What Is Claimed Is:

1. A method for processing and routing termination calls, each having a termination telephone number, comprising the steps of:
(1) receiving a termination telephone number at a telecommunication switch;
(2) sending said termination telephone number to a computer data base system in response to receiving the termination telephone number;
(3) translating the termination telephone number into a termination routing address, wherein said terrnination routing address includes a termination switch identifier, at least one digit to be outpulsed from a receiving switch having a switch identifier that corresponds to said termination switch identifier, and a termination trunk group identifier;
(4) sending said terrnination routing address to the telecommunication switch, thereby causing the telecommunication switch to process the termination call as a receiving switch;
(5) receiving said termination routing address at a receiving switch having a receiving switch identifier;
(6) comparing the receiving switch identifier and said termination switch identifier in response to receiving said termination routing address; and

(7) outpulsing said at least one digit from the receiving switch to a termination trunk group having said termination trunk group identifier, if the receiving switch identifier matches said termination switch identifier.

2. The method of claim 1, further comprising the step of:
(8) routing said termination routing address to a next receiving switch if the receiving switch identifier does not match said teπnination switch identifier, and thereafter performing at least steps (5) - (6).

3. The method of claim 1 wherein said termination trunk group identifier is a dedicated trunk group identifier.

4. The method of claim 3, wherein said at least one digit comprises only the digits to be outpulsed to a dedicated trunk group having a trunk group identifier that corresponds to said termination trunk group identifier,

5. The method of claim 4, wherein said digits to be outpulsed may be specified for each said termination telephone number.

6. The method of claim 1 wherein said termination trunk group identifier is a shared trunk group identifier.

7. The method of claim 6, wherein said at least one digit comprises a national telephone number.

8. The method of claim 6, wherein said at least one digit comprises an international telephone number.

9. In a telecommunications system having means for originating a termination call and at least one terrnination trunk group, apparatus for processing and routing termination calls, each having a termination telephone number, to the appropriate termination trunk group, comprising:
a telecommunications switch for receiving the termination call;
translating means coupled to said telecommunications switch for translating the termination telephone number into a termination routing address in response to receipt of the termination telephone number, wherein said termination routing address includes a termination switch identifier, at least one digit to be outpulsed from a receiving switch having a switch identifier that corresponds to said termination switch identifier, and a termination trunk group identifier;
a receiving switch having a receiving switch identifier for receiving said termination routing address;
comparing means coupled to said receiving switch for comparing the receiving switch identifier and said termination switch identifier; and
means coupled to said comparing means for outpulsing said at least one digit from said receiving switch to the appropriate termination trunk group when the receiving switch identifier matches said termination switch identifier.

10. The apparatus of claim 9, fiirther comprising:
means coupled to said comparing means for routing said termination routing address to a next receiving switch when said receiving switch identifier does not match said termination switch identifier.

11. The apparatus of claim 9, wherein said translating means includes a computer data base system, wherein said termination telephone number is input to the data base system and said termination routing address is output from said data base system.

12. The apparatus of claim 9, wherein said termination trunk group is a dedicated trunk group.

13. The apparatus of claim 12, wherein said at least one digit comprises only the digits to be outpulsed to the dedicated trunk group.

14. The apparatus of claim 12, wherein said digits to be outpulsed may be specified for each said termination telephone number.

15. The apparatus of claim 9, wherein said termination trunk group is a shared trunk group.

16. The apparatus of claim 15, wherein said at least one digit comprises a national or intemational telephone number.
