Night Service — Trunk Grou p Issue 3 March 1996 3-937 Night Service — Trunk Group Feature Availability This feature is available with all Generic 3 releases. Description The Trunk Group Night Service feature allows an attendant or a designated voice terminal user to individually assign a trunk group or all trunk groups to the night service mode. Specific trunk groups (individually) assigned to Trunk Group Night Service are in the In dividual Trunk Night Service Mode. In this mode, incoming calls made on a sp ecific trunk group are redirected to its designated Night Service Extension (NSE). Incoming calls on the trunk groups not assigned to Trunk Group Night Service are be processed normally. The specific trunk groups can be assigned to Trunk Group Night Service by pressing the individual Trunk Night Service b utton(s) on the attendant console or a voice terminal. All trunk groups can be assigned to the night service mode at the same time. In this arrangement, the trunk groups are in the System Night Service mode. Any incoming calls made on the trunk groups are redirected to their designated NSE. All trunk groups can be assigned to System Night Service by pressing the System Night Service button on the principal attendant console or a designated voice terminal. Considerations The Trunk Group Night Service feature gives a d de d flexibility to attendants and designated voice terminal users who are responsible for activating or deactivating all, or individual, trunk groups at various times. All incoming calls on individual or system Night Service trunk groups goes to the trunk group’s NSE unless the trunk group member has its own Trunk Group Member Night Destination, in which case the calls are redirected to that night destination instead of the trunk g roup’s NSE. Calls already in progress on a trunk group, such as talking, on hold, or waiting in queue on a trunk group, are not affected when the individual Trunk Group Night Service or System Night Service feature is activated b y the attendant or a voice terminal user. Trunk Group Night Service and System Night Service b oth work independently of each other. Activation or d eactivation of one of these night service features d oes not affect the other. Specific situations are described below: nWhen System Night Service is d eactivated, trunks with individual Trunk Group Night Service still activated remain in night service.
Feature Descriptions 3-938Issue 3 March 1996 nWhen System Night Service is activated, trunks controlled by individual Trunk Group Night Service buttons remain in day service. nTrunks with individual Trunk Group Night Service can be taken out of Night Service even though the rest of the system remains in Night Service. nTrunks with individual Trunk Group Night Service can be put into Night Service even though the rest of the system remains in day service. nTrunk groups assigned to individual Trunk Group Night Service are not reassigned to System Night Service when the System Night Service feature is activated. Those trunk groups that are not currently assigned to Trunk Group Night Service are assigned to System Night Service. If a trunk is added to a trunk g roup while that trunk group is in Trunk Group Night Service, the trunk is brought up in night service. Individual Trunk Group Night Service does not apply to DID trunk groups. If Night Service is activated for a trunk group, and a power failure o c curs, the trunk group automatically returns to the Night Service mode. If for some reason, a voice terminal with a trunk-ns button remains out-of-service after a system reboot and later comes back in service, the trunk-ns lamp shows the trunk status within 10 seconds of coming back in service. For example, a voice terminal with a trunk-ns button may be unplugg e d when the system is rebooted. If the voice terminal is later plu g ged back in, the trunk status is shown on the trunk-ns b utton within 10 seconds. Interactions The following features interact with the Night Service — Trunk Group feature. nLDN In the System Night Service mode, all incoming LDN calls, except those using DID trunks, which have activated night service are redirected to their corresp onding trunk group’s NSE. Incoming LDN calls using DID trunks are directed to the Night Console Service, Night Station Service, or Trunk Answer From Any Station feature, respectively, whichever applies first. Non-LDN DID trunk calls terminate at the dialed extension. nCall Forwarding — All Calls If the Trunk Group Night Service mode and the trunk group’s NSE has Call Forwarding — All Calls a ctivated, the night service c alls terminating to that NSE are forwarded to its designated extension. nForced First Announcements An intera ction occurs with system night service and Forced First Annoucement. For example, if hunt group A has a forced first announcement (delay =0), assign the incoming CO trunk to terminate at
Night Service — Trunk Grou p Issue 3 March 1996 3-939 hunt group A. Assign the incoming trunk’s night service destination to be another hunt group (hunt group B). Assign a night service button to the attend ant. With night service activated on the attendant, the incoming CO call routes to the night service destination hunt group B and d oes not play the Forced First Announcement of the incoming destination’s hunt group A. Without night service active, the incoming CO call routes to the incoming d estination hunt group A and plays the Forced First Announcement. Administration Individual Trunk Group Night Service is a dministered on a voice terminal b asis or attendant console. The following items require administration: nAssign ‘‘trunk-ns’’ button(s) to d esignated voice terminal(s). Up to three buttons c an be assigned to voice terminals in each trunk group. The trunk group number must be assigned for each button. If a ‘‘trunk-ns’’ button is assigned for an existing trunk, it is update d immediately to show the status of the trunk. nAssign ‘‘trunk-ns’’ button(s) to attendant console(s). Three buttons per attendant console are allowed. The trunk group number must be assigned for each button. nPermission to allow attendant seeking calls other than DID LDP calls redirect to the DID Listed Directory Number (LDN) night extension, if desired. The system can have extension numb ers for Night Service per trunk group member that take precedence over the one assigned to the group. The system can have Trunk Group Night Service and split Night Service at the same time, but the calls are redirected to the trunk group’s NSE before it goes to the hunt group/split’s NSE. Hardware and Software Requirements No a d ditional hardware or software is required.
