    Facility restriction levels and
    traveling class marks
    Facility Restriction Levels (FRL) and Travelling Class Marks (TCM) allow 
    certain calls to specific users, and deny the same calls to other users. For example, 
    you can give certain users access to central office (CO) trunks to other corporate 
    locations, and you can restrict other users to less expensive, private-network lines. 
    Detailed Description
    FRL
    The switch compares the FRL of the outgoing phone to the FRL of either the 
    terminating trunk group or, for AAR and ARS, the routing preference specified on 
    the Routing Pattern Table. If the FRL of the originator is equal to or greater than 
    the terminating or route pattern FRL, the call continues. Otherwise, the call is 
    blocked. 
    TCM
    If an intertandem tie-trunk group is used for a call, then a TCM is outpulsed as the 
    last digit. If the intertandem tie-trunk FRL is equal to or greater than the 
    terminating FRL, the call continues. If the originating FRL is less than the 
    terminating FRL, the TCM is compared with the tie-trunk’s FRL. If the TCM is 
    greater than or equal to the FRL, the call continues.
    Call-originating facilities
    Any of the following can originate an AAR or ARS call. Each is assigned an FRL 
    via an associated Class of Restriction (COR).
    nattendant
    ndata terminal capable of keyboard dialing
    nincoming tie-trunk group from a subtending location
    nincoming intertandem tie-trunk group (at a tandem switch)
    nincoming access tie-trunk group (links a remote main switch to a tandem 
    switch)
    nphone
    nremote access user
    Phones and all incoming tie-trunk groups use the FRL of their COR. On 
    attendant-extended calls, the attendant-group FRL is used. If Individual Attendant

    20
    Access assigned, the individual attendant’s COR FRL is used. Data terminals use 
    the FRL of the COR assigned to the associated data module.
    A remote access call uses the FRL of the COR assigned to the dialed barrier code. 
    If a barrier code is not required on remote access calls, there is no FRL
    Call terminating facilities
    Any of the following trunk types can serve as the termination point for an AAR or 
    ARS call:
    nTie trunk — excluding Release Link Trunks (RLT), but including Common 
    Control Switching Arrangement (CCSA) and Enhanced Private Switched 
    Communications Services (EPSCS) access trunks
    nWide Area Telecommunications Service (WATS)
    nCentral Office (CO)
    nForeign exchange (FX)
    nIntegrated Services Digital Network - Primary Rate Interface (ISDN-PRI)
    Each of these outgoing trunk groups has an assigned COR that contains an FRL. 
    However, this FRL is never used in an AAR or ARS call. A terminating-side FRL 
    for AAR/ARS calls is assigned in the route pattern, not to the outgoing trunk 
    group.
    FRL guidelines
    You assign the FRL to the trunk group within the route pattern. You can use the 
    same trunk group in more than one route pattern, and the same trunk group can 
    have a different FRL in a different pattern. You can assign the same FRL to more 
    than one trunk group.
    Be consistent in FRL assignments. For ease of assignments, always use FRL 0 or 
    1 for a trunk group that everyone can access. If you use a range of 0–5 in one 
    pattern, use the same range in another pattern if all users can access the 
    first-choice route.
    Assign a COR with an FRL of 0 to a group of users to restrict them from making 
    outgoing calls. Use any other number for the FRL on your first choice route 
    pattern. This denies access to any trunk group for the users, because all 
    trunk-group FRLs are greater than 0.
    You assign FRLs for remote access users through the remote-access barrier codes. 
    You can assign up to 10 barrier codes, each with its own COR and FRL. The 
    simplest way to assign these FRLs is to duplicate the on-premises FRLs, then 
    relate the appropriate barrier code to users who need remote access.

    Generalized route selection
    Generalized Route Selection (GRS) is built into Automatic Alternate Routing 
    (AAR) and Automatic Route Selection (ARS). This switch uses GRS to look at 
    various route patterns and preferences and decide which preference is most 
    appropriate at the time. With GRS, voice and data calls can be sent along separate 
    routes or be integrated on the same trunk group. If the type of transmission is 
    incompatible with the endpoint (for example, a digital data call is sent to an 
    analog phone), GRS provides a conversion resource such as a modem from a 
    modem pool to complete the call.

