    1547 Temporary Bridged Appearance 
    20
    Considerations
    nTemporary Bridged Appearance allows the desired party to bridge onto a 
    call without manually transferring the call, providing convenience of 
    operation and saving time.
    nTemporary Bridged Appearance does not provide any call originating 
    capability or the capability to answer another party’s calls. These 
    capabilities are provided by the Bridged Call Appearance feature.
    nIf two parties are bridged together on an active call with a third party, and if 
    the Conference Tone feature is enabled, conference tone is heard.
    nThe Bridged Call Appearance feature enhances Temporary Bridged 
    Appearance by allowing more than one call to an extension to be bridged 
    and by allowing calls to be originated from bridged appearances.
    Interactions
    nCall Coverage
    Calls redirected to Call Coverage maintain a temporary bridged appearance 
    on the called telephone if a call appearance is available to handle the call. 
    The called party can bridge onto the call at any time. The system can be 
    administered to allow a temporary bridged appearance of the call to either 
    remain at or be removed from the covering telephone after the principal 
    bridges onto the call. If two parties are bridged together on an active call 
    with a third party, and the bridging tone is administered to yes, all three 
    parties hear the bridging tone.
    nConsult
    Consult calls use the temporary bridged appearance maintained on the call. 
    At the conclusion of a consult call, the bridged appearance is no longer 
    maintained. If the principal chooses not to talk with the calling party, the 
    principal cannot bridge onto the call later.
    nConference and Transfer
    If a call has, or has had, a temporary bridged appearance; is conferenced or 
    transferred; and redirects to coverage again; a temporary bridged 
    appearance is not maintained at the conferenced-to or transferred-to 
    extension.
    nPrivacy — Manual Exclusion
    When Privacy — Manual Exclusion is activated, other users are prevented 
    from bridging onto a call. A user who attempts to bridge onto a call when 
    this feature is active is dropped.

    1548 Tenant Partitioning 
    20
    Tenant Partitioning
    (Not available with Offer B) Tenant Partitioning provides telecommunications 
    services to multiple independent groups of users through a single DEFINITY 
    ECS. Most commonly, Tenant Partitioning provides these services from a single 
    provider to multiple tenants of an office complex. This eliminates the need for 
    each tenant to purchase services separately, while still giving each tenant the 
    appearance of a dedicated DEFINITY ECS. You can also use this feature to 
    provide group services, such as departmental attendants, on a single-customer 
    DEFINITY ECS. Tenant Partitioning also allows you to assign a unique music 
    source for each tenant partition for callers who are put on hold.
    NOTE:
    If you use equipment that rebroadcasts music or other copyrighted materials, 
    you may be required to obtain a copyright license from, or pay fees to, a 
    third party such as the American Society of Composers, Artists, and 
    Producers (ASCAP) or Broadcast Music Incorporated (BMI). You can 
    purchase a Magic-on-Hold
    ® system, which does not require such a license.
    Detailed description
    Tenants are defined and assigned by you, the system administrator. You must have 
    the same authorization as that required for Class of Restriction (COR) 
    administration.
    Because some features are not partitioned, you must take care to administer these 
    features to prevent inter-tenant access. Refer to ‘‘
    Interactions’’ on page 1554 for a 
    list of these features.
    You must ensure that: 
    nAll tenants can call and be called by partition 1. This is the system default. 
    If you change this default some call types fail. For example, dial 0 fails, as 
    do SVN calls, ACA calls, etc.
    nAll stations in a call-pickup group are under control of the same tenant
    nAll stations with bridged appearances are under control of the same tenant
    nStations in different departments (for the purposes of attendant services) 
    can call each other
    Refer to DEFINITY ECS System Description to determine the number of tenants 
    that your system allows.
    You must assign a tenant partition number to each object (endpoint, virtual 
    endpoint, or other entity) that has an assigned COR. The exceptions are 
    authorization codes and fixed-assignment virtual endpoints.

