7. In the Incoming Dial Type field, type tone.
This field tells 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.
8. 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.
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 368.
Related topics
Refer to ‘‘
Inserting and absorbing digits’’ on page 373 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.
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 new PCOL group and administer the group as a CO 
trunk for two-way voice traffic.
To add the new PCOL group:
1. Type 
add personal-co-line next and press ENTER.
The Personal CO Line Group screen appears.
                                                                Page 1 of X

2. In the Group Type field, type co.
This field specifies the kind of trunk group you’re creating. PCOL groups 
can be administered as CO, FX, or WATS trunks.
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. (You may want to put the phone number 
here that’s assigned to this trunk.)
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.

phone. Once assigned, the Assigned Members page of the Personal CO Line 
Group screen displays member phones:
More information
Call Detail Recording
Call Detail Recording can be activated for calls on a personal CO line, but the 
CDR record does not specifically identify the call as PCOL. 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.

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.

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 ‘‘

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 367.
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.

More information
T1 recommended settings
The table below shows recommended settings for standard T1 connections to your 
local exchange carrier.
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.
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.
