    Features and technical reference 
    1307 Class of Restriction 
    20
    Interactions
    nAAR/ARS
    Originating FRLs are assigned via a COR. Termination and Miscellaneous 
    Restrictions do not apply to ARS/AAR calls.
    nAAR/ARS Partitioning
    Partition Group Numbers are assigned via a COR.
    nBridged Call Appearance
    The COR assigned to a telephone’s primary extension also applies to calls 
    originated from a bridged call appearance of that extension on another 
    terminal.
    nCall Coverage
    Users who normally are restricted from calls can still receive calls directed 
    to them via Call Coverage. When a call goes to coverage, the called party’s 
    (not the covering party’s) restrictions are used.
    nCall Forwarding All Calls
    If a call is restricted between the forwarding and forwarded-to extensions, 
    Call Forwarding is denied. Restrictions are always checked when Call 
    Forwarding is activated, but not when a call is forwarded.
    nCall Vectoring
    When a call is directed to a VDN extension, the COR of the caller and the 
    VDN are compared to determine if the caller can access the associated call 
    vector.
    nClass of Service
    In some cases, the COR can be overridden by the COS. See the Trk-to-Trk 
    Restriction Override field documented with the ‘‘
    Class of Service’’ on page 
    532.
    nControlled Restriction
    Restrictions assigned via Controlled Restriction override COR restriction.
    nEmergency Access to Attendant
    Emergency Access to Attendant calls are not restricted by COR.
    Interactions for called-party and calling-party restrictions
    nNight Service
    Night Service and Night Station — Trunk Answer From Any Station 
    override Inward, Manual Terminating Line, and Public Restrictions.

    Features and technical reference 
    1308 Class of Restriction 
    20
    nTie-Trunk Access
    Incoming dial-repeating tie-trunk calls can be completed directly to an 
    inward-restricted or public-restricted extension but cannot be extended by 
    an attendant to an inward-restricted telephone.
    nTransfer
    Incoming trunk calls cannot be transferred to an inward-restricted 
    extension when a 3-way COR check is made.
    Incoming trunk calls can be transferred from an unrestricted extension to 
    an inward-restricted or public-restricted extension if the 3-way COR check 
    on Conference is overridden.
    Interactions for fully restricted service restrictions
    nCentralized Attendant Service
    Since COR information is not passed over Release Link Trunks (RLT), 
    fully restricted service allows all CAS calls. Therefore, CAS allows a 
    public network call to complete to a fully-restricted station.
    nDistributed Communications System
    Fully Restricted Service allows all DCS calls because COR information is 
    not transparent for DCS. DCS can allow a public network call to be 
    completed to a Fully Restricted station.
    nPower Failure Transfer
    All authorization features are bypassed when the switch is in Emergency 
    Transfer Mode. 
    nHunt Group
    The COR assigned to the Hunt Group is checked on calls redirected by the 
    DDC or UCD of the hunt group. Extensions in the hunt group that have 
    Fully Restricted Service can receive calls from the public network (via the 
    hunt group) if the COR of the Hunt Group does not have Fully Restricted 
    Service.
    nPersonal Central Office Line
    Do not assign fully restricted service to users who have a personal CO line. 
    If you do, you will be paying for a CO line that no one can use! 
    nRemote Access
    If a barrier code is entered during connection to remote access, the code’s 
    associated COR is used for authorization checks. If remote access does not 
    require a barrier code, then the default barrier code’s COR is used. Remote 
    Access can require an authorization code instead of or in addition to the 
    barrier code. If an authorization code is required, the authorization code’s 
    associated COR overrides the barrier code’s COR.

