Managing trunks 337 Tips for working with trunk groups 12 DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 12 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 1394. 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.

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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing trunks 339 Tips for working with trunk groups 12 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
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing trunks 340 Adding a CO, FX, or WATS trunk group 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 173 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.

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 355.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing trunks 343 Adding a DID trunk group 12 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. Instructions To add the new Direct Inward Dialing (DID) 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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing trunks 345 Adding a DIOD trunk group 12 9. 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 355. Related topics Refer to ‘‘ Inserting and absorbing digits’’ on page 359 for instructions on matching modifying incoming digit strings to match your dial plan. Adding a DIOD trunk group Administration for Direct Inward and Outward Dialing (DIOD) trunk groups varies from country to country. Refer to DEFINITY ECS Application Notes for Type Approval, and use the DS1 screen illustrations in the chapter for your country as a model for your administration. Remember that the central office serving your switch may be emulating another country’s network protocol. If so, you’ll have to administer your circuit packs and trunk groups to match the protocol used by your central office. !SECURITY ALERT: If you’re using Incoming Caller ID (ICLID) on analog trunks connected to a DIOD Central Office trunk circuit pack, DO NOT put these trunks in an outgoing AAR or ARS route pattern. Since the loop-start trunks supported on the DIOD Central Office trunk circuit pack do not provide answer supervision, the potential for toll fraud exists. Adding a PCOL trunk group In most cases, when administering Personal Central Office Line (PCOL) trunk groups, 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: nTrunk Type nTrunk Direction !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.
