DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 397 Data Call Setup 15 ISDN-BRI data modules Data-terminal dialing A user can set up and disconnect data calls directly from a data terminal without using a telephone as follows: 1. The user presses ENTER a few times. If the CMD: prompt does not appear, the user presses BREAK A + T at the same time, and then presses ENTER. 2. At the CMD: prompt, the user types and presses ENTER. 3. To disconnect, the user enters +++. At the CMD: prompt, the user types end and presses ENTER. Telephone dialing To make a data call, an ISDN-BRI phone user presses the data button on the terminal, enters the number on the dial pad, and then presses the data button again. The following data functions are not available on ISDN-BRI phones: nOne-Button Transfer to Data nReturn-to-Voice nData Call Preindication nVoice-Call Transfer to Data and Data-Call Transfer to Voice The system handles all presently defined BRI bearer data-call requests. Some capabilities that are not supported by Lucent terminals are provided by non-Lucent terminals. If the switch does not support a capability, a proper cause value returns to the terminal. BRI terminals receive a cause or reason code that identifies why a call is being cleared. The BRI data module converts certain cause values to text messages for display. In a passive-bus multipoint configuration, the system supports two BRI endpoints per port, thus doubling the capacity of the BRI circuit pack. When you change the configuration of a BRI from point-to-point to multipoint, the original endpoint does not need to reinitialize. Only endpoints that support service profile identifier (SPID) initialization can be administered in a multipoint configuration. Analog modems When a telephone user places a data call with a modem, the user dials the data-origination access code assigned in the system before dialing the endpoint.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 398 Default Dialing 15 Considerations nA BRI phone cannot call a data terminal, and a data terminal cannot call a BRI phone. Interactions nAbbreviated Dialing Only 22 of the 24 (maximum) digits in an abbreviated-dialing number are available for keyboard dialing. The remaining two digits must contain the wait indicator for tone detection. nCall Coverage A hunt group made up of data endpoints cannot be assigned a coverage path. nCall Detail Recording CDR records the use of modem pools on trunk calls. nCall Forwarding All Calls Calls received by a data module can be forwarded. Activate Call Forwarding All Calls with data-terminal (keyboard) dialing. If the forwarded-to endpoint is an analog endpoint and the caller is a digital endpoint, modem pooling is activated automatically. nPooled Modems with Hunt Groups UCD can provide a group of data modules or analog modems for answering calls to connected facilities (for example, computer ports). nWorld-Class Tone Detection Multiple-line data-terminal dialing is supported if the administered level of tone detection is precise. You can administer tone-detection options. The message that Data Call Setup sends to users varies according to the option. If the option is not set to precise, and a data call is set up over an analog trunk, messages describing the status of the called endpoint (for example, RINGING, BUSY, TRY AGAIN) change according to which tone-detection option is selected. Default Dialing Default Dialing provides data-terminal users who dial a specific number the majority of the time a very simple method of dialing that number. Normal data terminal dialing and alphanumeric dialing are unaffected.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 399 Alphanumeric Dialing 15 Default Dialing enhances data terminal (keyboard) dialing by allowing a data-terminal user to place a data call to a preadministered destination by either pressing a Return at the DIAL: prompt (for data terminals using DCP data modules) or typing d and pressing RETURN at the CMD: prompt (for data terminals using ISDN-BRI data modules). The data-terminal user with a DCP data module can place calls to other destinations by entering the complete address after the DIAL: prompt (normal data terminal dialing or alphanumeric dialing). The data-terminal user with an ISDN-BRI data module can place calls to other destinations by typing d, a space, the complete address, and press RETURN after the CMD: prompt. NOTE: DU-type hunt groups connecting the system to a terminal server on a host computer have hunt-group extensions set to no keyboard dialing. For the AT command interface supported by the 7400A/7400B/8400B data module, to dial the default destination, enter the ATD command (rather than press return). Administering Default Dialing 1. You can use an abbreviated dialing list for your default ID. Refer to ‘‘ Abbreviated Dialing’’ on page 1129 for more information. 2. On the Data Module screen, administer the following fields: nSpecial Dialing Option as default. nAbbreviated Dialing List, enter the list to use. nAD Dial Code. Alphanumeric Dialing Alphanumeric Dialing enhances data-terminal dialing by allowing users to place data calls by entering an alphanumeric name rather than a long string of numbers. For example, a user could type 9+1-800-telefon instead of 9+1-800-835-3366 to make a call. Users need to remember only the alpha-name of the far-end terminating point. Alphanumeric Dialing allows you to change a mapped string (digit-dialing address) without having to inform all users of a changed dial address. Users dial the alpha name.