Assigning ARS FAC
Be sure the ARS Feature Access Code (FAC) is set up on your system. In the U.S., 
9 is usually the ARS FAC. Users dial 9 to make an outgoing call. 
When a user dials 9 to access ARS and make an outgoing call, the ARS access 
code 9 is dropped before digit analysis takes place. will not be part of the digit 
analysis.
Instructions
To assign the ARS FAC:
1. Type 
change dialplan and press ENTER.
The Dial Plan Record
 screen appears.
2. Move to the 9 row and type 
fac in the first column. Press ENTER to save 
your changes.
3. Type

Understanding ARS analysis
With ARS, the switch checks the digits in the number called against the ARS 
Digit Analysis Table to determine how to handle the dialed digits. Your switch 
also uses Class of Restriction (COR) and Facility Restriction Level (FRL) to 
determine the calling privileges.
Let’s look at a very simple AAR and ARS Digit Analysis Table
. Your system 
likely has more defined dialed strings than our example.
The far-left column of the ARS Digit Analysis Table lists the first digits in the 
dialed string. When a user makes an outgoing call, the system analyzes the digits, 
looks for a match in the table, and uses the information in the matching row to 
determine how to route the call.
Let’s say a caller places a call to 1-303-233-1000. The switch matches the dialed 
digits with those in the first column of the table. In this example, the dialed string 
matches the ‘1’. Then the systems matches the length of the entire dialed string 
(11 digits) to the minimum and maximum length columns. In our example, the 
11-digit call that started with 1 follows route pattern 30 as an fnpa call.
Tip:
The first dialed digit for an external call is often an access code. If ‘9’ is 
defined as the ARS access code, the switch drops this digit and analyzes the 
remaining digits with the ARS Analysis Table.
The Route Pattern points to the route that handles the calls that match this dial 
string.
Call Type tells what kind of call is made with this dial string. Call type helps the 
switch decide how to handle the dialed string.

Examples of digit conversion
Your system uses the AAR or ARS Digit Conversion Table to change a dialed 
number for more efficient routing. Digits may be inserted or deleted from the 
dialed number. For instance, you can tell the switch to delete a 1 and an area code 
on calls to one of your locations, and avoid long-distance charges by routing the 
call over your private network.
The table below reflects these values:
nARS feature access code = 9
AAR feature access code = 8
Private Network Office Code (also known as Home RNX) = 222
Prefix 1 is required on all long-distance DDD calls
Dashes (-) are for readability only
The switch maps the dialed digits to the matching pattern that most closely 
matches the dialed number. Example: If the dialed string is 957-1234 and 
matching patterns 957-1 and 957-123 are in the table, the match is on pattern 
957-123.

Defining operator assisted calls
Let’s look at how the switch routes an ARS call that begins with 0 and requires 
operator assistance. Remember, the user dials 9 to access ARS, then a 0, then the 
rest of the number.
To see how your switch handles a call to an operator:
1. Type 
display ars analysis 0 and press ENTER. 
The AAR and ARS Digit Analysis Table
 screen starting with 0 appears.
The table in our example shows 6 translations for calls that begin with 0. 
Instructions
Let’s use the ARS digit analysis table shown above and follow the routing for an 
operator assisted a call to NJ.
— A user dials 9 0 908 956 1234. 
— The switch drops the ARS FAC (9 in our example), looks at the ARS Digit 
Analysis Table for 0, and analyzes the number. The switch:
ndetermines that more than 1 digit was dialed
nrules out the plan for 00, 01, and 011
ndetermines that 11 digits were dialed
— The switch routes the call to route pattern 1 as an operator assisted call

