate the need 
    to dial extensions.
    The extension numbers may be voice terminal extensions, hunt group 
    extensions, off-switch extensions (such as UDP extensions), or nonvoice terminal 
    extensions.
    Whichever method you use to access and track DXS extensions, you can view 
    the group of extensions c urrently being trac ked b y using a Group Display feature 
    button. This button, on the console disp lay, indicates the range of extensions 
    being tracked by the selector console.
