    							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.

    							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.

    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.

    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.
