    Definitions of Group I, II, A, and B signals
    Group I signals
    Group I signals are a set of forward signals generated by the originating switch.
    ani-avail
    Used in Hungary. If this signal is defined and ANI is requested on outgoing 
    R2-MFC calls, ANI is sent to the CO before ANI caller digits are sent. This signal 
    is sent after the ANI caller category signal.
    ani-not-avail
    Used on DOD calls in Brazil and Columbia. The switch sends this signal to the 
    CO when it receives an ANI request and the caller’s number is not available. 
    digits 1 to 10
    The signals from group I.1 to I.10 are reserved for address digits 0 to 9.
    drop
    When this signal is received from the CO, the switch starts the disconnect 
    sequence and drops the call.
    end-of-ani
    This signal is used on DOD and DID calls. The switch sends this signal to indicate 
    the end-of-ANI digits when ANI digits are sent to the CO.

    17
    end-of-dial
    This signal is used when open numbering is used on DID calls. The CO sends this 
    signal to indicate the end-of-dial digits and the switch responds with a request for 
    a group II signal.
    end-of-digits
    This signal is sent by the origination switch that makes outgoing calls, sends 
    digits, and receives a next-digit group A signal from the destination switch when 
    there are no more digits to be sent.
    This signal is also sent when the switch does not have end-of-ani assigned, makes 
    an outgoing call, sends ANI, and receives a call-info-ani group A signal from the 
    destination switch when there are no more ANI digits to be sent. 
    If both end-of-digits and end-of-ani are assigned, the switch uses end-of-ani after 
    it sends the last ANI digit and end-of-digits after sending the last called-number 
    digit.
    ignored
    If this signal is received from the CO, the switch sends a corresponding signal 
    (A.1, and so on) but no action is taken in the response and it is not counted as a 
    digit. In Belgium, this signal is not acknowledged.
    maint-call
    The CO sends a signal to indicate that a call is a maintenance call and the switch 
    prepares the special maintenance call sequences for the CO. This signal may be 
    used on DID calls in Saudi Arabia.
    send-congestion
    When the switch receives this signal from the CO on a DID call, it returns a 
    congestion signal (group A), in compel (not pulse) mode, to the CO. 
    Group II signals
    Group II signals are a more elaborate set of forward signals generated by the 
    originating switch.
    attendant
    If the switch receives this signal on DID calls, the call terminates at an attendant 
    regardless of the extension dialed. On DOD calls, this signal is sent to the CO if 
    the CO requests calling-category information and the originating extension is an 
    attendant. This signal is used on both DID and DOD calls.

    17
    busy-rt-attd
    If the switch receives this signal on DID calls, the call terminates at an attendant if 
    the called extension is busy or at the called extension if it is not busy. This signal 
    is used on DID calls.
    data-call
    This signal is treated the same as the data-verify signal except that it does not 
    require a terminating extension to be a data extension.
    data-verify
    If the switch receives this signal on DID calls and the terminating extension is not 
    a data extension, it sends intercept treatment. On DOD calls, this signal is sent to 
    the CO if the CO requests calling-category information and the originating 
    extension is a data extension. This signal is used on both DID and DOD calls.
    drop
    When this signal is received from the CO, the switch starts the disconnect 
    sequence and drops the call.
    maint-call
    The CO sends a signal to indicate that a call is a maintenance call and the switch 
    prepares the special maintenance call sequences for the CO.
    normal
    This signal indicates that the caller is a normal subscriber. If it is received on a 
    DID call, the call is terminated at the called extension. For an outgoing MF 
    signaling call that uses group II signaling, this signal is sent to the CO when the 
    CO requests calling-category information and the originating extension is a 
    station. This signal is used in both DID and DOD calls.
    send-intercept
    If the switch receives this signal from the CO on a DID call, it returns group B 
    intercept signal to the CO.
    toll-auto
    This signal is used in China. This signal indicates that a call is an automatic toll 
    call. When the call terminates at a busy station and a special busy signal is 
    defined, the busy signal is sent to the CO. You can define the special busy signal 
    by choosing the option toll-busy on the incoming group B signals.

