Description Allows a covering user to leave a message for the principal (called party) to call the calling party. Coverage Callback is activated by pressing the Cover Callback button after answering a coverage call. Details of how Coverage Callback is used in conjunction with Call Coverage are given in the Call Coverage feature description elsewhere in this section. Considerations Coverage Callback is useful whenever it is necessary to let the principal know that a call has been received from a certain party. Interactions Coverage Callback is only used in conjunction with the Call Coverage feature. Administration Coverage Callback is administered on a per-voice terminal b asis by the System Manager. The only administration required is to assign a Cover Callback button. Hardware and Software Requirements No a d ditional hardware or software is required.
Feature Descriptions 3-568Issue 3 March 1996 Coverage Incoming Call Identification (ICI) Feature Availability Coverage Incoming Call Identification is available with all Generic 3 releases. Description Allows multiappearance voice terminal users without a display in a Coverage Answer Group to i dentify an incoming call to that group. When an incoming call is directed to a Coverage Answer Group, the status lamp associated with the Coverage Answer Group button lights at group member’s voice terminal. Details of how Coverage ICI is used in conjunction with Call Coverage are given in the Call Coverage feature d escription, elsewhere in this section. Considerations With Coverage ICI, memb ers of Coverage Answer Groups do not have to have a display in ord er to i dentify incoming calls to the group. A second coverage call takes control of the Coverage ICI lamp and does not return control to the previous call when the second call is released. Interactions Coverage ICI is used only in conjunction with the Call Coverage feature. Administration Coverage ICI is administered on a per-voice terminal basis by the System Manager. The only administration required is to assign a Coverage Answer Group button. Hardware and Software Requirements No a d ditional hardware or software is required.
Customer-Provid e d Equip ment (CPE) Alarm Issue 3 March 1996 3-569 Customer-Provided Equipment (CPE) Alarm Feature Availability Customer-Provid e d Equip ment (CPE) Alarm is available with all Generic 3 releases. Description Provides the customer with an indication that a system alarm has occurred and that the system has attempted to contact a preassigned service organization about the problem. A customer-provided device, such as a lamp or a bell, is used to indicate the alarm situation. The system can be ad ministered so that the CPE Alarm will be activated during certain alarm levels. Only one of these levels may be administered. The CPE Alarm will be activated when an alarm occurs which corresp onds to, or is more severe than, the a dministered alarm a ctivation level. The levels for which the CPE Alarm can be activate d are listed below in descending order, b e ginning with the most severe. nMajor Alarm — This alarm is the most severe system alarm. A major alarm indicates that a vital system hardware component, which will seriously affect overall service, has failed. nMinor Alarm — This alarm indicates that a hardware component, which may affect service on a limited scale, has failed. nWarning Alarm — This alarm indicates that a problem may exist with a hardware component, b ut the problem does not affect service. The system can also be ad ministered so that the CPE Alarm is not activated under any of the previously listed alarm levels. The CPE Alarm is also activate d during a Power Failure Transfer (see the Power Failure Transfer feature elsewhere in this manual) regardless of the administered alarm activation level. Even if the system is a dministered so that the CPE Alarm is not activated at any alarm level, it will be activated during a Power Failure Transfer. The CPE Alarm is deactivated when the problem that caused the alarm is resolved. If there are multiple problems, the CPE Alarm will not b e deactivated until all problems, at or above the administered alarm activation level, are resolved. For more information, see DEFI NI TY Com munications System Generic 1 and Generic 3 Installation and Test , 555-230-104.
Feature Descriptions 3-570Issue 3 March 1996 Considerations The CPE Alarm feature lets customers use their own equipment to indicate an alarm condition. This indication lets the customer know when there is a problem with the system and when the problem has been resolved. Interactions The following features interact with the CPE Alarm feature. nPower Failure Transfer The CPE Alarm is always activated d uring a Power Failure Transfer regardless of the a dministered alarm activation level. Administration The CPE Alarm feature is administered on a per-system basis by the System Manager. Hardware and Software Requirements The only hardware required is the actual CPE Alarm d evice (lamp, bell, and so on). This d evice must be customer-provided and customer-installed. No a d ditional software is required.
