    1. INTRODUCTION1.01Tenanting is a feature which allows up to 25 tenants to share
    features and capabilities of the 
    SX-ZOO@ DIGITAL PABX. Some
    PABX features are enabled for each tenant through CDE, while other
    features are shared by all tenants.
    Reason for Reissue
    . 1.02This Section is reissued to describe tenanting and to explain
    how to use and program tenanting in an SX-200 DIGITAL PABX
    with Generic 1002 and Generic 1003 software.

    2. GENERAL DESCRIPTION.Overview
    2.01Tenanting is a very powerful and flexible feature available with
    the SX-200 DIGITAL PABX. Up to 25 tenants (or customers) may
    be defined. The PABX may be operated as a single tenant, or in a
    multiple customer or multiple tenant mode, by sharing services such
    as attendants or trunks. A typical installation may have several tenants,
    each with its own trunks, stations and attendant. Members of different
    tenants may be programmed to access each other (but not necessarily
    each other’s features) without going through the local Central Office,
    or may be totally independent of each other. The customer (or cus-
    tomers) can share the economies of a larger PABX, such as specialized
    trunks, leased services, and other features. Station Message Detail
    Recording (SMDR), described in Section 
    MITL9109-094-227-NA, allows
    equitable assessment of costs among all users.
    2.02A typical multiple tenant application is a company which oc-
    cupies a large building and has attendants and/or 
    sub-attendants in different areas, such as each floor or department. Some
    features, such as attendant recall, access the local attendant instead of
    the main attendant position, but other features such as WATS, ARS, Tie
    lines, or abbreviated dialing are available to all users.
    2.03A typical multiple customer application is a building served by
    one PABX, with telephone service for each customer (tenant)
    going through the PABX independently. When one customer calls an-
    other, the calling party must access one of its CO trunks and dial the
    customer’s listed directory number; the call will go through the CO and
    then appear as an incoming CO call at the called customer.
    Tenanting for Data Users
    2.04The 
    SX-ZOO DIGITAL PABX tenanting features are available for
    data users also; a typical application is to restrict access to
    certain computers, printers, and other data devices to data users in
    one or more specific internal departments, by placing all members into
    the same tenant and denying all other tenants access. Any computer
    resources which must be available to all users can be put into a tenant
    group to which everyone has access.
    Independent Consoles, Trunks, and Stations
    2.05The PABX is divided into distinct
    tenants;all 
    statiois,
    SUPERSETTM Telephones, trunks, and attendant consoles are
    assigned to a tenant as they are programmed into the PABX. The PABX
    can have a maximum of 11 consoles. Trunks and “Dial 
    0” calls are
    programmed to ring to only their associated attendant position. Out-
    going calls will seize only trunks within their same tenant, as shown in
    Figure 2-l.

    							SECTION MITL9109-094-230-NATenant 
    interconnection2.06 The PABX may be programmed to allow certain tenants to
    connect to each other internally within the system or to allow
    for sharing of services such as an attendant, console or trunks.
    2.07Each tenant may be allowed or not allowed to connect directly
    to any other tenant. For example, an attendant console to be
    shared by tenants 1, 2, and 3, can be assigned to tenant 25, and
    programmed to connect internally to tenants 
    1, 2, and 3; tenants 1, 2,
    and 3 may still be programmed to NOT connect to each other, as
    shown in Figure 2-2.
    2.08 Note the special case when tenant 1 can call tenant 2 but
    tenant 2 cannot call tenant 
    1. If SUPERSET 4TM telephone A in
    tenant 1 calls 
    SUPERSET 4 telephone B in tenant 2, and upon receiving
    no answer, sends the message to call Set A, Set B can return the call
    to Set A (by pressing its MSG, READ MSG, and CALL softkeys) even
    though tenant 2 is normally restricted from calling tenant 1.
    Identifying Tenants on Consoles and 
    SUPERSET Teiephones
    2.09 Attendant consoles or 
    SUPERSET telephones may be pro-
    grammed to provide a common answering point for incoming
    calls to all tenants, as well as calls that are unanswered by any tenant.
    Each tenantmaynot call the other tenants or access each other’s

    point. The incoming calls may be DID, DIL, or regular CO trunks.
    2.10When recalls are answered at a common answering point, the
    name of the tenant that did not answer is displayed as a NO
    ANSWER, so that the recall may be answered with an appropriate
    response. If the called party has a 
    SUPERSET 4 or a SUPERSET 4TMDNtelephone, that party’s name is displayed instead; however, the trunk
    group may be programmed to display the company name on the
    SUPERSET 4 telephone. Generic 1002 does not support tenant names.
    2.11The call rerouting point for all tenants may be two SUPERSET 4
    or 
    SUPERSET 4DN telephones, with each tenant having its own
    key for reroutes, as shown in Figure 2-3. A reroute to a busy line will
    camp on to that line, allowing queuing for each tenant’s calls.
    Local Night Switching
    2.12Tenants sharing the system may each require different system
    operation with respect to Day/Night mode. The PABX allows
    each tenant to switch into Night service independently, and to operate
    independently when it has switched to Night service. Figure 2-4 shows
    two typical examples.
    2.13An attendant with a console may switch to Night 1 or Night 2
    b.y pressing the FUNCTION key followed by the appropriate
    softkey.2.14A tenant with a 
    SUPERSET 4 telephone programmed as having
    night switching ability may press the SELECT FEATURES key
    and the NIGHT ANS 
    softkey to switch between NIGHT 1 ?, NIGHT 2 ?, or
    DAY ? service. The display shows NIGHT 1 SERVICE, NIGHT 2 SERVICE,
    or DAY SERVICE, according to the mode-which is currently active; each
    time that the NIGHT ANS 
    softkey is pressed, the display toggles be-
    tween the two inactive modes. A tenant with a 
    SUPERSET 4TMDNtelephone switches into night service by pressing the SUPERKEY, the
    MORE 
    sof-tkey twice, and the NIGHT ANSWER softkey. Press the softkeyto select the new mode of operation; if the EXIT 
    softkey is pressed, the
    current mode is retained, and no change occurs. The display either
    shows 
    NIGHTx SERVICE or flashes DAY SERVICE and then reverts to
    time and date display.
    Since call rerouting destinations and incoming CO trunks are pro-
    grammed for Day, Night 1, and Night 2, switching to Night service will
    automatically reroute all calls for that tenant, provided that the tenant
    is properly programmed in Form 6, Tenant Night Switching Control.
    2.15It may be desirable to have a console or a 
    SUPERSET 4 or a
    SUPERSET 4DN telephone (such as a night security desk) able
    to switch all tenants into Night 1 or Night 2 service. The security desk
    console may be programmed as a tenant that controls the Night status
    of tenants; when the security guard comes on duty and sets “Night 
    2”,all associated tenants switch into Night 2. If a tenant forgot to switch
    to Night service, and calls were not being rerouted, the status will be
