Data Call Setu p Issue 3 March 1996 3-587 nModem Pooling: DEFINITY syst em Generic 3 requires either a TN758 Modem Pool circuit pack, or one digital port associated with a Trunk Data Module (either TDM or MTDM) and one analog port with analog modem for each conversion resourc e. A 7400A Data Module may be used in place of the TDM or MTDM. nData Line Data Module: Each port is c onnected to an ADU that converts to an RS-232 interface for connection to a data terminal. Keyb oard Dialing to off-premises data en d points requires the use of a tone detector circuit pa ck such as TN748C-Tone Detector, TN420C-Tone Detector, TN744C-Tone Detector/Call Classifier, or TN2182-Tone Clock/Detector/Generator. NOTE: The TN748C (Mu-law) and TN420 (A-law) support precise tone d etection. However, the TN744C or TN2182 only support p recise tone detection in countries that strictly adhere to U.S. standards. Therefore, if the detectors are used in countries that do not adhere to U.S. standards, the users may not exp erience p recise feedback during the data call setup. T748C and TN2182 support Mu-law. TN420C, TN744C, and TN2182 support A-law. Extensive use of features and services using tone detection may necessitate adding additional tone detector circuit packs. A TN726 Data Line circ uit pack can be used to provide direct access for data terminal users. No a d ditional software is required.
Feature Descriptions 3-588Issue 3 March 1996 Data Hot Line Feature Availability Data Hot Line is available with all Generic 3 releases. Description Data Hot Line provides for automatic nondial placement of a data call to an endpoint when the originator goes off-hook. It may be used for security purposes. Data Hot Line calls are automatically placed, by the system, from specified digital data endpoints to preassigned extension numbers or off-premises numbers. Hot Line originating endpoints are destinations connected to the system by a data module. The destination numb er is stored in the Abbreviated Dialing List. Considerations Data Hot Line offers fast and accurate call placement to commonly called data endpoints. Data terminal users that constantly call the same destination number can use Data Hot Line to automatically place the call by going off hook. The number of terminals that can be assigned Data Hot Line is not limite d, and the number of terminals that can b e assigned the same destination numb er is not limited. The only limit, if any, would be on the number of entries stored in the Abbreviated Dialing List. Interactions The following features interact with the Data Hot Line feature. nCall Forwarding — All Calls A Hot Line originator cannot activate Call Forwarding, since an off-hook intended to dial the Call Forwarding Feature Ac c ess Code will cause activation of the Data Call Hot Line feature instead. nData Terminal (Keyboard) Dialin g Any Terminal Dialing text may occur when a Data Hot Line Call is being established, with the exception of the inhibition of the initial d ial text message prompt normally given on off-hook for origination.
Data Hot Line Issue 3 March 1996 3-589 nSystem/ISN Ac cess A data call to an ISN data endp oint from a system digital d ata endpoint requires a two-stage dialing. A Hot Line Destination may be an extension number for an outgoing ISN group only, the Hot Line originator must then interact with ISN and manually enter the second address (data endpoint). Administration Data Hot Line is administered on per-data terminal b asis by the System Manager. The following item requires administration: nHot Line Destination Number — The preadministered Hot Line Destination must be stored in an abbreviated dialing list. This list can be a system list, group list, personal list, or enhanced list. Therefore, before this feature can be activated, users’ terminals need to be administered with an a b breviated dialing list that stores the Hot Line Destination. Then, each data module needs to specify the index number of the entry which stores the destination. The following fields from the “ Data Module” form are needed to activate the Data Hotline feature. — Special Dialing Option (default/hotline) — For Data Hotline, ‘‘hotline’’ must be selected. Default Dialing and the Data Hotline feature cannot both be assigned to an extension. — An Ab breviated Dialing List — One entry in the data mo dule’s a b breviated dialing list needs to store the d efault destination. — Dial Code (0-999) — An index to the entry of the a bbreviated dialing list that stores the default destination. Hardware and Software Requirements No a d ditional hardware or software is required.