Customer-Provid e d Equip ment (CPE) Alarm Issue 3 March 1996 3-571
Feature Descriptions 3-572Issue 3 March 1996 Data Call Setup Feature Availability Data Call Setup is available with all Generic 3 releases. Description Provides multi ple methods to set up a data call: nKeyb oard dialing nVoice terminal dialing nHayes AT command dialing nPermanent switched connections nAdministered connections nAutomatic calling unit interface (MPD and HSC) nHotline d ialing Typically, when a data terminal is available, keyboard dialing is more convenient and requires less steps; therefore, it should be used whenever possible. In a dd ition to d ata terminal d ialing and voice terminal dialing, the system accepts calls from other devices, such as a MPDM equipped with an ACU interface module. An analog modem interfaced with an ACU can also be used to provide dialing capability for a host computer. The Ad ministered Connections feature, described elsewhere in this chapter, may also b e used to establish a data call. This section describes the data call setup features for b oth DCP sets and ISDN BRI sets. Data Call Setup for DCP Modules Voice Terminal Dialing for DCP Data Modules Allows voice terminal users to originate and control data calls from the voice terminal. DCP voice terminal dialing must be used when the Data Terminal is not accessible for d ialing. The Transfer feature functions the same for d ata calls as it does for voice calls. The feature p ermits a user to set up a call using any unrestricted voice terminal and then transferring the call to a data endpoint. However, the primary way to establish d ata calls is with the multiappearance voice terminal Data Extension button(s). Any administrable feature b utton can be assigned as a Data Extension
Data Call Setu p Issue 3 March 1996 3-573 button in system administration. The Data Extension button provides one-touch access to a data module. The voice terminal Data Extension buttons control the One-Button Transfer to Data, Return-to-Voice, and Data Call Preindication o perations for the associated data module. These operations are discussed below. Multiple Data Extension buttons can be assigned to a multiappearance voice terminal, and that voice terminal can set up d ata calls for other data terminals. Also, a single d ata module can be accessed by a Data Extension button on a voice terminal. Only one Data Extension button can be administered for a single data module. Voice terminal dialing has the advantage that the user may hear the different types of network tones. For off-premises dialing, particularly for toll calls, the user may opt for voice terminal dialing, instead of keyboard dialing. The following options, either alone or combined, permit flexible procedures for establishing data calls: nOne-Button Transfer to Data Allows a user to transfer the call to the associated data module simply b y pressing the Data Extension button after the called data endpoint answers. This method is recommended for voice terminal data call setup. nReturn-to-Voic e Allows a user to return the data connection to the voice terminal. The user simply presses the Data Extension button associated with the busy data module. If the user hangs up following the return, the call is disconnected. If Return-to-Voice is affected by two voice terminal users, each through use of the Data Extension b utton associated with the two data endpoints of the call, then a voice call is established. Return of a data call to the voice terminal implies that the same (data) call will be continued in the voice mode, or transferred to another data endpoint. nData Call Preindication Allows the user, before dialing the distant data endpoint, to reserve the associated data module by pressing the Data Extension button. This ensures that a conversion resource, if needed, and the data module are reserved for the call. Use of Data Call Preindication before one button transfer to data is recommended when establishing data calls that use toll network facilities. Needed conversion resources are reserved before any toll charges are incurred. Data Terminal (Keyboard) Dialing for DCP Data Modules Allows a user to set up and disconnect data calls directly from a data terminal. A voice terminal is not needed. The voice terminal functions of switchhook and the audible call progress tones are replaced with keyboard dialing and text known as call progress messages. The message DIAL: prompts the user to enter the
Feature Descriptions 3-574Issue 3 March 1996 called data number manually from the keyboard, and RINGING informs the user the called data numb er is being rung. If the data call is placed in queue, the message WAIT, xx IN QUEUE is received (xx represents queue position). This queue number is updated by the system as the call moves up in the q ueue. The next table lists the call progress messages. To originate and disconnect a call using Data Terminal Dialing, the user presses BREAK on the terminal. [This is e quivalent to a voice terminal user lifting the handset (call origination) or hanging up (call disconnect).] If the terminal b eing used does not generate a 2-second continuous break signal, the user can press Originated/Disconnect on the data module. Then, the data terminal allows the user to enter digits from the data terminal keyboard, after the message DIAL: (which is the e quivalent of dial tone on a voice terminal). In a ddition to the numeral, #, and * characters found on a touch-tone pad, the dialing information may contain the following special characters: nSPACE, —, (, and) may b e used to improve legibility. These characters are ignored by the system during dialing. n+ character (wait) may be used to interrupt or suspend dialing until dial tone is received from the distant switch. n, (pause) character may b e used to place a 1.5-second pause in dialing (multiple, can be used). n% (mark) character may be used to indicate the following digits are for end-to-end signaling (touch-tone). This is required when the trunk is rotary. It is not required when the trunk is touch-tone. nUNDERLINE or BACKSPACE may b e used to correct previously typed characters on the same line. n@ may be used to delete the entire line and start over with a new DIAL: prompt. Each line of dialing information may contain up to 42 characters (the + and % characters count as two each). Examp les of dialing are as follows: nDIAL: 3478 nDIAL: 9+(201) 555-1212 nDIAL: 8, 555-2368 nDIAL: 9+555-2368+%9999+123 (remote access) Single-Line Dialing All of the d ialing information, including pauses and ignored characters, are typed on a single line. The line with the DIAL: prompt must be complete; that is, the dialing information must specify a complete call before the c arriage return or line feed.
