    Administered Connections failure: Auto
    Restoration and Fast Retry
    When an active AC drops prematurely, you must invoke either auto restoration or 
    fast retry to determine whether auto restoration is attempted for an active AC.
    If you option AC for auto restoration and the connection was routed over SDDN 
    trunks, auto restoration is attempted. During restoration, connections are 
    maintained between the switch and both endpoints. In addition to allowing the 
    active session to be maintained, AC also provides a high level of security by 
    prohibiting other connections from intervening in active sessions. Auto 
    restoration generally completes before the 60-second endpoint holdover interval. 
    If auto restoration is successful, the call might be maintained (no guarantee). The 
    restoration is transparent to the user with the exception of a temporary disruption 
    of service while restoration is in progress. A successful restoration is reflected by 
    the restored state on the status Administered Connection screen. Although the 
    restoration was successful, the data session may not have been preserved.
    If auto restoration is not active or if the AC is not routed over SDDN trunks, the 
    switch immediately attempts to reestablish the connection (fast retry). The switch 
    also attempts a retry if the originating endpoint initiated the drop. With fast retry, 
    connections are not maintained on both ends. Fast retry is not attempted for an AC 
    that was last established via fast retry, unless the AC is active for at least two 
    minutes.
    If auto restoration or fast retry fails to restore or reestablish the connection, the 
    call drops and the AC goes into retry mode. Retry attempts continue, at the 
    administered retry interval, as long as the AC is due to be active.
    Interactions
    nAbbreviated Dialing
    Use Abbreviated Dialing entries in the Destination field on the 
    Administered Connection screen. Entries must comply with restrictions.
    nBusy Verification of Stations and Trunks
    This feature does not apply to access endpoints because they are used only 
    for data.
    nCall Detail Recording
    For an AC that uses a trunk when CDR is active, the origination extension 
    is the originator of the call.
    CDR is not available for access endpoints.

    nClass of Restriction
    Reserve a COR for AC endpoints and SDDN trunks. This restricts 
    endpoints that are not involved in AC from connecting to SDDN trunks or 
    endpoints involved in AC.
    nClass of Service/Call Forwarding
    Assign to an AC endpoint a COS that blocks Call Forwarding activation at 
    the endpoint.
    nData Call Setup
    Do not assign a default dialing destination to a data module when it is used 
    in an AC.
    nData Hotline
    Do not assign a hotline destination to a data module that is used in an AC.
    nDigital Multiplexed Interface (DMI)
    Use DMI endpoints as the destination in an AC. DMI endpoints do not 
    have associated extensions, so do not use them as the originator in an AC.
    nFacility Test Calls
    The feature does not apply to access endpoints because an access endpoint 
    acts as an endpoint rather than as a trunk.
    nHunting
    Do not use a hunt-group extension as the origination extension of an AC.
    nModem Pooling
    If you require a modem in an AC, one is inserted automatically. If no 
    modem is available, the connection drops.
    nNon-Facility Associated Signaling (NFAS) and D-Channel Backup
    Auto restoration for an AC that initially is routed over an NFAS facility 
    may fail if the only backup route is over the facility on which the backup 
    D-channel is administered. The backup D-channel may not come into 
    service in time to handle the restoration attempt.
    nSet Time Command
    When you change the system time via the set time
     command, all scheduled 
    AC are examined. If the time change causes an active AC to be outside its 
    scheduled period, the AC drops. If the time change causes an inactive AC 
    to be within its scheduled period, the switch attempts to establish the AC.
    If any AC (scheduled or continuous) is in retry mode and the system time 
    changes, the switch attempts to establish the AC.

    nSystem Measurements
    Access endpoints are not measured. All other trunks in an AC are measured 
    as usual.
    nTerminal Dialing
    Turn off terminal dialing for data modules involved in an AC. This 
    prevents display of call-processing messages (INCOMING CALL,...) on 
    the terminal.
    nTrunk Groups
    To invoke auto restoration, route an AC over SDDN trunks. Because a 
    successful restoration depends on a SDDN path, keep some SDDN trunks 
    idle.
    Administrable Language Displays
    You can display messages in English, French, Italian, Spanish, or a user-defined 
    language on attendant consoles and phones that have 40-character displays.
    Detailed description
    You can select a language for messages that appear on phones and attendant 
    consoles that have 40-character displays. You can choose one of five languages: 
    English, French, Italian, Spanish, or “user-defined.” The meanings of the 
    messages do not change, only the language.
    If your company uses 32-character display phones, you cannot choose a display 
    language. These phones, including the hybrid MERLIN 7315H and 7317H 
    phones, default to English.