Feature Descriptions 3-940Issue 3 March 1996 Off-Premises Station Feature Availability This feature is available with all Generic 3 releases. Description Allows a voice terminal located outside the building where the switch is located to be connected to the system. If CO trunks are used, the voice terminal must be analog and must b e FCC-registered (or, outside the US, registered by the appropriate governmental agency). Considerations Off-Premises Stations are useful whenever it is necessary to have a voice terminal located away from the main location. The maximum loop distance for Off-Premises Stations is 20,000 feet (6093.34 meters) without repeaters. Interactions The Distinctive Ringing feature might function improperly at an Off-Premises Station due to the distance. However, the Distinctive Ringing feature can be disabled when the Off-Premises Station is a dministered. If the Distinctive Ringing feature is not used with an Off-Premises Station, the terminal will receive one-burst ringing for all calls. Administration Off-Premises Stations are administered by the System Manager. Off-Premises Stations are a dministered the same as on-premises voice terminals with the following exceptions: nFor voice terminals used as Off-Premises Stations the “ Off-Premises Station” field must be a dministered as yes. nFor voice terminals used as Off-Premises Stations the “ R Balance Network” field must be completed.
Off-Premises Station Issue 3 March 1996 3-941 Hardware and Software Requirements Requires cross-connecting capabilities or one port on a TN747 or TN464B/C/D DS1 Tie Trunk circuit pack for each interface to be provided. NOTE: TN767 supports Mu-Law, TN464B supports A-Law, and TN464C/D supports both Mu-Law and A-Law. No a d ditional software is required
Feature Descriptions 3-942Issue 3 March 1996 3 PC Interface Feature Availability This feature is available with all Generic 3 releases. Description The PC (Personal Com puter) Interface feature consists of the PC/PBX Connection, the PC/PBX Platforms, and PC/ISDN Platform product family. These products are used with the and DEFINITY Sy stem Generic 3 switches to provide users of AT&T PCs and other IBM comp atible PCs fully integrated voice and data work station capabilities. PC/PBX Connection is a voice and data call management application. NOTE: See the AT&T Catalog or your account team for other applications available on the platforms. The platforms consist of PC interface cards and open voice and data Applications Programming Interfaces (API). These APIs allow a variety of applications to operate on the PC and communicate with the switch. Configurations Several different configurations are available for the PC Interface feature. For convenience in referencing, these break d own into three groups. Groups 1 and 2 use the DCP (Digital Communications Protocol) while Group 3 uses the ISDN-BRI (Basic Rate Interface) protocol. Configuration Group 1 Group 1, consists of those DCP PC/PBX configurations that use a PC Cartridge in a 7404D voice terminal (manufacture discontinued) to communicate with the switch. This group was formerly called p ackage 1 (now Release 3.0X) and package 2. Group 1 is shown in Figure 3-26. (Please note that this configuration is not available for new installations.)

PC Interface Issue 3 March 1996 3-945 Figure 3-28. ISDN—BRI PC Interface Configuration (Group 3) Switch Features and Services PC Interface users have multiple appearances (d epending on the software application used) for their assigned extension. One or more of these appearances can be designated for use with data calls. With the ISDN-BRI version, up to four separate PC/ISDN Interface Cards can be used on the same PC. Each interface card used can be assigned a separate extension numb er, and each of these extension numbers can have multiple appearances. The availability of specific features depends on the class of service of the assigned extension and the system class of service for the switch. Modem Pooling should be provided to ensure general availability of off-net data calling services. PC Features and Services nPC/PBX Connection Provides an integrated voice and data workstation interface from the System to an AT&T PC 6300 or other comp atible computer.