    Features and technical reference 
    1549 Tenant Partitioning 
    20
    You administer Tenant Partitioning via the Tenant Partitioning screen; you need to 
    administer one form for each tenant partition. Begin the initial administration of 
    the Tenant Partitioning feature by completing the tenant partitioning form. Keep 
    in mind that you must specify an attendant group for each tenant that you define, 
    even if there are no consoles assigned to the attendant group. You must also assign 
    an attendant console to a tenant partition and you must assign a group number to 
    the Attendant Console screen.
    Tenant Partitioning capabilities
    Tenant Partitioning can provide the following services to tenants: telephone 
    equipment, building wiring, public and private network access, and attendant 
    services. In addition, the feature can provide a full range of DEFINITY ECS 
    capabilities to even the smallest tenant office, including Call Coverage, Remote 
    Access, Night Service Routing, and others. Tenants can also purchase DEFINITY 
    ECS adjuncts available on the switch, such as Call Management System (CMS) 
    activity reporting.
    Tenant Partitioning provides advantages to both the telecommunications service 
    provider and individual tenants:
    nShared resources offer enhanced services at lower cost to the tenant, with 
    increased profit for the service provider.
    nThe tenant has the appearance of a dedicated DEFINITY ECS without the 
    expense.
    nAll tenants can have attendant services.
    nA trained, full-time system administrator can install, administer, and 
    maintain the switch.
    With proper administration, tenant resources, including trunking facilities, and all 
    other switch endpoints can be protected from access by other tenants.
    Partitioning tenants
    The default for Tenant Partitioning is one universal tenant for the system. This 
    tenant, partition 1, is usually reserved for the service provider. By default it has 
    access to all facilities and any other tenant can access it.
    The service provider creates additional partitions based on tenant requirements. 
    When deciding which tenant partitions to create, remember:
    nYou can assign each switch endpoint to one and only one tenant partition. 
    And, you must pass each switch endpoint to a partition. For example, you 
    must assign each telephone, attendant console, trunk, and virtual endpoint, 
    such as an listed directory number (LDN) or vector directory number 
    (VDN), to a tenant partition.

    Features and technical reference 
    1550 Tenant Partitioning 
    20
    nMost tenant partitions are discrete, separate units. By default, the system 
    prevents all tenants, except partition 1, from accessing stations or trunking 
    facilities belonging to other tenants. However, you can change this default. 
    You can give explicit permission for one tenant to access another. For 
    example, you can allow tenant 6 to call tenants 9 and 16 only.
    NOTE:
    If a tenant has permission to call another tenant, it has access to every 
    endpoint belonging to that tenant. For example, if tenant 6 has 
    permission to call tenant 9, tenant 6 can also use any trunking 
    facilities present in tenant partition 9.
    nEven if two extensions are blocked from calling each other by Tenant 
    Partitioning restrictions, either extension can still reach the other by dialing 
    the extension’s Direct Inward Dialing (DID) number via the public 
    network.
    nIf any facilities are to be shared among tenants who do not want complete 
    access to each other’s facilities, you must group the shared facilities in a 
    separate partition. For example, if two tenants share a trunk, but do not 
    have direct access to each other’s telephones, that trunk will need to be 
    placed in its own partition so that both tenants can access it.
    It is also important to consider the following constraints and requirements of 
    access control, attendant services, music sources on hold, and network route 
    selection when you establish or assign partitions.
    Access control
    Features such as call coverage are limited by tenant-to-tenant access restrictions. 
    For example, suppose tenant 1 includes a telephone from tenant 2 in its coverage 
    path. If tenant 3 has permission to call tenant 1 but not tenant 2, a call from tenant 
    3 to tenant 1 skips the tenant 2 coverage point.
    You may also want to set up tenants with special access privileges. For example, 
    you might give a restaurant in an office complex permission to be called by any 
    other tenant. Likewise, permission to call or be called by other tenants is helpful 
    for building security or DEFINITY ECS administration or troubleshooting.
    You can also assign all CO trunks to one tenant partition that can then be accessed 
    by all other tenants.

