Integrated Services Digital Network (ISDN) — Primary Rate Interface Issue 3 March 1996 3-817 switch is a public network switch, it may be necessary to perform some administration on that switch, or to subscribe to a CPN/BN delivery feature. For example, CPN/BN delivery from the AT&T Switched Network is either on a subscription basis (that is, on all calls) or on a per call request basis. Per call CPN/BN requests at the AT&T Switched Network are administered on the “ ISDN Trunk Group” form. In either case, four types of CPN/BN delivery may be requested (CPN only, BN only, CPN preferred, and BN preferred). Hardware and Software Requirements For G3vs/G3s PBP, G3i-global and G3i: nA TN767 or TN464C/D/E DS1 circ uit pack is required for assignment of a T1 signaling link and up to 24 ISDN-PRI Trunk Group memb ers. The DS1 provides up to 24 ports. nA TN464C/D/E DS1 circuit pack is required for assignment of an E1 signaling link and up to 31 ISDN-PR I T ru nk G ro u p me m bers. The DS1 provides up to 31 ports. nA TN768 or TN780 Tone Clock circuit pack is required to provide synchronization for the DS1 circuit pack. nA TN765 Processor Interface circuit pack is required for use with all DS1 circuit packs. For G3r, the following is required: nA TN464C/D/E DS1 circuit pack for assignment of a T1 signaling link and up to 24 ISDN-PRI trunk group members. The DS1 provides up to 24 ports. nFor G3iV2 only, a TN464C/D/E DS1 circuit pack for assignment of an E1 signaling link and up to 31 ISDN-PR I trunk group members. The DS1 provides up to 31 ports. nA TN767 is not needed, although it can be used for an a d ditional B-c hannel in a signaling group as long as there is a TN464C/D/E in that group to carry the D-channel. nA TN765 is not needed. Display-equipped voice terminals are required for the display of ISDN-PRI Call Identification Display information. One processor interface link is required per ISDN-PRI for G3i, and G3vs/G3s only. If CPN/BN to Host Call Identification is desired, a computer, such as a 3B2, is required for use as the ISDN Gateway. ISDN-PRI software is required.
Feature Descriptions 3-818Issue 3 March 1996 Hardware and software requirements for countries other than the United States of America are detailed in the Application Notes.
Inter-PBX Attendant Calls Issue 3 March 1996 3-819 Inter-PBX Attendant Calls Feature Availability This feature is available with all Generic 3 releases. Description Allows attendant positions for more than one branch location to be concentrate d at one central, or main, location. Incoming trunk calls to the branch location, as well as attendant-seeking voice terminal calls, are routed over tie trunks to the attendants at the main location. Inter-PBX Attendant Calls are incoming tie trunk calls from the branch location to the main location with the attendant group as the destination. If no attendant in the attendant group is available, these calls are queued. When an attendant becomes available, the call is routed to that attendant for handling. Calls can b e extended the same as if the call were an incoming call to the main location. When the attendant releases the call, the tie trunk associated with the call is tied up with the call until the call is dropped. A DEFI NI TY syst em Generic 3 can b e a branch or a main location for this feature. A branch location can have local attendants. These local attendants can be accessed by the Individual Attendant Access feature. The attendants at the main location are the local attendants for the main location and also the attendant for the Inter-PBX Attendant Calls. Considerations With Inter-PBX Attendant Calls, the numb er of attendants required at each branch location is reduced. Also, users at each branch location can use the main location to access each of the other branch locations. The Inter-PBX Attendant Calls feature can also be used within an ETN, where, for example, the attendant group for the network could be located at the main switch and serve other tandem switches connected by tie trunks. Interactions The following features interact with the Inter-PBX Attendant Calls feature. nAttendant Control of Trunk Group Access If Inter-PBX Attendant Calls is enabled, and a call at a branch location attempts to access a controlled trunk group, the call is routed to the local attendant at the branch location, if there is one. If there is no local attendant, the call is routed to the attendant group at the main location.
