Several configuration examples are offered here to show how the RCOS works.  If you were to 
configure an RCOS as in Table 8-12, the system would process dial strings as shown in the 
following examples. 

Home NPA 

408 

Starting digit position of NPA 

10 

Ending digit position of NPA 

8 

Starting digit position of NXX 

7 

Ending NXX digit position of NXX 

5 

Digits to be absorbed 

9,1,91 

Exact match table is set to disallow 

5551212,411 

NPA table is set to allow 

408,415,510 

NXX table for the NPA 408 is set to disallow 

662,684,728

 

If a dial string is 914084283558, the system: 

1.  Removes the 91 in accordance with the absorption table. 

2.  Compares to the exact match table and finds no match. 

3.  Compares the NPA 408.  Because the NPA 408 has an associated NXX table, it is used. 

4.  Places the call because the NXX table is a disallow table and does not contain the prefix 428. 

If a dial string is 2551234, the system: 

1.  Compares to the exact match table. 

2.  Adds the home NPA. 

3.  Compares the NPA 408.  Because the NPA 408 has an associated NXX table, it is used. 

4.  Places the call because the NXX table is a disallow table and does not contain the prefix 255. 

If a dial string is 14154244567, the system: 

1.  Removes the 1 in accordance with the absorption table. 

2.  Compares to the exact match table. 

3.  Compares the NPA 415.  Because the NPA 415 has an associated NXX table, it is used. 

4.  Blocks the call because the NXX table is a disallow table and contains the prefix 424. 

If a dial string is 95551212, the system: 

1.  Removes the 9 in accordance with the absorption table.