Data Call Setu p Issue 3 March 1996 3-575 Single-line dialing is recommended if all dialing information can be entered on one line. Multiple-Line Dialing Automatically invoked when a single line of dialing information is incomplete. Multiple-line dialing is only used with off-premises calling. In multiple-line dialing, the DIAL: prompt follows on the next line when all of the dialing information of the previous line has been sent and dial tone has occurred; a d ditional dialing information is requested. This is a typical off-p remises dialing sequence: nDIAL: 9 nDIAL: (201) 555-2368 nRINGING nA NSW ER ED Alphanumeric Dialing Alphanumeric Dialing enhances Data Terminal Dialing by allowing a data terminal user to place a data call by entering an alphanumeric name. This capability makes Data Terminal Dialing both convenient and user-friendly. Instead of dialing a long string of numbers, the user can enter a simple alphanumeric name. For more detailed information, see the Alphanumeric Dialin g feature description, elsewhere in this chapter. Call Forwarding All Calls Call Forwarding All Calls allows incoming data calls to be redirected to another extension that is designated by the user. Activation/deactivation of the feature is done either by the attendant or by the forward ing party itself through the dialing of a feature access code. Default Dialing Default Dialing enhances Data Terminal (Keyboard) Dialing by allowing a data terminal user to place a data call to a preadministered destination by simply entering a carriage return at the DIAL: prompt. The d ata terminal user can still place calls to other destinations by entering the complete address after the DIAL: prompt (normal Data Terminal Dialing or Alphanumeric Dialing). For more detailed information, see the Default Dialing feature d escription elsewhere in this chapter. Administered Connections An Administered Connection is an end-to-end connection between two access endpoints or d ata endpoints that is automatically established by the system whenever the system is restarted or the Administered Connection is a dministered
Feature Descriptions 3-576Issue 3 March 1996 and due to be active. The attributes of these connections are user-defined. To administer Administered Connections, use the “ Administered Connection” form via the SAT. Once the ADM has been a dministered as one endpoint of an administered connection, the system waits for the scheduled time to set u p the connection. At the scheduled time, the system establishes the connection and maintains it for the length of time specified. Once the call is accepted, the set will enter into the continuous mo de for the length of time specified. If the switch is reboote d during the continuous connection, the connection will reinitiate the call setup. At any time that the connection drops (for example, disconnected cabling), the switch will reinitiate the call setup. Hotline Dialing Hotline Dialing is discussed in detail in the Data Hot Line feature description elsewhere in this manual. Table 3-50 shows call progress messages for DCP. Table 3-50. Call Progress Messages for Keyboard Dialing for DCP Displayed Message Application Meaning DIAL: Placing a call Equivalent to dial tone. Enter the desired number or feature access code followed by a carriage return or a line feed. RINGING Placing a call Equivalent to ringing tone. Called terminal (far-end) is ringing. BUSY Placing a call Equivalent to b usy tone. Called numb er is in use or out of service. ANSWERED Placing or receiving a callNotifies calling and called users that call has been answered. ANSWERED - NOT DA TA Placing a call Notifies calling and called users that call has been answered and a modem answer tone has not been detected. TRY AGAIN Placing a call Equivalent to reorder tone. System facilities are currently not available. DENIED Placing a call Equivalent to intercept tone. Call cannot be placed as dialed. ABANDONED Receiving a call Notifies called user that the calling user abandoned the call. NO TONE Placing a call Notifies user that tone was not detected. Continued on next page