Feature Descriptions 3-590Issue 3 March 1996 Data Privacy Feature Availability Data Privacy is available with all Generic 3 releases. Description NOTE: This feature is know as ‘‘Data Protection’’ in G2. Protects analog d ata calls from b eing d isturbed by any of the system’s overriding or ringing features. Data Privacy, when activated by a user, d enies the system the ability to gain access to, or to superimpose tones onto, the protected call. To activate this feature, the user dials the activation code at the beginning of the call. Considerations All systems have the capability for Data Privacy to p rovide interruption protection by denying the system the a bility to gain access to the protected, analog data call. Connections involving one or more digital d ata endpoints (d ata module) are automatically protected from receiving system-generated tones. In this case, the Data Privacy feature is not needed. Data Privacy, when activated, ap plies to both voice and data calls. The feature can be activated on Remote Access calls, b ut not on other incoming trunk calls. Data Privacy is canceled if the call is transferred, adde d to a conference call, bridged onto, or disconnected from by the activating user. Data Privacy can be activated on calls originated from attendant consoles. Interactions The following features interact with the Data Privacy feature. nAttendant Call Waiting and Call Waiting Termination If Data Privacy is activated, Call Waiting is denied. nBrid ged Call Ap pearance — Single-Line Voice Terminal When Data Privacy is activated or Data Restriction is assigned to a station involved in a b rid ged call and the primary terminal and/or brid ging user attempts to bridge onto the call, Data Privacy and Data Restriction are automatically overridden.
Data Privacy Issue 3 March 1996 3-591 nIntercom — Automatic and Dial An extension with Data Privacy or Data Restriction activated cannot originate an intercom call. Intercept tone is received when the ICOM button is pressed under this condition. nMusic-on-Hold Access If a call with Data Privacy activated is placed on hold, Music-on-Hold access is withheld to prevent the transmission of some musical tone which a connected data service might falsely interpret as a data transmission. nPriority Calls If Data Privacy is activated, Priority Calls to the activating extension number are denied on analog voice terminals. However, Priority Calls a p pear on the next available line a p pearance on multi-appearance voice terminals. nBusy Verification cannot be done when data p rivacy is active. Administration Data Privacy is activated by dialing a Data Privacy Feature Ac c ess Code (FAC) before originating the call. Permission to use the feature is assigned in COS. Hardware and Software Requirements No a d ditional hardware or software is required.
Feature Descriptions 3-592Issue 3 March 1996 Data Restriction Feature Availability Data Restriction is available with all Generic 3 releases. Description Protects analog d ata calls from b eing d isturbed by any of the system’s overriding or ringing features. Data Restriction, when administered to an extension numb er or trunk group, d enies the system the a bility to gain access to, or to superimpose tones onto, the protected call. This feature is administered at the system level to selected analog and multi-ap pearance voice terminals and trunk groups. Once administered, the feature is active on all calls to or from the associated terminal or trunk group. Considerations All systems have the capa bility for Data Restriction to prevent overriding or ringing features from interrupting the voice or data call. Connections involving one or more digital d ata endpoints (d ata modules) are automatically protected from receiving system-generated tones. In this case, the Data Restriction feature is not needed. Data Restriction a p plies to b oth voice and data calls. Also, Data Restriction cannot be assigned to attendant consoles. Data Restriction is removed from the current call if it is transferred, added to a conference call, bridged onto, or disconnected from by the restricted extension. Interactions The following features interact with the Data Restriction feature. nAttendant Call Waiting and Call Waiting Termination If Data Restriction is assigned, Call Waiting is denied. nIntercom — Automatic and Dial An extension with Data Privacy when activated cannot originate an intercom call. An extension with Data Restriction assigned cannot originate an intercom call. Intercept tone is received when the ICOM button is pressed under this condition.
Data Restriction Issue 3 March 1996 3-593 nMusic-on-Hold Access If a call with Data Restriction assigned is placed on hold, Music-on-Hold access is withheld to prevent the transmission of some musical tone which a connected data service might falsely interpret as a data transmission. nPriority Calls Priority Calls are not denied if the analog station is idle; Call Waiting (including Priority Call Waiting) is denied if the station is busy. However, Priority Calls a p pear on the next available line a p pearance on multi-appearance voice terminals. nBusy Verification cannot be done when Data Restriction is assigned. Administration Data Restriction is assigned on a per-line or trunk basis by the System Manager. Hardware and Software Requirements No a d ditional hardware or software is required.
