Configuring destination codes with wild cards 347
Programming Operations Guide
Follow these steps to program a long distance carrier access code into a destination code.
1 Create a route that uses a line pool containing local lines only.
2
Program the route to use a line pool containing the lines used to access the long distance
carriers.
3
Type the dialout digits, which are the same as the access digits. For example, if the access code
is 10222, the dialout digits are 10222.
4
Create a destination code 91: 9 (for outside access) and 1 (for long distance). You must use a
valid destination code. Refer to
“Using destination codes” on page 338 .
5
Set Absorbed Length to 1.
The digit 9 is only used internally and should be dropped. The 1 is needed to direct the call to
the public carrier network.
TIPS: The destination codes 9 and 91 used in the examples cannot be used together. If you need
the destination code 91 to direct long distance calls, you must create a separate set of codes that
use local calling routes. These codes would be, for example, 90, 92, 93, 94, 95, 96, 97, 98 and 99.
Refer to
“Grouping destination codes using a wild card” on page 341 for information on
programming destination codes.
Programming for least-cost routing
It can be less expensive to use another long distance carrier at a different time of day. Continuing
with the example used in the previous flowchart, the lines that supply local service in normal mode
are also used for long distance service after 6 p.m. because that is when rates become competitive.
For the system to do this automatically, you must build another route.
Follow these steps to build a route for a secondary carrier:
1 Beside Route: enter an available route number.
2
Choose No number for the dialout.
3 Choose the line pool that contains the local service carrier lines.
4
Now you need to create a destination code and assign the route to the Night schedule.
In this case, the change in route uses the start and stop times for Night Schedule.
5
Add 91 as a Destination code
.
6 Make sure Absorbed length is set at 1.
7
Under Night schedule: enter the route you defined in step 1.
Calls that begin with the digits 91 travel out without using the access code when the Night
schedule becomes active or when you turn it on at a control telephone.