    Features and technical reference 
    1309 Conference 
    20
    Do not assign fully restricted service to a station with the following features or 
    conditions:
    nAbbreviated Dialing
    nBridged Call Appearance
    nAttendant stations
    nNight Service stations
    nStations that are Call Coverage or Send All Calls points
    nStations that are Call Forward destinations
    nStations that are Call Pickup points
    Interactions for miscellaneous terminal and trunk restrictions
    nAAR/ARS
    AAR or ARS access to a trunk group overrides miscellaneous trunk 
    restrictions.
    nAbbreviated Dialing Privileged Group Number List
    A telephone user with authorization to access an Abbreviated Dialing 
    Privileged Group Number List can place calls to any number on that list. 
    COR assignments are not checked.
    nPrivileged System Number List
    A telephone user with authorization to access a Privileged System Number 
    List can place calls to any number on that list. COR assignments are not 
    checked.
    Conference
    The Conference button allows multiappearance telephone users to make up to six 
    party conference calls without attendant assistance. This button also allows 
    single-line telephone users to make up to three party conference calls without 
    attendant assistance.
    Considerations
    nA single-line telephone can have up to 6 parties on a conference call, if 
    each conferee adds another conferee. For example, one user can add a 
    party, who then adds a third party, and so on.
    nIf you do not allow trunk-to-trunk connections and a telephone releases 
    from a conference call (where all of the other parties were connected to the 
    conference via trunks), then all parties are disconnected.

    Features and technical reference 
    1310 Conference 
    20
    nIf an analog single-line set has Call Wait active and creates a conference 
    call, Call Wait is rendered inactive as long as the single-line set is on the 
    call. For example, caller A on an analog set talks to caller B, flashes to talk 
    to caller C, and flashes to conference B and C. Then, if caller D calls caller 
    A, Call Wait is denied.
    nUsers of DCP, Hybrid, and wireless phones can conference a call on hold. 
    If there is only one call on hold, no active call appearances, and an 
    available call appearance for the conference, a user can initiate the 
    conference process without taking the call out of hold. When the 
    Conference button is pressed, DEFINITY ECS assumes the conference is 
    for the call on hold, and the conference feature works as usual.
    If there is more than one call on hold, the user must make a call active in 
    order to include it in a conference. If the user presses the Conference button 
    with two or more calls on hold, DEFINITY ECS will ignore the conference 
    attempt since it will not know which call the user wants to conference. If 
    there are calls on hold and an active call, pressing the Conference button 
    will start the conference process for the active call.
    nYou can allow users to abort a conference operation that is in progress by 
    hanging up the phone. You set this parameter with the Abort Conference on 
    Hang-Up field on the Feature-Related System Parameters
     screen. When a 
    user hangs up the phone while trying to conference a call, the existing call 
    is placed on hold, and the conference operation is aborted. 
    Interactions
    nBridged Call Appearance
    A bridged call appearance can be used to make conference calls. A bridged 
    appearance can bridge onto a conference call only if there were never 6 
    parties on the conference. 
    nCall Vectoring
    A call to a VDN can be included as a party in a conference call only after 
    vector processing terminates for that call (for example, after a successful 
    route-to command).
    nClass of Restriction
    If the Restriction Override field is set to 
    all, the COR of the party being 
    added is always checked against the COR of the party controlling the 
    add-on, but the new party’s COR is not checked against any other 
    conferee’s CORs.

    Features and technical reference 
    1311 Restriction — Controlled 
    20
    nTrunk-to-Trunk Transfer
    When a multifunction telephone (BRI/Digital/Hybrid) dials sufficient 
    digits to route a call, but could route differently if additional digits were 
    dialed, the telephone does not recognize the Conference or Transfer 
    buttons. The user must delay dialing for 3 seconds or dial # to indicate that 
    the call can be routed based on the digits already dialed. The Conference or 
    Transfer buttons are then recognized and the switch completes the call.
    nVDN in a Coverage Path
    Calls in an established conference will not cover to a VDN.
    Once a call covers to a VDN, a conference cannot be established until the 
    call is delivered to an extension and vector processing ends.
    Related Topics
    Refer to the ‘‘
    Feature-Related System Parameters’’ on page 632 screen for the

    Restriction — Controlled
    Controlled Restrictions allow a telephone user with console permission to activate 
    or deactivate specific restrictions.
    Detailed description
    Use Controlled Restriction to administer the following restrictions:
    nOutward — The telephone cannot place calls to the public network.
    nTotal — The telephone cannot place or receive calls. (Allowed calls include 
    calls to a remote-access extension, terminating-trunk transmission tests, 
    and Emergency Access to Attendant calls.)
    Direct Inward Dialing (DID) calls are routed to the attendant or a recorded 
    announcement. All other calls receive intercept tone.

