Tenanting 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. Page 1
Tenanting 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. Page 3
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 TENANT 1 TENANT 25 TENANT 1 TRUNKS TENANT 25 TRUNK5 9293ROElFigure 2-l Tenant Connections to PABX Page 4

SECTKIN MITL9109-094-230-NAtrunks, but all of their calls will be directed to the common answering 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 Page 6
