BackOnline – Helps DOCSIS engineers go to sleep sooner
BackOnline is a free open-source desktop application designed specifically for DOCSIS engineers. It aims to streamline and speed up the process of tracking and troubleshooting HFC networks.
The main functionality of the application is to analyze the output of the “show cable modem” command from the CMTS, identifying potential issues and displaying the current status of the CMTS.
Example of output of “show cable modem” on one of Casa CMTS’s:

BackOnline operates entirely offline, without any connection to network or CMTS. Users can input data by either loading text files from their local PC or copying and pasting output directly from the terminal.
The application processes the data by comparing two outputs to identify potentially missing or problematic devices.
The application also supports full integration with Excel (and similar spreadsheet programs) and offers exporting capabilities for detailed reports.

EXAMPLE TIME!
Here is an example of the application’s functionality:
- Input Data: Load data from a local file or copy and paste it from the terminal, then click the corresponding button to load the data correctly.
2. Compare Data: After loading two files for comparison, choose the type of processing from the corresponding buttons, and the output will be displayed immediately.
3. Export Reports: At the end of the analysis, export the data to an .xlsx report that presents all relevant information in a clean and well-organized look.
NOTE: This function is currently only supported for CISCO_DETAIL and CASA_DETAIL processing.
