    Managing trunks
    This chapter contains basic procedures for working with analog and digital trunks. 
    Specialized trunks such as Internet Protocol (IP) Solution, APLT, tandem, 
    release-link, and DMI-BOS trunks are not covered in this manual. For more 
    information, refer to DEFINITY ECS Administration for Network Connectivity. 
    This chapter also does not contain procedures for working with ISDN trunk 
    groups. Due to the complexity of ISDN technology and the potential 
    consequences of errors, ask your Lucent representative to assist you in planning, 
    installing, and administering ISDN trunks. For an introduction to ISDN service on 
    DEFINITY ECS, refer to ‘‘
    ISDN service’’ on page 1404. 
    Tips for working with trunk groups
    You’ll find detailed procedures for administering specific trunk groups elsewhere 
    in this chapter. However, there’s more to working with trunks than just 
    administering trunk groups.
    Following a process
    Trunking technology is complex. Following a process can prevent mistakes and 
    save you time. To set up new trunks and trunk groups, Lucent recommends 
    following the process below (some steps may not apply to your situation):
    1. Install the necessary circuit packs and perform any administration the 
    circuit pack requires.
    2. Connect the appropriate ports to your network service provider’s trunks.
    3. Administer a trunk group to control the operation of the trunks.
    4. Assign the ports you’re using to the trunk group.

    350 Tips for working with trunk groups 
    12
    5. For outgoing or 2-way trunks, administer Automatic Route Selection so 
    DEFINITY ECS knows which outgoing calls to route over this trunk 
    group.
    6. Test your new trunk group. Using the trunk access code, place a variety of 
    calls.
    This chapter provides instructions for steps 3 and 4 in this process.
    Working with your network service provider
    Depending on the type of trunk you want to add, the vendor may be your local 
    phone company, a long distance provider, or some other service provider. Key 
    settings on DEFINITY ECS must be identical to the same settings on the 
    provider’s equipment for your trunks to work. Clear, frequent communication 
    with your provider is essential — especially since some providers may use 
    different terms and acronyms than Lucent does!
    Once you decide that you want to add a new trunk, contact your vendor. The 
    vendor should confirm the type of signal you want and provide you with a circuit 
    identification number for the new trunk. Be sure to record any vendor-specific ID 
    numbers or specifications in case you ever have any problems with this trunk.
    Keeping records
    In addition to recording vendor-specific information such as ID numbers, you 
    should record the following information about every trunk group you have.
    The questions you need to answer The kind of information you need to get
    What type of trunk group is it? You need to know what kind of trunks these are 
    (central office (CO), foreign exchange (FX), 
    etc.) and whether they use any special services 
    (such as T1 digital service). You also need to 
    know what kind of signaling the group uses. For 
    example, you might have a CO trunk group with 
    ground-start signaling running on a robbed-bit 
    T1 service.

    Helpful tips for setting common fields
    The procedures in this section cover the specific fields you must administer when 
    you create each type of trunk group. Here are some tips for working with common 
    fields that are available for most trunk groups.
    nDial Access — Typing y in this field allows users to route calls through an 
    outgoing or two-way trunk group by dialing its trunk access code.
    !SECURITY ALERT:
    Calls dialed with a trunk access code over Wide Area 
    Telecommunications Service (WATS) trunks are not validated against 
    the ARS Digit Analysis Table, so users can dial anything they wish. 
    For security, you may want to leave the field set to 
    n unless you need 
    dial access to test the trunk group. Which phone numbers are associated 
    with each trunk group?For incoming or two-way trunk groups:
    nWhat number or numbers do outside callers 
    use to call into your switch over this group?
    nWhat’s the destination extension to which 
    this trunk group delivers calls? Does it 
    terminate at an attendant or a voice-mail 
    system?
    For outgoing trunk groups:
    nWhat extensions can call out over this trunk 
    group?
    Is the service from your network 
    service provider sending digits on 
    incoming calls?Direct Inward Dial and Direct Inward/Outward 
    Dial trunks send digits to your switch. Tie trunks 
    may send digits, depending on how they’re 
    administered. You need to know:
    nHow many digits is your service provider 
    sending?
    nAre you inserting any digits? What are they?
    nAre you absorbing any digits? How many?
    nWhat range of numbers has your service 
    provider assigned you?
    The questions you need to answer The kind of information you need to get

