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 Figure 90, 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.

To build a route for a secondary carrier

1 Create a route for the trunks and assign it to the Normal schedule. Refer to “Setting up a route

through a dedicated trunk” on page 286.

2 Choose No number for the dial-out.

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 Create 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.

Using multiple routes and overflow routing

If all the lines used by a route specified by a destination code are busy when a call is made, you can

program other routes that the system automatically flows the calls to, or you can allow the call to

overflow directly to the Normal route schedule (usually the most expensive route). However, this

only takes effect if an active schedule is applied to the line. Overflow routing is not available in

Normal mode.

You must create overflow routes for each destination code for which you want to allow overflow

routing.

Tips: To minimize the effort involved in preparing destination codes, set the digit

absorption to 0. When digital absorption is set to 0, the actual digits dialed by a caller are

preserved in the dial-out sequence. The need to program a dial out sequence as part of the

route depends on the required dialout.
