    Incoming Rotary Timeout (sec)
    Call setup at central offices that still use older switching equipment, such as 
    step-by-step technology, is considerably longer then at central offices with more 
    modern switches. If you’re receiving digits with incoming calls from a central 
    office that uses less efficient switching technology, your switch needs to allow 
    more time to ensure it receives all the incoming digits. When the Incoming Dial 
    Type field is rotary, use this field to set the maximum time your switch will wait to 
    receive all incoming digits from the far-end switch.
    Outgoing Dial Type
    This field sets the method used to transmit digits for an outgoing call. Usually, you 
    should match what your central office provides. Refer to ‘‘
    Types of address 
    transmission’’ on page 1584 for more information. This field appears for Access, 
    APLT, CO, DIOD, DMI-BOS, FX, RLT, and WATS trunk groups. It also appears 
    for Tie trunk groups when the Trunk Signaling Type field is blank, 
    cont, or dis.
    DIOD trunks support pulsed and continuous E&M signaling in Brazil and 
    discontinuous E&M signaling in Hungary. Refer to DEFINITY ECS Application 
    Notes for Type Approval for more information.
    Valid entries Usage
    5
     to 99If the system is connected to a step-by-step central office, or 
    any CO using older switching technology, enter at least 
    18 
    seconds; if not, enter at least 
    5 seconds.
    Valid entries Usage
    tone
     Enter tone to use Dual Tone Multifrequency (DTMF) 
    addressing, also known as “touch tone” in the U.S. Entering 
    tone actually allows the trunk group to support both DTMF 
    and rotary signals.
    For pulsed and continuous E&M signaling in Brazil and for 
    discontinuous E&M signaling in Hungary, use 
    tone or mf.
    rotaryEnter rotary if you only want to allow the dial pulse addressing 
    method used by non-touch tone phones. If you have a full touch 
    tone system internally and a connection to a central office that 
    only supports rotary dialing, for example, it would be 
    appropriate to enter 
    rotary.

    Cut-Through
    This field appears when the Outgoing Dial Type field is either 
    rotary or tone.
    !SECURITY ALERT:
    Entering 
    y in this field will reduce your ability to prevent toll fraud.
    mfEnter mf if the Trunk Signaling Type field is blank. The 
    Multifrequency Signaling field must be enabled on the 
    System-Parameters Customer-Options screen in order for you 
    to enter 
    mf here.
    You may not enter mf if the Used for DCS field (Field 
    descriptions for page 2) is 
    y.
    For pulsed and continuous E&M signaling in Brazil and for 
    discontinuous E&M signaling in Hungary, use 
    tone or mf.
    automaticEnter automatic for tie trunks if the Trunk Signaling Type 
    field is blank. This provides “cut-through” operation to 
    outgoing callers who dial a trunk access code, connecting them 
    directly to central office dial tone and bypassing any toll 
    restrictions administered on your switch.
    r1mfCAMA trunk groups use r1mf. It is the only outgoing dial type 
    allowed on CAMA trunk groups.
    Valid entries Usage
    y
    Enter y to allow users to get dial tone directly from the central 
    office. Outgoing calls over this trunk group will bypass 
    AAR/ARS (if you’re using it) and any of your administered 
    restrictions (such as COR or FRL).
    n Enter n and the user will receive switch dial tone. Instead of 
    digits being sent to the central office, they will be collected and 
    checked against administered restrictions. If no restrictions 
    apply, the digits are sent to the central office.