    Alternate facility restriction levels
    Alternate Facility Restriction Levels (AFRL) allows a second set of facility 
    restriction levels within a route pattern or for lines or trunks. Attendants and 
    system administrators can activate the alternate FRLs and change users’ access to 
    lines and trunks. For example, a company can use AFRL to disable long-distance 
    calling at night to prevent unauthorized staff from making long-distance calls.
    AFRL alters the route patterns for originating phones, originating trunks, and 
    dialed authorization codes. If AFRL is active, Travelling Class Mark (TCM) is 
    also set to a new FRL value and the TCM information recorded in the billing data 
    (CDR) is the AFRL value, not the original TCM.
    !CAUTION:
    AFRL impacts Automatic Alternate Routing (AAR) and Automatic Route 
    Selection (ARS) call routing because it may change routing preferences. 
    Using AFRL on tandem and tie-trunk applications affects entire networks. 
    Calls that are part of a cross-country private network and may have to be 
    routed further may be blocked.

    Detailed description
    You can administer an 
    ALT-FRL button to any attendant console or any station to 
    activate and deactivate the AFRL. Pressing the 
    ALT-FRL button may affect the 
    status of other buttons.
    When AFRL is active, the user may notice a change in calling privileges. 
    Consider notifying users of the changes, and prepare your telecommunications 
    department to handle inquiries.
    Authorization codes
    Authorization codes prevent unauthorized access to various facilities. When a 
    user dials an authorization code, your system checks the code. If it is not valid, the 
    call is intercepted. If the code is valid, the system determines an associated COR 
    and FRL. If AFRL is activated, the AFRL level is used.
    For example, a user whose FRL is 1 attempts a long-distance call. AFRL is active 
    and maps to AFRL 3. The desired trunk has an FRL of 7, and the call is blocked. 
    In the example below, an Authorization Code set to1234567 has a COR of 3 with 
    an FRL 5, which is still not high enough to access the desired trunk. However, 
    AFRL is active and FRL 5 maps to FRL 7. The call is allowed.

    1152 Answer detection 
    20
    Answer detection
    For proper call detail recording and accurate billing, you need to know when your 
    outgoing calls are answered. Answer detection means the method a switch uses to 
    determine whether an outgoing call has been answered.
    Brief description
    DEFINITY ECS provides 3 ways to determine whether the called party has 
    answered a call.
    Call classification
    A call-classifier circuit pack detects tones and voice-frequency signals on the line 
    to determine whether a call has been answered. This method is fairly accurate: 
    calls that are answered normally are usually classified correctly. But there are 
    exceptions:
    nMiscellaneous tones, such as confirmation tones, may be classified as 
    answers.
    nLoud background noise may activate answer detection, causing a call to be 
    classified as answered even if the call is not connected.
    nSome calls that are answered may be incorrectly classified as fast busy 
    signals.
    nCall classifier circuit packs also don’t recognize Special Information Tones 
    (SIT) as answers.
    Of course, the system generates a call record for any call that is classified as 
    answered whether the classification is correct or not. If Call Classification 
    incorrectly classifies a call as answered, and then the call is subsequently 
    answered, the call duration reported by CDR includes the both time between the 
    incorrect classification and the actual answer and the remaining duration of the 
    call.
    If you want to use call classification, on the System Parameter Customer-Options 
    screen verify the Answer Supervision by Call Classifier field is 
    y. If not, contact 
    your Lucent representative. You also must have a call classifier circuit pack of the 
    correct type. To find out what circuit packs you need, refer to DEFINITY ECS 
    System Description.

    Features and technical reference 
    1153 Answer detection 
    20
    Network answer supervision
    The central office sends a signal to the originating switch to indicate that the far 
    end has answered. If a call traveled over a private network before reaching the 
    central office, the signal is transmitted back over the private network to the 
    originating switch. This method is extremely accurate, but it is not available over 
    most loop-start trunks (for example, CO, FX and WATS trunks in the US).
    Network answer supervision does not override answer supervision by timeout.
    Answer supervision by timeout
    You set a timer for each trunk group, using the Answer Supervision Timeout field 
    on the Trunk Group screen. Or you set a circuit pack timer for the ports on that 
    circuit pack, using the Outgoing End of Dial (sec) field on the Trunk Group 
    screen. If the caller is off-hook when the timer expires, the system assumes that 
    the outgoing 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. 
    If network answer supervision is received, it overrides answer supervision by 
    timeout.
    Interactions
    nCall Detail Recording
    Answer Detection provides more accurate call records where tone 
    detection is possible and Network Answer Supervision is not received.
    nCall Prompting
    Call classification competes with Call Prompting for ports on the call 
    classifier circuit pack.
    nCallVisor ASAI
    Call classification 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.