Feature Descriptions 3-594Issue 3 March 1996 Data-Only Off-Premises Extensions Feature Availability Data-Only Off-Premises Extensions is available with all Generic 3 releases. Description Allows users to esta blish d ata calls involving DCE or DTE that is locate d remotely from the System site using DATAPHONE d i gital se rv i ce o r other private line data facilities. A Data-Only Off-Premises Extension uses an MTDM located on-premises. Communication with the remote data equipment is accomplished through the private line facility linking the on-premises MTDM and the remote data equipment. The Trunk Data Module and DCE or DTE constitute a digital data endpoint. Data calls to this type of data endpoint can be placed using Voice Terminal Dialing or Data Terminal (Keyboard) Dialing. Since there is no voice terminal at the remote site, data calls can be originated from the remote data terminal using Keyboard Dialing only. If computer-generated dialing is used on calls, it must follow the Keyb oard Dialing protocol. Considerations The systems have the capability for Data-Only Off-Premises Extensions to allow for data calls to remote DCE using DATAPHONE digital service or other private line data facilities. Data-Only Off-Premises Extensions provides digital data endpoints located off-premises through a Trunk Data Module located on-premises. Communications to or from this Trunk Data Module (and the associated off-premises equipment) must b e through an on-premises Processor Data Module or Digital Terminal Data Module. Communications between two Trunk Data Module are not supported. Likewise, Mo dem Pooling, which is conceptually similar to a Trunk Data Module, cannot be used on calls to or from a Data-Only Off-Premises Extension. Interactions The following features interact with the Data-Only Off-Premises Extensions feature.
Data-Only Off-Premises Extensions Issue 3 March 1996 3-595 nVoice Terminal Dialin g An on-p remises multiappearance voice terminal may have a Data Extension button associated with the Trunk Data Module used for a Data-Only Off-Premises Extension. The voice terminal user and the remote data equipment user share control of the data mo dule. Actions of the user at the voice terminal may affect the remote user. — One-Button Transfer to Data The on-premises voice terminal user can transfer a call to the Data-Only Off-Premises Extension. The Data Extension button on the voice terminal lights and the Call in Progress lamp on the data module lights during an established data call. — Return-to-Voic e If a data call has already been established, the voice terminal user may press the associated busy Data Extension button to transfer the call to the voice terminal. The data module associated with the Data Extension button is disconnected from the call. The Call in Progress lamp on the data mo dule goes dark. — Data Call Preindication The multia p pearance voice terminal user presses the idle associated Data Extension button to reserve the data mo dule. The data module is then busy to all users except the Preindicating user, including the remote user. When the data module is reserved, the lamp associate d with the Data Extension button winks at the preindicator’s voice terminal and lights at any other asso ciated voice terminals. A remote user receives the BUSY message when attempting to originate a call. Administration Data-Only Off-Premises Extensions is assigned on a p er-line b asis b y the System Manager. The following item requires administration: nDigital Line Circuit Pack — Assign the associated data module to a vacant port. Hardware and Software Requirements Requires a Trunk Data Module and one port on a TN754 Digital Line circuit pack (TN413, TN754B support A-law). No a d ditional software is required.
Feature Descriptions 3-596Issue 3 March 1996 DCS Alphanumeric Display for Terminals Feature Availability DCS is available with all Generic 3 releases except G3vs/G3s ABP. Description Allows calls to or from terminals equipp e d with alphanumeric displays to have transparency with respect to the display of call-related information. Calling Name Display is the presentation, on the called terminal’s alphanumeric display, of the name of the party who originated the call. Called Name Display is the presentation on the originatin g terminal’s display of the name of the party to whom the call is directed. Both displays provide more useful and precise information than such general identifiers as a trunk group name or an extension number. The transparency allows calling and called name information, plus miscellaneous identifiers (IDs) to be sent from a terminal on one node to a terminal on another node. Transparency in this area is limited by the type of systems at the endpoint nodes and at the intermediate node, if any. Considerations DCS Alphanumeric Display for Terminals gives the user considerable call handling capabilities by displaying call related information on calls to and from other DCS nodes. Calls to and from a DEFINITY system Generic 3 in a DCS network have Calling/Called Name Display transparency under the following conditions: nThe other party is at another DEFINITY syst em Generic 3 and the tandem node is a System 75 Version 3 or later, DEFINITY system Generic 1, DEFI NI TY s yst em Generic 3, System 85 Release 2 Version 2 or later, or a DEFI NI TY s yst em Generic 2.1. nThe call is not routed through a tandem System 85 Release 2 Version 1 or Enhanced DIMENSION PBX node. (Such calls will display only the extension number of the calling or called party.) On outgoing DCS calls, display of the called name may be delayed for a few seconds until the required information arrives from the distant node. The called name display only works between DEFI NI TY s yst em s Generic 1, Generic 3 systems, and System 75s.
