Abstract
In a telecommunication switching system, an apparatus for automatically converting ISDN codeset and codepoint protocol in messages transmitted to the telecommunication switching system from a plurality of other telecommunication switching systems each using a diffrent ISDN codeset and codepoint protcol than the telecommunication switching system to identify the same data information. All telecommunication switching systems are interconnected by data channels. Further, the apparatus is responsive to another ISDN message generated by the telecommunications switching system for transmission to another one of the plurality of telecommunication switching systems to convert the codeset and codepoint protocol of the other message to the codepoint and codeset protocol of the other one of the plurality of telecommunication switching systems. The conversions are performed by using sets of conversion tables each identified with an ISDN data channel, and the identity of the data channel is used to select which set of tables is to be used to convert a codeset and codepoint protocol.
