CRAWFORD K E 1 23 METHOD OF CONTROLLING CALL TRAFFIC IN A COMMUNICATION SWITCHING SYSTEM Abstract of the Disclosure Call traffic in a stored program controlled telephone switching system is effected by performing code gapping on telephone calls to a particular called customer. Code gapping is performed by limiting the rate at which successive attempts may be made to complete all or part of a call to the particular called customer which is identified by a called customer code, such as a Plain Old Telephone Service (POTS) called customer directory code. A Minimum Time (MT), such as 10 seconds, is prescribed as the MT for the POTS number. A record is made of the Last Clock Time (LCT) at which the last earlier allowed attempt was made to complete a call to the POTS number. The Present Clock Time (PCT) is noted as the time at which completion of a subsequent call to the POTS number is presently desired. The subsequent call completion attempt is denied if the MT for the POTS number has not expired since the LCT for the POTS number; but, if the MT has expired, the subsequent call completion attempt is allowed and the PCT becomes the new LCT for the POTS number.
