    using Norstar call handling features 
    such as Call Park or Call Pickup 
    Directed.
    Internal number:  A number (also 
    referred to as a Directory Number or 
    DN) that identifies a Norstar telephone 
    or device.
    Internal user:  Someone using a 
    Norstar telephone within a Norstar 
    system.
    ISDN: See integrated services digital 
    network.
    ISDN DN:  A directory number (DN) 
    used by ISDN terminal equipment 
    connected to the ICS. The system uses  a 
    maximum of seven ISDN DNs.
    K
    key service unit (KSU):  See ICS 
    (integrated communication system).
    L
    Last Number Redial: ²Þ
    A feature that allows you to redial the 
    last external number you dialed.
    Least cost routing:  See Routing 
    service.
    Line:  The complete path of a voice or 
    data connection between one telephone 
    (or other device) and another. 
    Lines:  A programming section that 
    allows you to assign settings to each 
    trunk and external line. Lines 
    programming can be done by an 
    installer or  a system coordinator plus.  A 
    system coordinator can program the 
    name of a line.
    Line restriction:  See Restriction 
    filter.Line number:  A number that 
    identifies an external line. The total 
    number of lines depends on how many 
    Trunk Cartridges are installed.
    Line Pool:  
    ²ßÝ
    A group of lines used for making 
    external calls. Line pools provide an 
    efficient way of giving a telephone 
    access to external lines without taking 
    up many line buttons. A line is assigned 
    to be part of a line pool under Trunk/
    Line data in Lines programming.
    Line Redirection: 
    ²¡Ý
    A feature that allows you to redirect all 
    calls on an incoming line to a 
    destination outside the Norstar system. 
    Once a line is redirected it cannot be 
    answered within the Norstar system. 
    The system may be set  up to give a brief 
    ring when a call comes in on a redirected 
    line, under Capabilities in Terminals 
    and Sets programming. 
    This feature differs from Call Forward 
    in two ways. It redirects only external 
    calls (not internal calls) and it redirects 
    calls to destinations outside the system. 
    Call forward redirects calls only to 
    destinations inside the Norstar system. 
    See Call Forward.
    Link: 
    ²àÚ
    If your Norstar system is connected to a 
    Private Branch Exchange (PBX), you 
    can use a Link signal to access special 
    features. The Link signal can also be 
    included as part of a longer stored 
    sequence on an External Autodial 
    button or in a Speed Dial code. The Link 
    symbol (
    ¤) uses two of the 24 spaces 
    in a dialing sequence.
    Long Tones: 
    ²¡â¡
    A feature that allows you to control the 
    length of a tone so that you can signal 
    devices such as fax or answering 
    machines which require tones longer 
    than the standard 120 milliseconds.