Feature Descriptions 3-820Issue 3 March 1996 nAttendant Display and DCS Attendant Display In a DCS environment, an incoming Inter-PBX Attendant Call from a branch location is displayed at the attendant console the same as a local call. In a non-DCS environment, an incoming Inter-PBX Attendant Call is displayed at the attendant console as an incoming tie trunk call. nAttendant Recall If an attendant at the main location holds an Inter-PBX Attendant Call, the calling parties at the branch location cannot recall the attendant. nCall Coverage At a branch location with Inter-PBX Attendant Calls enabled, a call redirected to a coverage path with the attendant group as a coverage point skips that coverage point. It goes to the next coverage point at the local switch, if administered, or continues to ring at the extension that is the previous coverage point. If the attendant group ‘‘0’’ is the only coverage point, it continues to ring at the principal’s extension. nCentralized Attendant Service (CAS) CAS and Inter-PBX attendant calling cannot b e enable at the same time. nDial Access to Attendant Dial Access to Attendant should be administered to the same digit on both the IAS main switch and the IAS b ranch switch. This is done via the dial platform. On the branch switch, the later PBX attendant access code (“Console Parameters” form) should be administered to match the main PBXs attendant group dial access code. nNight Service The Inter-PBX Attendant Calls feature is deactivated when the branch location is p ut into night service, and reactivated when the branch location is taken out of night service. Administration Inter-PBX Attendant Calls is administered by the System Manager. The following items require administration: nBranch location access to Inter-PBX Attendant Calls nInter-PBX Attendant Calls Trunk Grou p nInter-PBX Attendant Access Code Hardware and Software Requirements Requires a tie trunk g roup between the branch and main locations. No ad d itional software is required.
Intercept Treatment Issue 3 March 1996 3-821 Intercept Treatment Feature Availability Intercept Treatment is available with all Generic 3 releases. Description Provides an intercept tone or a recorded announcement or routes the call to an attendant for assistance when calls cannot be complete d or when use of a feature is denied. nIntercept Treatment — Tone Provides a siren-type tone to internal calls that cannot be comp leted as dialed. Intercept Tone is provided to voice terminals when users lift the handset and d o not dial within 10 seconds, pause longer than 10 seconds b etween digits during the dialing process, or remain connected to Loudspeaker Paging for longer than an administered interval. When a single-line voice terminal user receives Interc ept Tone for 30 seconds and does not hang up, then 10 seconds after the Intercept Tone stops, the user receives dial tone for a new call origination. Also, when the user does not hang up after all other p arties on the c all have hung up, then 10 seconds after all other parties disconnect, the user receives dial tone for a new call origination. When multiap pearance voice terminal users receive Interc ept Tone for 30 seconds and do not hang up, the call appearance returns to i dle. If the multiappearance user is the last party left on a call, the call appearance immediately returns to idle. If a voice terminal extension is assigned a COS with Off-hook Alert, and the user of that voice terminal receives Intercept Tone for a specified period of time and does not hang up, an emergency call is placed to the attendant. On DID calls, if the MFC (Multifrequency Compelled Signaling) Intercept Treatment is set to provide a tone, this signal is sent to the CO to indicate that the called number is invalid. (For further d etails, see the R2-MFC Signalin g feature description later in this chapter.) On DOD calls using MFC signaling, if the PBX receives the MFC Interc ept Tone from the CO indicating the number called is invalid, the PBX sends an intercept signal to the calling station.
Feature Descriptions 3-822Issue 3 March 1996 nIntercept Treatment — Recorded Announcement Provides a recorded announcement to DID and incoming Private Network Access calls that cannot be completed as dialed or that are transferred to incomp lete or restricted stations. The System Manager selects and records the message. Toll charges do not apply to DID and Private Network Access calls routed to Recorded Announcement. nIntercept Treatment — Attendant Allows attendants to provide information and assistance to callers on all DID or incoming Private Network Access calls that cannot be completed as dialed or that are transferred to incomplete or restricted stations. Normal toll charges apply to these calls. nIntercept Treatment — Station Allows a specific voice terminal to receive certain calls that cannot b e completed because of a controlled restriction (see Controlled Restrictions feature) or because the called party has activated Do Not Disturb . The controlled restrictions which can administered to send calls to station intercept are Outward, Termination, and Station-to-Station. The calling party hears audible ringing while the call is being routed to the voice terminal assigned for Intercept Treatment. The calling party receives no indication that the call is receiving Interc ept Treatment. Considerations The Intercept Tone lets a user know when a call c annot b e completed as dialed. The user can then hang up or try the call again. When DID and Private Network Access calls cannot be complete d as dialed, a record ed announcement can be provided or, for more p ersonal service, the calls can be routed to an attendant or voice terminal user. Recorded announcements can be used with the system. None, some, or all of these announcements can be used for Intercept Treatment. Only one p erson can be connected to an announcement at any given time. The caller is always connected to the beginning of the announcement. Interactions nR2-MFC For DID MF calls, whether the corresponding B.x signal or the Intercept Tone should be sent to the CO is administrable. The default is to send the standard DID/TIE/ISDN Intercept Treatment d esc rib e d in this section. If the option to send the B.x signal is set, then:
Intercept Treatment Issue 3 March 1996 3-823 — For Group II type calls, the B.x signal for the intercept is sent to the CO. — For non-Group II type calls, if the CO dials an invalid number, the trunk is locked (regard less of this option). If the CO dials the number which is valid but not assigned, the Intercept Treatment Tone is sent to the CO. nRecorded Announcement Attendant Intercept and Recorded Announcement Intercept (both optional) cannot be used together. DID calls and Private Network calls cannot be assigned Intercept Treatment — Tone. Administration The Intercept Tone is standard and requires no administration. However, administration is required to d etermine whether DID and Private Network Access calls are routed to the attendant or to an announcement. Administration is required to determine whether calls sent to interc ept because of controlled restrictions are routed to intercept tone, a voice terminal, an attendant, or an announcement. If an announcement is to be used, the announcement must be administered. Intervals are administrable with the “ System Parameters” form. Hardware and Software Requirements Requires announcement equipment and one port on an Analog Line circuit pack for each announcement for each external analog announcement device or an aux trunk port for each external auxtrk device. The Multiple Integrated Announcements allows equi p ping additional TN750C circuit packs. See the Record ed Announcement feature for more details. Wit h DE FI NITY system Generic 3i, a TN750 Announcement circ uit pack can be used to provide up to 128 (for G3i), or u p to 256 (for G3r) different announcements. The announcements can be recorded directly onto the TN750 circuit pack. No announcement equipment is required when this circuit pack is used. No a d ditional software is required.
