TL1 Message Parser Java Bean
Network and Element Management Systems as well as Craft Interface Terminal applications need to interface with Network Elements supporting the Transaction Language 1 (TL1) interface. To help fill this need, QCOM has developed the TL1 Message Parser Java Bean. It provides parsing of TL1 Output messages including Acknowledgements, Command Responses, and Autonomous messages. The TL1 syntax supported is per Telecordia standard, GR-831-CORE.Note that the QCOM TL1 Message Parser provides a generic TL1 parser, which parses the TL1 message into the standard output syntax components (e.g. parameters, text blocks, header). Thus, the Parser can work with any standard TL1 message. However, this output, while standard, is not TL1 message specific (e.g. REPT ALM). QCOM provides an add-on tool called, TL1MsgGen, which reads a TL1 message specification file (such as GR-833) and generates Java classes for each specific TL1 message (e.g. REPT_ALM_automsg). These generated classes make the developer's job easier and the code is much easier to read and maintain, because the generated classes refer to the specific message parameters (e.g. REPT ALM ntfcncde and srveff).
Features
The TL1 Message Parser provides the following functionality:
- Parses TL1 Output Messages including:
- Acknowledgements such as IP, PF, RL
- Autonomous messages (e.g. REPT ALM)
- Response messages (e.g. RTRV-ALM response)
- Exceptions are generated if the message is detected to be invalid.
- Non-standard TL1 syntax support
- Allows user customizations to support non-standard TL1 syntax
- Built-in support for non-standard 4-digit years in the header
- Packaged as a configurable Java Bean; Available for any Java-enabled platform
- Maps via a user specification the parameter blocks and values to the specific message parameter’s names and values (using the separate TL1MsgGen tool)