    toll-operator
    This signal, used in China, is treated as a normal subscriber signal. See the normal 
    definition.
    Group A signals
    Group A signals are backward signals generated by the destination switch.
    send-ani
    The CO sends this signal to request calling-party category and sends additional 
    signals to request ANI digits. This signal is sent to the CO when DEFINITY ECS 
    requests ANI digits on DID calls. This signal is used on both DOD and DID calls.
    congestion
    The CO sends this signal to indicate that it is experiencing network congestion. 
    When the switch receives this signal on DOD calls, the switch drops the trunk and 
    plays reorder tone to the calling party. This signal is used on DOD calls.
    drop
    When this signal is sent, the receiving switch starts the disconnect sequence.
    end-of-dial
    This signal is sent to indicate the end of the address digit string. For MF group II 
    calls, this signal requests a group II signal and switches the sender over to the 
    group B signaling mode. This signal is used on both DID and DOD calls.
    intercept
    The CO sends this signal to indicate the call has been terminated to an invalid 
    destination. When the switch receives this signal on DOD calls, the switch drops 
    the trunk and plays intercept tone to the calling party. This signal is used on DOD 
    calls.
    resend-digit
    The switch sends this signal to adjust the outpulsing pointer so that the last digit 
    can be resent again. This signal is used on DOD calls.
    last-digit
    The switch sends this signal to adjust the outpulsing pointer so that the last 2 digits 
    can be resent. This signal is used on DOD calls.

    last-2-digits
    The switch sends this signal to adjust the outpulsing pointer so that the last 3 digits 
    can be resent. This signal is used on DOD calls.
    last-3-digits
    The switch sends this signal to adjust the outpulsing pointer so that the last 4 digits 
    can be resent. This signal is used on DOD calls.
    next-digit
    The switch sends this signal to request the next digit. This signal is used on both 
    DID and DOD calls.
    next-ani-digit
    The switch sends this signal to request the next ANI digit. This signal is used on 
    DID and DOD calls.
    restart
    The switch sends this signal to request the whole digit string again. This signal is 
    used on DOD calls.
    setup-sppath
    The CO sends this signal to the switch to set up a speech path. This signal is used 
    on DOD calls and on DID calls in Belgium.
    Group B signals
    Group B signals enhance group A signals for backward signaling from the 
    destination switch by providing the status of the called party. In addition, if the 
    originating switch uses group II signals, the destination switch answers with 
    group B signals. Group B signals are as follows:
    busy
    This signal is sent to indicate that the called party is busy. On DID calls, the signal 
    is sent to the CO if there is no coverage point to terminate the call. If the switch 
    receives this signal on DOD calls, it plays busy tone to the calling party and drops 
    the trunk.
    congestion
    This signal is sent to indicate that the system is congested and the call cannot be 
    terminated successfully. On DID calls, the signal is sent to the CO to indicate that 
    a resource is not available. On DOD calls, if the switch receives this signal, 
    reorder tone is played to the calling party and the trunk is dropped.

    17
    free
    This signal indicates that the called party is idle. On DID calls, the signal is sent to 
    the CO to indicate that the called party is idle and the call is terminated 
    successfully. If the switch receives this signal on DOD calls, it connects the trunk 
    to the calling party.
    intercept
    This signal indicates that the called party number is not in service or is not correct. 
    On DID calls, if intercept treatment is set to provide a tone, tone is sent to the CO 
    to indicate that the called number is not valid. If the switch receives the signal on 
    DOD calls, the switch plays intercept tone to the calling party and drops the trunk.
    mct
    This signal identifies the call as one that needs to be traced by the CO. DEFINITY 
    ECS then generates an MFC Call Trace Backward Signal  (administered on the 
    Multifrequency-Signaling-Related System-Parameters screen) during call setup 
    instead of the “free” signal. If the terminating station’s COR has this feature set to 
    y, the CO collects trace information before releasing the calling party.
    NOTE:
    If the station’s COR has MF Incoming Call Trace set to y and the “mct” 
    signal is not defined, then the “free” signal is sent.
    tariff-free
    This signal is sent when the trunk group provides an “800” service. DEFINITY 
    ECS generates an MFC tariff-free backward signal  (administered on the 
    System-Parameters Multifrequency-Signaling screen) during call setup instead of 
    the “free” signal, facilitating CO billing.
    NOTE:
    If the trunk is administered as a tariff-free trunk and the “tariff-free” signal is 
    not defined, then the “free” signal is sent.
    tie-free
    This signal is used only when an incoming call is received and defined and the 
    incoming facility is a tie trunk. Otherwise, the free signal is used.
    toll-busy
    This signal, used in China, is sent to indicate that the called party is busy if the call 
    is an automatic toll call.
