Abstract:
In an operations system, an access module for mapping incoming Transaction Language 1 (TL1) protocol messages to Open Systems Interconnection (OSI) protocol messages comprising:first processing means for parsing each incoming TL1 protocol message to determine the contents of said message;store means for storing a plurality of data tables each linked relationally to other data tables, at least a first of said data tables representing an autonomous message to event map listing TL1 protocol messages and their corresponding OSI protocol messages and at least a second of said data tables representing a non-autonomous message to directive map listing TL1 protocol messages and their corresponding OSI protocol messages;second processing means for selecting a corresponding one of said data tables based on the parsed contents of said message and using the data in said selected data table to map said message into a counterpart OSI protocol message;communications means for interfacing with network elements from which said incoming TL1 messages are output and for providing said incoming TL1 messages to said first processing means; andthird processing means for receiving said mapped OSI messages and for encoding said OSI message into an Identifier Length Value (ILV) message to be used in said operations system.
