    Features and technical reference 
    1447 Multiappearance Preselection and Preference 
    20
    nIdle Appearance Preference
    When a user lifts the handset to place a call, the system automatically 
    connects them to an idle appearance even if an incoming call is ringing at 
    another appearance. The in-use (red) lamp tracks an idle appearance when 
    the user lifts the handset.
    nLast Appearance Preference
    When a user lifts the handset, they connect to the call appearance or 
    bridged appearance last used for a call, unless an audibly ringing call on a 
    different appearance caused the line selection to move. If the line selection 
    moves, a call may be originated, answered, or unheld, depending on the 
    state of that appearance.
    nPreselection
    Before lifting the handset to place or answer a call, the user can press a call 
    appearance button or a feature button to select an appearance when the 
    in-use lamp is dark. Preselection reenters a held call or activates a feature 
    or the speakerphone if the telephone is so equipped.
    Preselection overrides both Preference options. If the user does not lift the 
    handset within 5 seconds after using Preselection, the selected appearance 
    returns to idle.
    You can assign a preselection feature button. For example, if a user presses 
    an Abbreviated Dialing button, a call appearance is automatically selected. 
    If the user lifts the handset within 5 seconds, the system automatically 
    places the call.
    Preference dictates whether a user connects to the ringing call appearance 
    or to an idle call appearance. If there is no call, users automatically connect 
    to an idle call appearance when they lift the handset, regardless of which 
    Preference option is assigned.
    Considerations
    nMultiappearance telephones can have from 2 to 10 call appearances. One 
    of these call appearances is reserved for placing calls or for receiving a 
    Priority Calling call. If a telephone has 2 call appearances and one of them 
    is active, a nonpriority call cannot access the other call appearance, even if 
    the call appearance is idle. The default number of call appearances is 3.
    nThe reserved call appearance is not a fixed-position button; it is just the 
    last-idle call appearance. For example, if a telephone has 10 call 
    appearances, any 9 can be in use, but the tenth (last) is reserved.

    nAutomatic Incoming Call Display
    Incoming calls are not displayed if Idle Appearance Preference is activated.
    nCall Coverage
    If you administer Cover All Calls as the redirection criterion for a 
    telephone, administer Idle Appearance Preference for the telephone. The 
    called party can then lift the handset without accidentally connecting to a 
    call that should be screened.
    nIntegrated Services Digital Network — Basic Rate Interface
    When an ISDN-BRI telephone (with Select Last Used Appearance 
    enabled) transfers a call while off-hook by using the handset, the user hears 
    dial tone on the last-used call appearance. Users of other telephone types 
    hear silence in this case.

    Multifrequency Signaling
    Multifrequency (MF) signaling is a form of address signaling used between 
    switches and the central office (CO). It is similar to dual-tone multifrequency 
    (DTMF) signaling in that tones convey the dialed number.
    With MF signaling, the signal is typically a combination of two frequencies from 
    a group of 5 or 6 frequencies (2/5 or 2/6). The origination switch and destination 
    switch exchange tones that have specific meanings according to the MF protocol.
    Detailed description
    DEFINITY ECS supports two frequency groups:
    nR2-multifrequency compelled signaling (R2-MFC) frequency
    nR1 frequency (for Spain and Russia)