    Attendant services
    Tenant Partitioning allows you to provide personalized attendant services to each 
    tenant.
    The system provides one principal and one night or day/night attendant per 
    attendant group. You assign each tenant an attendant group for service. Each 
    attendant group has a separate queue. Queue warning lamps remain dark when 
    Tenant Partitioning is active. However, information displayed when someone 
    presses a queue-status button reflects the status of the attendant-group queue. The 
    total number of calls queued for all tenants cannot exceed the system limit.
    Attendant groups may serve more than one tenant. In this case, the attendant 
    group cannot extend a call from one tenant via facilities belonging to another 
    tenant, unless the former tenant has permission to access the other’s facilities.
    Each tenant may have a designated night-service station. The system directs calls 
    to an attendant group in night service to the night-service station of the 
    appropriate tenant (when a night attendant is not available). When someone places 
    an attendant group into night service, all trunk groups and hunt groups that belong 
    to tenants served by that attendant group go into night service. In this case, the 
    system routes incoming calls to the night-service destination of the appropriate 
    tenant. Each tenant can have its own LDN night destination, trunk answer on any 
    station (TAAS) port, or night attendant.
    An attendant can specify that access to a trunk group is under attendant control if 
    the trunk group is assigned to a tenant served by that attendant’s group. The 
    system directs any valid user attempt to access the trunk group to the attendant 
    group serving the tenant.
    Network route selection
    You can place trunk groups belonging to different tenants in the same route 
    pattern. Calls routing to that pattern select the first trunk group in the pattern with 
    access permission by the calling tenant (subject to normal constraints).

    Tenant partitioning examples
    The following is a simple example of how you might administer Tenant 
    Partitioning in an office complex.
    You assign tenant partition 1, the universal tenant, as the service provider. All 
    other tenants can call and be called by the service provider.
    You assign tenant partitions 2–15 to individual businesses in the complex. You 
    maintain the system-default restrictions for these tenants. That is, tenants cannot 
    access telephones, trunking facilities, or other switch endpoints belonging to other 
    tenants.
    You assign tenant partition 16 to the restaurant in the building complex. You give 
    all tenants permission to call this tenant. However, to prevent the restaurant from 
    accessing trunks and other facilities belonging to tenants, you do not permit the 
    restaurant to call any other tenants.
    You assign tenant partition 17 to all Central Office (CO) trunk groups. You give 
    all tenants permission to call this tenant.
    You assign tenant partition 18 to a trunk group that tenants 3 and 7 want to share. 
    You give Tenants 3 and 7 access to this partition; you deny all other tenants 
    access. To prevent toll fraud, you do not allow tenant 18 to call itself.
    The Automatic Route Selection (ARS) route pattern can be the same for all 
    tenants. In this example, the trunk for tenant partition 18 (the private trunk shared 
    by tenants 3 and 7) is first in the route pattern. Tenant partition 17 is second. 
    Tenants 3 and 7 route first to partition 18 and then as a second choice to 
    partition 17. You deny all other tenants access to partition 18 and so the system 
    routes them directly to partition 17.
    All facilities that are not shared, including trunk groups, VDNs, telephones, 
    attendant consoles, and other endpoints, are assigned to the tenant partition that 
    they serve.
    Table 94
     summarizes the calling permissions for the different partitions. Yes 
    indicates that the partitions have permission to call and be called by each other; no 
    indicates that partitions cannot call or be called by each other.

    Detailed description of Multiple Music-on-Hold
    Tenant Partitioning allows you to assign each tenant a music source, unique to 
    each tenant partition, to be heard when a call is placed on hold. The tenant number 
    assigned to the destination extension usually determines which music source is 
    heard. This capability allows you to tailor the music or messages for the business 
    needs of each tenant partition.
    If the COR of the extension that places the call on hold permits music-on-hold, a 
    caller on hold hears the music source assigned to the partition at which the call 
    initially terminates. For example, if calls coming into the DEFINITY ECS route 
    first to an I
    NTUITY automated attendant that then routes the call to the appropriate 
    tenant partition, the caller on hold hears the music source of the I
    NTUITY 
    automated attendant, not the tenant partition to which it is routed. Likewise, if a 
    caller in tenant partition 2 makes an out-going call using tenant partition 1’s trunk 
    groups, the caller will hear the music source assigned to tenant partition 1. If the 
    COR of the called extension does not permit music on hold, however, the caller 
    hears nothing.

