More information
The table below summarizes field settings on the DS1 screen for the T1 and E1 
service emulated for IP Trunk service.
Creating an IP trunk 
groupUse this procedure to add a trunk group for IP trunks. You can administer multiple 
trunk groups on one IP Trunk circuit pack. Each trunk group is assigned to virtual 
ports, or channels, on the IP Trunk circuit pack, and your routing plan directs calls to 
certain trunks.
!CAUTION:
The fields described in the following procedure must be completed as shown. 
If they are not, the IP Trunk service may not work properly. Other fields may 
be completed as appropriate for your system.
As an example, add trunk group 5 and assign 12 ports for a virtual connection to the 
IP Trunk circuit pack:

Note:Depending on how the routing between sites is administered, inserting 
digits may be required. The example shows a 9 being inserted in front 
of any digits received from the IP Trunk. In most DEFINITY ECS 
switches, this is the access code for ARS and will allow the digits 
received on the trunk to be analyzed and rerouted based on ARS analysis 
table entries.
2  Enter the field values as shown in the screen diagram above.
Note:All IP trunk groups are administered as DS1 tie trunks (Group Type = 
tie).
3  Move to the Trunk Features page and type n in the Maintenance Tests field.
4  In the Suppress # Outpulsing field, type y.
Note:You may need to fill in other fields for your system.
5  Move to the Group Member Assignments page and add the ports (channels) 
you’ve purchased.
You’re assigning virtual ports, or channels, to the IP Trunk circuit pack. Each 
channel can carry one call at a time. The number of ports you can use is limited to 
the maximum number specified in your license.

Administer AAR/ARSYou can use Automatic Alternate Routing (AAR) and Automatic Route Selection 
(ARS) to route calls over an IP trunk group just like any other trunk group. Unlike 
other trunk groups, however, you must administer both the DEFINITY ECS switch 
software and Configuration Manager to route calls over IP trunks. DEFINITY ECS 
uses the dialed digit string to select a route pattern — and thus a trunk group — for 
each call. The IP Trunk software matches each trunk line or each dialed string to a 
specific IP address.
The following administration needs to be performed on both the origin and 
destination switches — if you can’t administer the remote switch, coordinate this 
work with the administrator at the other site. The following general instructions 
assume that you know how to use Automatic Alternate Routing (AAR) and 
Automatic Route Selection (ARS) to route conventional calls.
To administer IP call routing on DEFINITY ECS:
1  Administer the AAR and ARS Digit Analysis Table on DEFINITY ECS with the 
information you entered in the Switch Admin tables on the worksheet.
2  After you’ve assigned a route pattern in the AAR or ARS Digit Analysis Table, 
add the IP trunk group to that route pattern if you haven’t already done so
3  Make the IP trunk group the first preference in the route pattern and perform any 
other administration required on the Route Pattern screen.
Note:If you want to route calls over the normal telephone network when 
transmission quality over the IP network is unacceptable, assign one or 
more conventional trunk groups to the route pattern as backups.
DEFINITY ECS will route appropriate calls to the IP trunk group. Now you need to 
administer Configuration Manager to route outgoing and incoming calls 
appropriately.

The Maximum Digits to be collected field entry will be determined by the type of 
dialing, or types of dialing that will be performed using IP Trunking. Refer to the 
Dial/Routing Plan Worksheets, or if extension dialing is used, this field would be 
the extension length in the DEFINITY private network.
!CAUTION:
Set this field no higher than the maximum length of the digit string the switch 
sends. Otherwise, the IP Trunk application waits several seconds for 
additional digits and users experience delays.

7  In the Add Originating Entry dialog box, you enter information that routes the call 
data between originating and terminating locations. You need to enter information 
that allows the IP Trunk to route calls based on dialed digits or on the line (port) 
that a call arrives on.
Note:It is not possible to mix dialing strategies in the IP Trunk software. Once 
line numbers are used to route calls, line numbers must be used on ALL 
entries in a routing table.
Routing information entered will be based on information that has been entered 
on the Dial/Routing Plan Worksheets, or on information collected based on the 
Procedures for Extension Dialing Between Sites.
Routing based on Dialed String
If routing will be based on dialed string, enter any in the Line Number field, then 
enter the information from the worksheets or a unique identifier for an extension 
range from the Procedures for Extension Dialing.
Routing based on Line Numbers
If routing will be based on line numbers that are dedicated to a specific location, 
you need to make sure that the same line number is used on both the originating 
and destination switches. This is done by prepending a string of digits unique to a 
line and associating it with that line number at both the originating and 
terminating IP Trunks. This code will be discarded at the terminating end.
For example, in the display above, the code number 01 is entered in the Replace 
Digits field as a unique digit string that will be associated with line number 1. If 
none is entered in the Search Digits field, no digits will be searched for. We don’t 
need to search for dialed digits because the line numbers, which are associated 
with port numbers on the circuit pack, are dedicated in a DEFINITY trunk group 
to a particular location. Any digits received on these lines will always be routed to 
the same location. The only requirement is to prepend digits in the replace digits 
field to ensure that a call placed on a line (port) at the originating end can be 
terminated on the same line at the destination end. The digits prepended at the 
originating end and searched for at the terminating end must be the same.
Note:Any digits searched for must also be replaced if they are used to complete 
the routing of a call. If digit substitution will be needed, it may be 
necessary to put a digit string in the Search Digits field, and substitute 
those with new digits in the Replace Digits field.
8  For Entry Type, enter accept to allow incoming calls.
9  In the Search Digits field, type the digits entered in the Originating Search string 
box for this site in the Dial/Routing Plan Worksheets, or follow the Procedures for 
Extension Dialing Between Sites.
10  In the Replace Digits field, type the digits entered in the Originating Replace 
string box for this site in the Dial/Routing Plan Worksheets, or follow the 
Procedures for Extension Dialing Between Sites.
11  In the Destination Type field, select the appropriate value for the remote switch.
Select ITS R1.2 if the other switch uses IP Trunk.
