Setting up a route for local calling
An office may have different suppliers for local and long 
distance telephone service. By programming a destination 
code, any call that begins with 9, the most common dialout 
digit, will automatically use lines dedicated to local service.
The first step is to build a route (under Services/Routing 
Service/Routing).
1. At Show route: enter 001 (or any other available route 
number) 
2. Press SCAN
 to view defined routes and CLEAR to erase a 
defined route.
3. Choose the line pool that contains the lines for local 
calling.
4. Enter the DialOut digits (if any) which are needed to direct 
the call once it is connected to an external line.
Note:  For local calls only, there are no DialOut numbers. 
Compare this with Setting up a route for long distance 
calling on page 373.
5. Now you need to set up a destination code that will use this 
route during the various schedules. Since users will dial 9 
to make an external call, 9 should be the destination code. 
(Services/Routing Service/Dest Codes)
6. At Show DstCode: press ADD
 and enter 9.
Tips - If entering a code other than 9, a valid destination 
code must be used. See Dest codes on page 367.
To view existing destination codes press 
‘ before 
entering a new code.

7. Press ≠. 
The route for the first schedule appears after Normal:. 
8. Press CHANGE
 and enter the defined route number 001.
The following illustrations show the tables used for planning 
and recording routing service found in the Programming 
Record. They are filled out to match the examples of routes for 
local and long distance calling.
Recording the routes
Tip - The destination code can use a different route 
depending on which schedule is being used. Refer to Services 
in the Modular ICS 6.0 System Coordinator Guide for 
information about using schedules. 
In the current example, Route 001 is used when someone dials 
9 during normal mode. This is the mode used when the other 
Schedules are turned off.

Recording how the routes will be used
Setting up a route for long distance calling
An office may have leased lines or E&M trunks which make it 
cheaper to call long distance. 
The routing should take place automatically when the number 
of the outgoing call begins with 1.
The first step is to build a route (under Services/Routing 
Service/Routing).
1. At Route:, enter 002 (or any other available route number) 
2. Choose the line pool where the discounted lines for calling 
long distance have been placed. Example: Line pool B.
3. Then you need to assign the route to the destination code 
and to the destination code schedules. (under Services/
Routing Service/Dest Codes)
4. At DstCode: enter a valid destination code. Example: 1
Refer to Dest codes on page 367.

6. Press CHANGE
 and enter the defined route number 002.
7. Press ≠. 
The AbsorbLength prompt appears. The default is All.
8. Press CHANGE
 to choose the number of digits that need to 
be absorbed before dialout. In this case, it would be 0, as 1 
needs to be dialed out before the rest of the digits.
Tip - To view existing destination codes press ‘ 
before entering a new code.
Tip - The destination code can use a different route 
depending on which schedule is being used. Refer to Services 
in the Modular ICS 6.0 System Coordinator Guide for 
information about using schedules. In the above example, the 
system uses Route 002, which uses Line pool B, to take 
advantage of the lower cost when the system is in normal 
mode.
Tips - The digit absorption setting (AbsorbLength) only 
applies to a maximum of two schedules.
Setting 
AbsorbLength to 0 (zero) minimizes the effort 
involved in preparing destination codes.With a 0 setting, the 
actual digits dialed by a caller are preserved in the dialout 
sequence. Programming a DialOut sequence as part of the 
route is not necessary.

Adding a long distance carrier access code
In many cases, long distance service uses the same lines as 
local service but the call is switched to a specific carrier using 
an access number. This number is sometimes called an equal 
access code. Programming for routing can include this access 
number so users only need to dial the set number, as described 
below:
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.
a. Enter the DialOut digits, which are the same as the 
carrier code digits. For example, if the access code was 
10222, the DialOut digits would be 10222.
Carrier codes are defined in Carrier Codes on page 422.
b. Create a destination code 91. 
9 (for outside access) and 1 (for long distance). Refer to 
Dest codes on page 367 to determine a valid code.
c. Set AbsorbLength to 1. 
The 9 is only used internally and should be dropped . 
The 1 is needed to direct the call to the public carrier 
network.
Tips - If rates change depending on the time of the day or 
week, a different route can be used for the same destination 
code 1 when a particular schedule is in use. See Programming 
for least cost routing on page 377.