    The maximum number of music sources allowed is the same as the maximum 
    number of tenant partitions allowed; each music source can be used by one or 
    more tenant partitions.
    You can assign one of the following music-on-hold types to each tenant partition.
    Interactions
    Tenant-partition identification is not passed between switches. A network of 
    DEFINITY ECS systems does not enforce Tenant Partitioning restrictions without 
    special administration. For example, Tenant Partitioning on a network of 
    DEFINITY ECS systems does not enforce tenant-specific tie trunks.
    Administration of the following features requires special care to avoid undesired 
    intertenant access.

    Features and technical reference 
    1555 Tenant Partitioning 
    20
    The function of any feature that specifies a tenant partition is affected by 
    tenant-to-tenant restrictions, as follows.
    nAAR/ARS
    Do not confuse tenant partitions with Time-of-Day Plan Numbers and 
    Partition Groups in AAR/ARS. You can still use Time-of-Day Plan 
    Numbers and Partition Groups can still be used to select one of eight route 
    patterns for AAR/ARS routing when Tenant Partitioning is in effect.
    nAttendant and Attendant Group Features
    Tenant Partitioning creates multiple attendant groups. Attendant operations 
    such as direct-station or trunk-group select (DCS/DTGS) are subject to 
    tenant-to-tenant restrictions, both at selection time and at split time.
    All calls put on hold by an attendant from the attendant group hear the 
    music source from the attendant group.
    nAttendant Control of Trunk-Group Access
    An attendant group controls access only to trunk groups that belong to 
    tenants that are served by that attendant group.
    nAUDIX, DEFINITY AUDIX, and AUDIX Voice Power
    AUDIX voice and data ports are subject to the same tenant-to-tenant 
    restrictions as any other endpoint.
    AUDIX can restrict one group of subscribers from sending voice mail to 
    another group. The tenant-partitioning provider can create up to 10 
    different communities within each AUDIX that either have or do not have 
    permission to send voice messages across community boundaries.
    nAuthorization Codes
    Authorization codes are associated with classes of restriction. If you want 
    to have a set of authorization codes that is unique to a given tenant, you 
    could select a group of CORs for a that tenant and only assign those CORs 
    to objects in that partition. 
    nAutomatic Wakeup
    Wakeup music will be the music source assigned to the wakeup station’s 
    tenant partition.
    nBridged Call Appearance
    All stations with bridged call appearances should be administered to be 
    under control of the same tenant.

    nCall Coverage
    Tenant-to-Tenant access restrictions apply to coverage paths. If a tenant 
    cannot access a particular tenant, it cannot access that tenant as part of 
    another tenant’s coverage point.
    When an attendant is specified as part of a coverage path, the attendant 
    group of the called tenant, not the calling tenant, is accessed.
    When a call goes to coverage, is answered, and is put on hold, the music on 
    hold is the music source assigned to the tenant partition of the terminal that 
    was originally called.
    nCall Detail Record (CDR)
    CDR does not report the tenant partition number of the extension or trunk 
    group used. You must infer the tenant partition number from the extension 
    or trunk-group number.
    nCall Pickup
    Administer all stations in a call-pickup group to be under control of the 
    same tenant. The system supports Call Pickup only if the caller and the 
    called party can both call the pickup user. The caller and the called party do 
    not need to be in the same pickup group.
    nCall Vectoring/VDN
    A caller routed to a new destination by a vector step hears the music 
    assigned to the last active VDN. While a call is in vector processing, the 
    tenant number (TN) assigned to the active VDN (as determined by VDN 
    Override) determines the music source heard by callers on hold in most 
    circumstances. Note the following exception, however.
    If you use a wait-time  hearing  then  
    command where the  is a music source (assigned on the 
    Announcements/Audios Sources form), that music source will play instead 
    of the music source associated with the active VDN.
    The COR assigned to the VDN must permit music-on-hold.
    nCMS
    You can administer CMS to provide CMS reports to each tenant. You can 
    restrict each CMS login to control, on a permission basis, only those 
    entities that are assigned to a particular tenant. Outputs to separate printers 
    allow any tenant to print their own CMS reports. The tenant-partitioning 
    provider must administer CMS to provide this separation of tenant 
    permissions.
    nDial Access to Attendant
    When a tenant dials an attendant, it accesses its own assigned attendant 
    group.