    1449 Multifrequency Signaling 
    20
    R2-MFC is a version of MFC recommended by the International 
    Telecommunication Union (ITU). It provides signaling between a CO and a 
    switch over analog or digital CO, Direct Inward Dialing (DID), or Direct Inward 
    and Outward Dialing (DIOD) trunks. It also provides signaling between 2 
    DEFINITY switches.
    DEFINITY ECS provides MF signaling that complies with ITU regulations and 
    national regulations for specific countries. It provides these types of MF 
    signaling: Multifrequency Espana (MFE), MF Shuttle, and multifrequency 
    compelled (R2-MFC). These protocols signal the called number, the calling 
    party’s number (automatic number identification (ANI)), and information about 
    the type of call or type of caller (category).
    DEFINITY ECS allows prefix digits for ANI sent on outgoing calls to be defined 
    per PBX or per the originator’s class of restriction.
    If a call is a tandem call and the incoming and outgoing trunk use different 
    protocols, the switch makes no attempt to convert between the various protocol’s 
    meanings for category. Instead,
    nthe PBX uses the incoming trunk’s Class of Restriction (COR) assigned 
    category if the outgoing trunk is Russian or R2-MFC, and
    nthe PBX uses ARS call types if the outgoing trunk is MFE.
    DEFINITY ECS provides the incoming ANI to all features on the switch that need 
    to identify the calling party.
    MFE
    MFE, for Country code 11 (Spain), uses R1 frequency and compelled signaling. It 
    is available on CO and DID trunk groups. There are four kinds of MFE signaling:
    nPublic 2/5
    nPublic 2/6
    nIbercom 2/5
    nIbercom 2/6

    MF Shuttle
    MF shuttle signaling, for country code 15 (Russia), uses R1 frequency and 
    noncompelled signaling. With MF shuttle signaling, it is possible to change to 
    decadic rotary pulse in the middle of address signal exchange. MF shuttle 
    signaling is available on CO, DID, and DIOD trunk groups.
    Also, automatic number identification (ANI) transmission, for Country code 15, 
    uses a gapless R1 MF signal and is completed within 800ms. This is available on 
    an outgoing CO trunk group.
    R2-MFC
    R2-MFC permits each country to define the meanings of the R2 frequency 
    combinations. Specific frequency combinations for different countries are 
    described in the DEFINITY ECS Application Notes for Type Approval.
    R2-MFC Considerations
    nBoth non-group II signaling and group II signaling are supported on 
    incoming MF signaling calls. The group II signaling protocol has an extra 
    signal that provides caller-category information. Only group II signaling is 
    supported on outgoing MF signaling calls.
    nMF signaling also can be used in tandem trunk groups. After address 
    signals are collected from an incoming group II MF signaling call, the call 
    can route to a group II MF signaling trunk.
    nBoth incoming and outgoing MF signaling calls support ANI. The terminal 
    displays ANI information and the Call Detail Recording (CDR) record 
    records it.
    nWhen DEFINITY ECS uses an open numbering plan, the end-of-dial 
    signal must be defined in the incoming Group I signal administration. After 
    sending all address digits, the CO sends the end-of-dial signal to 
    DEFINITY ECS. 
    nIf DEFINITY ECS makes an outgoing call to the CO that uses an open 
    numbering plan, the CO should send the signal A.1 to DEFINITY ECS 
    after sending the last address digit to the CO. Then, the CO should timeout 
    and send a pulsed signal A.3 to DEFINITY ECS requesting the Group II 
    signal.

    Guidelines for administering MF signaling
    To administer MF signaling, first you identify the origination switch and the 
    destination switch. (The switch making the call is the origination switch; the 
    switch answering the call is the destination switch.) 
    nThe origination switch creates forward signals, classified as group I and 
    group II signals. 
    nThe destination switch creates backward signals, classified as group A and 
    group B signals. 
    Group I and group A signals comprise the basic signaling for the dialed number. 
    More elaborate signaling requires Group II and group B signals. Signal meanings 
    and timer values can be administered.
    The sequence below shows a typical interaction between the origination (forward 
    group I and group II signals) and destination switch (backward group A and group 
    B signals).