Feature Descriptions 3-824Issue 3 March 1996 Intercom — Automatic Feature Availability This feature is available with all Generic 3 releases. Description Provides a talking path between two voice terminal users. Calling users press the Automatic Intercom b utton and lift the handset, or vice versa. The called user receives a unique intercom alerting signal, and the status lamp associated with the Dial or Automatic Interc om button, if provided, flashes. Considerations With the Intercom—Automatic feature, users who frequently call each other can do so by pressing one button instead of dialing an extension numb er. Single-line voice terminal users can receive Automatic Intercom calls, but cannot originate them. A comb ination of the Intercom—Automatic and Intercom—Dial features c an be used between terminals so that Intercom—Automatic ap plies in one direction and Interc om—Dial ap plies in the other. Two terminals with Intercom—Automatic to and from each other, or terminals with combined Intercom—Automatic and Intercom—Dial to each other, must be in the same Interc om group. Interactions The following features interact with the Intercom—Automatic feature. nCall Coverage Intercom calls are redirected only if the caller activates Go to Cover. nData Privacy and Data Restriction 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. nIntercom—Dial This feature must be provided. Users assigned an Automatic Intercom button must be a member of the same Dial Interc om g roup as the destination extension number.
Intercom — Automatic Issue 3 March 1996 3-825 nSingle-Digit Dialing and Mixed Station Numbering Prefixed extensions greater than five digits (including the prefix) in length cannot be assigned to intercom lists. nClass of Restrictions (COR) COR may be administered su ch that station A cannot d ial Station B. The user at Station A would receive intercept tone. However, Station A can be administered such that it has Intercom—Automatic capability to Station B. Thus A could call B. The System Manager has control of station restrictions and which stations are in the same Intercom group. Administration Intercom—Automatic is assigned on a per-voice terminal b asis by the system administrator. Before Intercom—Automatic can be assigned, the associated Intercom group must be established. Each Intercom group requires the following administration: nIntercom group number nLength of dial c o de nExtension number within the group nDial c o des to access Intercom group members Once the Intercom group is established, Automatic Intercom buttons can be assigned to memb ers of the group. The following items must be a dministered for each button. nIntercom group number to be accessed nDial c o de assigned to group member to be accessed Hardware and Software Requirements No a d ditional hardware or software is required. Voice terminals equipped with a buttons and a status lamp are useful, but not required.
Feature Descriptions 3-826Issue 3 March 1996 Intercom—Dial Feature Availability This feature is available with all Generic 3 releases. Description Allows multiappearance voice terminal users to gain rapid access to selected other voice terminal users within an administered group. Calling voice terminal users lift the handset, press the Dial Intercom button, and dial the 1- or 2-digit code assigned to the desired party. The called user receives alerting tone, and the status lamp associated with the Intercom button, if provided, flashes. Considerations With the Intercom—Dial feature, a group of users who frequently call each other can do so b y p ressing a Dial Intercom b utton and dialing a one- or two-digit code instead of dialing an extension number. The maximum number of intercom groups that can be established varies according to the system. See Ap pendix A, System Parameters. Single-line voice terminals can receive Intercom—Dial c alls, b ut cannot originate them. A comb ination of Interc om—Dial and Intercom—Intercom can be used between terminals so that Intercom—Dial applies in one direction and Intercom—Intercom a p plies in the other. A Interc om—Dial user can place an intercom call to all members in the group, including Intercom—Automatic memb ers. Two terminals with Intercom—Dial to and from each other, or two terminals with combined Intercom—Dial and Intercom—Automatic to and from each other, must be in the same Intercom group. Interactions The following features interact with the Intercom—Dial feature. nIntercom—Automatic Users assigned this feature must be a member of a Dial Interc om group.
