Abstract: A method of service code conversion and a service code conversion control circuit are disclosed for translating a dialed service access code in an abbreviated form into the directory number of a line circuit. A class-of-service indication assigned to a calling line circuit and a dialed abbreviated service access code are steered from a common register to a first translation circuit normally providing outgoing routing information for trunk marking. Instead of providing outgoing routing information, the first translation circuit or translator is strapped to recognize the class-of-service indicator and abbreviated dialed access code to enable a service code conversion control circuit. The service code conversion control directs the first translator to perform a conversion of the access code to a type of call indicator and a directory number, both of which are returned to the common register. A second translation circuit is enabled by the converted information which was returned to the common register and thereafter seizes a line circuit corresponding to the stored directory number and having a special service station terminated thereat.