    n‘‘Visually Impaired Attendant Service’’ on page 1162
    Each feature indicates how to administer the Attendant Console screen, Console 
    Parameters screen, and other system-wide screens to enable the feature.
    Attendant Call Waiting
    Attendant Call Waiting allows an attendant-originated or attendant-extended call 
    to a busy single-line telephone to wait at the called telephone so that the attendant 
    can handle other calls.
    If you want the attendant to be able to send calls to busy single-line phones, set the 
    Att. Call Waiting Indication field to Y on the Station
     screen for each single-line 
    phone. 
    When the single-line phone receives a waiting call, the phone user hears a 
    call-waiting signal. You can administer the number of bursts (1, 2, or 3) in the 
    call-waiting signal by changing the Attendant Originated Calls field on the 
    Feature-Related System Parameters
     screen.
    If the attendant activates Attendant Call Waiting, and the Timed Reminder on 
    Hold interval or the Return Call Timeout interval expires without the call being 
    answered, the call returns to the console. You can modify these intervals on the 
    Console Parameters
     screen.

    Interactions
    nAutomatic Callback
    Activating Automatic Callback at the called telephone denies Attendant 
    Call Waiting.
    nCall Coverage
    Attendant Call Waiting calls redirect to coverage if the called phone has 
    Data Privacy or Data Restriction activated. If one of these conditions 
    exists, and you assign call coverage to a telephone, and the user activates 
    Send All Calls or coverage criteria is met, the call redirects to coverage.
    — The Coverage Don’t Answer interval specifies how long a call 
    remains directed to the called telephone before redirecting to 
    coverage. Attendant Call Waiting if applicable on the call, is active 
    for the duration of the Don’t Answer interval only. At the end 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 console if a coverage point does not answer the call 
    before the Return Call Timeout.
    — If the Station Hunting field is assigned and the called telephone is 
    busy, the call redirects to the Hunt To Station Assignment.
    nData Privacy, Data Restriction
    Activating Data Privacy or Data Restriction at the called telephone denies 
    Attendant Call Waiting.
    nDDC and UCD
    Calls to a DDC or UCD group do not wait. However, they can enter the 
    group queue, if provided.
    nLoudspeaker Paging Access
    Activating Loudspeaker Paging Access at the called telephone denies 
    Attendant Call Waiting.
    nMusic-on-Hold Access
    The calling party hears music if the call is a trunk-transferred call 
    administered to receive Music-on-Hold. Otherwise, the calling party hears 
    ringing.
    nRecorded Telephone Dictation Access
    Activating Recorded Telephone Dictation Access at the called telephone 
    denies Attendant Call Waiting.

    Attendant Control of Trunk Group Access
    Attendant Control of Trunk Group Access allows the attendant to control trunk 
    groups, and prevents telephone users from directly accessing a controlled trunk 
    group. The attendant gains direct access to an outgoing trunk group by pressing 
    the button assigned to that trunk group.
    Each attendant console has 12 designated Trunk Hundreds Select buttons that can 
    be administered for Attendant Control of Trunk Group Access. You can also 
    administer each console with up to 12 feature buttons for Trunk Hundreds Select 
    buttons, which gives you up to a total of 24 buttons.
    Each Trunk Hundreds Select button has busy lamps that light when all the 
    members of the associated trunk group are busy. If you administer one of the 
    2-lamp feature buttons on a basic console as a Trunk Hundreds Select button, use 
    the bottom lamp as the busy lamp. These buttons have 2 additional lamps for 
    Attendant Control of Trunk Group Access. The 2 lamps are:
    nWarn (warning) lamp
    Lights when the administered number of trunks are busy in the associated 
    trunk group. You administer the Busy Threshold field on the associated 
    Trunk Group
     screen to determine when to light this warning lamp.
    nCont (control) lamp
    Lights when the attendant activates Attendant Control of Trunk Group 
    Access for the associated trunk group. Assign act-tr-grp and deact-tr-g 
    buttons on the Attendant Console
     screen to allow the attendant to activate 
    and deactivate control of the trunk group access.
    Interactions
    nAuthorization Codes
    Authorization codes do not collect when a trunk group has an incoming 
    destination set to the attendant.
    nAutomatic Route Selection and Automatic Alternate Routing (ARS/AAR)
    Activating Attendant Control of Trunk Group Access removes the 
    controlled trunk groups from the ARS and AAR patterns. Deactivating the 
    feature reinserts the groups into the patterns. ARS calls do not route to the 
    attendant.
    nQSIG
    QSIG trunks do not support Attendant Control of Trunk Group Access.
    nUniform Dial Plan 
    Activating Attendant Control of Trunk Group Access removes the 
    controlled trunk groups from preferences. Deactivating the feature enables 
    the UDP to access the trunk groups.