Using destination codes to make a call
Tips - The destination codes 9 and 91 used in the examples 
cannot be used together. If the destination code 91 is needed 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. See Wild card 
character on page 368 for information on programming 
destination codes.

Programming for least cost routing
It may be cheaper to use another long distance carrier at 
another time of day. 
Continuing with the example used in the previous flowchart, 
the lines that supply local service in normal mode will also be 
used for long distance service after 6 p.m. because that is when 
rates become competitive. For the system to do this 
automatically, another route has to be built.
1. At Route: choose Route 007 (or any available route). 
2. Press ≠. 
3. At DialOut, press CLR
 to choose No numbr.
4. Press ≠. 
5. Choose Line pool A, or the pool with the local service 
carrier lines.
In this case, the change in route uses the start and stop 
times for Night Sched.
6. Return to the Routes heading and press ‘ to find 
the Dest Code heading.
7. Press ≠ and then ‘.
8. At DstCode:, press ADD
, then enter 91.
9. Press ≠ and then ‘.
10. Under Night rte: enter Route 007.
11. Press ≠.
12. Set AbsorbLength to 1.
The 9 will be absorbed before the number is dialed out to 
the network. This means, that when the Night schedule is

chosen, either automatically, by time, or manually from a 
control telephone, the calls dialed with 91 will dial out to 
the long distance network without requiring a special 
access code.
Sched:Night
Indicate how the alternate routing should be activated for each 
of the schedules.
Service
Use ≠, CHANGE
, and ‘ to change the setting 
for each schedule to one of these settings: Off, Automatic, or 
Manual.
Off — prevents the routing service from being activated. In 
this case, the Normal schedule is used.
Auto — allows you to program a stop and start time for a 
service. You will be prompted to enter start and stop times.
You can still start and stop the service by entering the 
appropriate Services feature code at a control telephone.
Manual — allows you to turn the service on and off at any 
time from a control telephone using the Ringing service 
feature code.
Refer to the Modular ICS 6.0 Coordinator Guide for a 
description of the feature codes used to work with Services.

Overflow routing
If all the lines used by a route are busy when a call is made, the 
mode may be programmed to overflow to the route used for 
normal mode. If this happens, the set will sound a warning 
tone and display the message Expensive route. The caller 
can then release the call to avoid using the normal route, or 
continue with the call.
Overflow routing is turned on or off for each schedule when 
you program the destination codes schedule. 
Press CHANGE
 to select the setting: Y (Yes) or N (No).
Refer to the Overflow call routing section of the Modular ICS 
6.0 Coordinator Guide for details about how to set up 
overflow routing.
Tips - A schedule must be active for overflow routing to 
be in effect. Overflow routing is not available in normal mode. 
You must create an overflow route to be used with each 
destination code. In this way, every route used with a 
scheduled mode that has overflow service must have an 
alternate route in normal service.

Using dialing restrictions with routing
Routing service can be further customized by adding dialing 
filters to lines in line pools. Filters restrict the use of the line to 
specific area codes. See Restriction filters on page 86 and the 
Programming chapter of the Modular ICS 6.0 System 
Coordinator Guide for more information.
Tips - Host system signaling codes can be part of the 
DialOut. See the Modular ICS 6.0 System Coordinator Guide 
for details on host system signaling codes.
Tips - You can also use routing as an alternate method for 
a direct-dial number. For example, create a destination code 
0 and program the number of the internal or external 
destination as the DialOut. Digit absorption should be set to 1.
Because overflow routing directs calls using alternate line 
pools, a call may be affected by different line filters when it is 
handled by overflow routing.