    Features and technical reference 
    1312 Restriction — Controlled 
    20
    nTermination — The telephone cannot receive any calls. Incoming calls are 
    routed to the attendant, are redirected via Call Coverage, or receive 
    intercept treatment.
    nStation-to-Station — The telephone cannot place or receive 
    station-to-station calls.
    nToll — The telephone cannot place toll calls but can place free local calls.
    NOTE:
    Toll Restriction may be substituted for either the outward or 
    station-to-station restrictions. Administer this option on the 
    ‘‘
    Feature-Related System Parameters’’ on page 632.
    To activate Controlled Restriction:
    1. Dial the group or extension feature access code.
    2. Dial the number for the type of restriction desired:
    — 1 for outward/toll
    — 2 for total
    — 3 for termination
    — 4 for station-to-station/toll
    3. Dial the extension (Attendant Control — Extension) or the Class of 
    Restriction (COR) for a group of telephones (Attendant Control — COR).
    Interactions
    nCall Coverage
    Controlled Restrictions are not checked for covering users.
    nCall Forwarding
    Controlled Restrictions for the forwarded-to extension are checked when 
    Call Forwarding All Calls is active.
    nClass of Restriction
    All telephones with the same COR are affected by a group restriction. 
    When a call is placed, both individual and group restrictions are checked.
    nPriority Call
    If a a station user or a Station-to-Station Restricted user activates priority 
    calling before they dial another station, they receive intercept tone. They 
    receive this tone whether you set Controlled Station to Station Restriction 
    on the Feature-Related System Parameters form to 
    y or to n.

    1313 Crisis Alert 
    20
    nUniform Call Distribution
    Calls dialed through the UDP are not restricted by Outward Restriction.
    Crisis Alert
    Crisis Alert notifies designated extensions when an emergency call is made, and 
    indicates the origin of the emergency call. This information allows the attendant 
    or other user to direct emergency-service response to the caller.
    When a user places an emergency call, the system notifies the designated 
    extensions with audible and visual alerting. Audible alerting sounds like an 
    ambulance siren. Visual alerting consists of flashing of the 
    CRSS-ALER T button 
    lamp and display of the caller name and extension.
    When crisis alerting is active at the attendant console, the console is in 
    position-busy mode so that no other incoming calls interfere with the emergency 
    call. The console can still originate calls. The attendant must press the 
    POSITION-BUSY button to unbusy the console and then the CRSS-ALER T button to 
    deactivate audible and visual alerting.
    Multiple emergency calls
    If an emergency call is made while another crisis alert is still active, the call will 
    be placed in queue. If you have administered the system so that all users must 
    respond, then every user must respond to every call. The calls may not necessarily 
    queue in the order in which they were made. 
    If you have administered the system so that only one user must respond, the first 
    crisis alert remains active at the phone where it was acknowledged. Any 
    subsequent calls are queued to the next available station in the order in which they 
    were made.
    Alerting a digital pager
    Crisis Alert to a Digital Pager allows users to receive crisis alert messages on a 
    pager. When a crisis alert call is originated in an emergency situation, a message 
    of 7 to 22 digits is sent to the pager and displays a crisis alert code, an extension or 
    room number, and a main number (if one is entered) so the pagee knows the 
    location from which the emergency call originated.  At the same time, an 
    emergency call connects over a CAMA trunk.  
    To receive a crisis alert message, you need to administer at least one attendant or 
    digital set with a 
    CRSS-ALRT button. With the Alert Pager field set to y, any station 
    with a 
    CRSS-ALRT button and a pager receives the correct alert.

    Features and technical reference 
    1314 Crisis Alert 
    20
    NOTE:
    The crisis alert call uses 2-4 trunks; 1 trunk for the actual call and 1-3 
    trunks to notify the pager(s) depending on the number of 
    administered pagers.
    Information about the alert can be viewed on the history report printed at the 
    journal printer and the emergency log.
    Considerations
    nOnly one crss-alert button is allowed per attendant console or digital 
    station.
    nConsoles without a crss-alert button do not receive emergency notification.
    nIf a user attempts to make an emergency call, but all trunks are busy, this 
    call will not generate an alert. If Outgoing Trunk Queuing is enabled for a 
    trunk group, the call will queue, but will not generate an alert. 
    Interactions
    nCentralized Attendant Service
    If CAS is enabled, the alert still goes to the local attendant.
    nTenant Partitioning
    If tenant partitioning is active, attendants only receive emergency 
    notification from callers within their partition. If there is no attendant 
    assigned to a partition from which an emergency call originates, the switch 
    still sends a record of the call to the journal printer. 
    nTerminal Self Administration 
    Those users who have the ability to administer their own phones do not 
    have the ability to disable a crisis alert button.

