DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Routing outgoing calls 177 Understanding ARS analysis 8 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. Table 3.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Routing outgoing calls 178 Understanding ARS analysis 8 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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Routing outgoing calls 179 Understanding ARS analysis 8 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).

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Routing outgoing calls 180 Understanding ARS analysis 8 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 181 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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Routing outgoing calls 181 Understanding ARS analysis 8 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 change ars analysis 1 and press RETU RN. The AAR and ARS Digit Analysis Table screen beginning with 1 appears. 2. Use the arrow keys to move to a blank Dialed String field. 3. Enter 1xxx555 in the Dialed String field. 4.

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.

AAR or ARS must be administered.
nFor AAR, verify that either the Private Networking field or the Uniform
Dialing Plan field is y on the System-Parameters Customer-Options screen.
nFor ARS, verify that the ARS field is y on the System-Parameters
Customer-Options screen.
Each cabinet in a switch must be assigned a location number. Refer to the
maintenance information for your switch for more information.
Instructions
For example, let’s use ARS to set up local call routing for two switch locations.
Our Chicago switch is assigned to location 1, and our New York switch is
assigned to location 2.
Our example shows a simple local dialing plan. Each location already contains
location-specific routing tables. We’ll use route pattern 1 for local service calls
and route pattern 2 for local HNPA calls in the Chicago location.
Tip:
Create location-specific routing by assigning different route patterns for
each location.
To define local calls for switches in Chicago and New York:
1. Type
change ars analysis location 1 and press ENTER.
The AAR and ARS Digit Analysis Table