Defining Inter-exchange carrier calls
Let’s look at how the switch routes an ARS call to an inter-exchange 
(long-distance) carrier (IXC). IXC numbers directly access your long-distance 
carrier lines. 
IXC numbers begin with 1010, followed by three digits, plus the number as it is 
normally dialed including 0, 00, or 1+ 10 digits. These numbers are set up on your 
default translations.
Remember, the user dials 9 to access ARS, then the rest of the number.
Instructions
To see how your switch handles a call to an IXC:
1. Type 
display ars analysis 1 and press ENTER. 
The AAR and ARS Digit Analysis Table
 screen starting with 1 appears.
This table shows 5 translations for IXC calls. 
When you use x in the Dialed String field, the switch recognizes x as a wildcard. 
The x represents any digit, 0 - 9. If I dial 1010, the next 3 digits will always match 
the x wild cards in the dialed string. 
Use the ARS digit analysis table shown above and follow the routing for an IXC 
call to AT&T. 1010288 is the carrier access code for AT&T.
— A user dials 9 1010288 plus a public network number.
— The switch drops the ARS FAC (9 in our example), looks at the ARS Digit 
Analysis Table for 1010, and analyzes the number. 
— The switch matches 288 with xxx and sends the call over route pattern 5.

Restricted area codes and prefixes
Certain area code numbers are set aside in the North American Numbering Plan. 
These numbers are 200, 300, 400, 500, 600, 700, 800, 877, 888, 900. You need to 
specifically deny calls made to area codes 200 through 900 (except 800 and 888). 
You can also deny access to the 976 prefix, which is set aside in each area code for 
pay-per call services, if you do not want to incur charges. You can block 976 or 
any other prefix in all NPAs with a single entry in the digit analysis table. See 
‘‘
Using wild cards’’ on page 194 for more information.
Instructions
Set the 200 area code apart from other area codes 201 through 209. We use the 
digit analysis table 120 because it defines long distance calls that begin with 1 and 
all area codes from 200 through 209. 
To deny long distance calls to the 200 area code:
1. Type 
change ars analysis 120 and press ENTER.
The AAR and ARS Digit Analysis Table
 screen beginning with 120 
appears.
The table in our example shows 2 translations for calls that begin with 120. 
First, follow the routing for a long-distance call that begins with 120 and is 
allowed. The 120 translation handles all dial strings 1-201 through 1-209, and 
there are many matches.
— A user dials 9 120 plus 8 digits (the first of the 8 digits is not 0).
— The switch drops the ARS FAC (9 in our example), looks at the ARS Digit 
Analysis Table for 120, and analyzes the number. The switch determines 
that the call is a long-distance call and sends the call over route pattern 4.
Now let’s follow a call that begins with the restricted area code 200. Only one 
string matches this translation.
— A user dials 9 1200 plus 7 digits.
— The switch drops the ARS FAC (9), and looks at the ARS Digit Analysis 
Table for 1200. The switch determines that the call type is deny and the call 
does not go through.

Using wild cards
You can use wild cards to help separate out calls to certain numbers. Remember, 
when you use the wild card x in the Dialed String field, the switch recognizes x as 
any digit, 0 - 9. For example, you can restrict users from making calls to a 555 
information operator where you might incur charges. 
Instructions
To prevent callers from placing calls to long-distance 555 information numbers:
1. Type

Setting up multiple locations
When you define location numbers for the cabinets in a switch, you can create 
numbering plans and time zone and daylight savings plans that are specific for 
each cabinet. Choose the location you want to use as your main location, and 
offset the system clock time on each cabinet according to their its location.
Before you start
Be sure the Multiple Locations field on the System-Parameters Customer-Options 
screen is set to 
y. If this field is set to n, contact your Lucent representative for 
more information.
Be sure your daylight savings rules are administered. Daylight Savings Rule 
numbers are located on the Daylight Savings Rule Screen 
Each cabinet in a switch and each port network in the cabinet must be assigned a 
location number. Refer to the maintenance information for your switch for more 
information.

Instructions
For example, let’s set up multiple locations for a switch with cabinets in Chicago 
and New York. Location 1 is assigned to the cabinet in Chicago, our main office, 
so Central Standard Time is used for our main location. Location 2 is assigned to 
the cabinet in New York. We’ll define the numbering plan area (NPA) for the 
Chicago and New York locations, and set the time zone offset for NY to show the 
difference in time between Eastern Standard Time and Central Standard Time.
Tip:
