4. In the TAC field, type 111.
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.
5. 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.
6. In the Trunk Port field, type
01D1901.
This is the port to which the trunk is connected.
7. 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.
8. 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.
9. Press
ENTER to save your changes.
You assign phones to a PCOL group by administering a CO Line button on each
phone. Once assigned, the Assigned Members page of the Personal CO Line
Group screen displays member phones:

Calls over personal CO lines can, however, be identified by the trunk access code used on the call. The call is recorded to the extension number assigned to the phone where the call was originated or answered. Restrictions nAbbreviated Dialing can be used with a personal CO line, but the accessed lists are associated with the individual phones. nAuto Hold and Leave Word Calling do not work with calls on a personal CO line. nSend All Calls cannot be activated for a personal CO line. nINTUITY AUDIX cannot be in the coverage path of a PCOL group. nOnly phones in the same PCOL group can bridge onto calls on the personal CO line. If a user is active on his or her primary extension number on a PCOL call, bridged call appearances of that extension number cannot be used to bridge onto the call. nWhen a user puts a call on hold on a personal CO line, the status lamp associated with the PCOL button does not track the busy/idle status of the line. Adding a Tie or Access 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. Your settings in the following fields must match your provider’s settings (or the setting on the far-end switch, if this is a private network trunk group): 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.
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
As an example, let’s add a two-way tie trunk group that supports voice and
voice-grade data.
To add the new tie 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
tie.
This field specifies the kind of trunk group you’re creating.

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 or 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 users can dial to access this trunk group. 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 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. If you’re administering a T1 connection in North America, type rbavd in this field. 9. In the Trunk Type field, type wink/wink. This field tells the system what kind of signaling to use on this trunk group. Because we’re receiving and sending digits over this trunk group, we’re using wink/wink signaling to minimize the chance of losing part of the digit string in either direction. 10. Type tone in both the Outgoing Dial Type and Incoming Dial Type fields. These fields tell the switch how digits are transmitted for incoming 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. 11. 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 351 Setting up digital trunks 12 Setting up digital trunks Any of the common trunks, except for PCOL trunks, can be analog or digital. (PCOL trunks can only be analog.) Administering a digital trunk group is very similar to administering its analog counterpart, but digital trunks must connect to a DS1 circuit pack and this circuit pack must be administered separately. The example in this section shows you how to do this. 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: nBit Rate nLine Coding (unless you’re using a channel service unit to convert between your line coding method and your provider’s) nFraming Mode nSignaling Mode nInterface Companding !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 Assign the DS1 circuit pack before you administer the members of the associated trunk groups. !CAUTION: If enhanced DS1 administration is not enabled, you cannot make changes to the DS1 Circuit Pack form before you remove related member translations of all trunks from the trunk group. Refer to ‘‘ Enhanced DS1 administration’’ on page 353. Before you can administer a digital trunk group, you must have one or more circuit packs that support DS1 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
The following example shows a DS1 circuit pack configured for T1 service. The
circuit pack is supporting a two-way CO trunk group that carries only voice and
voice-grade data.
To configure a new DS1 circuit pack:
1. Type
add ds1 07A19 and press ENTER.
The DS1 Circuit Pack
screen appears. You must enter a specific port
address for the circuit pack.
2. Type
two-way CO in the Name field.
Use this name to record useful information such as the type of trunk group
associated with this circuit pack or its destination.
3. In the Bit Rate field, type
1.544.
This is the standard for T1 lines.
4. In the Line Coding field, type
b8zs.
Lucent recommends you use b8zs whenever your service provider supports
it. Since this trunk group only carries voice traffic, you could also use
ami-zcs without a problem.
5. In the Framing Mode field, type
esf.
Lucent recommends you use esf whenever your service provider supports
it.
6. In the Signaling Mode field, type
robbed-bit.
7. In the Interface Companding field, type
mulaw.
This is the standard for T1 lines in North America.
8. Press

If you use b8zs line coding and esf framing, it will be easier to upgrade your T1 facility to ISDN should you want to. You can upgrade without reconfiguring external channel service units, and your service provider won’t have to reconfigure your network connection. E1 recommended settings DS1 administration for E1 service 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. NOTE: 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. Enhanced DS1 administration Normally, you can’t change the DS1 Circuit Pack screen unless you remove all related trunks from their trunk group. However, if the DS1 MSP field on the System-Parameters Customer-Options screen is y and you are assigned the associated login permissions, you can change some of the fields on the DS1 Circuit Pack screen without removing the related trunks from their trunk group. Field Value Notes Line Coding b8zs Use ami-zcs if b8zs is not available. Signaling Mode robbed-bit Robbed-bit signaling gives you 56K bandwidth per channel. If you need a 64K clear channel for applications like asynchronous data transmission or remote administration access, use common channel signaling. Framing esf Use d4 if esf is not available.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Managing trunks 354 Setting up digital trunks 12 The following enhanced DS1 administration login permissions must be assigned on the Command Permission Categories screen: nThe Maintain Enhanced DS1 field must be y. nThe Maintain Trunks field must be y. nThe Maintain Switch Circuit Packs field must be y. If you busy out the DS1 circuit pack, you can change the following fields: CRC, Connect, Country Protocol, Framing Mode, Interface, Interconnect, Line Coding, and Protocol Version. After changing these fields, you may also have to change and resubmit associated screens. Matching field settings on different screens For enhanced DS1 administration, some field values on the DS1 Circuit Pack screen must be consistent with those on other screens as shown in the table below. If you change field values on the DS1 screen, you must change the related fields on the other screens and resubmit them. Refer to DEFINITY ECS Administration for Network Connectivity for information on the Signaling Group screen. Specific combinations of settings for some of these fields are shown below.