    Incoming Dial Type
    Indicates the type of pulses required on an incoming trunk group. Usually, you 
    should match what your central office provides. Refer to ‘‘
    Types of address 
    transmission’’ on page 1584 for more information. This field appears for Access, 
    APLT, DID, DIOD, DMI-BOS, FX, RLT, Tandem, and WATS trunk groups. It 
    also appears for Tie trunk groups when the Trunk Signaling Type field is blank, 
    cont, or dis.
    NOTE:
    The value in this field affects the appearance of the Incoming Partial Dial 
    (sec) field on the Administrable Timer Page.
    Wink Timer (msec)
    This field allows you to reduce the risk of glare by controlling part of call setup. 
    Requirements for the United States domestic network specify that the wink signal 
    for wink-start trunks must begin within 5 seconds after a trunk is seized. For 
    trunks with a delay-dial start, the wink must not last longer than 5 seconds. While 
    some circuit packs are hard-coded to allow the full 5 seconds in both cases, other 
    circuit packs allow you reduce the allowed start time and duration, thus reducing 
    the window in which glare could occur.
    Valid entries Usage
    tone
     Enter tone to use Dual Tone Multifrequency (DTMF) 
    addressing, also known as “touch tone” in the U.S. Entering 
    tone actually allows the trunk group to support both DTMF 
    and rotary signals. Also, if you’re using the Inband ANI 
    feature, enter 
    tone.
    For pulsed and continuous E&M signaling in Brazil and for 
    discontinuous E&M signaling in Hungary, use 
    tone.
    rotaryEnter rotary if you only want to allow the dial pulse addressing 
    method used by non-touch tone phones. Though the tone entry 
    supports rotary dialing as well, it’s inefficient to reserve touch 
    tone registers for calls that don’t use DTMF.
    mfEnter mf if the Trunk Signaling Type field is blank. The 
    Multifrequency Signaling field must be enabled on the 
    System-Parameters Customer-Options screen in order for you 
    to enter 
    mf here.
    You may not enter 
    mf if the Used for DCS field (Field 
    descriptions for page 2) is 
    y.
    For pulsed and continuous E&M signaling in Brazil and for 
    discontinuous E&M signaling in Hungary, use 
    mf.

    Unlike other fields on this screen, the Wink Timer field therefore controls 2 
    different variables. What your entry does depends on the outgoing value in the 
    Trunk Type (in/out) field.
    .
    This field appears when the “out” side of the entry in the Trunk Type (in/out) field 
    is 
    …/wink or …/delay and the Group Type is tie, access, aplt, dmi-bos, rlt, or 
    tandem. The setting in this field only affects trunks administered to ports on 
    TN760C (vintage 4 or later), TN767, TN464C (or later), and TN2242 circuit 
    packs. If the trunk group also contains trunks assigned to ports on other types of 
    circuit packs, those trunks are unaffected.
    Trunk Termination
    This field adjusts the impedance of the trunk group for optimal transmission 
    quality. Check with your service provider if you’re not sure of the distance to your 
    central office.

    If you do, remember that your switch’s timing must be 
    compatible with the timing on the far-end switch.
    Valid entries Usage
    600ohm
    Enter 600ohm when the distance to the central office or the 
    switch at the other end of the trunk is less than 3,000 feet.
    rc Enter rc when the distance to the central office or the switch at 
    the other end of the trunk is more than 3,000 feet.

    Disconnect Timing (msec)
    This field specifies the minimum time in milliseconds that the central office or 
    far-end switch requires to recognize that your switch has disconnected from a call. 
    This timer does not affect ports on a circuit pack that uses the administrable 
    Incoming Disconnect and Outgoing Disconnect timers; in fact, settings on those 
    two timers override this field.
    End-to-End Signaling
    Auxiliary equipment such as paging equipment and music sources may be 
    connected to DEFINITY ECS by auxiliary trunks. The switch may send DTMF 
    signals (touch tones) to these devices. This field, which appears for CPE 
    (customer-provided equipment) trunk groups, sets the duration of these tones.
    NOTE:
    For trunks that do not receive real answer supervision, a “connect” Event 
    report is sent when the Answer Supervision Timeout occurs.
    Analog Gain
    Use this field to reduce the strength of incoming signals on TN2199 ports if users 
    regularly experience echo, distortion, or unpleasantly loud volume. Experiment to 
    find the best setting for your situation. This field appears if the Country field is 
    15 
    and the Trunk Type (in/out) field is 
    2-wire-ac, 2-wire-dc, or 3-wire.
    Valid entries Usage

     to 2550 ms 
    in increments of 
    10The default of 500 is an industry standard and you shouldn’t 
    change it. If you set this field too high, your switch won’t 
    disconnect sometimes when it should; too low, and it will 
    disconnect when it shouldn’t.
    Valid entries Usage
    60
     to 360 ms in

    a
      Reduces the incoming signal by -3dB. 
    b  Reduces the incoming signal by -6dB.
    c  Reduces the incoming signal by -8dB. 
    none  No reduction. Don’t change this setting unless the trunk 
    group’s sound quality is unacceptable.