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 400 Data Hotline 15 When a user enters an alphanumeric name, the system converts the name to a sequence of digits according to an alphanumeric-dialing table. If the entered name is not found in the table, the system denies the call attempt and the user receives either an Invalid Address message (DCP) or a Wrong Address message (ISDN-BRI). Because data terminals access the switch via DCP or ISDN-BRI data modules, dialing procedures vary: nFor DCP, at the DIAL: prompt users type the alphanumeric name and press RETURN. nFor ISDN-BRI, at the CMD: prompt users type d, a space, and the alphanumeric name, and press RETURN. More than one alphanumeric name can refer to the same digit string. Administering Alphanumeric Dialing 1. On the Alphanumeric Dialing Table screen, administer the Alpha-name and Mapped String fields. Refer to ‘‘ Alphanumeric Dialing Table’’ on page 478 for more information. Considerations NOTE: Alphanumeric dialing does not apply to endpoints with Hayes modems. Data Hotline Data Hotline provides for automatic-nondial placement of a data call preassigned to an endpoint when the originating switch goes off-hook. Use for security purposes. Administering Data Hotline 1. You can use an abbreviated dialing list for your default ID. Refer to ‘‘ Abbreviated Dialing’’ on page 1129 for more information. 2. On the Station screen, administer the following fields. Refer to ‘‘ Station’’ on page 882 for more information. nAbbreviated Dialing List nSpecial Dialing Option nHot Line Destination
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 401 Data Privacy 15 3. On the Data Module screen, administer the Abbreviated Dialing List1 field. The system automatically places Data Hotline calls to preassigned extensions or off-premises numbers. Calling terminals are connected to the system by a data module. Users should store the destination number in the abbreviated dialing list for future reference. Interactions nCall Forwarding — All Calls A Data Hotline caller cannot activate both Call Forwarding and Data Hotline. Dialing the Call Forwarding feature access code (FAC) causes activation of the Data Hotline instead. Data Privacy Data Privacy protects analog data calls from being disturbed by any of the system’s overriding or ringing features. Administering Data Privacy 1. Choose either of the following: nOn the Feature Access Code screen, administer the Data Privacy Access Code field. Refer to ‘‘ Feature Access Code’’ on page 619 for more information. nOn the Class of Service screen, administer the Data Privacy field. Refer to ‘‘ Class of Service’’ on page 532 for more information. 2. On the Station screen, administer the Class of Service field. Refer to ‘‘ Station’’ on page 882 for more information. To activate this feature, the user dials the activation code at the beginning of the call. Considerations nData Privacy applies to both voice and data calls. You can activate Data Privacy on Remote Access calls, but not on other incoming trunk calls. Data Privacy is canceled if a user transfers a call, is added to a conference call, is bridged onto a call, or disconnects from a call. You can activate Data Privacy on calls originated from attendant consoles.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 402 Data Restriction 15 Interactions nAttendant Call Waiting and Call Waiting Termination If Data Privacy is active, Call Waiting is denied. nBridged Call Appearance — Single-Line Telephone If you activate Data Privacy or assign Data Restriction to a station involved in a bridged call and the primary terminal or bridging user attempts to bridge onto the call, this action overrides Data Privacy and Data Restriction. nBusy Verification Busy Verification cannot be active when Data Privacy is active. nIntercom — Automatic and Dial An extension with Data Privacy or Data Restriction active cannot originate an intercom call. The user receives an intercept tone. nMusic-on-Hold Access If a user places a call with Data Privacy on hold, the user must withhold Music-on-Hold to prevent the transmission of tones that a connected data service might falsely interpret as a data transmission. nPriority Calls If a user activates Data Privacy, Priority Calls are denied on analog telephones. However, Priority Calls appear on the next available line appearance on multiappearance telephones. Data Restriction Data Restriction protects analog-data calls from being disturbed by any of the system’s overriding or ringing features or system-generated tones. Data Restriction applies to both voice and data calls. Once you administer Data Restriction for an analog or multiappearance telephone or trunk group, the feature is active on all calls to or from the terminal or trunk group. NOTE: Do not assign Data Restriction to attendant consoles.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 403 Data Restriction 15 Administering Data Restriction 1. On the Station screen, set the Data Restriction field to y. Refer to ‘‘ Station’’ on page 882 for more information. 2. Choose one of the following trunk groups and set the Data Restriction field to y. Refer to ‘‘ ISDN trunk group’’ on page 738 and ‘‘Trunk Group’’ on page 967 for more information. nAccess nAdvanced Private-Line Termination (APLT) nCircuit Pack (CP) nCustomer-Premises Equipment (CPE) nDirect Inward Dialing (DID) nForeign Exchange (FX) nIntegrated Services Digital Network-Primary Rate Interface (ISDN-PRI) nRelease-Link Trunk (RLT) nTandem nTie nWide Area Telecommunications Service (WATS) Interactions - Data Restriction nAttendant Call Waiting and Call Waiting Termination If Data Restriction is active, Call Waiting is denied. nBusy Verification Busy Verification cannot be active when Data Restriction is active. nIntercom — Automatic and Dial An extension with Data Privacy or Data Restriction activated cannot originate an intercom call. The user receives an Intercept tone. nMusic-on-Hold Access If a user places a call with Data Restriction on hold, The user must withhold Music-on-Hold to prevent the transmission of tones that a connected data service might falsely interpret as a data transmission.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 404 Data-Only Off-Premises Extensions 15 nPriority Calls Priority Calls are allowed if the analog station is idle. Call Waiting (including Priority Call Waiting) is denied if the station is busy. However, Priority Calls appear on the next available line appearance on multiappearance telephones. nService Observing A data-restricted call cannot be service observed. Data-Only Off-Premises Extensions Data-Only Off-Premises Extensions allows users to make data calls involving data communications equipment (DCE) or digital terminal equipment (DTE) located remotely from the system site. A Data-Only Off-Premises Extension uses an on-premises modular trunk data module (MTDM). The system communicates with remote data equipment through the private-line facility linking the on-premises MTDM and the remote data equipment. Users can place data calls to this type of data endpoint using Telephone Dialing or Data Terminal (Keyboard) Dialing. Since there is no telephone at the remote site, originate data calls from the remote data terminal using Keyboard Dialing only. Administering Data-Only Off-Premises Extensions 1. On the Processor/Trunk Data Module screen, administer all fields. Refer to ‘‘ Data modules’’ on page 558 for more information. Considerations nThe system does not support communications between two TDMs. Modem Pooling is similar to a TDM, it cannot be used on calls to or from a Data-Only Off-Premises Extension. Interactions nTelephone Dialing An on-premises multiappearance telephone may have a Data Extension button associated with the TDM used for a Data-Only Off-Premises Extension. The telephone user and the remote user share control of the data module. Actions of the user at the telephone may affect the remote user.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 405 Data Modules — general 15 — 1-Button Transfer to Data The telephone user can transfer a call to the Data-Only Off-Premises Extension. The Data Extension button lamp on the telephone lights and the Call in Progress lamp on the data module lights during a data call. — Data Call Preindication The multiappearance telephone user presses the idle associated Data Extension button to reserve a data module. The data module is busy to all other users. When the user reserves a data module, the lamp associated with the Data Extension button winks and lights at any other associated telephones. A remote user receives the BUSY message when attempting to originate a call. — Return-to-Voice To establish a data call, the telephone user presses the associated busy Data Extension button to transfer the call to the telephone. The data module associated with the Data Extension button is disconnected from the call. The Call in Progress lamp on the data module goes dark. Data Modules — general A Data Module is a connection device between a basic-rate interface (BRI) or digital-communications protocol (DCP) interface of the switch and data-terminal equipment (DTE) or data-communications equipment (DCE). The following types of data modules can be used with the system: nAnnouncement data module nData line data module nProcessor/trunk data module (P/TDM) nNetcon data module (G3si configurations only) Refer to DEFINITY ECS Administration for Network Connectivity for more information. nProcessor interface data module (G3si configurations only). Refer to the DEFINITY ECS Administration for Network Connectivity for more information. nSystem port data module (G3r configurations only) nX.25 data module (G3r configurations only). Refer to DEFINITY ECS Administration for Network Connectivity for more information. n7500 data module nWorld Class BRI data module
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing data calls 406 Data Modules — general 15 nEthernet data module. Refer to DEFINITY ECS Administration for Network Connectivity for more information. nPoint-to-Point Protocol (PPP) data module. Refer to DEFINITY ECS Administration for Network Connectivity for more information. NOTE: The 51X series Business Communications Terminals (BCTs) are not administered on the Data Module screen. The 510 BCT (equivalent to a 7405D with a display and built-in DTDM), 515 BCT (equivalent to a 7403D integrated with 7405D display module function, data terminal and built-in DTDM), and the 7505D, 7506D, and 7507D have a DCP interface but have built-in data module functionality. Both are administered through the Station screen. Detailed description of data modules TTI allows data modules without hardware translation to merge with an appropriate data module connected to an unadministered port. The unadministered port is given TTI default translation sufficient to allow a terminal connected to the data module (connected to the port) to request a TTI merge with the extension of a data module administered without hardware translation. NOTE: TTI is not useful for Announcement and X.25 hardware. Administration Without Hardware supports PDM, TDM, Data-Line, Announcement, and X.25 data modules. NOTE: The 513 BCT has an EIA interface rather than a DCP interface (no built in data module, attachable telephone, or telephone features). The 513 BCT is not administered; only the data module to which the 513 BCT is connected is administered. 7400A/7400B+/8400B+ Data Module Use the 7400A data module instead of an MTDM when you support combined Modem Pooling. The 7400A data module supports asynchronous operation at speeds up to 19200-bps, and provides a DCP interface to the switch and an EIA 232C interface to the associated modem. The 7400A operates in stand-alone mode as a data module. 7400B+ and 8400B+ data modules support asynchronous-data communications and operate in stand-alone mode for data-only service or in linked mode, which provides simultaneous voice and data service. The 7400B+ and 8400B+ provide voice and data communications to 7400D series phones and 602A1