    Second, you assign the correlation between signal codes and their meanings.
    1. Assign a code to every message. The code consists of a group category, like 
    group II or A, and a number.
    nFor example, you might assign code A.1 to the message 
    “next-digit.” 
    2. Assign a signal to each identifying code. 
    nIn every country, the frequencies (levels may differ by country) 
    assigned to the identifying codes are the same. However, the 
    messages assigned to the identifying codes may be different. 
    For example, in Switzerland the B.6 code and its associated signal 
    convey the free message, while in Thailand, free is conveyed by the 
    B.1 code and its associated signal. But in both Switzerland and 
    Thailand, the frequency associated with the B.1 code is the same.
    As another example, you might assign the signal “busy” to the B.1 
    code.
    To receive Russian incoming ANI:
    nOn the DID or DIOD trunk group screen, set the Country field to 15 and 
    the Protocol Type field to 
    inloc.
    nOn AAR and ARS Digit Analysis Table screen, set the ANI Rq field to y or 
    on AAR and ARS Digit Conversion Table screen, set the ANI Req field 
    to
    y.
    Interactions
    nASAI
    ANI collected from incoming R2-MFC signaling can be used with ASAI.
    nAbbreviated Dialing
    Although calls dialed automatically from an abbreviated dialing privileged 
    list complete without class of restriction (COR) checking, ANI prefix and 
    ANI truncation still apply.
    nAttendant Console
    If the attendant assists or extends a call for a station via Straightforward 
    Outward Completion and Through Dialing, and if the attendant has not yet 
    released the call when the request for ANI comes in from the far end, the 
    attendant’s COR is used to select the ANI for the call. If the attendant has 
    already released the call when the request for ANI comes in from the far 
    end, the attendant’s COR is used to select the ANI for the call.

    nAuthorization Codes
    The COR of the authorization code as administered on the 
    authorization-code form is not used for ANI prefix determination, even if 
    the originating endpoint enters an authorization code before call processing 
    for an outgoing call seizes an outgoing trunk. If the originating endpoint is 
    an extension, the extension’s ANI is used. If the originating endpoint is an 
    incoming trunk, the ANI for PBX is used.
    nBridging
    The ANI of a telephone’s primary extension also applies to calls originated 
    from a bridged call appearance of that extension on another terminal. ANI 
    prefix and ANI truncation will still apply to the primary extension number 
    of bridged call appearances.
    nCall Detail Recording
    CDR records ANI collected from incoming MF signaling.
    For India MFC, on incoming calls, ANI digits may be appended with 
    zeroes if the actual ANI digits are less than the administered ANI-length; in 
    those cases, the zero-digits appear on CDR.
    nCall Redirection
    A call is redirected if any of the following are active: Call Forwarding, Call 
    Coverage, Send All Calls, or Night Service.
    nCall Vectoring
    Call Vectoring can now use ANI collected from incoming MFC signaling.
    The ANI of a call vector is not used when a call vectoring route-to 
    command routes a call over an outgoing trunk. Instead, the ANI of the 
    originating party is sent.
    nDID No Answer Timer
    DID No Answer Timer is applied to MF signaling DID calls.
    nDistributed Communications System (DCS)
    In a DCS arrangement, the ANI sent to the CO is determined by the ANI 
    for PBX on PBX_B, but the category sent to the CO is determined by the 
    Category for MF ANI field on the Class of Restriction form for the 
    incoming DCS trunk or by the type of call.
    nExpert Agent Select (EAS)
    For ANI, the EAS agent’s login extension number and COR overrides the 
    extension number and COR of the physical terminal where the agent is 
    logged in. ANI prefix and ANI truncation apply to logged in EAS agents.