    Digit Treatment
    Use this field to modify an incoming digit string (as on DID and tie trunks, for 
    example) by adding or deleting digits. You’ll need to do this if the number of 
    digits you receive doesn’t match your dial plan.
    If you enter absorption or insertion, then you must enter a value in the Digits field.
    NOTE:
    In a DCS network, DCS features that use the remote-tgs button (on phones 
    at a remote switch) do not work when the incoming trunk group at your 
    switch deletes or inserts digits on incoming calls. The remote-tgs button on a 
    remote switch, for example, tries to dial a TAC on your switch. If your 
    switch adds or deletes digits, it defeats this operation. If you need to 
    manipulate digits in a DCS network (for example, to insert an AAR feature 
    access code), do it on the outgoing side based on the routing pattern.
    Digits
    This field is used with the Digit Treatment field, and its meaning depends on the 
    entry in that field. If the Digit Treatment field is 
    absorption, this field specifies 
    how many digits are deleted. If the Digit Treatment field is 
    insertion, this field 
    identifies the specific digits that are added.
    Valid entries Usage
    blank The incoming digit string is not changed.
    absorptionDeletes digits, starting at the beginning of the string.
    insertionAdds digits, starting at the beginning of the string.
    Valid entries Usage
     1 to 5 Enter the number of digits to be deleted (absorbed).
    Up to 4 digits, 
    including * and 
    #Enter the actual digits to be added (inserted).
    blank This field can be blank only if the Digit Treatment field is 
    blank.

    Expected Digits
    NOTE:
    Set this field to blank if the Digit Treatment field is set to insert and 
    the Digits field contains a feature access code (for example, AAR or 
    ARS) followed by digits. In this case, the number of digits expected 
    are set on the AAR and ARS Digit Analysis Table and AAR and ARS 
    Digit Conversion Table.
    Auto Guard
    This field controls ports only on TN438B, TN465B, and TN2147 circuit packs. 
    TN438B ports have hardware support for detecting a defective trunk. TN465B 
    and TN2147 ports consider a trunk defective if no dial tone is detected on an 
    outgoing call, and the Outpulse Without Tone field is 
    n on the Feature-Related 
    System Parameters screen. 
    Call Still Held
    This field is used when the receiving switch initiates the disconnection of 
    incoming calls. It effectively extends the Incoming Glare Guard timer by 140 
    seconds. This field affects only TN438B, TN465B, and TN2147 ports and is used 
    primarily when the Country Code field is 
    2.
    Valid entries Usage

     to 18Enter the number of digits that the far-end switch sends for an 
    incoming connection. If your switch is absorbing digits on this 
    trunk group, the entry in this field must be larger than the entry 
    in the Digits field.
    blank If you leave this field blank, you cannot administer digit 
    absorption.
    Valid entries Usage
    y/n 
    Enter y to prevent repeated seizures of a defective trunk. The 
    switch will do a maintenance busy-out on these trunks.
    Valid entries Usage
    y/n 
    Enter y to prevent glare by delaying an outgoing seizure of a 
    trunk for at least 140 seconds after it is released from an 
    incoming call.

    Sig Bit Inversion
    When transmission facilities use bit-oriented signaling (such as CAS), 2 bits are 
    used to transmit seizure and release signals for calls. Called the A-bit and the 
    B-bit, their meaning can vary. For example, in the A-bit a “1” might mean 
    on-hook and a “0” might mean off-hook. The entry in the Country Protocol field 
    on the DS1 Circuit Pack screen sets the default meaning of these bits.
    For trunk ports on TN2242 and TN464B and later circuit packs, this field allows 
    you to invert the A- and B-bits as necessary so that the far-end switch can 
    understand your switch’s seizure and release signals. If the far-end switch, such as 
    a central office, on this trunk group interprets the A- and B-bits differently from 
    the default, you may need to invert one or both bits — to change “1” to “0” and 
    vice-versa in the A-bit, for example. 
    Analog Loss Group
    This field determines which administered 2-party row in the loss plan applies to 
    this trunk group if the call is carried over an analog signaling port in the trunk 
    group. 
    Digital Loss Group
    This field determines which administered 2-party row in the loss plan applies to 
    this trunk group if the call is carried over a digital signaling port in the trunk 
    group.