    1315 Dial Plan 
    20
    Dial Plan
    This is the system’s guide to digit translation. When the system receives dialed 
    digits, it must know what to expect next based on the digits received so far. For 
    example, if a user dials 4, the system must know how many more digits to expect 
    before the call is processed.
    All feature access codes, extensions and trunk access codes must be consistent 
    with the dial plan.
    Detailed description
    The dial plan provides information to the switch on what to do with dialed digits. 
    Tables define the intended use of a code beginning with a specific first digit or pair 
    of digits. These digits tell the system how many digits to collect before processing 
    the full digit string.
    For example, a digit string beginning with 8 may tell the system to wait for 4 more 
    digits because this is the first digit of a 5-digit internal extension. The choices of a 
    first digit are 0– 9, *, and #. Permissible codes and the allowable number of digits 
    are listed below.
    You can also administer a Uniform Dial Plan (UDP) as part of the dial plan to be 
    shared among a group of switches. If you establish a UDP, make all extensions the 
    same length (4 or 5 digits). So that calls route to the desired switch, a UDP 
    requires the following information:
    nA PBX code, which represents the first 1 to 5 digits of a 4-digit or 5-digit 
    extension and can range from 0 to 9xxxx with a maximum of 50,000 PBX 
    codes on G3r or 20,000 PBX codes on G3si/csi.
    nAn RNX, which is associated with the PBX code and is used to select an 
    AAR pattern for the call. This information is required for each PBX code. 
    The 3-digit RNX can be an AAR location code or, for ENP calls, an ENP 
    code.
    nA PBX ID (1 to 63), which represents a specific switch (optional).
    nWhether or not the PBX code is local to this system (optional).
    Considerations
    nYou cannot assign prefixed extensions longer than five digits (including 
    prefix) to intercom lists.
    nA trunk access code (TAC) and an extension can share a first digit only if 
    the extension is shorter than the TAC.

    1316 Dial Plan 
    20
    nAlthough extensions with the same first digit can have different lengths, 
    data-channel extensions must have the maximum number of digits to avoid 
    timeout problems for data calls that the switch automatically sets up, for 
    example, the Call Detail Recording (CDR) link.
    nAn extension and a Feature Access Code (FAC) can share the same first 
    digit only if the extension is longer as long as they are not used for 
    Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) 
    faxes. These extensions work only within the switch; they do not work as 
    remote uniform dialing plan (UDP) extensions.
    Interactions
    All dial-access features and services provided by the system require the dial plan.
    nAttendant Display and Telephone (Voice Terminal) Display
    Prefixed extensions display without the prefix. The return call button 
    causes the prefix to dial, even though it does not display.
    nISDN-BRI
    When an ISDN-BRI station dials sufficient digits to route a call, but the call 
    could route differently if additional digits were dialed, the station does not 
    recognize the Conference or Transfer buttons. The user must delay dialing 
    for 3 seconds or dial # to indicate that the call can be routed based on the 
    digits already dialed. The Conference or Transfer buttons then are 
    recognized and the switch completes the operation.
    nMF Signaling
    Flexible numbering is supported in countries using R2-MFC trunk 
    signaling without Group II tones. Different-length extensions can exist as 
    long as the extensions have different first digits.
    nProperty Management System (PMS)
    Remove prefixes before messages containing the extension are sent to the 
    PMS. Five-digit extensions do not exchange with PMS until modifications 
    are made to the PMS interface. 
    nUniform Dial Plan
    The following limitations apply to a distributed communications system 
    (DCS) environment:
    — Extensions that differ in length from the UDP do not distribute to 
    other switches.
    — If the first two digits of an extension correspond to the floor number, 
    floors cannot be serviced by more than one switch.