    nHunt Groups and Automatic Call Distribution (ACD) Splits
    For ANI, a physical terminal’s extension number and COR overrides the 
    extension number and COR of the hunt group or ACD split that the 
    terminal is a member of or logged into. ANI prefix and ANI truncation 
    apply to terminals that are members of hunt groups or logged into ACD 
    splits.
    nIntercept treatment
    For DID MF signaling calls that are denied, you can administer whether the 
    corresponding B.x signal or intercept tone should be sent to the CO. The 
    default is to send the administered DID/TIE/ISDN Intercept Treatment. If 
    the option to send the B.x signal is set, then:
    — For Group II calls, the B.x signal for the intercept is sent to the CO.
    — For non-Group II calls, if the CO dials an invalid number, the trunk 
    is locked (regardless of this option). If the CO dials a number that is 
    valid but not assigned, intercept tone is sent to the CO.
    nMultimedia Call Handling (MMCH)
    For call origination, multimedia complexes use the COR assigned to their 
    telephones. ANI prefix and ANI truncation will apply to the telephones 
    assigned to multimedia complexes.
    nOff-Net Call Coverage or Call Forwarding
    If the originating endpoint is an extension, the extension’s ANI is used. If 
    the originating endpoint is an incoming trunk that can supply ANI, the ANI 
    received from the incoming trunk is used. If the originating endpoint is 
    neither of the above, the ANI for PBX is used.
    nPersonal Station Access (PSA)
    For ANI, the PSA extension number and COR overrides the extension 
    number and COR of the physical terminal where the PSA extension 
    number is associated. ANI prefix and ANI truncation will apply to 
    associated PSA extension numbers.
    nRemote Access
    The COR of a remote access barrier code is not used for ANI prefix 
    determination when the originating end point dials a remote access 
    extension and then places a call. If the originating endpoint is an extension, 
    the extension’s ANI is used. If the originating endpoint is an incoming 
    trunk, the ANI for PBX is used.

    nStation Set Displays
    When no ANI is possible, if station sets are equipped with display option, 
    they do not display the ANI digits. Instead, the trunk group name displays. 
    When ANI is possible, ANI displays on the station set.
    For India Only. If ANI digits are padded with “zero,” then zeroes also are 
    displayed along with ANI digits.
    nTandem / Offnet Calls
    If ANI digits are received on incoming MFC calls, the ANI digits are sent 
    to outgoing tandem/off-net calls.
    For Russia Only. The ANI is requested on incoming trunks only when all 
    the address digits have been collected. When the incoming trunk on a 
    tandem call is a Russian incoming local trunk administered to collect ANI, 
    the PBX collects all ANI digits before seizing the outgoing tandem trunk. 
    This happens even if ARS is administered with a “min” value low enough 
    that it would be possible to determine an outgoing route through digit 
    analysis.
    For India Only. On an outgoing tandem-call, the default operation is to 
    send the ANI-Not-Available forward signal if ANI is not available from the 
    incoming trunk. However, in order to support this operation, leave the ANI 
    for PBX field blank, and define the ANI-Not-Available signal.

    DEFINITY ECS provides the following Night Service features:
    nHunt Group Night Service
    nNight Console Service
    nNight Station Service
    nTrunk Answer from Any Station
    nTrunk Group Night Service
    Hunt Group Night Service
    Hunt Group Night Service allows an attendant or a split supervisor to assign a 
    hunt group or split to Night Service mode. All calls for the hunt group then are 
    redirected to the hunt group’s designated Night Service extension (NSE). When a 
    user activates Hunt Group Night Service, the associated button lamp lights.
    Night Console Service
    Night Console Service directs all calls for primary and daytime attendant consoles 
    to a night console. When a user activates Night Console Service, the Night 
    Service button for each attendant lights and all attendant-seeking calls (and calls 
    waiting) in the queue are directed to the night console.
    To activate and deactivate this feature, the attendant typically presses the Night 
    button on the principal attendant console or designated console.
    Night Station Service
    Night Station Service directs incoming calls for the attendant to designated 
    extensions. Attendants can activate Night Station Service by pressing the Night 
    button on the principle console if there is not an active night console. If the night 
    station is busy, calls (including emergency attendant calls) receive busy tone. 
    They do not queue for the attendant.
    When Night Station Service is active, incoming calls to the attendant route as 
    follows:
    nDID Listed Directory Number (LDN) calls route to a designated DID-LDN 
    night extension.
    nInternal calls route to the DID-LDN night extension (unless you administer 
    the system so only DID-LDN calls can route to the LDN night extension).