    12
    nOutgoing Display — Typing y in this field allows display phones to show 
    the name and group number of the trunk group used for an outgoing call. 
    This information may be useful to you when you’re trying to diagnose 
    trunking problems.
    nQueue Length — Don’t create a queue for two-way loop-start trunks, or 
    you may have a problem with glare (the interference that happens when a 
    two-way trunk is seized simultaneously at both ends).
    nTrunk Type — Use ground-start signaling for two-way trunks whenever 
    possible: ground-start signaling avoids glare and provides answer 
    supervision from the far end. Try to use loop-start signaling only for 
    one-way trunks.
    Related topics
    Refer to the DEFINITY ECS System Description for information on the types of 
    circuit packs available and their capacities.
    Refer to your switch’s installation manual for installation instructions for circuit 
    packs.
    Refer to ‘‘
    Routing outgoing calls’’ on page 185 for detailed information on 
    Automatic Route Selection.
    Adding a CO, FX, or WATS trunk 
    group
    Basic administration for Central Office (CO), Foreign Exchange (FX), and Wide 
    Area Telecommunication Service (WATS) trunk groups is identical, so we’ve 
    combined instructions for all 3 in the following procedure. In most cases, Lucent 
    recommends leaving the default settings in fields that aren’t specifically 
    mentioned in the following instructions. Your Lucent representative or network 
    service provider can give you more information. Your settings in the following 
    fields must match your provider’s settings:
    nDirection
    nComm Type
    nTrunk Type
    !CAUTION:
    Use the list above as a starting point and talk to your service provider. 
    Depending on your particular application, you may need to coordinate 
    additional administration with your service provider.

    Before you start
    Before you can administer any trunk group, you must have one or more circuit 
    packs of the correct type with enough open ports to handle the number of trunks 
    you need to add. To find out what circuit packs you need, refer to the DEFINITY 
    ECS System Description.
    Instructions
    As an example, let’s set up a two-way CO trunk group that carries voice and 
    voice-grade data only. Incoming calls terminate to an attendant during business 
    hours and to a night service destination the rest of the time
    To add the new CO trunk-group:
    1. Type 
    add trunk-group next and press RETURN.
    The Trunk Group
     screen appears. The system assigns the next available 
    trunk group number to this group. In our example, we’re adding trunk 
    group 5.
    2. In the Group Type field, type 
    co.
    This field specifies the kind of trunk group you’re creating.
    3. In the Group Name field, type 
    Outside calls.
    This name will be displayed, along with the group number, for outgoing 
    calls if you set the Outgoing Display? field to y. You can type any name up 
    to 27 characters long in this field.

    4. Type 85 in the COR field.
    This field controls which users can make and receive calls over this trunk 
    group. Assign a class of restriction that’s appropriate for the COR calling 
    permissions administered on your system.
    5. In the TAC field, type 
    105.
    This field defines a unique code that you or your users can dial to access 
    this trunk group. The code also identifies this trunk group in call detail 
    reports.
    6. In the Direction field, type 
    two-way.
    This field defines the direction of traffic flow on this trunk group.
    7. Type 
    1234 in the Night Service field.
    This field assigns an extension to which calls are routed outside of business 
    hours.
    8. In the Incoming Destination field, type 
    attd. 
    This field assigns an extension to which incoming calls are routed during 
    business hours. By entering attd in this field, incoming calls go to the 
    attendant and the system treats the calls as Listed Directory Number calls.
    9. In the Comm Type field, type 
    voice.
    This field defines whether a trunk group can carry voice, data, or both. 
    Analog trunks only carry voice and voice-grade data.
    10. In the Trunk Type field, type 
    ground-start.
    This field tells the system what kind of signaling to use on this trunk group. 
    To prevent glare, ground start signaling is recommended for most two-way 
    CO, FX, and WATS trunk groups.
    11. In the Outgoing Dial Type field, type 
    tone.
    This field tells the switch how digits are to be transmitted for outgoing 
    calls. Entering tone actually allows the trunk group to support both DTMF 
    and rotary signals, so Lucent recommends that you always put tone in this 
    field.
    12. In the Trunk Termination field, type 
    rc.
    Use rc in this field when the distance to the central office or the switch at 
    the other end of the trunk is more than 3,000 feet. Check with your service 
    provider if you’re not sure of the distance to your central office.
    13. Press 
    ENTER to save your changes.
    Now you’re ready to add trunks to this trunk group. Refer to ‘‘
    Adding trunks to a 
    trunk group’’ on page 368.

    Adding a DID trunk group
    In most cases, Lucent recommends leaving the default settings in fields that aren’t 
    specifically mentioned in the following instructions. Your Lucent representative 
    or network service provider can give you more information. For Direct Inward 
    Dialing (DID) trunk groups, settings in the following fields must match your 
    provider’s settings:
    nDirection
    nComm Type
    nTrunk Type
    nExpected Digits (only if the digits your provider sends do not match your 
    dial plan) 
    !CAUTION:
    Use the list above as a starting point and talk to your service provider. 
    Depending on your particular application, you may need to coordinate 
    additional administration with your service provider.
    Before you start
    Before you can administer any trunk group, you must have one or more circuit 
    packs of the correct type with enough open ports to handle the number of trunks 
    you need to add. To find out what circuit packs you need, refer to the DEFINITY 
    ECS System Description.
    Tip:
    In the DID/Tie/ISDN Intercept Treatment field on the Feature-Related 
    System parameters screen, enter 
    attd. Incoming calls to invalid extensions 
    will be routed to the attendant.