    20
    Detailed description
    GRS recognizes one or more Bearer Capability Class (BCC) for each trunk group 
    preference in the route pattern. BCC defines the type of information being sent as 
    voice or data. The switch checks the BCC for all trunk groups to see if the route 
    selected and type of call are compatible. The BCC is assigned to the route 
    preference on the Route Pattern screen.
    GRS chooses a preference with BCC set to yes in this order: BCC 2, BCC 1, BCC 
    3, BCC 4. 
    When an exact match is not found in any route-pattern preference, calls with 
    originating BCCs listed are treated as follows:
    nBCC of 0 (such as voice or analog modem)
    GRS routes a BCC 0-originated call with no match. This allows voice 
    transfer to data when making a data call. 
    Since BCC 0 (voice) has no Information Transfer Capability (ITC), the 
    switch selects an ITC from the route pattern when a BCC 0 call is routed as 
    a data call. Ta b l e  5 0
     shows how the ITC codepoint in the Bearer Capability 
    IE is determined.
    nBCC 2
    If there is no preference with BCC 2 yes, GRS chooses a preference with 
    BCC 0 yes. If BCC 0 yes does not exist, the call is blocked.
    nBCC 1, 3, or 4
    BCC 4 (DCP/DMI Mode 0), BCC 1 (Mode 1), and BCC 3 (Mode 3) calls 
    requires an exact match in order for the call to complete. ITCs must also 
    match.

    Example
    Assume a route pattern is set up with BCC 0 and BCC 2 set to yes in preference 1, 
    and BCC 1, BCC 3, and BCC 4 set to yes in preference 2.
    A voice or Mode 2 data call accessing this pattern uses preference 1. A Mode 1, 
    Mode 3, or Mode 0 data call uses preference 2, regardless of what trunks are 
    available in the first preference.
    Data modules and GRS
    For all endpoints, the switch automatically determines its current operating mode 
    when a data module begins operations. The default is Mode 2.
    Because call origination from a data module determines the mode used on the call, 
    you should press the Originate/Disconnect button if you change data options. This 
    way, the right mode is assigned to the next call.

    Route Pattern’’ on page 877 for information on how to set up route 
    patterns.
    Group paging
    Group paging allows users to make an announcement over a group of digital 
    speakerphones.
    nYou can create up to 32 paging groups on one DEFINITY ECS.
    nEach group can have up to 32 extensions in it.
    nIt’s OK to assign the same extension to different groups.
    Brief description
    You, the switch administrator, create paging groups and assign extensions as 
    members to the appropriate groups. Each group is assigned its own identifying 
    extension, and users page the group by dialing this extension. When a user dials 
    the group’s extension, the switch activates the speakers on all the phones in the 
    group. Speakerphone paging is one-way communication: group members hear the 
    person placing the page but cannot respond directly.
    Restrictions
    Pages aren’t always heard on every phone in a group. An extension does not 
    transmit a group page if it has an active or ringing call or if it is off-hook. 
    Listeners may drop a page by disconnecting. Refer to ‘‘
    Interactions’’ on page 
    1355 for features that block group pages.

    Controlling access to paging groups
    Each paging group is assigned a class of restriction, so you can provide or deny 
    access to different classes of users by setting calling permissions appropriately. 
    Note that you can administer classes of restriction so remote callers can make 
    speakerphone pages. If you don’t want to allow remote users to page, you may 
    want to set calling permissions (on the Class of Restriction screen) for VDNs and 
    trunk groups so that neither can initiate pages.
    Interactions
    nAttendant Intrusion
    Attendants cannot intrude on group pages. If the attendant tries to intrude 
    on the paging originator, the intrusion attempt succeeds. However, all 
    group page members are able to hear both the paging originator and the 
    attendant.
    nAuto Exclusion and Manual Exclusion
    Bridged appearances are not allowed on the page. Therefore, the Auto 
    Exclusion and Manual Exclusion features are disabled. Auto Exclusion is 
    not activated because there are no bridged appearances to alert when the 
    page terminates. 
    nAuto Hold
    Auto Hold does not put a group page on hold.The page is dropped and the 
    incoming call is answered.
    nAutomatic Callback
    Automatic Callback is disabled when calling an active page group. 
    nBridging
    Bridging is disabled on this feature. A bridged appearance of a group 
    member does not receive any indication of a call when the page arrives. 
    The bridged appearance cannot bridge onto the page. 
    nCall Coverage
    Pages do not follow group members’ coverage paths. A page group cannot 
    be a coverage point.
    nCall Park
    Group members who receive a page cannot park the call.
    nCall Pickup/Direct Call Pickup
    Other extensions cannot pick up a group page.
