A system for isolating portions of a computer program in a telecommunication system that receives messages from a variety of hardware or software platforms. A generic protocol converter (,) receives the message and selects a set of tables (,) based upon the platform of the source or destination of the message. A table within the table set is selected based on the direction of the message. Within each table is a listing of subroutines that are associated with a particular message. The protocol converter calls the appropriate subroutine within a main application program (,) to handle the message. Because the tables are grouped by protocol types, a change to the application program involving one protocol type does not require recompiling or retesting of application programs or subroutines associated with other protocols.

Generic distributed protocol converter

A method for communicating configuration information between two interface devices connected to a communication link in a system in which each device is capable of generating and recognizing an alarm indication signal (AIS) indicating that the device generating the AIS is not available for communication. In a communication system utilizing the present invention, each interface device is capable of modulating the AIS signal and recognizing a modulated AIS signal. A first modulation pattern is used to establish communication between devices with incompatible configurations. Configuration information is then sent from one of the devices by utilizing a second modulation pattern.
