Abstract:
A telecommunication system for isolating code segments of a computer program that transmits and receives messages associated with a telephone call between a source and destination that operate according to one of a plurality of protocols, comprising:one or more central processing units that are controlled by a computer program that comprises isolated code segments designed for each of the plurality of protocols; anda generic protocol converter receives incoming messages comprising an indication of the source and destination of the telephone call, the generic protocol converter comprising a plurality of table sets, each table set being defined for one of the plurality of protocols, each table set comprising a mapping of a plurality of isolated code segments in the computer program to the message that is received in one of the plurality of protocols, each said isolated code segment implementing a different protocol and being separately changeable from other isolated code segments, wherein the isolated code segments associated with one of the plurality of protocols may be separately changed via compilation or other code change procedures without recompiling the isolated code segments associated with the other plurality of protocols; andthe generic protocol converter operating to select a table based on the protocol of the source or destination and to call an isolated code segment that is mapped to the message by the selected table.
