DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1537 Tenant Partitioning 20 Because some features are not partitioned, you must take care to administer these features to prevent inter-tenant access. Refer to ‘‘ Interactions’’ on page 1542 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. 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1538 Tenant Partitioning 20 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. 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1539 Tenant Partitioning 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1540 Tenant Partitioning 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1541 Tenant Partitioning 20 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. Table 94.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1542 Tenant Partitioning 20 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. Table 95. Music-on-Hold Types Type System Response for a caller placed on hold none silence tone system-wide administered tone music the music associated with the administered port. The number of possible music sources equals the number of possible tenant partitions. Each partition can have its own music source.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1543 Tenant Partitioning 20 Administration of the following features requires special care to avoid undesired intertenant access. nBridging nCall Pickup nCall Vectoring nControlled Restriction nFacility Busy Indication nFacility Test Calls nIntegrated Directory nInter-PBX Attendant Calls nMain/Satellite/Tributary nMalicious Call Trace nPersonal CO line nPrivate Networking (AAR) nService Observing nUniform Dial Plan 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1544 Tenant Partitioning 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1545 Tenant Partitioning 20 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. nEmergency Access to the Attendant When a tenant dials emergency access, it accesses its own assigned attendant group. nExpert Agent Selection (EAS) For agents in an EAS system, the Class of Restriction assigned to the logical agent ID (not the physical extension) determines whether callers on hold can hear music. nHunt groups The tenant number assigned to the hunt group extension determines the music source callers to the hunt group hear while they’re in queue or on hold. nIntercept Treatment When access to the attendant is designated as intercept treatment, the caller accesses their assigned attendant group.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1546 Tenant Partitioning 20 nMalicious Call Trace By default, Malicious Call Trace extensions are assigned to tenant partition 1. Therefore, if Malicious Call Trace is enabled, any telephone with permission to call tenant partition 1 can use it. nMultiple Listed Directory Numbers Each Listed Directory Number is assigned to a tenant partition. nMultiple Audio/Music Sources for Vector Delay When an audio source is specified by a wait-time hearing vector step, the audio source assigned to the tenant number of the active VDN is the one that plays. If you use a wait-time hearing then command where the is an audio source (assigned on the Announcements/Audios Sources form), that audio source will play instead of the one associated with the active VDN. For information on administering multiple audio sources see the DEFINITY ECS Call Vectoring/EAS Guide or DEFINITY BCS and Guestworks Call Vectoring Guide. nMusic-on-Hold Access When Tenant Partitioning is enabled, you can assign a unique source for music to each tenant. If Tenant Partitioning on the System-Parameters Customer-Options form is set to y, you must use the Music Sources form to administer music-on-hold. nNight Service Each tenant can have its own Listed Directory Number (LDN) night destination, Trunk Answer on Any Station (TAAS) port, or night attendant. nPC Interfaces You must assign each PC interface to a tenant partition. nPC/PBX Connections You must assign each PC/PBX Connection to a tenant partition. nPC/ISDN You must assign each PC/ISDN to a tenant partition. nRemote Access You must assign each Remote Access barrier code to a tenant. nTraffic Studies Traffic studies do not report the tenant partition number of the extension or trunk group used. You must infer the tenant partition number must be inferred from the extension or trunk-group number.
